Radioactive Welsh Lake - Legacy of Trawsfynydd

[@tjrr1999]

I apologise for my poor pronunciation of some of the Welsh locations in this, I did not intent to cause any offence. I will endeavour to improve on this point in the future.

[@nigels.6051]

I know most English people can't pronounce Welsh words, even though Welsh and it's related languages are the native languages of Britain, not English. If you want to learn about your British heritage, then you should learn something about the native languages. Normally I just laugh at the attempts, but this has to be the worst video I have ever encountered for pronunciation of Welsh! A few points to note: "Llyn" is the word for "Lake", saying "Lake Trawsfynydd Lake" sounds stupid. "Ll" is a single letter, there is no 'L' in Llyn, you need to at least attempt not to pronounce it with an 'L'. "dd" is also a single letter, there is no 'd' in Trawsfynydd, again, make an attempt at the correct letter. The name "Snowdonia" has been obsoleted, everyone is is now supposed to call it "Eryri" - another challenge for you! "Afon" starts with an "Ahh", not an "Aye". "Prysor", the 'y' is not an English 'Y", more an "Ugh". "Maentrog" - starts with "Mine" We don't expect you to get it right, but if you are going to pronounce the words/names, at least make an attempt to get close, it is not hard to look up the pronunciation online. You should also have mentioned that the most serious nuclear pollution in that area, which prevented many local farms from selling their produce for decades, was not from the Trawsfynydd power plant, but from Chernobyl. Trawsfynydd itself has released far less radioactive pollution than any coal fired power plant of its era. "The fact that coal power plants are radioactive has been established not only on the basis of scientific data, but also because some companies have specialised in salvaging uranium from the smoke the plants give off in order to resell it to the nuclear power industry". The fact that it is taking a long time to decommission is a feature, not a problem; most of the time there is very little happening, other than waiting for the radioactive elements to decay naturally and become safe. Give the facts, and the problems, but keep them in context. That power station saved the release of a billion tonnes of CO2, lots of radiation, significant quantities of arsenic, lead, thallium, mercury, uranium and thorium into the atmosphere from coal power.

[@nigels.6051]

P.S. Try to get the Welsh spellings correct too. Your description contains "Lynn Trawsfynydd." - spelt as you say it, not correctly spelt!

[@BionicRusty]

No problem, buddy. For a close pronunciation use the following, Traws (say ‘trousers’ without the ers. So ‘trous’) fyn (say ‘fun’) ydd (say ‘with’ without the w. So ‘ith’) Great video. 👍

[@rodlaughton2318]

@@nigels.6051 excellent and great to hear someone debunk the myths about nuclear power pollution versus coal fired power generation! 👏

[@rockets4kids]

I am much more concerned about your sources here. I have not seen anything to suggest contamination is any worse than any other nuclear plants of the era.

[@Xantec]

not sure how the lake can become contaminated, the MAGNOX reactors were core-cooled by pressurised Carbon Dioxide, which was cooled by the steam circuit, which in turn was cooled by the lake water. The lake water did not come into contact with the core of the reactors.

[@johnj4860]

Half baked green pseudo science masquerading as information but carefully avoiding giving details of magnitudes. Exaggeration running riot as expected.

[@sticky70]

Apparently there were leaks from the cooling ponds due to joint weakness in their structure during its operational phase and some low level contamination during the refuelling and decommissioning phase but in line with authorised discharges. The caesium 137 has been found in the lakes sediment at levels considered to be trivial but that doesn’t make a good KZbin title does it! In actual fact it’s so radio active it was decided that a trout farm with fish pens would be a great Idea to introduce into the food chain!

[@allancopland1768]

Correct.

[@treebeard2220]

When I was doing A-level physics, I took some water samples from the lake. At school I placed a geiger tube over them and compared counts between the lake water, mineral water from a shop, local tap water, rain water (100 km from the lake) etc. There was no significant difference among them. I also dried out the dissolved solids and tested those. Again, no significant difference. The video notes that any contaminants are now in the lake sediments, and my testing and sampling was crude. At least, I was able to satisfy myself that the lake wasn't conspicuously radioactive compared with background.

[@MervynPartin]

The Carbon Dioxide is not normally vented into the atmosphere, except when depressurising for maintenance (2-yearly) although minor (repeat- minor) losses do occur during operation. This gas has negligible radioactivity, unless a fuel element leaks, But that is identified and removed from the reactor quite quickly. Routine monitoring of the environment is carried out by the Health Physics teams. The lake water is pumped through the turbine condensers and forms no part of the nuclear circuit. It would be used in the same quantities if the the power station had been coal fired for the same output. There are some discharges of liquid low-level radioactive waste into the water, but these are all closely monitored and have to conform to strict limits. Given a choice of living near a nuclear station or a coal/oil fired station, The healthiest option is nuclear- no acid rain or dust.

[@FowlorTheRooster1990]

The types of reactors that have been used for electricity in the UK have never taken water straight from outside the station. The gas reactors had three circuits, the primary gas loop which cooled the reactor, the secondary which is a water circuit going to the steam turbines, and finally the condenser circuit which draws water from the lake and into the turbine condenser to cool the secondary loop's water which cools the reactor's gas / water. You are highly incorrect at 1:50, the Magnox reactors DID NOT VENT to atmosphere under normal operations, as mentioned above it stays in the primary circuit with insignificant particles of it being lost, same as any other boiler in many different industries. 6:36 Source? 7:16 Every sunny day you go outside you are exposed to radiation from the sun, every second of your life, radiation. You need to specify what sort of radiation. Reactors like the BWR and PWR every once in a while dump small amounts of treated triturated water to the environment, very small controlled releases that they would be diluted in a short time and pose very little to no risk. Also along with your statement of "liquid nuclear waste" what type of nuclear waste are you talking about? as in most countries there are three classes of nuclear waste, Low Level, which is things like potentially radioactive materials, such as broken tools that may have come into contact with radioactive materials at a nuclear site. Intermediate level wastes which are quite radioactive, in this case that would be the Graphite blocks. And finally high level wastes which include things like the reactor's fuel. Around 97% of nuclear waste is actually the low level waste, of which poses little risk when compared to the high level wastes. 7:40, the USSR was known for not giving a single hoot about nuclear safety, as long as it was safe enough not to have the majority complain about it, it was allowed. In the UK, vents and water dumping is done in a controlled manner, excluding the accidental leaks at the Swarf Silos and Dounreay. The deliberate releases in the UK have been done with heavy moderation and adherence to the regulations of of the time when the releases happened, of which means the risks have been analysed so little harm to the public is ensured. And even then, given that say Tritium has a half life of about twenty years, by now after the first release you claimed, after the first half life the majority of the radioactivity it gives off would have decayed and it will keep getting safer every twenty years until it becomes a stable isotope again. I would also like the mention that the UK has only had one major incident with nuclear that had a significant affect on the locals, and that was The Windscale Fire, and the whole conception of Windscale came about after the USA backstabbed the allies and kept the nuclear weapons to themselves, so UK nuclear scientists needed to rush to make nuclear weapons. If I have made a mistake please make sure to leave a correction in the reply.

[@Matt_The_Hugenot]

During operations at Trawsfynydd the bioshield voids were routinely ventilated leading to aerial discharges of radioactive material. Similarly radioactive reactor coolant gas was vented periodically. _Source: Magnox Ltd_ Magnox reactors were designed to permit what was considered a minimal amount of radiation to escape in their cooling water. The designers recognised it was impossible to prevent any discharge so they set about keeping it as a safe as was reasonable.

Hi pal, I’ll grant the video isn’t perfect. I will try my best in the future as always to be accurate, but there’s also a creative element to this.

Hi Jay, Firstly kudos on your fabulous video. I am in Australia and had no idea that Wales had it's own Nuclear plants. Your stunning videography is unmatched. I've added your video to my curated list of all things "Atomic Nuclear" so others may enjoy it as much as I did. 5 STARS!

[@dorsetdumpling5387]

Some beautiful photography, but oh dear, the narrative is typical anti-nuclear sensationalism full of ‘if’s, ‘concerns’, ‘possible’s, ‘risk’s etc etc. You’re happy to cite a study that claimed that cancer rates were 15x higher downwind of the site and then have to grudgingly admit that the study was flawed and based on anecdotal evidence. I lived the first 30 odd years of my life at Trawsfynydd, much of that time was spent on and around the shores of the lake, fishing for trout with my dad. The trout we caught would be taken home and eaten without any qualms. My father worked at the Health Physics lab situated about a mile from the station where they had a regular testing regime of samples of fish netted from the lake, lake and rain water, lake mud deposits, milk from local farms, moss and vegetation, and airborne dust. Their methods were sensitive enough to detect that an atmospheric nuclear bomb test had been conducted at a time when the nuclear superpowers had agreed not to conduct such testing - China later admitted that it had been one of theirs. You could also have usefully mentioned the massive positive impact that the station had on the local community. In an area desperately short of work since the demise of the slate industry, the station provided some 800 relatively well paid jobs, now sorely missed.

Extremely good video. I used to drive past Trawsfynydd very regularly on my way to Harlech. That area always had a mystique about it after Chernobyl disaster in the 90s.

[@derekp2674]

Lovely video footage but the Trawsfynydd Magnox Station was not the UK's only inland nuclear reactor. I think it was the only one that used a lake as its environmental heat sink. Aside of all the research reactors around the UK, the BNFL Magnox Station at Chapelcross in Scotland was another example of an inland Magnox Station. But like its sister station at Calder Hall, it used cooling towers.

[@nigels.6051]

"Working head of water being around 630ft" - this had me a bit confused, with the lake having a depth of 4 meters on average. The 630ft refers to the height of the water relative to the Maentrog Hydro-Electric power station, which is down almost at sea level on the Dwyryd Esturary. This power station, opened in 1928, is still operating, the only power station now operated by Magnox! It produces 30MW, around 60 GWh of electricity annually, enough for 12,000 homes.

[@kellyjane2662]

Wow. My sister and I swam in that lake regularly during the early 80's on camping trips. All good healthwise! It's a special place to me.

[@radiosnail]

I thought it was a nice touch that Sir Basil Spence designed the buildings. Definately pro nuclear here. I do believe it was too important to be left to privatised electricity companies though. As a result we have an ageing reactor fleet and are having to use foreign technology now.

Informative, I have been and taken photos but didn't realise some of the impact of the design. I live reasonably close to Hinkley in Somerset the site is immense the impact already on its surroundings but then we do all use power which has to come from renewables or nuclear. When will they realise the power of hydro in the Bristol Channel

[@Robin-Smith]

There are many errors in this piece. My apologies for pointing this out, but you could correct them if you feel it will be useful. Hinkley C is 1.6GW per reactor, not 3.2. The later AGR's have no containment either and certainly do not have a concrete one. Only Sizewell B does and this is an American PWR design. What is the does rate of all the radioactivity events you speak of? You cannot say much about it until you have these numbers. It will only be useful for propaganda. I have several geiger counters, one is a spectrum analyser. If you want to join me we can do a site survey and get some real numbers to tell people about. We can also compare these numbers relative to background radiation What do you say?

There were fields along the shores of lake Bala that have been too radioactive for grazing animals. This was found after the Chernobyl disaster and blamed on that. The locals know that it was from Trawsfynydd. These fields were only signed off a few years ago.

Fallout from Chernobyl did contaminate much of the UK, particularly affecting hill farms. Not much was made about that by the mainstream Media.

[@codybevan300]

I remember a University challenge question about the voiced dental fricative, known to English speakers as the as the th sound in father, it's pretty rare except in English and Welsh. The welsh alphabet has a 'd' and a 'dd' - 'd' is as you would expect (the 'd' in 'dad'), 'dd' is the 'th' in father

[@nigels.6051]

Not really a "th" sound, the tongue should be in a different place, and it is not really a 'dd'; that is only used because the old printing presses didn't have enough of the correct letter 'ð'. Now we have computers capable of all characters, we should be using ð in type as well as handwritten script, then people would understand that they were pronouncing it wrong!

[@soundseeker63]

Those drone shots are spectacular. Wales has some truly magnificent natural beauty, seen even better from the air. I've seen these buildings they are imposing and kind of scary looking, sobering to think they will have to survive into the 2080s when they were designed to last maybe 1/3 of that... I have questions about the radiation - If the lake is indeed contaminated and this has been tested and confirmed, then why are there no warnings and people still swimming in the lake, fishing, eating the fish etc? Nuclear leaks do indeed happen (take the Sellafield incident for example) but one would expect a response to mitigate the risks to the population which appear to be totally lacking here. So either it's not radioactive or there's been a huge coverup.... Which is it?

Yes, far more likely that the decayed and thus no longer radioactive contamination at the bottom of the lake will get buried under 100 meters of peat as the lake fills up under its new use as a carbon sink for the atmospheric CO2 contamination released by fossil fuel power due to insufficient use of nuclear power. That is what has always happened with lakes in Wales, most of the lakes left by the glaciers after the last ice age are already full of peat - our best CO2 store, much better than trees, which have very limited lives before their CO2 gets released.

[@aquilarossa5191]

It's kind of cool to me that Welsh is probably quite similar to the language of the iron age Britons. It's a very ancient lingo. Less than 10 words remain of that ancient language in modern English. Modern English is a hybrid mixture of languages brought to Britain by the various invaders and conquerors. Latin from the Romans. Germanic from the Angles, Saxons and Jutes who eventually formed Angleland, i.e., England. Norse from the Danes/Vikings who ruled England under King Cnut the Great and King Sven Forkbeard. French from the Normans after William the Bastard showed up in 1066ad. That makes me think that the Welsh are far more British than the English. Hehe. (I am biased, because my grandma was Welsh and my other grandma was Scots -- the rest is Italian, Irish. and English - UK raised, but NZ born).

It is said that your brain learns the sounds of the letters in the first 5 years of life, after that most people can never learn the true sounds. So if you are English, we do not expect you to ever get it right, however long you live here, while if you are Icelandic, no problem!

Samples taken safely. P.S. It's nice and convenient to say the decommissioning company has to clean up the mess. The government commissioned the site, so should bear the bulk of the responsibility. Magnox is government owned in a way, but it can plead poverty. It only has limited resources. The government as a whole has far more. Clean up will take generations. BTW. I see folk saying breeder reactors and the like are safe. Safer perhaps, but whenever a fission reaction occurs on a scale great enough to produce megawatts of energy, there will be fission byproducts. Many of them emit ionizing radiation and some have very long half lives. All of that waste needs to be stored. Maybe okay on 1000 mile wide deserted plains or steppe, but maybe not so safe on earthquake prone islands like Japan or NZ (hydroelectric is the way to go here in nuclear free NZ -- so much potential because it rains so bloody much -- about 55-60% of our total energy mix is hydro and geothermal -- that mix includes energy we use for cars like petrol, so it's not bad going).

Strangely, the small hydro power stations built in the area have produced more electricity than the Nuclear power station. The turbines are still spinning while decommissioning continues.

I don't think that is actually true. While it rains a lot in the area, the amount of hydroelectric potential is actually quite small. While Maentwrog is quite a big hydro plant, rated at 30MW, it only averages 10MW. Trawsfynedd, when operating, was 500MW, so the only way you could get close, would be to include the pumped storage, which doesn't really count, since it doesn't generate power, only stores it.

​@@robinwhitebeam4386 It is quite hard to find good data on hydro, since most of it is very small scale and often not separately categorised. There are a lot of hydro schemes in Wales, there is one just up the valley from me, but like most, it is measured in KW, not MW. We just don't have enough water, or enough height to create the power. I agree that nuclear is going to be the more expensive, but hydro doesn't provide enough, so can't replace nuclear, however much is spent on it. We don't have the water, or height that Norway or Iceland have. Wind is the cheap answer, far cheaper than hydro or nuclear. That is why in the past 12 months, wind has been our largest source of electricity, exceeding fossil fuels, while hydro is only at about 1.3% of our electricity with most of our potential hydro power already tapped! I don't see the need for nuclear, except that most of our wind turbines are easy targets for submarine attack, so would give us a problem in wartime, it is good to have some variety of sources.

[@nigels.6051]

@@pauln6803 Wind in the UK is reliable. Yes, we have periods of low wind, so we need some storage, but we don't need much storage for our electricity supply, just need enough wind turbines to produce enough electricity 98% of the time. Then storage is needed for the synthetic fuels produced when electricity supply is greater than demand, There will be periods of low wind when we don't make much synthetic fuel, and periods when we make a lot. Storing synthetic aviation fuel, and synthetic methane gas is easy. Amongst other things, the methane can be used to top up our electricity on very low wind days, replacing our current natural gas, which is mainly methane, There are other solutions, but nuclear is many times more expensive than wind!

It can impede rational decision-making and contribute to counter-productive behavior and policies. Radiophobia is primarily a social phenomenon as opposed to a purely psychological dynamic. The term is also used to describe the opposition to the use of nuclear technology (i.e. nuclear power) arising from concerns disproportionately greater than actual risks would merit."_

[@joinedupjon]

The was also quite a lot of sea fishing near the outfall of Wylfa and still is at the two outfalls of Heysham - it's just that fish grow quicker in warmer water. Steam turbine power stations all need to dump some heat into the environment when they're working - that includes nuclear and coal. The film maker seems to think there must have been a lot of radioisotopes coming out of the pipes like it was Wales version of Windscale or Dounreay but really it never was and there's a lot of scaremongering in this film tbh. It's quite an alarmingly ugly eyesore in an area of otherwise pretty countryside though - which makes you think about what it was possible to get past the planners in the 50's and 60's compared to today... They did get a noted landscape architect (Sylvia Crowe) in to beautify the immediate area around the station but there's no hiding the huge concrete blocks.

His statement is actually correct in this case, although the use of English is not great! The reactors actually produced far more than 250MW each, but that was thermal power. By the time it had gone through the turbines and been converted into electricity, there was 250 MW of electricity, which in power generation is referred to as 250 MWe, which tends to get read as "250 megawatt electric", even by the BBC.

Hmm, if you went to Mousehole and called it "Mouse hole", then it would be understandable, because it is spelt differently to how the locals pronounce it - "mowzel", but if you were making a video about it, of course you would be expected to get it correct. You could of course give it it's original name of Porthenys, which you can probably pronounce better than most English people, since it is in Cornish, with Cornish spelling. The problem with Trawsfynyð is not that it is spelt wrong, but that Welsh uses a different alphabet, the letters have different sounds to English, with different rules for pronouncing them, so the English can't read it correctly. If we actually used the correct character for the last letter then people might realise that they can't read it, but instead we use 'dd' for ease of typing, then the English pronounce it as a 'd' instead of 'ð'! The Icelanders can pronounce it fine, they actually use 'ð' in their language, although like in Welsh, they use 'll' instead of 'ɬ', which was used in old Welsh, before the arrival of the English printing press with no 'ɬ' characters.

You're forgetting or ignoring the word "relatively". Obviously it's not cleaner than some renewables, but compared to burning coal etc it's massively cleaner. "Cheap" depends on who's building it but it's always cheaper than the current multi trillion pound cost of pollution from coal and other fossil fuels. Even including Chernobyl and Fukushima. By miles. One word can be important, e.g. the difference you're not wrong and, y'know, you're wrong.

[@codybevan300]

Please don't talk about the 'legacy' of places you can't say properly, or you're gonna look silly. It' not hard - Welsh has perhaps the most consistent phonology of any language, If you're not sure how it's pronounced: look up Welsh phonology and that's pretty much it (until you get to mutations). Which is [why it's 'Trawsfynydd' and not 'Trawsmynydd'] is a harder question. If you spent 50 hours making this video, an hour or diving into welsh pronunciation wouldn't hurt and could be fun and informative.

[@nigels.6051]

I've never heard it called Trawsmynydd. The normal spelling in Welsh is Drawsfynydd, and in English it is always Trawsfynydd, both pronounced as spelt, so if he had asked a true local, the answer may have been Drawsfynedd, which would have been wrong for his English language video!

No doubt in my mind that nuclear pollution in the enviroment is the real reason why so many people get cancer in the present day. They try to blame smoking.
