Molten Salt Reactor Safety Assessment - Dr. David Holcomb @ TEAC12

Dr. David Holcomb, the Molten Salt Reactor Technology Lead presents 2024 edition of Molten Salt Reactor Safety Assessment.
Safety Adequacy Assessment is Central to Nuclear Power Plant Licensing.l Atomic Energy Act of 1954 as amended sets out the safety requirements for commercial nuclear power plants (NPPs): Agree to observe such safety standards to protect health and to minimize danger to life or property as the Commission may by rule establish...
- Nuclear Regulatory Commission (NRC) provides the rules to implement the legal requirements
- Reasonable assurance of adequate protection is the guiding principle for the rules.
Efficient and Effective Safety Adequacy Demonstration is Key to Widespread Molten Salt Reactor Deployment. Molten salt fuel and coolant provide desirable performance and safety characteristics
Characteristics can be leveraged to decrease cost and time necessary to develop reasonable confidence of adequate safety:
• Low pressure, low-chemical potential energy, partial radionuclide retention, negative reactivity feedback, effective natural circulation heat transfer
• Acceptable safety continues to depend on fundamentals: Quality assurance. Good design, proper construction, adequate maintenance.
Substantial technical differences from other reactor classes necessitate:
- Distinctive systems, structures, and components (SSCs) performance information
- Customized tools and analysis methods

I'm running a Patreon campaign to help cover time/effort costs associated with video capture and edit. www.patreon.com/thorium ...any support is welcom. I do charge yearly so while signing up might be a hassle, it need not be a financial burden. Thanks for any help, -Gord

David is one of the bravest researchers in the national labs - working to keep technology alive

[@ThoriumEnergyAlliance]

Thanks for your work David!

If the FAA were run like the NRC we wouldn't have a single airplane flying.

[@Scientist538]

I always enjoy hearing from Dr. Holcomb.

[@toddmarshall7573]

When everyone in the chain is an avoider you're likely to avoid... i.e. do nothing. Nothing ever got done by doing nothing. Imagine if we had been using and refining Thorium MSRs for these last 50 years. Then someone comes in a proposes a LWR. They would be laughed off the planet.

[@chapter4travels]

So if we stick with the outdated LNT thresholds tritium will be an issue. If we update these regulations to real science, not so much. The NRC will fight tooth and nail to maintain antiquated regulations if it helps them destroy new nuclear.

[@philipwilkie3239]

Worse still such an admission would demonstrate the basis of much of their over-regulation of existing nuclear to have been utterly wrong.

[@FernandoWINSANTO]

On thresholds google : "DR John Gofman his life" According to Him threshold is an (1) electron hitting/crossing a living cell (1 hot particle in the lungs °...) . Keeping fission/activation products " in " ... what about environmental permits for radioactive substances activities and cumulative effects? Ultimately everything gets " out " starting with used fuel already a huge amount ... °DNA damage tracks

[@timothytaylor5867]

Doesn't have to be an issue if your fuel salt doesn't contain LiF or LiCl, even if the lithium salt is enriched to a very high Li-6 purity, Li-7 will still produce tritium.

[@salec7592]

tritium would be best stopped from leaking if it is captured in a chemical compound, for that you would need some kind of a sheath containing an reactant which has affinity to chemically bind hydrogen.

[@FernandoWINSANTO]

Done for candu reactors.

[@any1alive]

to be fair, the government doesnt want them, so if you make the laws strict then it costs too much todo it and the return is so low its bad, just like efficency, anything above 50%~ efficent the government can classify and hide it from the public when using patents .

[@FernandoWINSANTO]

Nuclear reactors efficiency is 33%

[@FernandoWINSANTO]

Censorship 95%.

[@FernandoWINSANTO]

Safety to workers, technicians does matter.

[@robertfarrimond3369]

And Hanford

[@peterbaxter8151]

The American aircraft manufacturing industry started building on “acceptable” safety. Ask Boeing just how well that’s going.

[@downstream0114]

What an executives consider acceptable and engineers are two different things.

[@konradcomrade4845]

look at Boeing B52 Crab Landing (sideways swivelling gear) Videos! Then You know what amazing things this company could do in the past; only few nerds now about it.

[@MatthewHolevinski]

David low-key talking mad cat sh*t for 25 minutes 😂
