🆕@Cambridge_Uni will help train industry-ready #nuclear scientists as part of 2 UK Research and Innovation (UKRI) Doctoral Focal Awards in Nuclear Skills https://t.co/nEJnkw1weQ At Cambridge, 26 #PhD studentships expected as part of the two progs @cebcambridge @DeptofPhysics

Close one!

Anglo-Irish scientists seem quite impactful too: Stokes, Hamilton, Boyle

My new favourite published graph. Compares correlations used by the Soviets and Americans for radiative transfer calculations. From 'Fast, accurate numerical evaluation of incomplete Planck integrals'.

I was not expecting this metaphor

After much effort, I'm happy to finally present the Universal Reactor Memorandum of Understanding (MOU). This MOU is hereby issued between all current and future reactor companies and all current and future power customers. Congrats to all!

Probably still a few bugs to sort out...

I have been having fun with adding new visualisation techniques to our Monte Carlo code. Here's a plot of the Advanced Test Reactor

I've been cultivating a nuclear playlist for just such an occasion. Not sure how many of these would fit in a rave, admittedly... https://t.co/XgA93JqVc8

"Good morning Nicholas! New demographic you inexplicably have to pay for just dropped."

I think Edward Teller has been reincarnated. "Nuclear Explosions for Large Scale Carbon Sequestration":

Definitely true in nuclear engineering. Each year we get loads of talented applicants and getting funding is a coin toss. https://t.co/qQmdjco5AZ

Meanwhile the French navy has an entire class of ships named after the Marquis of Lafayette, who helped the American rebels commit treason against Britain.

Of course there are plenty of reasons to support Rolls-Royce SMR, just not because they are experienced at building civil PWRs.

Asserting that submarine reactors ~ civil reactors is a remarkably common handwave. Interestingly it gets deployed either to support RR SMR or to suggest that we don't build advanced reactors because we're too fond of military technology.

This is how Wallace and Gromit: The Wrong Trousers starts

Are there dose estimates for this?

Anyone know anything to support or disprove this? I'm also curious about exactly why the reportedly greater instability at low power. My guess is because there is simply more water, rather than the water/steam mix at nominal power.

For a fresh core, only U235 is fissile. Voiding will reduce neutron absorption, but the Maxwellian will also be shifted higher, coinciding with a lower fission xs. For a burned core, there is some Pu239. Shifting the Maxwellian higher, but dragging it towards a fission resonance.

I keep reading that RBMK's void coefficient became more positive with burn-up, but can't find a convincing explanation. My guess is that it's because the graphite is hotter than the water/steam at power.
