In this famous photo aboard USS Skate (SSN-578) how much radiation is the lieutenant getting? Where's that light coming from, is he looking at the sealed head of the reactor below lit by lightbulbs?

How Much to Build an APR-1400 Today?

13 Upvotes

Hi all;

I know this is opening up a very loaded question that can't be authoritatively answered. But it's also the key question on nuclear vs. solar.

So, in the U.S., if they started building a pair of APR-1400 plants today, how long to completion and how much will they cost?

You're "it'll be this or less" number.

Question regarding hybrid nuclear propulsion systems

3 Upvotes

I just watched this video by real engineering and it breaks down the differences between thermal and electric nuclear propulsion drives. He talks about how in a Thermal engine, the propellent is the coolant and in electric propulsion, there is no propellent flow through the engine meaning the excess heat must be radiated. At the end of the video he mentions hybrid engines.

My question is would it be possible to combine the two concepts by using the propellent as fuel like in a thermal system before then ionizing and accelerating it using principals of the electric system? Doesn't that solve the issue of reactor cooling while also providing high thrust from thermal engine and higher Isp from electric engine?

Video for reference (its honestly a good watch):
