I strongly recommend people do not get their nuclear safety information from Dr. Eric here.
Perhaps he's a good doctor or whatever (has a lot of followers so that's good?) but he is unselective about which nuclear risks are or aren't capable of causing large-scale disasters.
If it doesn't stop, it will keep including nuclear safety issues, so we're going to see folks like Dr. Eric say each thing could cause a giant radiation disaster.
This is not helpful in understanding what the real risks are.
Please follow @CherylRofer who knows many of the world's experts with hands on experience with THESE SPECIFIC FACILITIES.
@jrmygrdn is great on these too; he asks technical experts the key questions he needs to understand, then interprets their answers in context for the public.
I watched Eric educate himself about nuclear plants in real time the day Zaporizhzhia was taken.
When he decided his main safety concern was spent fuel, a low-ranking concern for most of us nuclear folks about an OPERATING plant, the limits of learn-as-you-go became clear.
Can an epidemiologist provide cool-headed analysis of nuclear energy to benefit to the public?
Yes!
I work with a team from around the world, both in and out of industry, many self-taught, going night and day to gather information and process it.
This isn't what Eric's doing.
The specific trap Eric stumbled into is the classic "clog the toilet" strategy by organizations trying to eliminate nuclear energy.
They block waste storage while falsely claiming it's a health threat as managed.
THE BASICS: when fuel rods are done making energy in a reactor, plant staff remove them and put them in pools of water.
This is because the particles produced by the splitting of uranium ("fission products") are unstable and continue to undergo decay, and, thus, generate heat.
How much heat a fuel rod puts out depends on how much energy it produced in the reactor (called "burnup") and how long it has been since it left the reactor.
22 years is LONG ago. And RBMK (Chernobyl reactor type) has lower burnup than other reactor types, thus lower decay heat.
SOUTH KOREA ELECTIONS: EARLY EXIT POLLS SHOW TINY LEAD FOR PRO-NUCLEAR PARTY
Six yrs ago, SK had one of the most admired, and ambitious, nuclear energy programs in the world.
Rapid progress on domestic plants plus winning & starting to deliver in UAE.
Since then: devastation.
With the election of a resolutely antinuclear president, Korean reactor performance plunged, falling as low as 59% by 2018.
New president canceled the future fleet and attempted to stop the plants ALREADY under construction. Only defeat in his Citizens' Jury saved the projects.
Despite continuing success at Barakah in Abu Dhabi, no other countries bought Korean reactors, as SK President harshly attacked his own nuclear. After all, if Hyundai cars were banned for being "too dangerous" in Korea, how popular would they be overseas?
First: if seismic sensors at the plant were triggered (for example if shells or bombs are used) the reactors which are of very different design would shut down automatically.
Second: the main risk at the plant is that cooling does not get to the reactor cores over time.
The containment domes around the reactors are extremely strong.
They will not be affected by light arms or moderate fire from heavier arms.
The worry is in interruption of plant cooling procedures after the reactors shut down.
Ghana is tired of running short on generation, and is advancing from its existing nuclear research reactor program to a full commercial nuclear energy program.
Ghana can be the Sweden of Africa, blending existing hydro with new nuclear.
I visited Ghana's research reactor in October of last year.
It was cool but the real highlight of my trip was a conversation with Dr. Stephen Yamoah, director of Nuclear Power Ghana, who is quoted in the GhanaWeb article.
He had a clear vision and a plan. His team is executing.
Intriguingly, the Ghanaian nuclear program has attracted a proposal from SNC-Lavalin to build CANDUs, which if built would be the first CANDU exports since Qinshan in China twenty years ago.
It's surprised observers in Canada who thought the CANDU new build era was over.
