Nuclear Thread - 4

[Arun_S]

I have seen how Indian nuclear reactor eqpt is tested for earth quake resilience, on a massive shake table. That was more than 20 years ago, and I think things have only become more better.



Few observations on why Indian reactor are different and more resilient compared to the type of failures seen in Japan:

1. After earthquake Japanese reactors were shut down. But they are light water cooled design, that have far different meltdown failure risk compared to Heavy Water cooled Indian PHWR.
2. Almost all reactors are natural Uranium fed core, thus core size is big, and cooling is much easier.
3. Most Japan failures are due to residual heat when reactor is shutdown. Their enriched core design result in high flux even when spent fuel is taken out of reactor. So the heat flux is also high.
4. Only FBR and Tarapur use higher enrichment fissile fuel.
5. Kalapakkam did pretty well against last Indian Ocean Tsunami
6. AHWR design is based on learning from PHWR, with various levels of emergency protection, moving more towed passive protection features as against active protection that depend on pumps, generators etc.

Now on another topic: Public awareness and preparedness.



Indian population center are at risk of Jihadi Delivered Munition(JDM), and civil defense and people at large MUST stock up on Iodine salts to protect against fallout danger that comes with nuclear explosion. Its cheap, and one must be prepared rather be sorry. Next 2 years I am told are crucial, (when JDM can hit India).



Every family must store water and food to tide over 2 weeks, the period that is required to let high radioactivity, low half life actinides to subside, when going outdoor will be very dangerous.
