Yesterday, I noted that a top physicist says:
What [the Japanese] are doing is basically using squirt guns against a raging forest fire.
He says the Japanese should instead use the Chernobyl style approach of entombing the reactors in boric acid, sand and concrete.
Today, nuclear expert Robert Alvarez - a senior U.S. Department of Energy official during the Clinton administration - pointed out to Kyodo News that dumping seawater on the reactors might actually further damage them:
When combined with the high heat at the reactor site, the seawater currently being poured on the facilities could destroy their cooling pumps or even corrode the containment vessels holding the plant's nuclear fuel, increasing the difficulty of containing the radioactive material.
