“Seth material” search engine (Jane Roberts)

In Note 2 for the 936th session, I also described how the NRC had asked the operators of certain nuclear power plants to check for cracks in the vessel walls of their pressurized-water reactors, which are the kind installed at TMI. Now problems with corrosion are being announced. The reactor for Unit No. 1 at TMI is undamaged; it had been shut down for maintenance and refueling at the time of the accident to its twin, nearly three years ago, and a series of delays has kept it idle ever since. In February, again, company officials revealed the discovery of extensive corrosion in the bundles of small-diameter tubes in the two steam generators powered by Unit No. 1, which will delay any restarting of the unit for another six months to a year. The tubes circulate hot radioactive water from the reactor throughout the steam generators. Replacement of at least several thousand such tubes will cost millions of dollars; if engineers simply plug the damaged tubes, the reactor will operate well below capacity. (Steam generators at some other plants have a new problem: the accumulation of a corrosive sludge at their bases.)
