Dear Commissioner Carr,
Can you explain why your suoordinates are calling "the sinter-cake found in the damaged Three Mile Island-2 j'
reactor previously molten material"?
(See the cover of Nuclear Technology, Volume 87, Au6ust 1989.)
Don't nuclear engineers, officers graduated from naval reactor school,' and licensed reactor operators 6et tau fuel pellets for power plants are sintered to 95% ght that the UO density at t
p
. temperatures below 1800 C ?
t May I suggest that the Eovernment reprint Jack Belle's-i book on " Uranium Dioxide".
Then, perhaps, the next Seneration of scientists will be able to read how UO -can be sintered in steam 2
at temperatures as-low as 1200 C. They won' t waste tax dollars lookin6 at the effects of water-quenched sinter-cake upon lower pressure vessel steels.
Sincerely.
Wals ton Chubb:
