Three Mile Island Unic #2
Dear Vic:
Attached is a copy of the tenative standard on Iligh Efficiency Cas-Phase absorber co11s (AACC Designation SC-ST) that we discussed at the meeting in Philadelphia last month.
-k The CS-87 was prepared by a subcoccittee of which Mr. C. A. Durchsted and Mr. H. Gilbert vere menbers. The flat bed type or tray type of ec11 -
is si::.ilar in design and countruction to the cells being supplied on Three Mile Island Unit #2. The obvious descrepancy in their reco:ccended design and the units being supplied are the cell lengths. The CS-ST recorrended length is 30" where as the Three Mile Island design calls for 40" long cells.
MSA feels that the 40" long design nay cause possibio probica arcas in the AEC Licensing requirc::ents. The following problem areas cay occur:
1.
Substantial ec11 weight increase t.akes change-out problems.
Two can minitum will be required to re'=ovo.
2.
Lonner cells can create possible void areas in refilling.
3.
Lonner cell calls for longer perforated screens and, therefore, coro support areas and possible dead areas.
Again, may I point out that possible AEC-Licensing problems may occur and MSA recornends to adopt the 30" long design. Your co: cents on the above vill be appreciated, should you have any additional questions 3 please don't
, hesitate to call.
Sincerely,
~
