(1) J W COOK LETTER TO R L TEDESCO, SERIAL 10764, DATED JANUARY 12, 1981 (2) R L TEDESCO LETTER TO J W COOK DATED NOVEMBER 20, 1980 (3) J W COOK LETTER TO 11 R DENTON, SERIAL 14538, DATED OCTOBER 16, 1981 (4) J W COOK LETTER TO H R DENTON, SERIAL 14893, DATED NOVEMBER 30, 1981 Enclosed herewith are three copies of the latest revisions of the piping design package containing information for the Midland Unit 2 decay heat removal and core flooding systems. This is Revision 7 of the material being used for the Staff's independent confirmatory piping analysis performed by the Energy Technology Engineering Center (ETEC).
ETEC has additionally requested load histogram information to aid their analysis effort.
The enclosed histograms represent the thermal transients for the core flood lines as of May 1979. Some of the transients have been modified slightly since these histograms were prepared; therefore, there may be differences between the previously submitted Cescriptions and the histograms. The information which was previously 1.rovided governs in all cases. The histograms are not usually revised each L me the piping analysis 4
is updated. They are to be used only as gu delines.
Subsequent drawing updates will be issued o.1 a quarterly basis.
If there are any questions, please advise us.
