Dear Mr. Collins:

r On October 19, 1982 a problem with the design of the maintenance hatch shield door seal system was reported to your office as Potentfally Reportable Deficiency #92. This letter is to inform you that after further eraluation, this specific problem is not considered to be repor::abiq purslant to the requirements of 10CFR50.55(e) for the following reas7n:

1 As originally designed and soproved for constructiot, the Maintenance Hatch Shield Door (MHSD) Seal System was a single non-qualified (i.e., non-safety-related) air supply system to maintain the MHSD itflatable seals. Prior to delivery of the non-safety-related equipment, the question of acceptability of the original design was raised in Construction Engineering Information Request IC-244. It was concluded that the apprcred design was not 9dequate and that the system would have to be upgraded to a safety -related design. As a result, a design change was initiated to revise the system to a safety-related design. i The NRC was notified o f the condition because a non-safety-ralated seal system control panel was received on site. This condition has ben determined to be not reportable because the design change was initiated prior ^to receipt of the panel and it was not installed. The non-safety-related systen did not represent the final design. All equipment instc11ations will be based on the new safety-related design.

Very truly yours,

[ 7 8212030048 821122 .
