Subject:

Abnormal Occurrence 74-12: Leak in weld on Cb.arging Pumps discharge filter vent valve PIP ing Ginna Station - Docket #50-244

Dear Mr. O'Reilly:

{

This is to confirm my phone call on July 1, 1974 to Mr. John Hannon to report Abnormal Occurrence 74-12 at Ginna Station. ,

On Saturday, June 29, 1974 the Auxiliary Operator noticed a vapor in the charging pump room. Further investigation found the vapor to be coming from a leak in the weld that connects the 3/4" vent valve to the 3/4" nipple on the charging pump discharge half of the charging pumps discharge filter.

1 The PORC met and recccmended that the plant be brought to a cold shutdown  !

condition to replace the valve. The unit was taken off the line at 1330 '

on June 29, 1974. Repairs were completed at 0330 on June 30, 1974 and the '

unit returned to service at 0430 on July 1,1974.

Very truly yours,
