Abnormal Occurrence 74-12:

Leak in weld on Cb.arging Pumps discharge filter vent valve PI ing P

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, C
