Docket No. 50-289 JAN 2 81972 Metropolitan Edison Company ATTN:
Mr. John G. Miller Vice President P. O. Box 542 Reading, Pennsylvania Gentlemen:
As you know, an event occurred at a foreign pressurized water power reactor in which an unusual corrosion mechanism occurred when pro-longed leakage of borated reactor coolant onto the reactor vessel head was undetected. Subsequent tests have indicated that this cor-rosion potential might exist under certain conditions when borated fluid has prolonged contact with carbon steel.
To preclude additional experiences of this type, an appropriate program of inservice inspection should be implemented to detect such ef fects at an early stage. The ASME Code Committee for Inservice Inspection is considering revision of the ASME Code for Inservice Inspection of Nuclear Reactors. However, as an interim measure, we believe that the inspection program described in the enclosure should be incorporated into your inservice inspection program.
Please sdvise us within 30 days concerning your adoption of the provisions of the enclosure.
Sincerely,
Uriginal Sir,::ed By R. C. DeYoung R. C. DeYoung, Assistant Director for Pressurized Water Renctors Division of kenetor Licensing
