SUBJECT:
R.E. Ginna Nuclear Power Plant Docket No. 50-244 Inspection and Mitigation of Alloy 82/182 Pressurizer Butt Welds In October of 2006, while performing inspections of its pressurizer Alloy 82/182 butt welds in accordance with MRP-139, a PWR licensee discovered several circumferential indications in its pressurizer surge, safety and relief nozzles. Because of the potential importance of this issue, I am submitting this letter to notify you of R.E. Ginna Nuclear Power Plant, LLC's actions taken or planned for inspecting or mitigating Alloy 600/82/182 butt welds on pressurizer spray, surge and relief lines.
The pressurizer at R.E. Ginna Nuclear Power Plant does not have Alloy 600/82/182 butt welds. Future inspections of pressurizer butt welds will be performed in accordance with the R.E. Ginna Inservice Inspection Program which meets the industry guidance of MRP-139 for our weld material.
Should you have questions regarding this matter, please contact Mr. Robert Randall at (585) 771-3734, or robert.randall@constellation.com.
Very truly yours, Mary G. Korsnick cc:
