'NUCLEAR OPERATING CORPORATION Britt T. McKinney Site Vice President NOV 2 12003 WO 03-0064 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555
Reference:
Letter WO 03-0049, dated August 8, 2003, from Britt T. McKinney, WCNOC, to USNRC
Subject:
Docket No. 50-482:
Supplement to Response to NRC Bulletin 2003-01, "Potential Impact of Debris Blockage on Emergency Sump Recirculation at Pressurized-Water Reactors" Gentlemen:
This letter transmits a change in a Wolf Creek Nuclear Operating Corporation (WCNOC) regulatory commitment contained in the Reference.
This supplement is being submitted in accordance with guidance provided by industry document NEI 99-04, "Guidelines for Managing NRC Commitment Changes," as endorsed in Regulatory Issue Summary 00-017, "Managing Regulatory Commitments Made by Power Reactor Licensees to the NRC Staff."
The Reference contained a commitment to conduct an inspection to confirm that there are no adverse gaps or breaches in the sump screens.
This commitment also contained the inspection acceptance criteria of no larger than 1/8 inch for the inner screen and no larger than 1/2 inch for the middle screen.
WCNOC is not changing the portion of the commitment related to conducting the inspection, but has modified the inspection acceptance criteria by adding a tolerance to each criterion associated with breaches in the sump screens. Prior to plant restart following the fall, 2003 refueling outage, WCNOC will perform an inspection to verify that there are no gaps around the sump screens larger than 1/8 inch for the inner screen or larger than 1/2 inch for the middle screen or no breaches in the sump screens larger than 3/16 inch square for the inner screen or larger than 5/8 inch square for the middle screen. Deficiencies identified during work activities, including inspection activities identified above, are entered into the plant work controls and corrective action programs which provide the mechanisms to report and resolve any identified deficiency.
