CLOSURE OF TAC REGARDING GENERIC IMPLICATION OF THE PART-LENGTH CONTROL ROD DRIVE MECHANISM HOUSING LEAK AT PRAIRIE ISLAND UNIT 2 - JOSEPH M. FARLEY NUCLEAR PLANT, UNITS 1 AND 2 (TAC NOS. MA1380 AND MA1381)
Dear Mr. Morey:
By the enclosed letters dated August 11 and December 23,1998, the NRC has responded to Westinghouse Owners Group (WOG) positions regarding corrective actions to address generic aspects of the part-length control rod drive mechanism housing issue that originated as a result of the leak at Prairie Island, Unit 2, on January 23,1998. The WOG program is a voluntary industry initiative to address this issue.
By letter dated March 30,1998, you discussed your participation in the WOG initiative and the activities at Farley Nuclear Plant resulting from that initiative. The NRC staff's review of these letters and results was performed under TAC numbers MA1380 and MA1381.
As discussed in the December 23,1998, letter, the NRC staff has concluded that, given the marginal increase in risk and the small number of welds with potentially reduced safety margins, the actions taken under the industry initiative are acceptable for protecting public health and safety. Accordingly, our review under TAC numbers MA1280 and MA1381 is considered complete.
If you have questions regarding this letter, contact me by phone at (301) 415-2426 or by electronic mail at jiz@nrc. gov.
Sincerely, original signed by:
Jacob 1. Zimmerman, Project Manager Project Directorate 11-2 Division of Reactor Projects - 1/11 O+P of Nuclear Reactor Regulation Docket Nos. 50-348 and 50-364 1
