Dear Mr. Mroczka:
EJordan
SUBJECT:
MILLSTONE UNIT 3 INITIAL TEST PROGRAM (TAC NO. 60380)
Section 2.C(10) of Facility Operating License NPF-49, for Millstone Unit 3, requires that, "Any changes to the Initial Test Program described in Section 14 of the FSAR made in accordance with the provisions of 10 CFR 50.59 shall be reported in accordance with 50.59(b) within one month of such change." The enclosure, herein, provides a list of the submittals made in accordance with Section 2.C(10) of Facility Operating License NPF-49. With regard to the revised loss of offsite power (LOOP) test described in the licensee's May 2, 1986 letter, the licensee did not provide sufficient justification to support the changes made to the LOOP test.
The staff discussed this issue with the licensee by telecons on August 13, 1987 and September 26, 1988, and during a meeting at the Millstone Unit 3 site on February 22, 1989 attended by the NRC resident inspectors. The licensee presented additional documentation and supporting information during the february 22, 1989 meeting. This additional documentation and information was submitted to the NRC by letter dated April 6,1989.
The staff has reviewed the contents of the April 6, 1989 submittal and concluded that the revised LOOP test conducted by the licensee et Millstone 3 and supported by the additional testing and analysis described in the April 6,1989 submittal did adequately demonstrate the capability of Millstone Unit 3 to recover from a loss of offsite power event.
We have completed our review of the submittals identified in the enclosure and conclude that the changes to the Initial Test Program are acceptable, and that you have satisfied the requirements of Section 2.C(10) of Facility Operating License NPF-49 and the requirements of 10 CFR 50.59 with regard to your
.nitial Test Program for Millstone Unit 3.
