Office of Nuclear Reactor Regulation May 21,1985 Attn:
H. Denton, Director 5211-85-2095 U.S. Nuclear Regulatory Commission Washington, D.C. 20555
Dear Mr. Denton:
Three Mile Island Nuclear Station, Unit 1 (TMI-1)
Operating License No. DPR-50 Docket No. 50-289 Results of GPUN Management Review for Restart Ammendment 103 to the TMI-l Operating License requires in part that " prior to initial criticality (1) GPU Nuclear Corporation shall submit to NRC.... a summary of its management review." (See License Paragraph 2.C.(8).1).
The purpose of this letter is to satisfy this requirement by providing relevant background information and the latest Restart Readiness Review Committee Meeting results (held on May 9, 1985). A description of the TMI-l Prerequisite Program, previously provided by our letter of May 11, 1984, has been revised and is attached (Aapendix No. 1) for your information.
In addition we have included Appendix No. 2 which describes the scope of our various internal reviews.
The TMI-l Prerequisite Program was developed in March of 1983 so that GPUNC Hanagement could, at selected points within our restart program, review in a systematic and thorough fashion, TMI-l's readiness to proceed safely from milestone to milestone, culminating with TMI-l's return to full power operation.
This process, developed to certify internally TMI-l's readiness to restart safely, was established because:
- 1) Many major modifications have been made to plant systems over the last six years,
- 2) changes in the overall organization have taken place, bringing new personnel to GPUNC, 3) GPUNC management requirement to insure all Divisions participate in this review process and 4) GPUNC Management desire to reduce the action item backlog in several areas.
Several Management Readiness Review Meetings have been held over the last two years.
The following listing provides dates held and the Milestone (event) being reviewed by the GPUNC's Readiness Review Committee (RRC):
(1) Initial criticality refers to the first criticality following the steam generator repairs completed in 1984 and 1985.
