M. W. Hodges, Director, DE A. C. Thadani, Director DSSA C. E. Rossi, Director, DRIL B. A. Boger, Director, DRCH F. J. Congel, Director, DRSS FROM:
Steven A. Varga, Director Division of Reactor Projects - I/II Office of Nuclear Reactor Regulation
SUBJECT:
STATUS OF RESTART ISSUES ASSIGNED TO NRR FOR RESOLUTION, BRUNSWICK STEAM ELECTRIC PLANT, UNIT 1 Enclosed is a proposed memorandum to Region 11 indicating the completion of those technical issues related to the restart of the Brunswick Steam Electric.
Plant, Unit 1 (Brunswici.), that were assigned to NRR for resolution or assistance. We believe that all technical issues have been satisfactorily I
addressed and know of no open issues assigned to NRR that should delay a' t
restart recommendation to the Region II Administrator by the Restart Panel.
The licensee is progressing towards a Unit I restart during the week of January 24, 1994.
Region !! has scheduled a restart status and review meeting with the licensee on January 19, 1994.
In order to support this restart meeting, I request that all Division Directors inform Gus C. Lainas, Assistant Director for Region 11 Reactors, or Patrick Milano, Brunswick Project Manager, of any outstanding issues involving Brunswick that that could impact the unit restart.
This information should be forwarded as soon as possible, but no later than noon Tuesday, January 18, 1994.

K. B. Altman
SUBJECT:
Unit 1 Startup and Power Ascension Contingencies Attached is a listing of proble.ms which have occurred during previous startups along with planned actions to prevent or reduce the probability of recurrence during the upcoming Unit 1 startup. The list was developed with input from Maintenance, Operations, and Technical Support personnel, by a review of BNP Ucensee Event Reports from 1991, 1992, and 1993, and lessons learned from the recent Unit 2 startup.
Please ensure the open items on the attach 9d list are accomplished prior to the Unit 1 startup, unless they are scheduled to be completed during the actual startup and power ascension. Status updates should be provided to me at extension 2802 or pager 754-0429. A written update on the list will be issued periodically at the outag.# meetings, b %% -

6 BRUNSWICK UNIT 1 STARTUP READINESS ASSESSMENT Debrief Notes 8/27/93 Report No. B-SP-93-06 An assessment of the Brunswick Nuclear Plant Unit I readiness for startup was performed on August 20-27,1993, and was debriefed on August 27,1993.
Purpose:
The Nuclear Assessment Department conducted an assessment of the readiness of the Brunswick Nuclear Plant (BNP) Unit I to conduct a safe startup and maintain sustained, reliable plant operation.
Results:
Overall Amnessment Summarv The progress of the BNP Unit 1 outage, coupled with the Unit 2 proven line management self assessment of readiness for restart (PN 31 process), supports safe startup of Unit 1.
The uncertainties associated with the core crack will require additional investigation and resolution.
A strong management team and good performance by Operations were noted.
Improvement in work scoping, scheduling, and coordination were noted compared to the February 1993 Unit 2 Startup Assessment.
Assumptions:
1.
'Ihat the plant completes the Integrated Startup Plan (ISP) submitted to the NRC on November 30,1992 (BNP Ltr 309-13510, Ser BSEP 92-0046, of November 30,1992).
2.
That the commitments to the NRC contained in the July 23,1992, CP&L 1mprovement Program (CP&L Ltr NLS 92-160 of July 23,1992) are met.
3.
That the PN 31 (Line Management Self Assessment of Readiness for Restart of BNP Unit 1) is satisfactorily completed.
4.
That the Unit I restart targets, as set forth by CP&L in the NRC June 9,1993, presentation to the NRC regarding " focus" syr'em work request / job orders, corrective maintenance, operator work arounds, temporary modifications, Control Room annunciators, permanent caution tags, and short-term structural integrity items, are met.

5.
'those elements of the Unit 1 Startup and Power Ascension Performance i
Objectives and Management Plan needed for initial rod pull and power ascension I
are satisfactorily completed.
Potential Issue; Managesnent of contracton involved in refuel floor activiiles must be strengthened.
Unit I refuel floor activides have resulted in several events or near misses in July and August 1993.
1 e
Itemt for Mannerment Consideration:
1.
Continued improvement in work control and scheduling is needed to optimize Safe Shutdown Risk Management.
2.
Ownership of the design by Nuclear Engineering Department (NED) discipline managers is an important element of configuation management.
N E D is allowing design decisions to be made by non-design personnel.
3.
As a result of fuel debris, GE has recommended that BNP consider " Gentle" fuel cycles to further minimize the potential for fuel leaks. BNP management is encoumged to reach a decision regarding this recommendation prior to leginning Cycle 9.
