January 13,1996 Mr. Bruce D. Kenyon President and Chief Executive Officer Northeast Nuclear Energy Company c/o Terry Harpster P. O. Box 128 Waterford, Connecticut 06385-0128-

)

Dear Mr. Kenyon:

This letter documents the meeting held between the NRC and Northeast Nuclear Energy Company on December 17,1996 to discuss the recovery and restart plans for the three Millstone Units. At that meeting, you presented slides (Attachment 1) which outline your plans leading to the restart of each of the units. You also proposed the concurrent recovery of all of the units versus the restarting of a single unit that was previously discussed with your staff. We noted, with reservation, your projection of Millstone Unit I as the lead plant for readiness to restart, with Unit 3 and Unit 2 following in close succession. You acknowledged the potential impact on NRC resources in implementing our regulatory oversight activities necessary for restart with all of the units approaching readiness for restart simultaneously, and conceded arrangements to accommodate the necessary oversight activities.

We expressed a need for a consolidated listing of open issues that NNECO proposes to either complete prior to restart or to defer for each unit. A discussion ensued regarding the form the lists would take and the actual content of the listings. You indicated that NNECO would propose an approach to address this issue.' However, we note the Operational Readiness Plan Punchlist provided in your letter, dated August 13,1996 (B15839) served as a useful initial document for Unit 3. We expect similar documents for Units 1 and 2 as well as update and status information for significant changes.

" g found the meeting to be useful as a first step in open communications between the NRC, M4fCO and the public. We propose that a continuation of the meeting process be scheduled on a timenthly (every two months) periodicity for the next several months to ensure adequate coordination of our combined efforts.

Your continued cooperation is appreciated.

Sincerely, ORIGINAL SIGNED BY:

Participated telephonically On July 16,1996, the Millstone Oversight team met to discuss the final details of the MC 0350 Restart Action Plan. The decision was made to remove the plant specific information for Units I and 2 from the current plan.

This information will be provided later as the units near return to service. The MOT will focus on Unit 3 restart.

During the meeting, specific line items in the significant issues list for Millstone Unit 3 were discussed, responsibility assigned, and new additions were made. For those areas assigned to NRR, the region will provide more definitive descriptions of the scope of support needed.

The tables in the draft Restart Plan will be revised to change the column labelled 'ACR NO,' to " Reference" because of the generic content of the list.

The current plan is to not do detailed reviews of the configuration management plan submitted by the licensee, but to ult mately opt for an independent Design Verification Program to be initiated by the licensee. This will i

provide an independent, in-depth examination of the licensee's process that will provide requisite assurance. This proposal will be presented to senior management for approval.

The decision was made to add all MC 0350 items to the Restart Plan and 'NA* those items that are not applicable. This will show a conscious decision to climinate an item.

The licensee / NRC meeting to 1 e held on July 24,1996, will deal with the licensee's restart plan for Unit 3, their restari punchlist, and the key performance indicators. There will be a public mating on August 1,1996 to discuss the NRC restart plan.

J. Durr will develop a time line for major milestone impacting MC 0350.

The next scheduled MOT meeting will be held at 1:30 p.m. on July 23,1996.

20. Chemistry Index INPO Definition: The chemistry index compares the concentration of selected impurities to the limiting value for those impurities. Each impurity value is divided by the limiting value for the impu/ /, and the sum of these ratios is normalized to 1.0. 'Ihe limiting values are the " achievable values" defined by intern ional industry-acceptext values. Due to design differences, this indicator is calculated differently for BWR's and PWR's. 'Ihe purpose of this indicator is to evaluate and trend progress in improving chemistry control, by monitoring impurities that are the most likely cause of hiviation of i

BWR reactor materials and PWR steam gc.wrators.

23. Rework dU Definitions: AWO = Automated Work Order.

Monthly Rework = Number of closed rework AWO's during the month divided by the total number of Corrective Maintenance (CM) and Other (OT) AWO's during the month.

Rework is that work which results after Operations identifies a failed retest. For Seabrook, rework is defined in procedure MA 3.1, ' Work Requests", which evaluates equipment, failures, time since failure and work completion deficiencies.

The number of Rework AWO's is listed above the total number of closed CM and OT AWO's for the month.

26. Trends in Nature and Number of Notices of Violation NU Definition: Notices of Violations are those violations that have been identified in a NRC inspection and Northeast Utilities has been notifial.

Unit Date I n cl Description CY Jan i1,1993 IV Ucensee's measures to correct conditions adverse to quality were inadequate as evidenced when a motor c.L" valve was :W to thrust in excess of the masimum allowable. (NCR 92-100)

CY Jan 26,1993 IV The qualifications of 2 solenoid valves were not established in the Ha& tam Neck Environmental Qualification Master List and there was so documentation available to demonstrate the valves

qualifications.

CY Jan 26,1993 V

A Design Change Notice specified that a jacketed ground cable be connected to the base of the electncal p :id.ees. The cable was found to be connected to the duct bank ground grid instead.

CY Feb 3,1993 IV Qualified Technical Support Managers did not receive Ewigaay Action level training for a penod of 18 im.rfos. The E-mgy Action Plan requires training annually. (1 year i 3 months)

CY May 4,1993 IV Two power operated ASME code class 2, category B valves were neither stroke time tested nor had specific wntten relief been granted by the NRC.

SB Apr.1993 IV A safety c*aluation was not written prior to changing the design basis tor indo described in the Updatal Final Safety Analysis Rout.

MPI Feb 1,1993 IV Ucensee 6 d not update the Final Safety Analysis Report within the allowed time following the congletion ofineressmg the spent fuel pool capacity.

Ucensee did not perform an audit of the pre i ms for training, retraining, qualification and performance of the operation staff as required by MP1 Feb 24,1993 IV s

Technical Specifications and the NU Quality Assurance Program.

MPI Apr 30,1993 IV Ucensee did not develop effective corrective actions to preclude the recurrence of failures of safety-related auxiliarv electrical contacts

(

MP2 Jan i1,1993 IV The implementation plan for a PDCR was not translated correctly into the work order. CcaaWly,2 vital inverters and associated static switches were removed from service simultaneously, resulting in a loss of normal power to the plant.

MP2 Feb 1,1993 IV Ucensee had not identified a reactor building closed cooling water valve as having similar control logic to a similar valve which was the subject of a Ucensee Event Report.

MP2 Apr. 6,1993 IV Revised valve position markings caused the HPSI system to be rendered inoperable and the west 480 volt switchgear room coolers were retumed to service follow'sg a failed hydrostatic retest without being tagged or nonconformance report written.

MP2 Apr 30,1993 IV On three occasions, steps in the RPS Turbine loss of Imd Test were not performed as required.

MP2 Apr 30,1993 IV The licensee did not report an unplanned automatic initiation of the RPS system until 17 days after the event.

MP3 Feb 1,1993 IV Bypass jumpers were not initiated for scaffolding installed greater than 90 days, PORC review of bypassjumpers installed over three months or expected removal date was exceeded was not being performed, and the quarterly sumtrary was not being submitted.

Corp.

May 4,1993 11 Northeast Utilities was cited for subjecting an employee to harassment, intimidation and discrimination for raising a potentially significant (1) generic safety issue.

Corp.

May 4,1993 Ill Northeast Utilities was cited concerning the NRC's Part 21 regulations governing the timely evaluation and reporting of significant safety (1) hazards concems.
