SUBJECT:
Peach Bottom Atomic Power Station, Unit 2 Release from 70% Power Plateau
-On June 28, 1989,Section V.A of the Shutdown Order issued March 31, 1987 suspending power operation with respect to Peach Bottom Atomic Power Station (PBAPS) was modified to permit operation of Unit 2 not to exceed 70 percent full power.
In accordance with the approved Restart Power Testing Program, Peach Bottom Atomic Power Station has accomplished the planned activities at the 70% power level and completed a comprehensive nanagement review on July 19, 1989 of station equipment, personnel performance and management processes through July 19, 1989.
As a result, the Management Oversight Team (MOT) concluded that the physical plant status, operational reliability, personnel performance, and management processes are adequate and Unit 2 is able to safely proceed towards 100%^ power in accordance with the approved Restart Powar Testing Program.
The PBAPS Restart Power Testing Program MOT met on July 12, 1989 after the transient testing period at the 70% power level was completed to review line management assessments of operations, maintenance, services (chemistry, health physics, radwaste),
technical support and security.
The MOT met again on July 19, 1989 to review steady state operation at nominal 70% power.
The MOT reviewed plant operations and open items from the previous meeting.
In addition, at both meetings the MOT reviewed Nuclear Quality Assurance evaluations, independent industry observer observations and MOT member observations which confirmed line management 8907270164 890719 OMI FDR ADOCK 05000277 I

Document Control Desk Page 2 assessments.
Specific conclusions for each area reviewed are summarized below.
l The MOT discussed plant physical status.
The MOT discussed the failure of a main steam line low pressure isolation switch and its i
subsequent replacement.
This was determined to be an isolated I
material failure.
A small EHC leak on the number seven turbine bypass valve low pressure drain is being closely monitored.
The present leakage rate was determined not to adversely impact safe and reliable plant operations.
The MOT accepted the maintenance report that the feedwater control switch failure was an isolated incident.
]
The multiple fuse failures on the main generator potential f
transformers were discussed.
Generic implications were considered.
l The diesel generators were found to have similar fuses and a program i
is underway to replace the fuses during the diesel annual outage.
f Control system tuning and the plant's response to the planned transients were discussed.
At the present time, repairs are being l
made to the "B"
feed pump motor control unit.
Repairs will be l
completed before reaching 100% power.
The MOT concluded that the I
plant performed satisfactorily.
Operations continuing strengths include good communications and cooperation between groups during major plant evolutions, prompt and thorough event and incident investigations, timely completion of procedural changes, and prompt and conservative actions taken in response to off-normal conditions.
Routine daily operations meeting effectiveness has improved; however, line managament attention
{
continues in this area.
Staffing levels with respect to simultaneous support of Unit 2 operations, Unit 2 thirteen (13) week rolling maintenance schedule, Unit 3 outage support, and operator progression training have shown improvement.
Four licenses have been converted from " cold" to " hot", and 100% of the reactivity manipu.tations and approximately 70% of the shifts above 20% power have been completed by shift personnel.
Based upon this progress, we anticipate the conversion of the remaining shift personnel " cold" licenses to " hot" licenses by mid-August 1989.
Maintenance continuing strengths include plant material condition and effective maintenance troubleshooting and repairs in response to problems.
The MOT noted a continuing positive trend in maintenance backlog reduction and additional significant improvement in the ability to meet the 13 week rolling maintenance schedule since the June 23, 1989 meeting.
An area indicating improvement, but identified for continuing line management attention, is the repair of out-of-service Control Room instrumentation.
1 Services (chemistry, health physics and radwaste) continuing j
strengths include good and improving housekeeping, improving industrial safety and radiological worker practices, minimized spread of contamination and improved group communications.
In addition, chemistry continues to manage activities to meet chemistry specifications and optimize the further reduction of impurities.

copper reduction action plan has been approved by Philadelphia Electric management for feedwater copper removal during the increase to 100% power.
Considerable effort has been expended to reduce the l
number of incidents leading to Radiological Occurrence Reports resulting in a downward trend.
Technical support continuing strengths include good intergroup communications, procedural adherence, knowledgeable and responsive personnel, and prompt identification of problems and completion of i
corrective actions.
Improvements were made to the method of reporting surveillance tests.
The completion of surveillance tests is being done in a timely manner and is being monitored properly.
i l
Areas for continuing line management attention are the completion of documentation related to delayed surveillance test completion and f
operational verification forms.
Security continuing strengths include improvement in personnel performance, improvement in personnel training, improvement in contingency drill participation, and improvement in reliability of j
detection equipment.
j ANI, NRC and Commonwealth of Pennsylvania, State of Maryland and co-owner representatives who attended one or both of the MOT meetings provided no adverse comments.
The MOT reviewed outstanding action items from the previous meetings and determined that closure was satisfactory or that continuation of open items would not adversely impact the safe operation of Unit 2 at 100% power.
In consideration of the above, we are requesting that the Regional Administrator, Region I modify the March 31, 1987 order to permit operation of' Unit 2 at 100% power in accordance witu the approved Restart Power Testing Program.
