SUBJECT:
Final Requalification Program Evaluation Report
Dear Mr. Bette ihausen:
i lhis report provides the facility evaluation of the Licensed Operator Requalification Examinations administered by the NEC to eight (8) licensees at Peach Bottom Atomic. Power Station (PBAPS) from March 9 - 12, 1993.
The number of Licensed Operators examined by the NRC this year, combined with the licensees examined in 1992, was sufficient to perform a program evaluation using the 'riteria set forth in the Operator Licensing Examiner Standards (NUREG-1021) Section ES-601.
Post examination review indicators and results from Philadelphia Electric Company examinations administered during the periods of March 9 - 12, 1992 and March 9 - 12, 1993 have shown the-Licensed Operator Requalification Program to be SATISFACTORY with no 9eneric weaknesses.
The following attachments detail various aspects of the examinations administered between March 9 - 12, 1993.

PBAPS IDENTIFIED STRENGTHS AND AREAS FOR IMPROVEMENT -
The following strengths and areas for improvement were determined from a systematic analysis l
of the examination results. Actions to address the areas for improvement will be taken in accordance with established facilit3 processes..
I.
DYNAMIC SIMUIATOR EVALUATIONS A.
Procedure use and compliance in general was noted as a strength with the following
[
items specifically addressed:
I.
Strengths Emergency ResIxmse procedures were promptly and accurately carried out.
a.
b.
Technical Specification limiting conditions for Operations were promptly i
and accurately determined.
2.
Areas for Imorovement Alarm Response card use, though very good, must include a review of all key a.
alarms.
b.
Operational Transient and Ofr Normal procedures should be implemented during Transient Resp (mse procedure use.
Securing of ECCS stayfull systems during the performance of T-240 should.
c.
not delay plant emergency depressurization.
f d.
Alternate means of negative reactivity insertion should be pursued while establishing minimum alternate flooding pressure, e.g., driving individual rods using T-220.
B.
Command and Control in general was noted as a strength with the following items specifically addressed:
I.
Strencths Supervisory directives were conservative and allowed safe and integrated crew a.
performance.
b b.
Most actions were taken to pmvide early remediation of plant problems.
2.
Areas for improvement Supervisory directives must provide clear goals and objectives. e.g., post a.
ATWS establishment of adequate core cooling.
J
Attechment 2 Page 2 of 4 t
b.
Personnel task assignments should allow for full attention to important tasks i
c.g., terminating and preventing injection and establishing minimum -
alternate flooding pressure.
t Shill Manager's maintenance of an mersight role was very good w hile c.
providing a proper mix of ERP duties and TRIP procedure review.
C.
Teamwork and Communications in general were noted as strencths with the following items specifically addressed:
I.
Strencths Crew briefs were effective in establishing early action plans, goals and a.
objectis es.
t b.
Shift Manager and Shift Technical Advisor oversight and SSV assistance roles were valuable assets used for team success.
Outside support was promptly obtained as well as outside personnel c.
promptly informed of plant conditions.
2.
Areas for Improvement Individual communication should include consistent acknowledgement of receipt.
D.
Control Board Operations were noted as satisfactory with the following anas specifically addressed:
Areas for Improvement 1.
Chief Operator initial scram actions must ensure prompt verification of PCIS isolations to prevent any delay in recognition of failures.
1 2.
Electrical loss diagnosis must be complete to prevent attempting to close in on a bus which has a fault, t
3.
When directed to perform a normal depressurization assertive action is required to ensure it is initiated promptly.
l 4.
Reactor automatic scram should not be relied on during a loss of feedwater, rather a manual scram should be initiated.
5.
Ensure RIIR injection lineups are secured prior to initiation of Containment Spray lineups.
