l l Technical Specification Surveillance Requirement (SR) 3.8.1.11.c.1 l requires that once every eighteen months it be verified that on an j actual or simulated loss of offsite power signal each emergency diesel generator energizes permanently connected loads in < 12 seconds. Licensee Procedure CPS 9080.23. " Diesel Generator 1C Integrated." was intended to satisfy this SR.
ENCLOSURE 1 Notice of Violation and Proposed Imposition of Civil Penalty SR 3.0.1 states, in part, that " failure to meet a SR whether such .
failure is experienced during Jerformance of the SR or between :
performances of the SR shall )e failure to meet the LCO."
Contrary to the above. from September 26, 1995. until November 5, 1996. Diesel Generator 1C was inoperable in that SR 3.8.1.11.c.1 could not be satisfied. On September 26. 1995, the licensee miscalibrated relay K54X. The miscalibration directly caused, on November 2,1996, the inability of Diesel Generator 1C to satisfy SR 3.8.11.c.1 in that it could not be demonstrated that permanently connected loads were energized in less than 12 ,
seconds. As demonstrated through the performance of Procedure CPS :
9080.23. loads were not energized until 20 seconds after receipt of the actuation signal.
- 2. 10 CFR Part 50. Ap)endix B. Criterion III. " Design Control."
states, in part, tlat measures shall be established to assure that applicable regulatory requirements and the design basis as specified in the license application, for those structures, systems, and components to which this appendix applies are l correctly translated into specifications, drawings, procedures. ,
and instructions. '
10 CFR Part 50. Apaendix B. Criterion XVI, " Corrective Actions" states, in part, tlat measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and j l nonconformances are promptly identified and corrected. '
Contrary to the above, on August 1. 1995, the licensee failed to i correctly translate the design basis for the closing time of '
l Diesel Generator _IC output breaker when the 3reventative i maintenance task evaluation request sheet PEiDGM025 to calibrate
( relay K54X. " Permissive Signal for Closure of the Division III EDG l Output Breaker" was issued. Specifically, the licensee 4 i incorporated the wrong delay time in PEMDGM025 which directly i caused the closure time of Diesel Generator 1C output breaker to be in noncompliance with Technical Specifications. On i September 26. 1995, the licensee failed to identify and correct a ,
l condition adverse to quality when workers found a substantial i discrepancy between the as-found set point of .55 seconds and j as-left set point (specified in PEMDGM025) of 11.28 seconds for l
the K54X relay. The licensee's failure to properly translate design requirements into working instructions (PEMDGM025), and the ,
failure to both identify as a nonconformance and take corrective '
actions for the substantial difference between the as found and as left setpoints for the K54X relay contributed to Diesel Generator 1C being inoperable from September 26. 1995, to November 5, 1996, as described in violation C.1. 1 This is a Severity Level III problem (Supplement I).

ENCLOSURE 2 CIVll PENALTY ASSESSMENT A. Reactor Recirculation Pumo Seal Failure Section A of the Notice contains two violations. These violations pertain to the operating crew's deliberate actions which resulted in failing to comply with the specific procedure step sequence when isolating the idle reactor coolant loop. Specifically, the crew failed to allow the idle loop to cool to the specified temperature before completing the isolation procedure. Failirig to allow the loop to cool directly contributed to further degradation of the seal, drywell leakage exceeding the technical specification limits, and the seal's ultimate failure.
These violations demonstrated that the administrative system for procedure compliance, which was designed to prevent or mitigate a serious safety event, did not perform its intended function. The evolution demonstrated that Illinois Power Company inappropriately
- emphasized attaining a single loop configuration to allow continued Sower operation over the conservative decision to shut down the unit.
Juring the predecisional enforcement conference, the CPS managers acknowledged that the management team had defined procedure compliance as " meeting the intent of 3rocedures" and not complying with the written l procedure. In addition. C)S managers acknowledged that the crew was
" set up " Their acknowledgement was based on the established definition j of procedure compliance: the material condition of the plant: the number '
of operator work arounds: the lack of simulator training on tht event; i the fact that a reactor operator, the shift supervisor and the line assistant shift supervisor were not part of the regular crew, and the crew was thrown into a situation that was very complicated and different from something that they had performed before. These actions
, demonstrated a careless disregard by CPS for procedural requirements.
Therefore, in accordance with NUREG-1600, the two violations are of very significant regulatory concern and have been categorized in the aggregate as a Severity Level 11 problem.
l In accordance with the Enforcement Policy, a base civil 3enalty in the amount of $80,000 is normally considered for a Severity _evel II l violation. As noted above, particularly poor performance was demonstrated by CPS before, during, and after the event. Specifically, the event and NRC follow-up activities revealed fundamental weaknesses in the CPS operations and engineering departments in the areas of safety l focus, procedure quality and adherence. conservative decision making, and engineering support to operations. Substantial NRC involvement was needed to assure that CPS conducted a comprehensive assessment of the issues and implement subsequent corrective actions. The corrective actions proposed by CPS focused on conservative decision-making.
appropriate safety focus, procedure compliance. procedure adequacy, and appropriate 10 CFR 50.59 appreciation and implementation. The NRC would j expect these corrective actions to be effective at improving i

ENCLOSURE 2 Serformance. However, at the March 20. 1997. enforcement conference 1 eld to discuss the radiological control violations --discussed in paragraph B. " Failure to Follow Procedures" below-- the licensee's corrective actions were focused narrowly on each violation, and did not address the fundamental root causes of procedure quality and adherence '
problems. In addition, several of the violations discussed in paragraph B. occurred significantly after the September 5,1996, event. This demonstrated that the initial procedure compliance corrective actions were not fully' effective.
In view of the circumstances of these very significant violations. NRC is exercising discretion in accordance with Section VII.A of NUREG-1600 and assessing a civil penalty in the maximum amount of $100.000 for each violation for a total of $200.000. This represents the maximum daily ;
civil penalty allowed each violaticm.
B. Failure to Follow Procedures Section B of the Notice contains ten violations associated with o)erations and seven violations associated with radiation protection.
T1ese violations address a breakdown in the control of activities involving adherence to procedures and collectively represent a potentially significant program breakdown. The ten operational violations pertained to fundamental procedure adherence problems pervasive in the operations and engineering departments. They included failure to control valve status (spent fuel pool cooling and control
. room heating and ventilation): failure to notify other departments (chemistry and health physics) after power level changes: and lack of i
rigor. in conduct of o)erations (individual turnovers. SRO monitoring plant conditions). T1ese violations demonstrated that site management accepted an environment that permitted and accepted that procedures were treated as guidance and did not have to be followed as written.
l The seven radiation protection violations pertained to CPS's failure to implement its radiation protection program and were indications of a programmatic breakdown. The root causes for these violations are similar to the operational violations. The procedural adherence and
< procedural adequacy problems were clearly demonstrated by the l unauthorized entry of workers into the upper levels of the drywell, the ,
unnecessary spread of contamination when workers disconnected a pressurized sludge sluicing line without properly evaluating the potential radiological hazards, the failure to appropriately respond to
, alarming personnel portal monitors. the failure to properly exit a l posted contaminated area, and the failure to adequately evaluate radiological ' conditions prior to permitting workers to remove insulation.
Therefore, in accordance with NUREG-1600, these seventeen violations have been categorized in the aggregate as a Severity Level III problem.

In accordance with the Enforcement Policy, a base civil Senalty in the amount of $50,000 is normally considered for a Severity _evel III
- problem. Accordingly. the corrective action deficiencies and need for NRC intervention as discussed in )aragraph A are also applicable to this .
item. It was noted that during t1e inspection, individuals rationalized i that it was acceptable to not follow existing procedures in order to accomplish work activities. Moreover, during the May 20. 1997, predecisional enforcement conference. CPS failed to discuss the radiation protection issues from a broad perspective and as they related to the procedural adherence problems discussed at the previous t
-enforcement conferences. This indicated to the NRC that CPS was not taking this opportunity to look collectively at all of its programs and ;
implement effective long-term corrective actions. In addition, the :
radiation protection violations occurred sufficiently after the i September 5.1996 event, to demonstrate that CPS was having difficulty implementing effective corrective actions for procedure compliance problems. Therefore, corrective action credit is not warranted. In :
view of the circumstances of this significant problem NRC has decided ,
to exercise discretion in accordance with section VII.A of NUREG-1600 and collectively assess a civil penalty in the amount of $100.000 (twice the base) for this Severity Level III problem.
C. Inocerable Division III Emeraency Diesel Generator (EDG) '
Section C of the Notice contains two violations. These violations relate to the Division III EDG being inoperable for approximately a year. The inoperability was caused by an inadequate calibration 3rocedure for a relay associated with the Division III EDG output i areaker. The procedure had been changed without sufficient engineering ,
reviews to ensure that the proper setting had been incorporated. In !
addition. this error should have been identified during the calibration, if the CPS staff had questioned the large discrepancy between the as-found and as-left settings or documented this discrepancy on an upper-tier corrective action document for subsequent review and resolution. This violation demonstrates a significant failure during the development of the calibration procedure. a failure to resolve a discrepancy between the as-found and as-left sequencer relay, and a failure to capture the discrepancy on an upper tier corrective action document. These failures resulted in the Division III EDG rendered ino)erable for approximately a year. Therefore. in accordance with NUREG-1600 the two violations have been categorized in the aggregate as a Severity Level III problem.
In accordance with the Enforcement Policy, a base civil penalty in the l
amount of $50.000 is normally considered for a Severity Level III l problem absent prompt and comprehensive corrective action. The l corrective actions described at the predecisional enforcement conference
- included the replacement and calibration of the relay. verifying correct
- operation of the relay through an integrated surveillance test. !
- clarifying the related drawing, verifying correct relay setpoints on the l other EDGs. and lowering the threshold for documenting out-of-tolerance i

l conditions in the corrective action systems. Although the NRC i acknowledges these corrective actions, it was concluded that credit for '
corrective action credit was not warranted, because CPS had ample opportunity to identify this problem from the time that an engineering clerk discussed the setpoint with a design engineer because the setpoint range specified on the electrical drawing was not clear. The Engineering department failed to refer to other documentation to verify the correct setpoint and there was no engineering review of the preventive maintenance package for revising the setpoints. In addition, l maintenance 3ersonnel did not initiate a condition report when they i discovered t1e new setpoint was much greater than the as-found setting on the relay. Finally, two 1996 condition reports had been written regarding failures to trend instrumentation preventive maintenance failures which should have alerted CPS to this issue. A proper response on any of these occasions could have prevented the diesel generator from being inoperable for an extended period. For this reason corrective action credit is not warranted. In view of the circumstances of this significant problem, the NRC, in accordance with Section VI.B.2 of NUREG-1600, is assessing a civil penalty in the amount of $50,000 for this Severity Level III problem.
D. Failure to Perform Safety Evaluation Section D of the Notice contains seven violations where safetj evaluations required by 10 CFR 50.59 were not performed. These included 1 examples where tests affecting safety-significant"cperable systems (residual heat removal) were performed without safety evaluations or approved procedures; procedures were changed without safety evaluations:
and systems identified as different from the plant's Updated Safety i
Analysis Report were not evaluated to ensure unreviewed safety cuestions i did not exist. The seven violations are collectively considerec a Severity Level III problem. These violations demonstrate a significant failure to meet the requirements of 10 CFR 50.59 in that, these ,
l evaluations failed to ensure unreviewed safety issues were not !
introduced by the tests, procedure changes, or design changes, i Therefore in accordance with NUREG-1600, the seven violations have been l categorized as a Severity Level III problem. ,

E. Ineffective Corrective Actions to Resolve Inocerable Containment l Penetrations j Section E of the Notice contains two violations which address CPS's failure to implement effective corrective actions and resolve inoperable i feedwater containment penetrations. These penetrations have routinely i failed their as-found refueling frequency surveillance tests since the first refueling outage to the current (sixth) refueling outage.
Additionally. CPS changed the test method during the fifth refueling outage, resulting in a containment penetration test configuration
- different than the system configuration that the containment penetration would see subsequent to a design basis accident. As a result of this !
change, the license was not able to demonstrate that repairs performed .
to the penetration during the fifth refueling outage were successful. !
Therefore, in accordance with NUREG-1600 the two violations have been categorized in the aggregate as a Severity Level III ,roblem. 1 In accordance with the Enforcement Policy a base civil Senalty in the amount of $50.000 is normally considered for a Severity _evel III problem absent prompt and comprehensive corrective action. The ,
licensee's corrective actions included revising the applicable ;
surveillance procedures, implementing a continuing review of other surveillance procedures to identify and correct other testing ;
deficiencies, and implementing an extensive modification to the penetratiors to address the root cause of the failures. Although the ,
NRC acknowledges these corrective actions it concluded that credit for !
Corrective Action was not warranted, based on the fact that the licensee !
had ample opportunities to collectively address the test failures during previous outages and implement effective corrective action It was not until the NRC intervened during the current refueling outage that the :
licensee attempted to address and resolve the repeated failures of the {
penetrations. For this reason. Corrective Action credit is not ;
warranted. In view of the circumstances of this significant problem. I the NRC. in accordance with section VI.B.2 of NUREG-1600, is assessing a i civil penalty in the amount of $50,000 for this Severity Level III l problem.
