APPENDIX A NOTICE OF VIOLATION Arkansas Power and Light Company Dockets : 50-313 Arkansas Nuclear One, Units 1 and 2 50-368 Licenses:
DPR-51 NPF-6 r
Based on the results of an NRC inspection conducted during the period of bbrch 1-31, 1982, and in accordance with the Interim Enforcement Policy 45 FR 66754 (October 7, 1980), the following violations were identified:
1.
Unit 2 Reactor Protection Channel Not Tripped When Required Unit 2 Technical Specification 3.3.1.1 requires that the reactor protec-tive instrumentation channels of Table 3.3-1 shall be operable. This a
table requires that three of the four channels of Linear Power Level-High be operable in Mode 1, and refers ta Action Statement number two. This action statement provides that power operation may continue with one of the four channels inoperable, provided that the inoperable channel is bypassed or tripped within one hour and either restored to operable status or tripped within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> from the initial loss of operability.
Contrary to the above, on March 22, 1982, with the unit operating in Mode 1, the Channel C excore nuclear instrumentation had been inoperable for more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, but the Channel C Linear Power Level-High was not tripped. This condition was observed by the NRC inspector at 1610 hours0.0186 days <br />0.447 hours <br />0.00266 weeks <br />6.12605e-4 months <br />, and the channel was tripped by the licensee at 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br />.
This is a Severity Level IV Violation.
(Supplement I.D.2) (368/8205-01) 2.
Two of Three Unit 1 High Pressure Injection Pumps Inoperable Unit 1 Technical Specification 3.3.2 requires that two of the three High Pressure Injection pumps shall be maintained operable when the Reactor Coolant System temperature is greater than 350F and irradiated fuel is in the core.
Contrary to the above, the licensee reported in Licensee Event Report 82-003/03L-0 that the oil was changed in Pump P-36A while Pump P-36C was out of service, resulting in having only one High Pressure Injection Pump operable on January 28, 1982.
This is a Severity Level IV Violation.
