Northern States Power Company Docket Nos. 50-282; 50-306 Prairie Island Nuclear Generating Plant License Nos. DPR-42; DPR-60 During an NRC inspection conducted from October 9 through November 19, 1996, i
violations of NRC requirements were identified.
In accordance with the
" General Statement of Policy and Procedure for NRC Enforcement Actions,"
NUREG-1600, the violations are listed below:
Technical Specification 6.5.A.4 required that detailed written procedures covering surveillance and testing requirements that could have an effect on nuclear safety shall be prepared and followed.
Surveillance Procedure SP 1305, "D2 Diesel Generator Slow Start Test,"
revision 13, was one procedure prepared in accordance with that specification.
Contrary to the above, on October 30,1996, SP 1305 was not followea in that licensee operators failed to perform steps 7.67.3 and 7.67.4 to ensure the diesel engine would not start during an air roll.
i This is a Severity Level IV Violation (Supplement I).
Technical Specification 3.7.B.1 required, in part, that during startup or power operation, one diesel generator may be inoperable for 7 days provided that operability of the other diesel generator is demonstrated 3
by performance of surveillance requirement 4.6.A.1.e within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
That requirement applied unless the diesel generator was inoperable due to preplanned preventative maintenance or testing.
Contrary to the above, on November 14, 1996, while Unit 2 was operating at full power, the D5 diesel generator was declared inoperable due to a 2
problem with its ventilation system. Surveillance requirement 4.6.A.I.e was not performed to demonstrate operability of the redundant D6 diesel generator.
This is a Severity Level IV Violation (Supplement I).
