f:0TICE OF VIOLATIO'1 Atto PROPOSED IMPOSITI0fl 0F CIVIL PErlALTIES Sacramento Municipal Utility District Docket fio. 50-312 P. O. Box 15830 License flo. DPR-54 Sacramento, California 95813 EA 82-50 V
On March 1,1982, Rancho Seco personnel attempted to start the "B" liigh Pres-a sure Injection (HPI) punp and it failed to start (LER 82-03). On February 11, 1982, plant personnel found the "B" diesel generator inoperable due to a tripped reverse current relay on the diesel generator output breaker (LER 82-05). A special insoection cf these two events was conducted during the period February 11, 1982 through April 28, 1982.
Two significant violations ofregulatoryrequirementswereidentified./Theseviolationsdemonstratea lack of control of licensed aethities, and that the shift supervisors and i
operators have not been continuously aware of the status of safety-related components. As a result, the plant was operated without the control room 5
operators being aware that one of the two diesel generators was inoperable for 29 hours3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> and that one of the two high pressure injection pumps was inocerable for 66 hours7.638889e-4 days <br />0.0183 hours <br />1.09127e-4 weeks <br />2.5113e-5 months <br />. Auxiliary operators.had been recording information on the pertinent log sheet regarding these two connonents without assuring accuracy.
Recording of inaccurate infomation in plant records appears to have been a major contributor to continued plant operation with the two safety-related f~
components mentioned above out of service.
In addition, operating personnel L
did not respond properly to the diesel generator trouble alam.
In order to emphasize the importance of taking effective corrective actions in response to identified deficiencies in plant safety systems and of ensuring that the operators are aware of the configuration of safety-related equipment, the flRC proposes to impose civil penalties of $120,000 for these matters.
In accornuce with the flRC Enforcement Policy ('.0 CFR Part 2, Appendix C),
47 FR 9987 (March 9,1982), and pursuant to Section 234 of the Atonic Energy I
Act of 1954, as amended ("Act"), 42 U.S.C. 2282, PL 96-295, and 10 CFR 2.250, the particular violations and the associated civil penalty are set forth below:
V_IOLATIO!ls ASSESSED CIVIL PErlALTY t
I.
Technical Specification 3.7.2 C requires, "Both diesel generators shall be operable except that from and after the date that one of the diesel F -
generators is made or found to be inoperable for any reason, reactor operation is permissible for the succeeding 15 days provided that during such 15 days the operable diesel generator shall be load tested daily and L
both startup transfomers are available.
If the diesel is not returned to l-service at the end of 15 days, the other diesel will be started and run with at least minimum load continuously for an additional 15 days.
If at the end of the second 15 days the diesel is not returned to service, the V

Appendix (Continued) reactor shall be brought to the cold shutdown condition within an addi-a tional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />."
Contrary to the above requirements, from 8:20 a.m. on February 10, 1982 to 1:40 p.m. on February 11, 1982, the Train "B" diesel generator was inoper-able for a period of 29 hours3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> and 11 minutes with no load testing of the "A" diesel generator.
Additionally, several procedural errors contributed to exceeding the diesel generator limiting condition for operation. Upon returning the diesel generator to service subsequent to surveillance testing, the improper status of the reverse current relay was not identified and corrected, i.e. the diesel generator was not properly placed in the standby condition. On each subsequent shift during the 29 hour3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> period, the auxiliary operators examined the status of the diesel generator and reported that the fault flag was not tripped. Also, the shift turnover checklists for the shift supervisor and control room operator reported the diesel generator to be nonnal.
In addition, the diesel generator trouble alarm was continually annunciated for the 29 hour3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> period without the cause being identified and corrected.
This is a Severity Level III Violation (Supplement I).
(Civil Penalty - $60,000).
II. Technical Specification 3.3.1.A.2 states in part, "The reactor shall not remain critical, unless the following conditions are met:...Two out of three high pressure injection pumps shall be operable...."
Technical Specification 3.3.2 states that, " Maintenance shall be allowed during power operation on any component (s) in the high pressure cooling system... which will not degrade safety features system A or B below the level of perforance with the single subsystem removed from service....
If the system being repaired is not restored to meet the requirement of specification 3.3.1 within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the reactor shall be placed in a hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />."
Contrary to the above, while the makeup pump was out of service, the "B" High Pressure Injection (HPI) Pump was made inoperable at 7:05 p.m. on February 26, 1982, and continued in that condition unknown to the opera-ting personnel until 1:17 p.n. on March 1, 1982.
Additionally, several procedural errors contributed to exceeding the emer-gency core cooling systen limiting condition for operation (3.3.1.A.2).
Upon returning the HPI pump to service, the circuit breaker charging spring motor disconnect switch for the pump motor was not returned to the correct position. On each subsequent shift during the 66 hour7.638889e-4 days <br />0.0183 hours <br />1.09127e-4 weeks <br />2.5113e-5 months <br /> period, the auxiliary operators examined the status of the HpI pump and reported that the switch was in the correct position. Also, the shift turnover check-lists for the shift supervisor and control room operator reported the HPI pump to be operable.
