l As'a result of the inspection conducted from March 18 through April and in accordance with 10 CFR Part 2, Appendix C - General Statement of Policy t
L and Procedure for NRC Enforcement Actions (1989), the following violations were identified:
~!
F 1.
Technical Specification 3.6.2.2.b requires that the_ containment spray j
L chemical addition system shall-be operable in Modes 1,_2, 3, and 4, l
L with two spray additive eductors each capable of adding NaOH"(sodium l
hydroxide) solution from the spray additive tank to a containment spray-3 e
system pump flow. The action requirement states:
"With the_ Spray Additive System inoperable, restore the system to OPERABLE status within 1
seven days or be in at least HOT STANDBY-within the next six hours; restore:the Spray Additive System to OPERABLE status within the next 3
48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or be in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />."
Technical Specification 4.6.2.2 states:
"The Spray Additive System shall be OPERABLE:.... d.
at least once per five_ years by verif water flow rate equivalent to 55 (+5, -0) gallons per minute (ying each gpm) for i
the-30%'NaOH from the eductor test connections in the Spray Additive System." Trains A and B must show 68 (+6, -0) gpm each/-
Contrary to the above, on October 19, 1989, Unit 2, Train B of Containment Spray Chemical Additive System was identified as inoperable when the spray additive throttle valve 2C5021B was found fully open vice throttled. This resulted in-an analyzed flow rate of 115 gpm versus 68 -
.(+6, -0) gpm as required.
This condition wac promptly corrected upon identification and had existed at least, since. March 13, 1989 (in excess l
of ten months) when the valve had been mispositioned from an outage.

I 2.
10 CFR 50 Appendix B Criteria V requires that activities affecting quality shall be prescribed by documented instructions, procedure, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or i
drawings.
L Contrary to the above, on March 14, 1990, at approximately 11:31 a.m.,
C an instrument mechanic failed to perform a surveillance procedure step erformance of Micro Electronic Surveillance and Calibration 1during p(MESAC) surveillance Bwls System 3.1.1-338.
Failure to follow the surveillance procedure resulted in an inadvertent actuation of the
- 1RY456 pressurizer power operated relief valve (PORV), which reduced reactor coolant system pressure by 60 psi.
