1. Technical Specification 3.6.2.2.b requires that the_ containment spray chemical addition system shall- be operable in Modes 1,_2, 3, and 4, j

L 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 gpm)(yingfor each 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.

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 System p(MESAC) surveillance Bwls 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. '
