CAUSE DESCRIPTION AND CORRECTIVE ACTIONS h g i ; o ! l At approximately 1200 on 10-22-80, the seal injection flow for each RCP was adjusted l by manual throttle valves to 8 gpm without verifying the total flow (with the modula-15 Iil Itinc sunniv valve F illy nnoni en b lo== e%n ne n n ,, a en u , , , . , When the STP was I perfor=ed this problem was discovered and the flow'was adjusted to have a total flow I'I2I lof less than 31 epm. This incident was discussed with the onerators invnived and 1 the governing operating procedure will be changed to add a precaution to check the l i i ll I total flow when individual flows are adiusted. l t i l41 I l 7 3 3 80 ST $ *I, POW E 9 OTHER STATUS 85 o RY DISCOVERY DESCRIPTION l1_Q,j l l@ 'l1l0l0l@lo i:
