i ATTACHMENT -

RI-90-A-136 Numerous work orders and design changes have been performed on radiation monitors RM-8262 and RM-8123 during the period June - August 1990. The fol-lowing items have been identified.

1. a. ,

Work on the flow control valve, including replacement, commercial grade dedicatiori, and retesting was conducted under AWO M2-9004311 while the AWD only authorized work on the system bypass valves.

b.

The flow control valve failed an initial 60 psi leak check, but this failure was not dispositioned.

c.

There was not adeauate communication between maintenance and opera-tions to ensure that proper actions were conducted when the monitors were inoperable.

(1) From July 23 to August 4 neither monitor was operable, and compensatory actions were not taken. (The inoperability was due to in progress system design change work.)

(2) On July 26 RM-8262 was out-of-service to change filters and RM-8123 was out-of-service due to a failed low flow alarm, but no Technical Specification Action Statement was logged and no l

compensatory measures were taken. (Please address separately from (1).)

d.

Drawings have not been updated as a result of the above design change work.

2.

AWO M2-9008033 installed a bypass jumper (Jumper Card #3) without required documentation. (No Bypass-Jumper log entry and no PDCE.) The tag was clearea on August 31, 1990.
