6 LER CONTII'UATION -- ROM 2-79-042 Facility: BSEP Unit No. 2 Event Date: 6-6-79 600 pounds of borax vere added along with water to bring the solution to 3500 gallons with a concentration of 14.27. Both lines were capped and checked for leakage. The isolation valves on these lines will be worked during the next outage of sufficient duration. An entry in the daily instructions has instructed all operators to be aware of possibla leaks in the SLC system and to inspect the systen for such leaks on a contin-uing basis. This entry applies to both units. Unit No. 2 was in cold shutdown throughoug this incident. t. e e }}
