Dear Mr. Davis:
SUBJECT:
Dairyland Power Cooperative La Crosse Boiling Water Reactor (LACBWR)
Provisional Operating License No. DPR-45 Special Report
REFERENCES:
(1) LACBWR Technical Specifications, Section 4.2.18.1 (2) 'LACBWR Technical Specifications, Section 6.9.2-(3) DPC Letter, Taylor to Davis, LAC-12439, November 18, 1987.
In accordance with References 1 and 2, this letter serves as the follow-up to the Special Report submitted in Reference 3.
The internal portion of the fire suppression water system was removed from service at 0630 on November 18, 1987 in order to replace a section of piping. The two diesel-driven High Pressure Service Water Pumps control switches were turned off. The procedure controlling the internal fire suppression system removal from service states the pumps should be started if a fire occurs. Hoses were laid from the yard hydrants to areas inside the plant to provide backup fire suppression capability prior to removing the internal portion of the system from service.
A tee with an approximately 8 foot section of HPSW piping was replaced.
The piping'was successfully hydrostatically tested on November 20, 1987. The fire suppression system was returned to service at 1525 on November 20, 1987.
The plant has been permanently shut down and the reactor defueled.
