SUBJECT:
1986 Annual Report of all Challenges to Safety / Relief Valves for Limerick Generating Station Unit 1 - Report No. 2 Revision No. 1
Dear Dr. Murley:
This represents the 1986 Annual Report of all challenges to Safety / Relief Valves for Limerick Generating Station, Unit 1 as required by Technical Specification 6.9.1.5.b.
The definition of challenges considered in this report is the automatic opening of main steam system safety / relief valves in response to high reactor pressure.
During 1986, there were no automatic openings of the main steam safety / relief valves in response to high reactor pressure.
On January 2, 1986, the main steam system safety / relief valves were manually opened to control reactor pressure during cooldown following the loss of condenser vacuum.
On June 18, 1986 the Automatic Depressurization System (ADS) Safety Relief Valves (S, H, M,
E, K) were manually opened to conduct a Surveillance Test (ST-2-05-760-1), which was performed satisfactorily.
l A documentation of all challenges to the main steam i
system safety / relief valves has been submitted as part of the l
monthly operating report in order to comply with Technical Specification 6.9.1.6.
