Facility:
Crystal River Unit #3 3.
Report Date:
3 June 1977 4.
Occurrence Date:
14 May 1977 5.
Identification of occurrence:
Hydraulic Snubber MUH-44 inoperable contrary to Table 3.7-3 of Technical Specification 3. 7.9.1.
6.
Conditions Prior to Occurrence:
In Mode 5, Cold Shutdown, performing SP-201.
7.
Description of Occurrence:
o At 1400, in the process of performing the Hydraulic Snubber Inspection SP-201, Snubber MUC-44, located on the 2-1/2" H.P. injection line in the Reactor Building, was discovered disconnected from the snubber eye to the pipe clamp. The snubber ss removed and renewed with a functionally tested spare. MUH-44 was restored operable within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
