PLANT SYSTEMS 3/4.7.7 SNUBBERS 1
LIMITING CONDITION FOR OPERATION 3.7.7 All snubbers listed in Tables 3.?-4a and 3.7-4b shall be OPERABLE.
APPLICABILITY: MODES 1, 2, 3 and 4.
MODES 5 and 6 for snubbers located on systems required OPERABLE in those MODES.
ACTION:
With one or more snubbers inoperable, within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> replace or restore the inoperable snubber (s) to OPERABLE status and perform an engineering evaluation per Specification 4.7.7.g on the 1ttached component or declare the attached system inoperable and follow the appropriate ACTION statement for that system.
SURVEILLANCE REQUIREMENTS 4.7.7 Each snubber shall be demonstrated OPERABtE by performance of the following augmented inservice inspection program and the requirements of Specification 4.0.5.
a.
Inspection Types As used in this specification, type of snubber shall mean snubbers of the same design and manufac.turer, irrespective of capacity.
b.
Visual Inspections The first inservice visual inspection of each type of snubber shall be performed after 4 months but within 10 months of commencing POWER OPERATION and shall include all snubbers listed in Tables 3.7-4a and 3.7-4b.
If less than two snubbers of each type are found inoperable during the first inservice visual inspection, the second inservice visual inspection shall be performed 12 months i 25% from the date of the first inspection. Otherwise, subsequent visual inspections shall be performed in accordance with the following schedule:
No. Inoperable Snubbers of each Subsequent Visual,
type per Inspection Period Inspection Period
- 0 18 months i 25%
1 12 months i 25%
2 6 months i 25%
3,4 124 days i 25%
5,6,7 62 days i 25%
8 or more 31 days i 25%
AThe inspection interval for each type of snubber shall not be lengthened more than one step at a time unless a generic problem has been identified and corrected; in that event the inspection interval may be lengthened one l
step the first time and two steps thereafter if no inoperable snubbers of that type are found.
