OR INFORMATION ON PLANT'YSTEHS 3/4.7. 9 SNUBBERS LIHITIHG CONDITIOH FOR OPERATIOH 3.7. 9 All hydraulic and mechanical snubbers shall be OPERABLE. The only snubbers excluded from this requirement are those installed on nonsafety-related systems and then only if their failure or failure of the system on which they are installed, would have no adverse effect on any safety" related system.

APPLICABILITY: NODES 1, 2, 3, and 4. NODES 5 and 6 for snubbers located on systems required OPERABLE in those NODES.

ACTION:

Pith one or more snubbers inoperable on any system, 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 4.7.9g. on the attached component or declare the attached system inoperable and follow the appropriate ACTION statement for that system.

SURVEILLANCE RE UIREHENTS 4.7.9 Each snubber shall be demonstrated OPERABLE by performance of the follow'ing augmented~service inspection program and the requirements of Specification 4.0.5~+

~5T As used in this specification; type of snubber shall mean snubbers of the same design and manufacturer, irrespective of capacity.

b. -.Visual Inspections Snubbers are categorized as inaccessible or accessible during reactor operation. Each of these categories (inaccessible and accessible) may be inspected independently according to the schedule determined by Table 4.7-2. The visual inspection interval for each type of snubber shall be determined based upon the criteria provided in Table 4.7-2 and the first inspection interval determined using this criteria shall be based upon the previous inspection interval as established by the requirements in effect before Amendment No.57

-"INSERT A PALO VERDE - UNIT 1 3/4 7-21 ANEHDHENT NO. 57

INSERT A For functional testing performed during the third refueling outage, the selection of the snubber test samples was not performed in accordance with the requirements of the Specification. The methodology described in licensee correspondence dated May 20, 1993 was used for the sample selections for this testing and adequately demonstrated the operability of the snubber population.
