PLANT SYSTEMS 3/4.7.8 SNUBBERS LIltITING CONDITION FOR OPERATION 3.7.8.1 All snubbers listed in Table 3.7-4 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 0.02 hours 1.190476e-4 weeks 2.7396e-5 months replace or restore the inoperable snubber (s) to OPERABLE status, and perform an engineering evaluation

per Specification 4.7.8.b. and c. on the supported component or declare the supported system inoperable and follow the appropriate ACTION statement for that system.

SURVEILLANCE REQUIREMENTS 4.7.8.1 Each snubber shall be demonstrated OPERABLE by performance of the following augmented inservice inspection program and the requirements 'of Specification 4.0.5.

a.

Visual Inspections Visual inspections shall be performed in accordance with the following schedule:

No. Inoperable Snubbers Subsequent Visual **

per Inspection Period Inspection Period #

0 18 months + 25%

1 12 months T 25%

2 6 months I 25%

3, 4 124 days 125%

5, 6, 7 62 days 1 25%

8 or more 31 days 1 25%

The snubbers may be categorized into two groups: Those accessible and those inaccessible during reactor operation.

Each group may be inspected jndependently in accordance with the above schedule.

A documented, visual inspection shall be sufficient to meet the requirements for an engineering evaluation. Additional analyses, as needed, shall be completed in a reasonable period of time.

The inspection interval shall not be lengthened more than two steps at a time.

The provisions of Specification 4.0.2 are not applicable.

CALVERT CLIFFS - UNIT 2 3/4 7-25 Amendment No. J p,.1 6

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) b.

Visual Inspection Acceptance Criteria Visual inspections shall verify (1) that there are no visible indications of damage or impaired OPERABILITY, and (2) that the snubber installation exhibits no visual indications of detachment from foundations or supporting structures.

Snubbers which appear inoperable as a result of visual inspections may be determined OPERABLE for the purpose of establishing the next visual inspection interval, providing that (1) the cause of the rejection is clearly established and remedied for that particular snubber and for other snubbers that may be generically susceptible; and/or (2) the affected snubber is functionally tested in the as found condition and determined OPERABLE per Specification 4.7.8.d, as applicable.

3 When the fluid port of a hydraulic snubber is found to be uncovered, I

the snubber shall be determined inoperable unless it can be deter-mined OPERABLE via functional testing for the purpose of establish-ing the next visual inspection interval.

For the snubber (s) found inoperable, an engineering evaluation shall be performed on the component (s) which are supported by the snubber (s). The scope of this engineering evaluation shall be consistent with the licensee's engineering judgment and may be limited to a visual inspection of the supported component (s). The purpose of this engineering evaluation shall be to determine if the component (s) supported by the snubber (s) were adversely affected by the inoperability of the snubber (s) in order to ensure that the supported component remains capable of meeting the designed service.

c.

Functional Tests At least once per 18 months during shutdown, a representative sample j

of 10% of the snubbers in use in the plant shall be functionally tested either in place or in a bench test.* For each snubber that i

does not meet the functional test acceptance criteria of Specifica-tion 4.7.8.d, an additional 5% of the snubbers shall be functionally tested until no more failures are found or until all snubbers have been functionally tested.

I

The Steam Generator snubbers 2-63-11 through 2-63-26 need not be functionally I tested until the refueling outage following June 30, 1985.

CALVERT CLIFFS - UNIT 2 3/4 7-26 Amendment No. J0, M, M,7 3 e

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

)

Snubbers identified in Table 3.7-4 as "Especially Difficult to Remove" or in "High Exposure Zones" shall also be included in the representative sampl e.

In addition to the regular sample, snubbers which failed the previous functional test shall be retested during the next test period.

If a spare snubber has been installed in place of a failed snubber, then both the failed snubber (if it is repaired and installed in another position) and the spare snubber shall be retested during the next test period. Failure of these snubbers shall not entail functional testing of additional snubbers.

If any snubber selected for functional testing either fails to lock up or fails to move, i.e.,

frozen in place, the cause will be evaluated and if caused by manufacturer.or design deficiency all generically susceptible snubbers of the same design subject to the same defect shall be functionally tested.

This testing requirement shall be independent of the requirements stated above for snubbers not meeting the functional test acceptance criteria.

For the snubber (s) found inoperable, an engineering evaluation shall be performed on the component (s) which are supported by the snubber (s).

The scope of this engineering evaluation shall be consistent with the licensee's engineering judgment and may be limited to a visual inspec-tion of the supported component (s). The purpose of this engineering evaluation shall be to determine if the component (s) supported by the snubber (s) were adversely affected by the inoperability of the snubber (s) in order to ensure that the supported component remains capable of meeting the designed service.

d.

Hydraulic Snubbers Functional Test Acceptance Criteria The hydraulic snubber functional test shalI verify that:

1.

Activation (restraining action) is achieved within the specified range of velocity or acceleration in both tension and compression.

2.

Snubber bleed, or release rate, where required, is within the specified range in compression or tension.

For snubbers-specifically required to not displace under continuous load, the ability of the snubber to withstand load without displacement shall be verified.

Permanent or other exemptions from functional testing for individual snubbers in these categories may be granted by the Commission only if a justifiable basis for exemption is presented and/or snubber life destructive testing was performed to qualify snubber operability for al1 design conditions at either the completion of their fabrication or at a subsequent date.

CALVERT CLIFFS - UNIT 2 3/4 7-26a Amendment No. #,.fg

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) e.

Snubber Service Life Monitoring

A record of the service life of each snubber, the date at which the designated service life commences and the installation and maintenance records on which the designated service life is based shall be main-tained as required by Specification 6.10.2.m.

At least once per 18 months, the installation and maintenance records for each snubber listed in Table 3.7-4 shall be reviewed to verify that the indicated service life has not been exceeded or will not be exceeded prior to the next scheduled snubber service life review.**

If the indicated service life will be exceeded prior to the next scheduled snubber service life review, the snubber service life shall be re-evaluated or the snubber shall be replaced or reconditioned so as to extend its service life beyond the date of the next scheduled service life review. This reevaluation, replacement, or reconditioning shall be indicatej in the records.

The Snubber Service Life Program shall be fully implemented by January 1,1983.

- The provisions of Specification 4.0.2 are applicable.
