1LANT SYSTEMS 3/4 7.10 SNUBBERS _

LIMITING CONDITION FOR OPERATION 3.7.10 All snubbers listed in Tables 3.7-4a and 3.7-4b shall be OPERABLE.

APPLICABILITY:

MODES 1, 2,

3 and 4.

(MODES 5 and 6 f or snubbers located on systems required OPERABLE in those MODES).

1 ACTION:

With one or more snubbers inop e rable, within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> replace or resto re the inop erable snubber (s) to OPERABLE status or declare the supported system inoperable and f ollow the approp riate ACTIOC s tatemenc for that system.

SURVEILLANCE REQUIREMENTS 4.7.10 Each snubber shall be demonstrated OPERABLE by perf ormance of the f ollowing augmented inservice inspection program.

a. Visual Inspections The f irs t inservice visual inspection of snubbers shall be perf ormed af ter f our months but within 10 months of commencing F0WER OPERATION and shall include all s nubbers listed in Tables 3.7-4a and 3.7-4b.

If less then two (2) snubbers are found inoperable during the first inservice visual insp ection, the second inservice visual inspection shall be perf ormed 12 months 125% f rom the date of the f irst inspection.

Otherwise, subsequent visual insp etons shall be perf ormed in accordance with the f ollowing schedule:

No. Inoperable Snubbers Subsequent Visual i

par Inspection Period Iqspection Period *5 0

' ~ ~

3,4 123 days i 25%

5,6,7 62 days i 257.

8 or more 31 days i 25%

The snubbers may be categorized into two group s:

Those accessible and those inaccessible during reactor op e ration.

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

  • The inspection interval shall not be lengthened more tnan one step at a time unless a generic problem has been identified and corrected; in that event the inspection may be lenghtened one step the f irst time and two steps thereaf ter if no inoperable snubbers are f ound.
  1. The provisions of Specification 4.0.2 are not applicable.

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) a

b. Visual Inspection Acceptance Criteria Visual inspections shall verify (1) that there are ho Uisible indicationa of the damage or impaired OPERABILITY, (2) attachments to the foundation or supporting structure are secure.

Snubbers which appear inoperable as a r esult of visual inspections may be determined OPERABLE for the purpose of establishing the next visual inspection interval, providing that (1) the cause of ti e rej ection 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 Specifications 4.7.10.d or 4.7.10.e, as applicable.

I

c. Functional Tests At least once per 18 months during shutdown, a representative sasple* (10% of the i

snubbers listed in Tables 3.7-2a and 3.7-2b) shall be functionally tested either in place or in a bench test.

For each snubber that does not meet the functional test acceptance criteria of Specification 4.7.10.d or 4.7.10.e, an additional 107.

of that type of snubber shall be functionally tested. ' Functional testing shall continue until no additional snubbers are found inoperable or all snubbers listed in Tables 3.7-2a and 3.7-2b have been tested.0 The representative sample selected for functional testing shall include the various configurations, operating environments and the range of size and capacity of snubbers.

1 Snubbers identified in Tables 3.7-2a and 3.7-2b as "Especially Difficult to Remove" or in "High Exposure Zones During Shutdown" shall also be included in the representative sample.**

Tables 3.7-2a and 3.7-2b may be used jointly or separately as the basis for the sampling plan.

/

In addition to the regular sample, snubbers which failed the previous functional s

test shall be retested during the next test period.

If a' spare snubber has been Ins talled 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.

Test results of these snubbers shall not result in additional functional testing due to failure.

1 l

  • The requirements of this section for functionally testing mechanical snubbers may be waived until startup following the fifth refueling outage for Unit 1
  • *Pe rmanent or other exemptions from the functional testing for individual snubbers in i

these categories may be granted by the Commission 'only if justifiable basis for exemption is presented and/or snubber life destructive testing was performed to qualify snubber operabililty for all design conditions at either the completion of their fabrication or at a subsequent date.

PLANT SYSTalS SURVEILLANCE REQUUtE'4ENTS (Continued)

If any snubber selected f or f unct ional testing either f alls to lockup or falls to move, i.e.,

f rocen in place, the cause will be evaluated for f urther action or testing.

d. Ilydraulic Snubbers Functional Test Accep tance Criteria The hydraulic snubber f unctional test shall verif y that:

1.

Activation,(restraining action) is achieved within the specified range of velocity or acceleration in both t ens ion and comp ress ion.

2.

Snubber bleed, or release rate, where required, is within the specif ied range in comp ression or tension.

c. Mechanical Snubbers Functional Test Accep tance Criterta The mechanical snubber f unctional test shall verif y that:

s 1.

The force that initates f ree movement of the snubber rod in either tension or compression is less than the specif led maximum drag f orce.

2.

Activation (restraining action) is achieved in both tension and comp ression.

f. Snubber Se rvice Lif e Monttoring-A record of the se rvice life of each snubber, the date at which the designated service lif e commences and the installation and maintenance records on which the designed service lif e is based shall be maintained as required by Specif ication 6.10.2.m.

Concurrent with the f irst inservice visual inspection and at least once per 18 months thereaf ter, the installation and maintenance records f or each snubber listed in Tables 3.7-2a and 3.7-2b shall be reviewed to verif y that ' the indicated service lif e has not been exceeded or will not be exceeded by more than 10% prior to the next scheduled snubber se rvice lif e review.

If the indicated service lif e will be exceeded by Edre than 107, prior to the next scheduled snubber service life review, the snubber service lHe shall be reevaluated or the snubber shall be replaced or recondit Loned so as to extend its service life beyond the,date of the next scheduled service lite review. The results of the reevaluation may be used to justif y a change to the service, lif e oE/ the snubber. This reevaluation, replacement or reconditioning shall be indicated in the records.

PLANT SYSTEMS BASE 3 3/4.7.7 C NTROL ROOM EMERGENCY VENTILATION SYSTEM (Continued) for operations personnel during and following all credible accident conditions.

The OPERABILITY of this sytem in conjuntion with control room design provisions is based on limiting the radiation exposure to personnel occupying the control room to 5 ren or less whole body, or its equivalent and I

maintaining the chlorine concentration within acceptable limits during and following a chlorine accident This limitation is consistent with the requirements of General Design Criteria 10 of Appendix "A", 10 CFR 50.

3/4.7.8 ECCS AREA VENTILATION SYSTEM The OPERABILITY of the ECCS area ventilation system ersures that radioactive materials leaking from the ECCS equipment following a LOCA are filtered prior to reaching the environment.

The operation of this system and the resultant effect on offsite dosage calculations was assumed in the accident analyses.

f 3/4.7.9 SEALED SOURCE CONTAMINATION The limitatios on sealed source removal contamination ensure that the total body or individual organ irradiation does not exceed allowable limits in the event of ingestion or inhalation of the probable leakage from the source material.

The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium.

Qualities of interest to this specification which are exempt f rca the leakage testing are consistent with the criteria of 10 CFR Parts 30.11-20 and 70.19.

Leakage from sources excluded from the requirements of this specification is not likely to represent nore than one maximum permissible body burden for total body irradiation if the source material is inhaled or ingested.

l 3/4.7.10 SNUBBERS

\\

All snubbers are required to be OPERABLE to ensure that the structural integrity of the reactor coolant system and all other safety related systems is maintained during and following a Geismic or other event initiating dynamic loads.

Snubbers excluded from this inspection program 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 l

safety-related system.

The visual inspection frequency is based upon maintaining a constant l

level of snubber protection to systems.

Therefore, the required inspection interval varies inversely with the observed snubber failures and is determined by the number of inoperable snubbers found during an inspection.

Inspections performed before that interval has elapsed ' may be used as a new reference point to determine the next inspection.

However, the results of such early inspections performed before the original required time interval has elapsed (nominal time less 25%) may not be used to lengthen the required inspection interval.

Any inspection whose results require a shorter inspection interval i

i will override the previous schedule.

_ PLANT SYSTEMS BASES 3/4.7.10 SNUBBERS (Continued)

When the cause of the rejection of a snubber is clearly established and remedied for that snubber and for any other snubber that may be generically susceptible, and verified by inservice functional testing, that snubber may be exempted from being counted as ir. operable.

Generically susceptible snubbers are those which are of a specific make or model and have the same design features directly related to rejection of the snubber by visual inspection, or are similarly located or expased to the saae environmental conditions such as temperature, radiation, and vibration.

When a snubber is found inoperable, an evaluetion is performed, in addition to the determination of the snubber mode of failure, in order to determine if any safety-related component or system has been adversly affected by the inoperability of the snubber.

The engineering evaluation shall determine whether or not the snubber mode of failure has imparted a significant effect or degradation on the supported couponent or system.

To provide assurance of snubber functional reliability, a representative sample of the installed snubbers will be functionally tested during pl tnt shutdowns at 18 month intervals.

Observed failures of these sample snubbers shall require functional testing of additional units.

In cases where the cause of failure has been identitiel, additional snubbers, having a high probability for the same type failure or that are being used in the same application that caused the failure, shall be teted.

Th!s requiroent increases the probability of locating inoperable snubbers without testing 100% of the snubbers.

Hydraulic snubbers and mechanical snub be rs may each be treated as a dif ferent entity for the above surveillance programs.

The se rvice life of a snubber is evaluated via manuf acturer input and information through consideration of the snubber service conditions and associated installation and maintenance records (newly installed snubber, seal replaced, spring replaced, la high radiation area, in high temperature area, etc.

.).

The requirement to monitor the snubber service life is included to ensure that the snubbers periodically undergo a performance evaluation in view of their age and operating conditions.

These records will provide statistical bases for future consideration of snubber service life.

The requirements for the maintenmace of records and the snubber service life review are not intended to affect plant operation.

3/4.7.11 FIRE SUPPRESSION SYSTEMS The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety related equipment is St. Lucie Unit i B 3/4 7-6

PLCT SYSTFI!S BASES 3/4.7.11 FIR E SUPPRESSIO'4 SYSTCTS (Continued) loca ted.

The f tre suppression sys cem consists of the water system and f ice hose stations.

The collective capability of the f re suppression syste=a is adequate to minimize potential damage to saf ety related equipment and is a major element in the f acility fire protection program.

In the event that po rt ions of the ftre supp ress ion systems are inoperabic, alternate backup fire f ighting equipment is required to be made available in the af f ecced areas until th.e inoperable equipment is restored to service.

In the event the ftre s upp ress ion water system becomes inop e rable, immediate corrective measures must be takea since this system provides the major f tre supp ress ion capability of the plant.

The requirements for a twenty-f our hour report to the Commission provides f o r p ro::p t evaluation of the accep tability of the corrective measures to provide adequate ftre suppression capability f or the continued protection of the nuclear platt.

3/4.7.12 PENETRATION FIRE BARRIERS The f unctional integ rity of the penetration fire barreira enaures that fires will be co nf ined or adeauately retarded from spreading to adjancent portions of the Eacility.

This design f eature mininizes the possibility c: a sngle ftre rapidly involving several areas of the f aelity prior to detection and extinguishme nt.

The penetration fire barriers are a passive eleaent in the f acility f tre protection program and are subject to periodic inspections.

During periods of time when the barriers are not intact, routine f tre watch patrols in conjunction with OPERABLE fire detection ialtrumentation or a continuous ftre watch are required to be mainta ined in the vicinity of the af f ected barrier until the barrier is restored to intact status.
