3/4'.I.5 SNUBBERS s

LIMITING CONDITION FOR OPERATION

=

3.7.5 All hydraulic and mechanical snubbers shall be OPERABLE.

APPLICABILITY: OPERATIONAL CONDITIONS 1, 2, and 3.

OPERATIONAL CONDITIONS 4 and 5 for snubbers located on systems required OPERABLE in those OPERATIONAL CONDITIONS.

ACTION:

With one or more snubbers inoperable on any system, 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 an' perform an engineering evaluation per Specification 4.7.5.g on the attached component or declare the attached system inoperable and follow the appropriate ACTION statement for that system.

SURVEILLANCE REQUIREMENTS 4.7.5 Each snubber shall be demonstrated OPEP.A3LE 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 manufacturer, irrespective of capacity.

b.

Visual Inspections Snubbers are categorized as inaccessible or accessible during reactor operation. Each of these groups (inaccessible and accessible) may be inspected independently according to the schedule below. 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 hydraulic and mechanical snubbers.

If all snubbers of each type on any system are found OPERABLE during the first inservice visual inspection, the second inservice visual inspection of that system shall be performed at the first refueling outage.

Otherwise, subsequent visual inspections of a given system shall be performed in accordance with the following schedule:

Visual Inspection Acceptance Criteria Visual inspections shall verify that:

(1) there are no visible indications of damage or impaired OPERABILITY, (2) attachments to the foundation or support structure are secure, and (3) fasteners for attachment of the snubber to the component and to the snubber anchorage are secure.

Snubbers which appear inoperable as a result of visual inspections may be determined OPERABLE for the purpose of establishing the next visual inspection interval, provided that:

(1) the cause of the rejection is clearly established and remedied for that particular snubber and for other snubbers irrespective of type on that system that may be generically susceptible; and (2) the affected snubber is functionally tested in the as-found condition and determined OPERABLE per Specifications 4.7.5.f.

All snubbers connected to an inoperable common hydraulic fluid reservoir shall be counted as inoperable snubbers. For those snubburs common to more than one system, the OPERABILITY of such snubbers shall be considered in assessing the surveillance schedule for each of the related systems.

d.

Transient Event Inspection An inspection shall be performed of all hydraulic and mechanical snubbers attached to sections of systems that have experienced unexpected, potentially damaging transients as determined from a review of operational data and a visual inspection of the systems within 6 months following such an event.

In addition to satisfying the visual inspection criteria, freedom-of-motion of mechanical snubbers shall be verified using at least one of the following:

(1) manually induced snubber movement; or (2) evaluation of in place snubber piston setting; or (3) stroking the mechanical snubber through its full range of travel.

l The inspection interval for each type of snubber on a given system 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 step the first time and two steps thereafter if no inoperable snubbers of that type are found on that system.

The provisions of Specification 4.0.2 are not applicable.

.v SURVEILLANCE REQUIREMENTS (Continued) e.

Functional Tests

^

During the first refueling shutdown and at least once pe? 18 months thereafter during shutdown, a representative sample of snubbers shall be tested using one of the following sample plans. The sample plan shall be selected prior to the test period and cannot be changed during the test period. The NRC Regional Administrator shall be notified in writing of -the sample plan selected prior to the test period or the sample plan used in the prior test period shall be implemented:

1) At least 10% of the total of each type of snubber shall be functionally tested either in-place or in a bench test. For each snubber of a type that does not meeting the functional test acceptance criteria of Specification 4.7.5.f. an additional 10% of that type of snubber shall be functionally tested until no more failures are found or until all snubbers of that type have been functionally tested; or

2) A representative sample of each type of snubber shall be functionally ' tested in accordance with Figure 4.7.5-1.

"C" is the total number of snubbers of a type found not meeting the acceptance i

requirements of Specification 4.7.5.f.

The cumulative number of snubbers of a type tested is denoted by "N."

At the end of each day's testing, the new values of "N" and "C" (previous day's total pies current day's increeents) shall be plotted on Figuro 4.7.5-1.

If at any time the point plotted falls in the " Reject" region all snubbers of that type shall be functionally tested.

If at any time the point plotted falls in the " Accept" region, testing of snubbers of that type may be terminated. When the point plotted lies in the " Continue Testing" region, additional snubbers of that type shall be tested until the point falls in the " Accept" region or the " Reject" region, or all the snubbers of that type have been tested. Testing equipment failure during functional testing may invalidate that day a testing and allow that day's testing to resume anew at a later time, providing all snubbers tested with the failed equipment during a day of equipment failure are retested.

3) An initial representative sample of 55 anubbers shall be functionally tested. For each snubber type which does not meet the functional test acceptance criteria, another sample of at least one-half the size of the initial sample shall to tested until the total number tested is equal to the initial sample size multiplied by the f actor,1 + C/2, where "C" is the number of snubbers found which do not meet the functional test acceptance criteria. The results from this sample plan shall be plotted using an " Accept" line which follows the equation N = 55(1 + C/2).

Each snubber point should be plotted as soon as the snubber is tested.

If the point plotted falls above the " Accept" line, testing must continue i

until the point falls in the " Accept" region or all the snubbers of that type have been tested.

BRUNSWICK - UNIT 1 3/4 7-11 Amendment No.

(BSEP-1-04)

PLANT SYSTEMS SURVEILbANCEREQUIREMENTS(Continued)

The representative sample selected for the functional test sample plans shall be randomly selected from the snubbers of each type and reviewed before beginning the testing. The review shall ensure as.far as practical that they are representative of the various configurations, operating environments, range of size, and capacity of snubbers of each

' type. Snubbers placed in the same locations as snubbers which failed the previous functional test shall be retested at the time of the next functional test but shall not be included in the rample plan.

If

, during the functional testing, additional sampling is required due to failure of only one type of snubber, the functional testing results shall be reviewed at the time to determine if additional samples should be limited to the type of snubber which has failed the functional testing.

[

f.

Functional Test Acceptance Criteria The snubber functional test shall verify that:

1) Activation (restraining action) is achieved within the specified range in both tension and compression;

2) Snubber bleed, or release rate where required, is present in both tension and compression, within the specified range;

3) Where required, the force required to initiate or maintain motion of the snubber is within the specified range in both directions of travel; and

4) For snubbers specifically required not to displace undce continuous load, the ability of the snubber to withstand load without displacement.

Testing methods may be used to measure parameters indirectly or parameters other than those specified if those results can be correlated to the specified parameters through established methods.

g.

Functional Test Failure Analysis An engineering evaluation shall be made of each failure' to meet the functional test acceptance criteria tu determine the cause of the failure. The results of this evaluation shall be used, if applicable, in selecting snubbers to be tested in an effort to determine the OPERABILITY of other snubbers irrespective of type which may be subject to the same failure mode.

For the snubbers found inoperable, an engineering evaluation shall be performed on the components to which the operable snubbers are attached. The purpose of this engineering evaluation shall be to determine if the components to which the inoperable snubbers are attached were adversely affected by the operability of the snubbers in order to ensure that the component remain 9 capable of meeting the designed service.

BRUNSWICK - UNIT 1 3/4 7-12 Amendment No.

o (BSEP-1-04)

PLANT SYSTEMS

_ SURVEILLANCE REQUIREMENTS (Continued) '

If any snubber selected for functional testing either fails to lock up or f ails to move, i.e., frozen-in place, the cause will be evaluated and if caused by manufacturer or design deficiency all snubbers of the same type subject to the same defect shall be functionally tested.

This testing requirement shall be independent of the requirements stated in Specification 4.7.5.e for snubbers not meeting the functional test accepeance criteria.

h[ Functional Testing of Repaired and Replaced Snubbers Snubbe"s which fail the visual inspection or the functional test acceptence criteria shall be repaired or replaced. Replacement snubbers and snubbers which have repairs which might affect the functional test result shall le tested to meet the functional test criteria before installation in the unit. Mechanical snubbers shall have met the acceptance criteria subsequent to their most recent service, and the freedom-of-motion test must have been performed within 12 months before being installed in the unit.

j

i. Snubber Seal Replacement Program The service life of hydraulic and mechanical snubbers shall be monitored to ensure that tha service life is not exceeded between surveillance inspections. The maximum expected service life for various seals, springs, and other critical parts shall be determined and established based on engineering information and shall be extended or shortened based on monitored test results and failure history.

Critical parts shall be replaced so that the maximum service life will not be exceeded during a period when the snubber is required to be OPERABLE. The parts replacements shall be documented and the documentation shall be retained in accordance with Specification 6.10.2.

In order to establish the inspection frequoney for each type of snubber on a safety-related system, it was assumod that the frequency of snubbor failures and initiating events are constant with timo and that the failure of any snubber on that system could i

cause the system to be unprotected and to result in failures during an assumed initiating event.

Inspections performed before that interval has olapsed may be used as a now reference point to dotermino the next inspection.

However, the result of such early inspections performod before the original required time interval has elapsed (nominal timo loss 25%) may not be used to longthon the roquired inspection interval. Any inspection whose results toquiro a shorter inspection interval will overrido the previous scheduto.

The requir1 ment to monitor the snubber service life is included to t

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.

3/4.7.6 SEALED SOURCE CONTAMINATION i

The limitations on sealed source removable contamination ensure that the total body or individual organ irradiation does not exceed allowable limits in the event of ingestion or inhalation of the source material. The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 79.39(c) limits for plutonium.

Quantities of interest to this specification which are exempt from the Icakage testing are consistent with the criteria of 10 CFR Part 30.11-20 and 70.19.

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

3/4.7.7 FIRE SUPPRESSION SYSTEMS s

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 located. The fire suppression system consists of the water system, spray and/or sprinklers, CO, and fire hose stations. The collective capability of 2

the fire suppression systems is adequate to minimize potential damage to l

safety-related equipment and is a major element in the facility fire protection program.

j In the event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas until the inoperable equipment is restored to service.

In the event the fire suppression water system become inoperable, immediate corrective measures must be taken since this system provides the major fire suppression capability of the plant.

The requirement for a 24-hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provide adequate fire suppression capability for the continued protection of the nuclear plant.

sample plan used in the prior test period shall be implemented:

1

1) At least 10% of the total of each type of snubber shall be f

j functionally tested either in-place or in a bench test. For each snubber of a type that does not meeting the functional test j

acceptance criteria of Specification 4.7.5.f, an additional 10% of that type of snubber shall be functionally tested until no more i

j failures are found or until all snubbers of that type have been l

j functionally tested; or 1

i

2) A representative sample of each type of snubber shall be functionally tested in accordance with Figure 4.7.5-1.

"C" is the l

total number of snubbers of a type found not meeting the acceptance

{

requirements of Specification 4.7.5.f.

The cumulative number of j

l snubbers of a type tested is denoted by "N."

At the end of each i

day's testing, the new values of "N" and "C" (previous day's total

[

plus current day's increments) shall be plotted on Figure 4.7.5-1.

If at any time the point plotted falls in the " Reject" regior all snubbers.of that type shall be functionally tested.

If i

I

'at any time the point plotted falls in the " Accept" region, testing of snubbers of that type may be terminated. When the point plotted i

type shall be tested until the point falls in the " Accept" region or the " Reject" region, or all the snubbers of that type have been l

tested. Testing equipcent failure during functional testing may l

invalidate that day's testing and allow that day's testing to resume anew at a later time, providing all snubbers tested with the failed equipment during a day of equipment failure are retested.

I PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

The representative sample selected for the functional test sample plans shall be randomly selected from the snubbers of each type and reviewed before beginning the testing.

The review shall ensure as far as practical that they are representative of the various configurations, operating environments, range of size, and capacity of snubbers of each type. Snubbers placed in the same locations as snubbers which failed the previous functional test shall be retested at the time of the next functional. 4est but shall not be included in the sample plan.

If during the functional testing, additional sampling is required due to failure of only one type of snubber, the functional testing results shall be reviewed at the time to determine if additional samples should be limited to the type of snubber which has failed the functional testing.

f.

Functional Test Acceptance Criteria The snubber functional test shall verify that:

1) Activation (restraining action) is achieved within the specified range in both tension and compression;

2) Snubber bleed, or release rate where required, is present in both tension and compression, within the specified range;

3) Where required, the force required to initiate or maintain motion of the snubber is within the specified range in both directions of travel; and

4) For snubbers specifically required not to displace under continuous load, the ability of the snubber to withstand load without displacement.

i Testing methods may be used to measure parameters indirectly or parameters other than those specified if those results can be correlated to the specified parameters through established methods.

I g.

Functional Test Failure Analysis An engineering evaluation shall be made of each failure to meet the functional test acceptance criteria to determine the cause of the failure.

The results of this evaluation shall be used, if applicable, in selecting snubbers to be tested in an effort to determine the OPERABILITY of other snubbers irrespective of type which may be subject i

to the same failure mode.

For the snubbers found inoperable, an engineering evaluation shall be i

_ PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

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 snubbers of the same type subject to the same defect shall be functionally tested.

This testing requirement shall be independent of the requirements stated in Specification 4.7.5.e for snubbers not meeting the functional test acceptance criteria.

h.

Functional Testing of Repaired and Replaced Snubbers Snubbers which fail the visual inspection or the functional test acceptance criteria shall be repaired or replaced.

Replacement snubbers and snubbers which have repairs which might affect the functional test result shall be tested to meet the functional test criteria before installation in the unit. Mechanical snubbers shall have met the acceptance criteria subsequent to their most recent service, and the freedom-of-motion test must have been performed within 12 months before being installed in the unit.

i. Snubber Seal Replacement Program The service life of hydraulic and mechanical snubbers shall be monitored to ensure that the service life is not exceeded between surveillance inspections. The maximum expected service life for various seals, springs, and other critical parts shall be determined and established based on engineering information and shall be extended or shortened based on monitored test results and failure history.

Critical parts shall be replaced so that the maximum service life will not be exceeded during a period when the snubber is required to be OPERABLE.

The parts replacements shall be documented and the documentation shall be retained in accordance with Specification 6.10.2.

l BAS.3 3/4.7.4 REACTOR CORE ISOLATTDN COOLING SYSTE!! (Continued)

RCICS specifications are applicable during CONDITIONS 1, 2, and 3 when reactor vessel pressura exceeds 113 psig because RCICS is the primary non-ECCS source of emergency core cooling when the reactor is pressurized.

With RCISS inoperable, adequate core cooling is assured by the demonstrated OPERABILITY of the llPCIS system and justifies the specified out-of-service period.

The surveillance requirements provide adequate assurance that RCICS and the condensate storage tank will be OPERABLE when required. Although all active components are testable and full flow can be demonstrated by recirculation during reactor operation, a complete functional test requires reactor shutdown. The pump discharge piping is maintained full to provent water hammer damago and to start cooling at the earliest moment.

3/4.7.5 SNUBBERS All snubbers are required OPERABLE to ensure that the structural integrity of the Reactor Coolant System and all other safety-rolated systems is maintained during and following a noismic or other event initiating dynamic loads. Snubbers excluded from this inspection program are those installed on nonsafety-related uystems and then only if their failure or failure of the systems which they are installed, would have no adverse effect on any safety-related system.

Snubbers are classified and grouped by design and manufacturer but not by size. For examplo, mechanical snubbers utilizing the same design features of the 2-kip,10-kip, and 100-kip capacity manuf actured by Company "A" are of the same type. The same design mechanical anubbers manufactured by Company "B" for the purposos of this Technical Specification would be of a different type, as would hydraulic snubbers from either manufacturer.

A list of individual snubbers with detailed information of snubber location and size and of system affected shall be availablo at the plant in accordaneo with Section 50.71(c) of 10 CFR Part 30. The accessibility of each snubber shall be determined and approved by the Plant Nuctoar Safety Commi t tee.

The determination shall be based upon tho existing radiation levels and the expected time to perform a visual inspection in each snubber location as woll as other factors associated with accessibility during plant operations (e.g., temperaturo, atmosphere, locations, etc.), and the recommendations of Regglatory Guides 8.8 and 8.10.

The addition or deletion of any hydraulic or mechanical anubber shall be madu in accordance with Section 50.59 of 10 CFR Part $0.

SNUBBERS (Continued)

[

t The visual inspection frequency is based upon maintaining a constant i

lest of snubber protection to each safety-related system. Therefore, the required inspection interval varies inversely with the observed snubber failures on a given system and is determined by the number of inoperable snubbers found during an inspection of each system.

In order to establish the inspection frequency for each type of snubber on a safety-related system, it was assumed that the frequency of snubber failures and initiating events are constant with time and that the failure of any snubber on trat system could i

cause the system to be unprotected and to result in failures during an assumed

{

initiating event.

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

However, the result of such early inspections performed before the original required i

i time interval has elapsed (nominal time less 25%) may not be used to lengthen the required inspection interval. Any inspection whose results require a i

shorter inspection interval will override the previous schedule.

j The acceptance criteria are to be used in the visual inspection to l

determine OPERABILITY of the snubbers. For example, if a fluid port of a hydraulic anubber is found to be uncovered, the snubber shall be declared i

inoperable and shall not be determined OPERABLE via functional testing.

To provide assurance of snubber functional reliability one of three functional testing methods are used with the stated acceptance criterlat 1.

Functionally test 10% of a type of snubber with an additional 10%

tested for each functional testing failure, or 2.

Functionally test a sample size and determino sample acceptance or l

rejection using Figure 4.7.5-1, or

(

3.

Functionally test a representative sample size and determino sample i

acceptance or rejection using the stated equation.

Figure 4.7.5-1 was developed using "Wald's Sequential Probability Ratio Plan" as described in " Quality Control and Industrial Statistics" by Acheson J. Duncan.

Fermanent or other oxomptions from the surveillance program for individual snuhbers may be granted by the Commission if a justifiable basis for exemption is presented and, if applicablo, snubber life destructive t

testing was performed r,p qualify the snubbers for the applicablo design l

conditions at either the complation of their fabrication or at a subsequent i

l date.

Snubbers so exempted shall be listed in the list of individual snubbers indicating the extent of the exemptions.

The service life of a snubber is established via manufacturer input and~information through consideration of the snubber service conditions and associated installation and maintenance records (newly installed snubber, seal replaced, spring replaced, in high radiation area, in high temperature area, etc.).

The roquirement 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 basas for future consideration of snubber service life.

3/4.7.6 SEALED SOURCE CONTAllINATION The limitations on sealed source removable contamination ensure that the total body or individual organ irradiation does not exceed allowable limits in the event of ingestion or inhalation of the source material. The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 79.39(c) limits for plutonium.

Quantities of interest to this specification which are exempt from the leakage testing are consistent with the criteria of 10 CFR Part 30.11-20 and 70.19.

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

3/4.7.7 FIRE SUPPRESSION SYSTE?tS The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confino and extinguish fires occurring in any portion of the facility where esfoty-related equipment is located. The fire suppression system consists of the water system, spray and/or sprinklers, CO, and fire hose stations. The collective capability of 2

the fire suppression systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility fire protection program.

In the event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas untti the inoperable equipment is restored to service.

In the event the fire suppression water system become inoperable, immediate correctivo measures must be taken since this system provides the majorfiresuppressioncapagilityoftheplant. The requirement for a 24-hour report to the Commission provides for prompt evaluation of the acceptability of the corrective measures to provido adequate fire suppression capability for a

the continued protection of the nuclear plant.

PLANT SYSTEMS BASES-(Continued) 3/4.7.8 FIRE BARRIER PENETRATIONS j

The functional integrity of the fire barrier penetrations ensures that fires will be confined or adequately retarded from spreading to adjacent potions of the facility. This design feature minimizes the possibility of a single fire rapidly involving several areas of the facility prior to detection and extinguishmenty-The fire barrier penetrations are a passive element in the facility fire protection programs and are subject to periodic inspections.

The barrier penetrations, including cable-penetration barriers, fire doors, and dampers, are considered functional when the visually observed condition is the same as the as-designed condition. For those fire barrier penetrations that are not in the as-designed condition, an evaluation shall be i

performed to show that the modification has not degraded the fire rating of I

the fire barrier penetration.

During periods of time when the barriers are not functional, either

1) a continuous fire watch is required to be maintained in the vicinity of the 4

affected barrier, or 2) the fire detectors on at least one side of the affected barrier must be verified OPERABLE and a hourly fire watch patrol established until the barrier is restored to functional status.
