ACTION 1.1 ACTION shall be that part of a Specification which prescribes remedial measures required under designated conditions.
AVERAGE PLANAR EXPOSURE
- 1. 2 The AVERAGE PLANAR EXPOSURE shall be applicable to a specific planar height and is equal to the sum of the exposure of all the fuel rods in the specified bundle at the specified height divided by the number of fuel rods in the fuel bundle.
. AVERAGE PLANAR LINEAR NEAT GENERATION RATE
- 1. 3 The AVERAGE PLANAR LINEAR HEAT GENERATIDH RATE (APLHGR) shall be applicable to a specific planar height and is equal to the sum of the LINEAR MEAT GENERATION RATES for all the fuel rods in the specified bundle at the specified height divided by the number of fuel rods in the fuel bundle.
CHANNEL CALIBRATION 1.4 A CHANNEL CALIBRATION shall be the adjustment, as necessary, of the channel output such that it responds with the necessary range and accuracy to known values of the parameter which the channel monitors. The CHANNEL CALIBRATION shall encompass the entire channel including the sensor and alare and/or f. rip functions, and shall include the CHANNEL FUNCTIONAL TEST. The CHANNEL CALIBRATION may be performed by any series of aequential, overlapping or total channel steps such that the antire channel is calibrated.
CHANNEL CNECK 1.5 A CHANNEL CHECK shall be the qualitative assessment of channel behavior during operation by observation. This determination shall include, where i
possible, comparison of the channel indication and/or status with other indi-cations and/or status derived from independent instrument channels measuring the same parameter.
CHANNEL FUNCTIONAL TEST 1.6 A CHANNEL FUNCTIONAL TEST shall be:
Analog channels - the injection of a simulated signal into the-a.
channel as close to the sensor as practicable to verify OPERABILITY including alars and/or trip functions and channel failure trips.
b.
Bu, table channels - the in.iection of a simuisted signal into the sensor te verify OPERABILITY including alars and/or trip functions.
The CHANNEL FUNCTIONAL TEST may be perfomed by any series of seguential, overlapping or total channel steps such that the entire channel is tested.

PLANT SYSTEMS BASES 3/4.7.4 SNUBBERS (Continued)
The acceptance criteria are to be used in the visual inspection to determine OPERABILITY of the snubbers.
For example, if a fluid port of a hydraulic snubber is found to be uncovered, the snubber shall be declared inoperable and shall not be determined OPERABLE via functional testing.
l To provide assurance of snubber functional reliability one of three functional testing methsds is used with the stated acceptance criteria:
1.
Functionally test 10% of a type of snubber with an additional 5%
l l
tested for each functional testing failure, or 2.
Functionally test a sample size and determine sample acceptance or rejection using Figure 4.7.4-1, or 3.
Functionally test a representative sample size and determine sample acceptance or rejection using the stated equation.
Figure 4.7.4-1 was developed using "Wald's Sequential Probability Ratio Plan" described in " Quality Control and Industrial Statistics" by Acheson J. Duncan.
Permanent or other exemptions from the surveillance program for individual snubbers may be granted by the Commission if a justifiable basis for exemption is presented and, if applicable, snubber life destructive testing was performed to qualify the snubbers for the applicable design conditions at either the completion of their fabrication or at a subsequent 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 asso-ciated installation and maintenance records (newly installed snubber, seal replaced, spring replaced, in 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.
3/4.7.5 SEALED SOURCE CONTAMINATION The limitation on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium.
This limitation will e% ure that leakage from byproduct, source, and special nuclear material sources will not exceed allowable intake values.
Scaled sources are classified into three groups according to their use, with surveillance requirements commensurate with the probability of damage to a source in that group.
Those sources which are frequently handled are required to be tested more often than those which are not.
Sealed sources which are continuously enclosed within a shicided mechanism, i.e., sealed sources within radiation monitoring or boron measuring devices, are considered to be stored and need not be tested unless they are removed from the shielded mechanism.
GRAND GULF-UNIT 1 B 3/4 7-3 Amendment No.35 l
______-__a
f PLANT SYSTEMS BASES 3/4.7.6 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 located.
The fire suppression system consists of the water system, spray and/or sprinklers, CO2 systems, halon systems and fire hose stations.
The collective capability of 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 until the inoperable equipment is restored to service. When the inoperable fire fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate
~'means of fire fighting than if the inoperable equipment is the primary means of fire suppression.
The surveillance requirements provide assurances that the minimum OPERABILITY requirements of the fire suppression systems are met.
An allowance is made for ensuring a sufficient volume of halon in the belon storage tanks by verifying the weight and pressure of the tanks.
In the event the fire suppression water system becomes inoperable, immediate corrective measures must be taken since this system provides the major fire suppression capability of the plant.
The surveillance requirements for spray and sprinkler systems provide for periodic visual inspections to ensure that temporary structures / objects do not impair the spray patterns which have been established in accordance with the GGNS fire protection design requirements.
3/4.7.7 FIRE RATED ASSEMBLIES The OPERABILITY of the fire barriers and barrier penetrations ensure that fire damage will be limited.
These design features minimize the possibility of a single fire involving more than one fire area prior to detection and extinguishment.
The fire barriers, fire barrier penetrations for conduits, cable trays and piping, fire windows, fire dampers, and fire doors are periodically inspected to verify their OPERABILITY.
3/4.7.8 AREA TEMPERATURE MONITORING The area temperature limitations ensure taat safety-related equipment will not be subjected to temperatures in excess of their environmental qualification temperatures.
Exposure to excessive temperatures may degrade equipment and can cause loss of its OPERABILITY. The temperature limits include allowance for instrument error.
GRAND GULF-UNIT 1 B 3/4 7-4
PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) e.
Functional Tests During the first refueling shutdown and at least'once per 18 months thereafter during shutdown, a representative sample of snubbers shall be tested using one of the following sample plans for each type of snubber. The sample plan shall be selected prior to the test period j
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 meet the functional test acceptance criteria of Specification 4.7.4.f, an additional 5% l 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 func-tionally tested in accordance with Figure 4.7.4-1.
"C" is the total number of snubbers of a type found not meeting the accept-ance requirements of Specification 4.7.4.f.
The cumulative num-ber 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 plus current day's increments) shall be plotted on i
Figure 4.7.4-1.
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 plutted 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; or 3)
An initial representative sample of 55 snubbers shall be func-tionally 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 be tested until the total number tested is equal to the initial sample size multi-plied by the factor, 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 "Ac-cept" 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 on or below the " Accept" line, testing of that type of snubber may be terminated.
If the point plotted falls above the " Accept" line, testing must continue until the point falls in the " Accept" region or all the snubbers of that j
type have been tested.

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)
Testing equipment failure during functional testing may invalidate that day's testing and allow that day's testing to resume anew at a l
later time, providing all snubbers tested with the failed equipment q
during the day of equipment failure are retested. The representative sample selected for the functional test sample plans shall be ran'domly 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 environ-ments,-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 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 j
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 l
The snubber functional test shall verify that:
1)
Activation (restraining action) is ach'ieved within the specified-I 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; j
3)
For mechanical snubbers, the force required to initiate or main-tain 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.
Testing metho'ds 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.
j 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 detemine 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 l
be performed on the components to which the inoperable snubbers are j
attached. The purpose of this engineering evaluation shall be to deter-j mine if the components to which the inoperable snubbers are attached were adversely affected by the inoperability of the snubbers in order to ensure that the component remains capable of meeting the designed service.
