j COMMITMENTS:

Radioactive wastes shall be solidified or dewatered in accordance with the PROCESS CONTROL PROGRAM to meet shipping and transportation requirements during transit, and disposal site requirements when received at the disposal site.

APPLICABILITY: At all times REMEDIAL ACTION:

a) With SOLIDIFICAIOTN or dewatering not meeting disposal site and shipping and transportation requirements, suspend shipment of inadequately processed wastes and correct the PROCESS CONTROL PROGRAM, the procedures and/or the Solid Waste System as j necessary tc prevent recurrence.

b) With SOLIDIFICATION or dewatering not performed in accordance l with the PROCESS CONTROL PROGRAM, test the improperly processed waste in each container to ensure that it meets burial ground and j shipping requirements and take appropriate administrative action i

to prevent recurrence.

\_-

TESTING REQUIREMENTS:

SOLIDIFICATION of at least one representative test specimen from at least every tenth batch of each type of wet radioactive wastes (e.g.,

fi]ter sludges, spent resins, evaporator bottoms, boric acid solutions and sodium sulfate solutions) shall be verified in accordance with the PROCESS CONTROL PROGRAM:

a) If any te.t specimen fails to verify SOLIDIFICATION, the SOLIDIFICATION of the batch under test shall be suspended until such time as additional test specimens can be obtained, alternative SOLIDIFICATION parameters can be determined in accordance with the PROCESS CONTROL PROGRAM, and a subsequent test verifies SOLIDIFICATION. SOLIDIFICATION of the batch may then be resumed using the alternative SOLIDIFICATION parameters determined by the PROCESS CONTROL PROGRAM; 16.11-44

For the 15 minute period during which simultaneous Centrifugal Charging pump operation is allowed, the safety margins as related to the mass addition analysis are not appreciably reduced. ITS 3.4.12 requires two PORVs (or equivalent) to be operable during this period of operation, j thus a mass addition transient can be relieved as required assuming the two PORVs (or equivalent) function properly.

[O s

SLC 16.15-3.1.2.3 required one charging pump in the boration flow path of SLC 16.15-3.1.2.1 to be OPERABLE and capable of being powered from an OPERABLE emergency power source. SLC 16.15-3.1.2.3 is applicable in MODES 5 and 6.

The ACTION statement requires ' suspend all operations involving CORE ALTERATIONS or positive reactivity changes.' The intent is that j I

specific evolutions or operations that involve positive reactivity changes (fuel movement, dilutions, control rod movements or sustained NC temperature changes adding positive reactivity) not continue if the conditions described above do not exist. There are operations (e.g.

swapping ND trains, swapping KC trains, some testing) that can result in temperature oscillations that have insignificant effects on shutdown margin and can continue.

Operational or testing activities that result in NC temperature swings of 20'r about an initial value have been judged not to constitute positive reactivity changes as intended in SLC 16.15-3.1.2.3 when in MODE 5. There must be at least 500 ppm of boron beyond,the required Shutdown Boron Concentration for this interpretation to remain valid.

This interpretation should not be used to establish sustained NC s'; stem heatups or cooldowns that result in sustained positive reactivity additions.

COMMITMENT:

1 The radiation monitoring instrumentation channels for plant operations shown in l Table 3.3-6 shall be OPERABLE with their Alarm / Trip Setpoints within the I specified limits.

APPLICABILITY: As shown in Table 3.3-6.

REMEDIAL ACTION:

a. With a radiation monitoring channel Alarm / Trip Setpoint exceeding the value shown in Table 3.3-6, adjust the Setpoint to within the limit within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or declare the channel inoperable,

b. With one or more radiation monitoring channels inoperable, take the action shown in Table 3.3-6.

l TESTING REQUIREMENTS:

16.15-4.3.3.1 Each radiation monitoring instrumentation channel for plant operations shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL CALIBRATION and ANALOG CHANNEL OPERATIONAL TEST operations for the modes and at the frequencies

( shown in Table 4.3-3.

The OPERABILITY of the radiation monitoring instrumention for plant operations ensures that: (1) the associated action will be initiated with the radiation level monitored by each channel or combination thereof reaches its Setpoint, (2) the specified coincident logic is maintained, and (3) sufficient redundancy is maintained to permit a channel to be out-of-service for testing or maintenance.

The radiation monitors for plant operations senses radiation levels in selected plant systems and locations and determines whether or not predetermined limits are being exceeded, If they are, the signals are combined into logic matrices sensitive to combinations indicative of various accidents and abnormal conditions. Once the required logic combination is completed, the system sends actuation signals to initiate alarms or automatic isolation action and actuation of Emergency Exhaust or Ventilation Systems.

16.15-3.4.2.1 REACTOR COOLANT SYSTEM SAFETY VALVES -SHUTDOWN COMMITMENT:

A minimum of one pressurizer Code safety valve shall be OPERABLE with a lift setting setting of 2485 psig + 3%, -2%*.

APPLICABILITY: MODES 4 and 5.

REMEDIAL ACTION:

With no pressurizer Code safety valve OPERABLE, immediately suspend all operations involving positive reactivity changes and place an OPERABLE RHR loop into operation in the shutdown cooling mode.

TESTING REOUIREMENTS:

16.15-4.4.2.1 No additional requirements other than those required by Specification 5.5.8. Following testing, lift settings shall be within + 1%.

BASES:

The pressurizer code safety valves operate to prevent the RCS from being pressurized above its Safety Limit of 2735 psig. Each safety valve is designed

/

,_s to relieve 420,000 lbs per hour of saturated steam at the valve Setpcint. The

) relief capacity of a single safety valve is adequate to relieve any overpressure

\,,/ condition which could occur during shutdown. In the event that no safety valves are OPERABLE, an operating RHR loop, connected to the RCS, provides overpressure relief capability and will prevent RCS overpressurization. In addition, the Overpressure Protection System provides a diverse means of protection against RCS overpressurization at low temperatures.

Demonstration of the safety valves' lift settings will occur only during shutdown and will be performed in accordance with the provisions of Section XI of the ASME Boiler and Pressure Code. SLC 16.15-3.4.2.1 & ITS 3.4.10 allow a

+

3% and - 2% setpoint tolerance for OPERABILITY; however, the valves are reset to + 1% during surveillance testing to allow for drift. [

• The lift setting pre .re shall correspond to ambient conditions of the valve at nominal operating temperature and pressure.

The Reactor Coolant System chemistry shall be maintained within the limits specified in Table 3.4-2.

-APPLICABILITY: At all times.

REMEDIAL ACTION:

MODES 1, 2, 3, and 4:

a. With any one or more chemistry parameter in excess of its Steady State Limit but within its Transient Limit, restore the parameter to within its Steady-State Limit within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or Oe in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN w1?hin the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />; and

b. With any one or more chemistry parameter in excess of its Transient Limit, be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

At All Other Times:

With the concentration of either chloride or fluoride in the Reactor l

I O Coolant System in excess of its Steady-State Limit for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or in excess of its Transient Limit, reduce the pressurizer pressure to less than or equal to 500 psig, if applicable, and perform an engineering evaluation to determine the effects of the out-of-limit condition on the structural integrity of the Reactor Coolant System; determine that the Reactor Coolant System remains acceptable for continued operation prior to increasing the pressurizer pressure above 500 psig or prior to proceeding to MODE 4.

TESTING REQUIREME!1TS:

16.15-4.4.7 The Reactor Coolant System chemistry shall be determined to be within the limits by analysis of those parameters at the frequencies specified in Table 4.4-3.

BASES:

The limitations on Reactor Coolant System chemistry ensure that corrosion of the Reactor :oolant System is minimized and reduces the potential for Reactor Coolant System leakage or failure due to stress corrosion. Maintaining the chemistry within the Steady State Limits provides adequate corrosion protection to ensure the structural integrity of the Reactor Coolant System over the life of the plant. The associated effects of exceeding the oxygen, chloride, and fluoride limits are' time and temperature dependent. Corrosion studies show that l

l 16.15-23 j l

4/99 I

('~'g operation may be continued with contaminant concentration levels in excess of {

l ( ,/ the Steady State Limits, up to the Transient Limits, for the specified limited time intervals without having a significant effect on the structural integrity 1 of the Reactor Coolant System. The time interval permitting continued operation

! within the restrictions of the Transient Limits provides time for taking corrective actions to restore the contaminant concentrations to within the Steady State Limits.

I The Surveillance Requirements provide adequate assurance that concentrations in l excess of the limits will be detected in sufficient time to take remedial l 1 ACTION.

l

2. Verifying flow through the reactor vessel head vent paths during venting during COLD SHUTDOWN or RETJELING.

BASES:

Reactor Vessel Head Vents are provided to exhaust noncondensible gases and/or steam from the primary system that could inhibit natural circulation core ,

cooling. The OPERABILITY of at least one reactor coolant system vent path from the reactor vessel head and the pressurizer steam space ensures the capability exists'to perform this function. (Operability of the pressurizer steam space vent path-is provided by ITS 3.4.11 and 3.4.12).

l The valve redundancy of the reactor coolant system vent paths serves to minimize the probability of inadvertent or irreversible actuation while ensuring that a

- single failure of a vent valve, power supply or control system does not prevent isolation of the vent path.

1 TESTING REQUIREMENTS:

16.15-4.7.8 Each snubber shall be demonstrated OPERABLE by performance of the following augmented inservice inspection program.

I 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 l

Snubbers are categorized as inaccessible or accessible during reactor operation and may be treated independently. 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 i each category of snubber shall be determined based upon the criteria l 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. 126.

Snubbers may be categorized, based upon their accessibility during power operation, as accessible or inaccessible. The categories may be examined separately or jointly. However, the licensee must make and document that decision before any inspection and shall use that decision as the basis upon which to determine the next inspection interval for that category.

Note 2: Interpolation between population or category size and the number of unacceptable snubbers is permissible. Use next lower integer for the value of the limit for Columns A, B, or C if that integer includes a fractional value of unacceptable snubbers as described by interpolation.

16.15-40 4/99

Note 3: If the number of unacceptable snubbers is equal to or less than the y number in Column A, the next inspection interval may be twice the previous interval but not greater than 48 months.

Note 4: If the number of unacceptable snubbers is equal to or less than the number in Column B but greater than the number in Column A, the next inspection shall be the same as the previous interval.

Note 5: If the number of unacceptable snubbers is equal to or greater than the number in Column C, the next inspection interval shall be two-thirds of the previous interval. However, if the number of unacceptable snubbers is less than the number in Column C but greater than the number in Column B, the next interval shall be reduced proportionally by interpolation, that is, the previous interval shall be reduced by a factor that is one third of the ratio of the difference between the number of unacceptable snubbers found during the previous interval and the number in Column B to the difference in the numbers in Columns B l and C. 1 Note 6: The provisions of SLC 16.2.7 are applicable for all inspection intervals up to and including 48 months.

c. Refueling Outace Inspections At e ih refueling, the systems which have the potential for a severe dyr c event, specifically, the main steam system (upstream 'of the mai , team isolation valves) the main steam safety and power-operated re f valves and piping, auxiliary feedwater system, main steam supply

[,, ) to . e auxiliary feedwater pump turbine, and the letdown and charging

\s / portion of the CVCS system shall be inspected to determine if there has been a severe dynamic event. In case of a severe dynamic event, mechanical snubbers in that system which experienced the event shall be inspected during the refueling outage to assure that the mechanical snubbers have freedom of movement and are not frozen up. The inspection shall consist of verifying freedom of motion using one of the following: (1) manually induced snubber movement; (2) evaluation of in-place snubber piston setting; (3) stroking the mechanical snubber through its full range of travel. If one or more mechanical snubbers are found to be frozen up during this inspection, those snubbers shall be replaced or repaired before returning to power. The requirements of SLC 16.15-4.7.8b are independent of the requirements of this SLC.

d. Visual Inspection Acceptance Criteria Visual inspections shall verify: (1) that there are no visible indica-tions of damage or impaired OPERABILITY, and (2) attachments to the foundation or supporting structure are secure. Snubbers which appear inoperable as a result of visual inspections "shall be classified as unacceptable and may be reclassified acceptable" for the purpose of establishing the next visual inspection interval, 16.15-41 O

V 4'99

provided that: (1) the cause of the rejection is clearly established and remedied for that particular snubber and for other snubbers irrespective of type that may be generically susceptible; and (2) the affected snubber is functionally tested in the as found condition and determined OPERABLE per SLC 16.15-4.7.8f. A hydraulic snubber found )

with the fluid port uncovered and all hydraulic snubbers found connected to an inoperable common reservoir shall be classified as unacceptable and may be reclassified acceptable by functionally testing each snubber starting with the piston in the as-found setting, extending the piston rod in the tension direction.

e. Functional Tests During the first refueling shutdown and at least once per refueling thereafter, a representative sample of snubbers shall be tested using one of the following sample plans. The large bore steam generator hydraulic snubbers shall be treated as a separate population for func-tional test purposes. A 10% random sample from previously untested snubbers shall be tested at least once per refueling outage until the entire population has been tested. This testing cycle.shall then begin anew. For cach large bore steam generator hydraulic snubber that does not meet the functional test acceptance criteria, at least 10% of the remaining population of untested snubbers for that testing cycle shall be tested. The sample plan shall be selected prior to the test period and cannot be changed during the test period. The NRC shall be notified of the sample plan selected prior to the test period.

1) At least 10% of the snubbers required by SLC 16.15-3.7.8 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 SLC 16.15-4.7.8f, an additional 10% of the snubbers shall be functionally tested until no more failures are found or until all snubbers have been functionally tested; or

2) A representative sample of the snubbers required by SLC 16.15-3.7.8 shall be functionally tested in accordance with Figure 4.7-

1. "C" is the total number of snubbers found not meeting the acceptance requirements of SLC 16.15-4.7.8f (failures). The cumulative number of snubbers tested is denoted by "N." Test results shall be plotted sequentially in the order of sample assignment (i.e., each snubber shall be plotted by its order in the random sample assignments, not by the order of testing). If at any time the point plotted falls in the " Accept" region, testing of snubbers may be terminated. When the point plotted lies in the " Continue Testing" region, additional snubbers shall be tested until the point falls in the " Accept" region, or all the snubbers required by SLC 16.15-3.7.8 have been tested. Testing equipment failure during functional testing may 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 the day of equipment failure are retested; or 16.15-42 f

(

b G -3) An initial representative sample of 55 snubbers shall be functionally tested.

For each snubber 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 multiplied '

by the factor, 1 + C/2, where "C" is the number of snubbers found which do not meet the functional test acceptance criteria. This 1 can be plotted using an " Accept" line which follows the equation  !

N = 55(1 + C/2). Each snubber should be plotted as soon as it is tested. If the point plotted falls on or below the " Accept" line, testing may be discontinued. If the point plotted falls above the

" Accept" line, testing must continue unless all snubbers have been tested, 10 9

FIGURE 4.7-1 SAMPLE PLAN 2) FOR SNUBBER FUNCTIONAL TEST 16.15-43 4/99

l The representative samples for the functional test sample plans shall l I

i

' be randomly selected from the snubbers required by SLC 16.15-3.7.8 and j 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 sizes, and capacities. 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.

l 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 that 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 achieved within the specified I range in both tension and compression, except.that inertia depen-dent, acceleration limiting mechanical snubbers may be tested to verify only that activation takes place in both directions of I travel;

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

3) Where required, the force required to initiate or maintain metion

[ \ of the snubber is within the specified range in both directions

\s.s# of travel; and

4) For snubbers specifically required not to displace under con-tinuous load, the ability of the snubber to withstand load with-out displacement.

Testing meth'ods 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 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 to the same failure mode.

For the snubbers found inoperable, an engineering evaluation shall be performed on the components to which the inoperable snubbers are attached. The purpose of this engineering evaluation shall be to determine if the components to which the inoperable snubbers are s

16.15-44 4/99

/N attached were adversely affected by the inoperability of the snubbers

( ,) in order to ensure that the component remains capable of meeting the designed service.

If any snubber selected for functional testing either fails to activate 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 evaluated in a manner to ensure their OPERABILITY. This testing requirement shall be independent of the requirements stated in SLC 16.15-4.7.8e for snubbers not meeting the functional test acceptance criteria.

h. Functional Testing of Repaired and Replaced Snubbers l

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 freedom-of-motion test must have been performed within i 12 months before being installed in the unit.

i. Snubber Seal Replacement Program The seal service life of hydraulic snubbers shall be monitored to ensure that the service life is not exceeded between surveillance I h s_ ) inspections. The expected service life for the various seals, seal materials, and applications shall be determined and established based on engineering information and the seals shall be replaced so that the expected service life will not be exceeded during a period when the snubber is required to be OPERABLE. The seal replacements shall be documented and the documentation shall be retained in accordance with QA Topical Report BASES:

I All snubbers are required OPERABLE to ensure that the structural integrity of the Reactor Coolant System and all other safety-related systems is maintained during and following a seismic or other event initiating dynamic loads. Snubbers excluded from this inspection program are those installed on nonsafety-related systems and then only if their f ailure or failure of the system on 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 example, mechanical snubbers utilizing the same design features of the 2 kip, 10 kip, and 100 kip capacity manufactured by Company "A" are of the same t ype . The same design mechanical snubbers manufactured Company "B" for the pur-poses of this specification would be of a different type, as would hydraulic snubbers from either manufacturer.

16.15-45 O

V 4/99

i The visual inspection frequency is based upon maintaining a constant 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 deter-l mine the next inspection. However, the results of such early inspections per-formed before the original required time interval has elapsed (nominal time less 25%) may not be used to lengthen the required inspection interval. Any inspec-l tion whose results require a shorter inspection interval will override the l previous schedule.

To provide assurance of snubber functional reliability one of the three sampling and acceptance criteria methods are used:

1 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 determine sample acceptance or continue testing

• using Figure 4.7-1, or I l

l 3. Functionally test a representative sample size and determine sample acceptance or rejection using the stated equation.

l Figure 4.7-1 was developed using "Wald's Sequential Probability Ratio Plan" as 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 snubber for the applicable design conditions at either the completion of their fabrication or at a subsequent date.

The service life of a snubber is established vic 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 l ensure that the snubbers periodically undergo a performance evaluation in view of their age and operating conditions. These records will provide statistical i

bases for future consideration of snubber service life. The requirements for the maintenance of records and the snubber service life review not intended to affect plant operation.

l l If testing continues to between 100-200 snubbers (or 1-2 weeks) and still the accept region has not been reached, then the actual % of population quality (C/N) should be used to prepare for extended or 100% testing.

,,) BASES:

j This SLC is provided to ensure that groundwater levels will be monitored and prevented from rising to the potential failure limit for the McGuire Units 1 and i

2 Auxiliary Buildings. This potential failure limit is based on engineering calculations that have determined that the Auxiliary Buildings are susceptible to overturning due to buoyance at elevation 737 feet Mean Sea Level (MSL).

Under the requirements of this SLC, if groundwater level exceeds elevation 731 feet MSL, (3 out of 5 SLC groundwater monitor alarms), and cannot be reduced in one (1) hour, McGuire must begin reducing Units 1 and 2 to Mode 5, Cold Shutdown.

Analysis performed by Design Engineering determined that the Reactor and Diesel Generator Buildings are designed to withstand hydrostatic loadings due to groundwater levels up to elevation 760 feet MSL; therefore, no SLC requirements are specified for these structures.

Elevation 731 feet MSL is the action level of the five groundwater monitors listed in Table 3.7-7. The East Wall exterior monitor alarm At elevation 731 feet MSL is the Alert alarm. The other four (4) monitors are Hi-Hi alarms at elevation 731 feet MSL.

The East Wall exterior monitor was originally on the exterior of the Unit 2 i Auxiliary Building and subsequently was enclosed by the construction of the l Equipment Staging Building.  !

fs As required by Operations procedures, any alarms on non-SLC groundwater monitors

) will also be investigated. Additionally, if three (3) out of the five (5) l groundwater monitors alarm at levels below the action levels, Cperations will contact Duke Engineering (Civil) for investigation and resolution of the increased groundwater level.

If one or more of the 5 SLC groundwater monitors is determined to be inoperable, the monitor (s) will be considered to be indicating above the 731'-0" MSL until repaired and returned 'to an operable status.

3) The battery capacity is adequate to supply and maintain in OPERABLE status its emergency loads when subjected to a battery service test. .-

BASES:

The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory Guides 1.9, " Selection of Diesel Generator Set Capacity for Standby Power Supplies, " March 10, 1971, 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear

, Power Plants, " Revision 1, August 1977, and 1.137, " Fuel-Oil Systems

\,

for Standby Diesel Generators," Revision 1, October 1979; Generic Letter 84-15, which modified the testing frequencies specified in Regulatory Guide 1.108; Generic Letter 93-05, which reduced the surveillance requirements for testing of Diesel Generators during power operation; also, Generic Letter 94-01, which removed the accelerated testing and special reporting requirements for Emergency Diesel Generators.

Some of the Surveillance Requirements for' demonstrating the operability of the diesel generators are modified by a footnote. The Specifications state the Surveillance Requirements are to be performed during shutdown, with the unit in mode 3 or higher. The footnote allows the particular surveillance to be performed during preplanned Preventative Maintenance (PM) activities that would result in the diesel generator being inoperable. The surveillance can be performed at that time as long as it does not increase the time the diesel generator is inoperable for the I;M activity that is being performed.

The footnote is only applicable at that time. The provision of the footnote shall not be utilized for operational convenience.

Since the McGuire emergency diesel generator manufacturer (Nordberg) is no longer in business, McGuire engineering is the designer of record.

Therefore, in the absence of manufacturer recommendations, McGuire engineering will determine the appropriate actions required for nuclear class diesel service taking into account McGuire diesel generator maintenance and operating history and industry experience where applicable.

The Surveillance Requirements applicable to lower voltage circuit breakers provide assurance of breaker reliability by testing at least one representative sample of each manufacturer's brand of circuit breaker. Testing of these circuit breakers consists of injecting a current in excess of the breaker's nominal setpoint and measuring the response time. The measured response time is compared to the 16.15-57 O

• shall be prohibited form travel over fuel assemblies in the storage pool. Truck casks shall be carried along the path outlined in Figure 3.9-1 in the fuel pit and fuel pool area.

l APPLICABILITY: With fuel assemblies in the storage pool.

REMEDIAL ACTION:

I TESTING REQUIREMENTS: .*

16.15-4.9.7, The weight of each load, other than a fuel assembly and control rod, shall be verified to be lets than 3000 pounds prior to moving it over fuel assemblies.

BASES:

The restriction on movement of loads in excess of the nominal weight of a fuel and control rod assembly and associated handling tool over other fuel assemblies in the storage pool ensures that in the event this load is dropped: (1) the activity release will be limited to that contained in a single fuel assembly, and (2) any possible distortion of fuel in the storage racks will not result in a critical array. This assumption is consistent with the activity release assumed in the accident analysis.

(See Figure 3.9-1 on next page)

Weir gates of the spent fuel pool may be moved by crane over the stored fuel provided the spent fuel has decayed for at least 17.5 days since last being part of a core at power, 16.15-62 b

a. Within 12 steps when the rods are stationary, and

b. Within 24 steps during rod motion.

BASES:

This special test exception permits the Position Indication Systems to be inoperable during rod drop time measurements. The exception is required since the data necessary to determine the rod drop time are derived from the induced voltage in the position indicator coils as the rod is dropped. This induced voltage is small compared to the normal voltage and, therefore, cannot be observed if the Position Indication Systems remain OPERABLE.

• This requirement is not applicable during the initial calibration of the Rod Position Indication System provided: (1) Keff is maintained less than or equal to 0.95, and (2) only one shutdown or control rod bank is withdrawn from the fully inserted position at one time.

i BASES:

The tanks applicable to this SLC include all those outdoor radwaste tanks that l

are not surrounded by liners, dikes, or walls capable of holding the tank contents and that do not have tank overflows and surrounding area drains connected to the Liquid Radwaste Treatment System.

Restricting the quantity of radioactive material contained in the specified tanks provides assurance that in the event of an uncontrolled release of the tanks' contents, the resulting concentrations would be less than the limits of 10 CFR Part 20, Appendix B, Table II, Column 2, at the nearest potable water supply and the nearest surface water supply in an UNRESTRICTED AREA.

TESTING REOUIREMENTS:

O 16.15-4.11.2.5 The concentrations of hydrogen and oxygen in the WASTE GAS HOLDUP SYSTEM shall be determined to be within the above limits by monitoring the waste gases in the WASTE GAS HOLDUP SYSTEM with the hydrogen and oxygen monitors required OPERABLE by Table 3.3-13 of SLC 16.15-3.3.3.9.

BASES:

This specification is provided to ensure that the concentration of potentially explosive gas mixtures contained in the WASTE GAS HOLDUP SYSTEM is maintained below the flammability limits of hydrogen and oxygen. Automatic control features are included in the system to prevent the hydrogen and oxygen concentrations from reaching these flammability limits. These automatic control features include isolation of the source of hydrogen and/or oxygen, automatic diversion to recombiners, or injection of dilutants to reduce the concentration below the flammability limits. Maintaining the concentration of hydrogen and oxygen below their flammability limits provides assurance that the releases of radioactive materials will be controlled in conformance with the requirements of General Design Criterion 60 of Appendix A to 10 CFR Part 50.

BASES:

O The specification considers postulated radioactive releases due to a Waste Gas System leak or failure, and limits the quality of radioactivity contained in l

each pressurized gas storage tank in the WASTE GAS HOLDUP SYSTEM to assure that a release would be substantially below the dose guideline values of 10 CFR Part 100 for the postulated event.

Restricting the quantity of radioactivity contained in each gas storage tank provides assurance that in the event of an uncontrolled release of the tank's contents, the resulting total body exposure to a MEMBER OF THE PUBLIC at the nearest exclusion area boundary will not exceed 0.5 rem. This is consistent with Standard Review Plan 11.3, Branch Technical Position ETSB 11-5, " Postulated Radioactive Releases Due to a Waste Gas System Leak or Failure," in NUREG-0800, July 1981.
