1 January 22, 1996

. 3/4.9 REFUELING OPERATIONS BASES 3/4.9.1 BORON CONCENTRATION The limitations on reactivity conditions during REFUELING ensure that: (1) the reactor will remain subcritical during CORE ALTERATIONS, and (2) a uniform boron concentration is maintained for reactivity control in the

, water volume having direct access to the reactor vessel. These limitations are consistent with che initial conditions assumed for the boron dilution incident in the accident analyses. A value of 0.94 or less for Ke rr is required for this accident. For a core configuration of all rods in an additional 0.05 K,rr penalty is required to account for a heavy load

, crushing the core into a more reactive configuration. )

l 3/4.9.2 INSTRUMENTATION I 1

i The OPERABILITY of the Source Range Neutron Flux Monitors ensures that monitoring capability is available to detect changes in the reactivity ,

condition of the core. Redundant monitoring capability is required to I detect changes in the reactivity condition of the core during fuel movement, i j 3/4.9.3 DECAY TIME

)

1 The minimum requirement for reactor subcriticality prior to movement of  !

irradiated assemblies in the reactor vessel ensures that sufficient time has  ;

elapsed to allow the radioactive decay of the short lived fission products.  !

i The minimum requirement for reactor hold time prior to movement of irradiated I fuel from the reactor vessel to the spent fuel poal ensures that sufficient '

decay time has elapsed for adequate spent fuel pool cooling should a failure occur to the cooling system. The reactor hold time is a function of cooling water temperature. The required decay time assumes a conservative maximum transfer rate of six assemblies per hour. These decay times are consistent I with the assumptions used in the safety analysis. l 3/4.9.4 CONTAINMENT BUILDING PENEIRATIONS The requirements on containment building penetration closure and OPERABILITY l ensure that a release of radioactive material within containment will be i restricted from leakage to the environment. The OPERABILITY and closure restrictions are sufficient to restrict radioactive material release from a fuel element rupture based upon the lack of containment pressurization potential while in the REFUELING MODE.

3/4.9.5 COMMUNICATIONS The requirement for communications capability ensures that refueling cavity manipulator crane area personnel can be promptly informed of significant l changes in the facility status or core reactivity conditions during CORE ALTERATIONS.

Hay 27, 1993 j REFUELING OPERATIONS BASES 3/4.9.6 MANIPULATOR CRANE The OPERABILITY requirements for the manipulator cranes ensure that: (1) manipulator cranes will be used for movement of control rod drive shafts and l fuel assemblies, (2) each crane has sufficient load capacity to lift a drive l shaft or fuel assembly, and (3) the core internals and reactor vessel are l protected from excessive lifting forces in the event they are inadvertently i engaged during lifting operations. l 3/4.9.7 CRANE TRAVEL - SPENT FUEL STORAGE BUILDING l

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 I 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 '

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 safety analysis.

3/4.9.8 RESIDUAL HEAT REMOVAL AND COOLANT CIRCULATION l The requirement that at least one RHR LOOP be in operation ensures that: (1) i sufficient cooling capacity is available to remove decay heat and maintain the water in the reactor vessel below 140 F as required during the REFUELING MODE, and (2) sufficient coolant circulation is maintained through the core to minimize the effect of a boron dilution incident and prevent boron stratification.

The requirement to have two RHR LOOPS OPERABLE when there is less than 23 feet of water above the reactor vessel flange ensures that a single failure of the operating RHR LOOP will not result in a complete loss of residual heat removal capability. With the reactor vessel head removed and 23 feet of water above the reactor vessel flange, a large heat sink is available for core cocling. Thus, in the event of a failure of the operating RHR LOOP, adequate time is provided to initiate emergency procedures to cool the core.

3/4.9.9 CONTAINHENT PURGE SUPPLY. PURGE EXHAUST. AND PURGE EXHAUST BYPASS ISOLATION SYSTEM The OPERABILITY of this system ensures that the containment vent and purge penetrations can be isolated upon detection of high radiation levels within the containment. The OPERABILITY of this system is required to restrict the release of radioactive material from the containment atmosphere to the environment.

The minimum water depth is consistent with the assumptions of the safety analysis.

3/4.9.12 FUEL STORAGE BUILDING AIR CLEANUP SYSTEM l The limitations on the Fuel Storage Building Air Cleanup System ensure that l

all radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere. The OPERABILITY of this system and the resulting iodine ,

removal capacity are consistent with the assumptions of the safety analysis. '

l ANSI N510 1980 will be used as a procedural guide for surveillance testing.  ;

3/4.9.13 MOVEMENT OF FUEL IN SPENT FUEL POOL The limitations of this specification ensure that, in the event of any fuel handling accident in the spent fuel pool, K,rr will remain s 0.95. ,

3/4.9.14 SPENT FUEL P0OL REACTIVITY CONDITION The limitations described by Figures 3.9 2, 3.9 3, and Figure 3.9 4 ensure that the reactivity of fuel assemblies introduced into the spent fuel racks, with no credit taken for soluble boron in .he pool, are conservatively within the assumptions of the safety analysis.

3/4.9.15 SPENT FUEL POOL COOLING The limitations on the Spent Fuel Pool Cooling System ensure there is sufficient capacity to remove decay heat produced by the stored .uel elements (1019 assemblies) and maintain the bulk pool temperature below 150'F with a maximum heat lo:d as shown in Fig. B3/4.9 1.

Requiring both SFP cooling pu s to be OPERABLE provides backup capability in the event the operating pump ils. In the event of a complete loss of forced cooiing, the time to boil, excluding the effect of evaporation, is greater than !,0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> based on current heatup calculations.

This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will result in exposures within: (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) the limits of 10 CFR 20.106(e) to the population. The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe 135 is the

controlling radioisotope and its MPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2.

3/4.11.1.2 DOSE. LIOUIDS l This specification is provided to implement the requirements of Sections II.A. III.A and IV.A of Appendix I,10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.A of Appendix I.

The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable". The dose calculation methodology and parameters in the REMODCM implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I is to be shown by calculational procedures based on models and data, such that the actual l exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the REMODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977, and Regulatory Guide 1.113.

The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, Appendix B.

Table II. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the ex30sure of an individual offsite to annual average concentrations exceeding t1e limits specified in Appendix B. Table II of 10 CFR Part 20 (10 CFR 20.106(b)). For individuals who may at times be within the site boundary, the occupancy of that individual will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the site boundary. The specified release rate limits restrict, at all times, the corresponding garrma and beta dose rates above background to an individual at or beyond the site boundary to less than or equal to 500 mrem / year to the total body or to less than or equal to 3000 mrem / year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid or other organ dose rate above background to a child to less than or equal to 1500 mrem / year from l inhalation.

3/4.11.2.2 DOSE. N0BLE GASES This specification is provided to implement the requirements of Sections II.B., III.A and IV. A of A]pendix I,10 CFR Part 50. The Limiting Condition for Operation implements t1e guides set forth in Section II.B of Appendix I.

The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I assure that the releases of radioactive material in gaseous effluents will be kept "as low as is reasonably achievable." The Surveillance Requirements implement the requirements in Section III.A of Appendix I that conform with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of an individual through the appropriate pathways is unlikely to be substantially underestimated. The dose calculations established in the ODCM for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents will be consistent with the methodology provided in Regulatory Guide 1.109,

" Calculational of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111. " Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light Water Cooled Reactors," Revision 1. July 1977.

TM ODCM equations provided for determining the air doses at the site boundary are based upon utilizing successively more realistic dose calculational methodologies. More realistic dose calculational methods are used whenever simplified calculations indicate a dose approaching a substantial portion of the regulatory limits. The methods used, in order are, previously determined air dose per released activity ratio, historical meteorological data and actual radionuclide mix released, or real time meteorology and actual radionuclides released.
