SHOREHAM DSAR [\ CHAPTER 1 INTROLUCTION AND GENERAL DESCRIPTION OF PLANT

1.1 INTRODUCTION

This Defueled Safety Analysis Report (DSAR) is an appendix to the Shoreham USAR and is submitted by Long Island Lighting Company, hereafter-known as LILCO, in support of its application to amend Facility Operating License NPF-82 as described in SNRC-1664. The description of the plant remains essentially unchanged from the description in Section 1.1 of the SNPS USAR. However, many of the sections which described systems needed to support power operation are significantly changed or excluded from the DSAR. The DSAR format is the same as that used for the USAR (i.e. NRC Regulatory Guide 1.70, Rev. 1, 1972); however, commensurate with the level of activity of a defueled plant, the content is reduced. l The purpose of the DSAR is to provide a safety analysis for the storage and handling of Shoreham low burnup first cycle spent i fuel. The DSAR confirms that-fuel storage and handling systems,

     /~' structures, components and programs ensure that there is no undue

, k,) risk to public health and safety during normal and postulated accident conditions. The DSAR assumes that the 560 fuel bundles comprising the Shoreham core are stored under water in the Shoreham spent fuel pool. The fuel bundles are held in Seismic Category I spent fuel racks within the stainless steel-lined spent fuel pool. The spent fuel pool is located in The the structures-are secondary containment of the -l Shoreham reactor building. designed to withstand seismic loads. The Shoreham spent fuel is in a low burnup condition. The Shoreham Nuclear Power Station operated during low power testing at power levels not exceeding 5% of rated power. The effective This burnup of the fuel is approximately 2 full power days. results in an estimated total core wide heat generation rate of l approximately 550 watts as of June 1989. The estimated fuelFigureheat load will reduce to approximately 250 watts by June 1991. 15.1-1 depicts the fuel heat load versus time. Based on this low l heat generation rate, systems for active cooling are not required, and only minimal capacity systems are required for pool water makeup to handle evaporation. L i O l-1 Rev. 3 July 1991

SHOREilAM DSAR The Shoreham spent fuel contains limited quantities of radioactive materials that are available for release. As is stated in DSAR Section 12.2, approximately 176,000 curies of radioactivity reside in the 560 fuel assemblies. Gaseous activity in the fuel assemblies is primarily Krypton-85 (a noble gas with a 10.7 year half-life) , and consists of approximately 1560 curies. The radioactive inventory estimation is based on a two year decay from the last burnup period (completed June 7, 1967). Other sources of radioactivity outside the core are minor, and include small amounts of contamination in the bottom of sumps, the suppression pool, inside the reactor pressure vessel, and in the radwaste systems. Chapter 15 presents radiological analyses for those accidents identified in the USAR which are applicable to the defueled plant . In addition, no other accident mechanisms were identified for the plant's defueled condition which are not bounded by Chapter 15. The events analyzed in Chapter 15 are:

1. Fuel Handling Accident (Fuel Bundle Drop)
2. Radwaste Tank Rupture The only design basis accident involving reactor fuel is a Fuel Handline Accident , in which no heat generation takes place. As ye~s such, the activity available for release in this design basis i accident is primarily Krypton-85, and consists of approximately 2.5 curies. In addition, a worst case radiological event is postulated in which the entire gaseous activity of the core is This event was postulated to released to the reactor building.

conservatively bound any possible situation involving large-scale mechanical damage of the fuel. The results of the September 1989 spent fuel radiological analysis described in DSAR Chapter 15 indicate that integrated doses are very small ir comparison with 10CFR100 limits. For the worst case scenario ir shich all the gaseous activity is assumed to be released from the entire core, a spectrum of cases were analyzed as follows: operation of the standby ventilation system, operation of the normal ventilation system, and no ventilation (modeled as puff release). The results of the analyses indicate that the integrated whole body and skin doses, with Reactor Building Normal Ventilation System operational, are less than approximately .03% of 10CFR100 limits. The results of the radiological analysis for the worst case fuel damage scenario are depicted graphically in Figure 15.1.36A-1. In particular, it l was demonstrated that the reactor building standby ventilation system operation does not provide an important filtering or ventilation safety function and is therefore no longer required after fuel is stored in the pool. Based on this analysis, it has been found that the spent fuel f[\~/) pool provides a high degree Active of passive safety protection for safety systems are not required to Shoreham spent fuel. t 1-2 Rev. 3 July 1991

SHORERAM DSAR h mitigate postulated accidents; however, support systems are required to meet the intent of 10CFR50 Appendix A, General Design Criteria (see Chapter 3 for a listing) and Regulatory Guide 1.13. Supporting systems are required to provide for radiation monitoring, fuel pool makeup, fuel pool cleanup, radwaste management, and normal building services. Therefore a reclassification of safety systems is proposed based on the importance to safety associated with each plant system with the plant defueled. The DSAR assumes that the Shoreham spent fuel f rom the initial core is to be stored for some interim period in the spent fuel pool contained within the SNPS reactor building. The assumed configuration of principal plant systems is as follows:

1. All 560 fuel bundles have been removed from the reactor and are being stored in seismic Category I spent fuel racks in the spent fuel storage pool. The total decay heat power of the entire core has been determined to be approximately 550 watts as of June 1989 (reference DSAR Chapter 15).
2. As described in DSAR Chapter 9, the spent fuel storage pool water level is maintained at its normal water level. Makeup p(f, ' will be furnished from the condensate transfer system or the
'-           demineralized and makeup water system. The fuel pool cooling system is not in service due to the low heat load in the pool. Water quality is maintained by the fuel pool cleanup system. The spent fuel pool transfer canal gates will remain installed. Fuel pool level and temperature are alarmed in the Control Room.
3. The capability for fuel handling will be maintained as described in DSAR Chapter 9.
4. The Nuclear Boiler, Reactor Protection, Emergency Core Cooling, and Primary Containment systems are not required. l This is discussed in DSAR Chapters 4, 5 and 6.
5. Two independent offsite AC power sources will be maintained In addition, as discussed to supply reliable electric power.

in Chapter 8, blackstart combustion turbines exist nearby in the Shoreham west site to supply emergency power to the plant. However, as discussed in DSAR Chapter 15, onsite Emergency Diesel Electric Power is not required to mitigate design basis accidents. AC Power is required by Technical Specifications to remain operable during fuel movement (including one non-safety emergency diesel generator) .

6. The normal ventilation system (RBNVS) provides a controlled h~')

(s and monitored release capability but secondary containment integrity is no longer required as discussed in the DSAR Chapter 15 Safety Analysis. Rev. 3 July 1991 1-3

7. The steam and power conversion systems are not required to be operable or functional.
8. Process and area radiation monitoring are maintained consistent with fuel storage and handling requirements, and are described in DSAR Chapters 11 and 12. ,
9. Radwaste Systems described in DSAR Chapter 11 are maintained to provide an appropriate level of radioactive liquid and r;olid waste management primarily due to operation of the spent fuel pool.
10. Major systems that remain functional to provide non-safety related supporting services includes a) Service Water (DSAR Chapter 9 and 10) b) Chilled Water Systems (DSAR Chapter 9) c) Compressed Air (DSAR Chapter 10) d) HVAC Systems (DSAR Chapter 9)

The DSAR addresses the following major programs:

1. Proposed revised Technical Specifications (Appendices A and B) including the basis of the specification is provided.

2. Conduct of operations and the LILCO organizational structure is described in Chapter 13. The ISEG functions are no longer considered necessary for a defueled reactor.
3. The Quality Assurance Program is maintained as described in DSAR Chapter 17. l
4. The Fire Protection Program is maintained as described in DSAR Section 9.5.1 and the FHAR.
5. An offsite Radiological Environmental Monitoring Program (ITJT) is maintained as described in DSAR Section 11.6.

The operational meteorological monitoring program uses  ! j instrumentation to determine wind-speed and -direction at 33- and l l 150-ft. ambient air temperature at-33-ft and temperature [ differential (Temp @ 150-ft minus Temp 9 33-ft). These i instruments are located on SNPS' 400 ft. meteorological tower l which is located approximately 5100-ft WSW of the reactor j building (Figure 2.1.1.1). The MET tower was positioned  ! sufficiently close to SNPS to provide representative observations i of released gaseous effluents, but far enough away to minimize } atmospheric disturbances caused by SNPS' structures. l t l Wind-speed and -direction at the 33-ft level, along with the  ! temperature differential are transmitted to the Technical Support l Center. In addition to these parameters, wind-speed and  ;

           -direction at 150-ft., and temperature at 33-ft. are transmitted        I i

to the Main Control Room and entered into the RMS computer. t A11' instrumentation was either manufactured or supplied by Climatronics Corporation, Hauppauge, New York. .The specifica-tions outlined in Regulatory Guide 1.23 were used in the selection of these instruments. Wind instrumentation includes F460 wind sets (three cup anemometers and direction vanes) at the 33 and 150 ft. levels. Temperature sensors in shielded aspirators are oriented in a northerly direction to limit the l (() influence of solar insolation. A motor and fan draw a constant 2-1

Observations from 33 ft. are used to model the dispersion of ground level release of activity, while data from 150 ft. are ' used for elevated releases. The data obtained are used to project the dispersion of plant gaseous effluents based on Gaussian model and are included in required periodic reports. To ensure the operability of the system, semi-annual calibrations l are mrformed by a qualified vendor, and channel checks are peric.med by the operators on shif t using qualitative assessment of the channel's behavior during operation. Operators do this by checking the chart recorders in the control room. This instrumentation includes:

1) Wind speed monitors at the 33-ft. and 150-ft. elevations;
2) Wind direction monitors at the 33-ft. and 150-ft, elevations;
3) Ambient ten.erature monitor at the 33-ft elevation; and
4) Differential Tir temperature monitor which uses the temperature data recorded at 33-ft, and 150-ft. elevations.

I Meteorological sensors are replaced on a semi-annual basis with replacement sensors which have been calibrated in the laboratory - of a qualified vendor. Vendor personnel perform the sensor I'\ substitutions under the direction of LILCO personnel. LILCO \~ technicians perform normal maintenance and inspection on ' instrumentation at the tower. Calibration and maintenance procedures have been developed for field testing and maintenance of each meteorological channel at the Shoreham site. Spare sensors and auxiliary equipment are available for l replacement of any malfunctioning components of the system. In i the event that a Technical Specification meteorological tower instrument is damaged, causing one or more monitoring instrumentation channels to be inoperable for more than seven (7) days, refer to the Technical Specifications for the required action. , 2.4 EYDROLOGIC ENGINEERING The description contained under this heading in the latest revision of Shoreham USAR remains unchanged with the exception of Subsections 2.4.8.1 and 2.4.11.5: 3 2.4.8.1 Canals The USAR requires that the Intake Canal bottom be monitored on a , yearly basis, and dredging carried out when the results of the annual monitoring indicate cumulative sediment deposition has h exceeded one (1) foot. This one (1) foot maximum sediment depth , requirement is based upon anticipated sediment deposition of 3.2 2-2 Rev. 3 July 1991 l i

SHOREHAM DSAR 9,/ feet during a low water Probably Maximum Hurricane (PMH) event. For the defueled condition, design for the PMH is not required since the decay heat load of the fuel is negligible. Annual monitor:r. and dredging will not be required during the time that the plant is expected to be in the defueled condition. This is based on the May 1990 Intake Canal soundings and the current rate of sediment deposition. However, the intake canal will continue to be used as a source of cooling water for normal plant needs (refer to DSAR Section 9.2.1) . 2.4.11.5 Plant Requirements The USAR states that the required minimum safety related cooling water flow is 12,800 gpm supplied by two service water pumps. This minimum safety related flow is no longer required for the defueled condition since the RBSW system is considered non-safety related because it does not provide cooling water to any plant equipment required to perform a safety function. One RBSW pump will be used to supply cooling water for normal plant needs (see DSAR Section 9.2.1). 2.5 GEOLOGY AND SEISMOLOGY The description contained under this heading in the latest revision of Shoreham USAR remains unchanged.

SHORERAM DSAR Fual Storage and Handling and Radioactivity Control (Cdterion 61) t criterion-The fuel storage and handling, radioactive waste, and other systmas which may contain radioactivity shall be designed to asmae adequate safety under normal and postulated accident - comutions. These systems shall be designed, (1) with a capellity to permit appropriate periodic inspection and testing of components important to safety, (2) with suitable shielding for radiation protection, (3) with appropriate containment, confinement, and filtering systems, (4) with a residual heat rammal capability having reliability and testability that reflects the importance to safety of decay heat and other residual heat removal, and (5) to prevent significant reduction in fuel storage coolant inventory under accident conditions. De sign - con f ormance Fuel Storage and Handling The low burnup SNPS spent fuel is to be stored in the spent fuel storage pool located in the reactor building. The fuel racks and fuel pool structure are Seismic Category I. Systems required for O safe fuel storage will be subject to appropriate inspection and testing requirements. Adepate shielding is provided by maintaining a minimum water depd1 over the active fuel. Dose rates at the refueling level widmut the ef fects of shielding were calculated to be approximately 1R/HR. The SNPS Secondary Containment is a Seismic Category I controlled leakage building surrounding the fuel pool f acility. The Reactor , Building Normal Ventilation System (RBNVS) will be used-to provide ventilation and a monitored release pathway. Because the l gas activity present in the fuel and available for release is prhurily noble gas (Kr-85) , the filtering role of the Reactor Building Standby Ventilation System (RBSVS) is not required. Cutain components of the RSSVS are needed to support operation of the RBNVS. - These components will remain functional to provide these services. As discussed in Chapter 15, credible potential releases from accidents are small in comparison to 10CFR100-1hdts, and neither the Reactor Building Standby Ventilation Systen nor secondary containment integrity is required to reduce offsite doses due to postulated accidents. Radiation monitoring is provided as described in Chapter 11 and 12 to detect radiological releases. Because of the extremely low residual heat load (approximately 550 watts) associated with the SNPS spent fuel, active fuel pool 3-9 Rev. 3 July 1991 e

SHOREHAM DSAR r Y Reliable fuel pool makeup sources 9 cooling is not required. including condensate storage, demineralized water, and fire protection water, are capable of maintaining pool water inventory to compensate for evaporation. Chapter 9 contrins a complete discussion of makeup requirements. The fuel pool is a Seismic Category I structure. Systems that connect to the pool (fuel pool cooling, fuel pool cleanup, etc.) have been designed to minimize the potential for draining of the pool inventory. High and low level alarms indicate pool water level changes in the main control room. Radioactive Waste Systems The radioactive waste systems provide all equipment necessary to collect, process, and prepare for disposal of all radioactive liquids and solid waste produced as a result Any of spent fuel85 will Krypton storage. The off-gas system is rot needed. be retained within the fuel cladding. Should pin-hole leaks devalop, the gases will be handled by the ventilation systems. They will be discharged to atmosphere via the main plant vent. The radiological consequences of this type of release are negligible. This accident is bounded by the analysis of the fuel Handling Accident (Section 15.1.36). Liquid radwastes are collected, classified, and treated as high (r^} (_j conductivity, lou conductivity, chemical or laundry wastes. processing includes filtration, ion exchange, analysis, and dilution. Wet solid wastes are packaged in steel containers or polyethylene high integrity containers. Dry solid radwastes are compressed and/or packed in steel drums or boxes. Accessible portions of the spent fuel pool area and radwaste building have sufficient shielding to maintain dose rates within the limits set forth in 10CFR20 and 10CFR100. The radwaste

building is designed to preclude accidental release of l radioactive materials to the environs above those allowed by the applicable regulations.

The fuel storage and handling and radioactive waste systems are designed to assure adequate safety under normal and postulated I accident conditions. The design of these systems meets the requirements of Criterion 61. Radwaste systems are designed to meet the limits for effluents set forth in 10CFR20 and 10CFR50. l Prevention of Criticality in Fuel Storace Handlina l ((riterion62)_ Criterion (s\ b 3-10 l b

Criticality in' spent fuel storage is geometrically safe configuration of the storage rack.

These systems satisfy the requirements of Criterion 63. Monitoring Radioactivity Releases (Criterion 64) Criterion Means shall be provided for monitoring the reactor containment atmosphere, spaces containing components for recirculation of loss of coolant accident fluids, effluent discharge paths, and the plant environs for radioactivity that may be released from normal operations, including anticipated operational occurrences, and from postulated accidents.

A set of postulated accidents has been , identified and analyzed in Chapter 15 of this report that l defines the potential for a radiological release. Based on this analysis it has been concluded that potential radiological releases are far below the exposure limits of l 10CTR100. The analysis in Chapter 15 of this report assumes j that the structural integrity of the filled fuel pool, fuel  : pool liner, reactor building structure and fuel racks  ! together form a passive safety system that requires a seismic .

The quality group classification in USAR Table 3.2.1-1 reflects the original design basis. As analyzed in Chapter AS, active cooling of the spent fuel pool is not required and pool makeup requirements are minimal. Supporting systems are required to maintain building habitability, provide radiation monitoring capability, and normal operating service functions.

Since the fuel has been removed and stored g in the fuel poni, LOCA or HELD cannot occur (see Chapter 15), and g' there is no potential for creation of harsh environment (i.e., the remaining design basis accidents discussed in Chapter 15 do not result in harsh environments) .

SHORERAM DSAR CHAPTER 4 _ REACTOR This Chapter includes reactor description, mechanical design, nuclear design, thermal and hydraulic design, reactor materials and control rod drive housing supports. In the plant's defueled condition, the fuel is not in the core and the reactor is depressurized. All sections of this Chapter are, therefore, not applicable to the DSAR. Fuel storage is addressed in DSAR Chapter 9. In particular, Section 9A addresses criticality and Section 9B addresses fuel pool make-up requirements. 4.1 REACTOR SUKHA.RY DESCRIPTION The NSS system is no longer needed for the defveled condition and hence is depressurized. 4.1.1 Reactor Vessel The reactor vessel design and description are covered in USAR Section 5.4.

SHOREHAM DSAR CHAPTER 6 ENGINEERED SAFETY FEATURES 6.1 GENERAL Because of the Defueled Plant Configuration, there is no longer a need for engineered safety features (ESP) systems at Shoreham. This is substantiated by_a review of the Design Basis Accidents and Postulated Transiento. These are covered in Chapter 15. This chapter discusses the effect of radiological accidents in the Secondary Containment. The Secondary Containment is utilized for maintaining a controlled and monitored release point for the design basis accident, the Fuel Bundle Drop accident. In ! addition, a worst case release of the entire gaseous inventory of the fuel is postulated in Chapter 15 that bounds Any possible large scale mechanical-damage event. 6.2 CONTAINMENT SYSTEMS [ t 6.2.1 Containment Functional Design

A 6.2.1.1 Design Basis i I

6.2.1.1.1 Safety Criteria . t The primary containment system is not required and will not be i maintained functional as there will be no fuel within the primary [ containment structure. The secondary containment will maintain a t_ ' j subatmospheric pressure for postulated radiological accidents to  ; j assure radiological monitoring of building releases. It is not needed to mitigate the consequences of sn accident. l 6.2.1.1.2 Design Basis Accidents The major design basis accident identified which will affect the secondary containment is the Fuel Handling Accident (Fuel Bundle l Drop). The results of this accident from a radiological  ; l t standpoint are presented in Chapter 15. There are no pressure l and temperature effects of this accident and the RBNVS would [- l continue to maintain a subatmospheric condition. The other event which would have an effect on the secondary l containment is the loss of normal AC. l O  ! 6-1 Rev. 3 July 1991 f i  !

SHOREHAM DSAR O A loss of normal AC power may result in loss of the-substmospheric conditions within the secondary containment and a loss of spent fuel pool water makeup capability. However, as explained in Chapter 15, should the loss of AC power occur as part of any event which.results in fuel damage, while the radioactive releaee to the atmosphere would not be monitored, the offsite dose c.>ns_equences to the public would be insignificant. With regard to loss of spent fuel pool water makeup capability, evaporative loss would be so slow that corrective action would be taken before loss of shiel(ing is significant. There are no radiological consequences ns ociated wft! the loss of normal AC power. O . O I I 6-1A Rev. 3 July 1991

 ,a CHAPTER 8 ELECTRIC POWER

8.1 INTRODUCTION

This chapter describes the details of the plant auxiliary power distribution system which is designed to provide adequate electrical power to all plant equipment. The defueled condition of the plant does not require the operation of any Class 1E power system. However, as stated in Section 8.3.1 item 2, a diesel generator and associated equipment shall remain operable while fuel handling is taking place. 8.1.1 Utility Grid The description contained under this heading in the latest revision of the Shoreham USAR remains unchanged in the defueled condition.

8,1.3 Offsite Power System While in the defueled condition the offsite power system provides power to all operating plant equipment. Power to the Shoreham Nuclear Power Station is provided f rom the LILCO system through 13BKV or 69KV circuits. The 138KV switchyard is arranged in a two bus configuration with circuit breakers and switches arranged Four to permit isolation and/or repair of either bus section. 138KV circuits enter into the switchyard (two per bus) each containing a circuit breaker at the connection to its respective bus. Two separate rights-of-way are provided, each containing two of the 138KV circuits. The 69KV circuit from the Wildwood substation enters the site sharing one of theThis aforementioned circuit, however, rights-of-way for a distance of one mile. is mounted on separate towers and is separated from the 138KV circuits. The detailed description of the remaining offsite system remains as described in the USAR except as follows: Three Brookhaven 80MW (each) Combustion Turbine units are located on LILCO SNPS property approximately 3600 feet from the 138KV g- switchyard. These units are connected into one of the 138KV k-]J 8-1 Rev. 3 July 1991

1. Spent fuel storage space is designed to accommodate 2,176 fuel assemblies (390 percent of the full core fuel load);

however, currently only 1,420 storage cavities have been  : installed and are available to receive spent fuel assemblies  ; (See Figure - 9.1.2-1 revised for DSAR) . The remainder of this Section, paragraphs 9.1.2.1.2 through , 9.1.2.1.10,- is identical to the USAR. j j} f 9.1.2.2 Facilities Description i

Spent fuel storage racks provide a place in the spent fuel The pool for storing spent fuel received from the reactor vessel.  : location of .the spent fuel pool within the reactor buf1 ding is i shown on Figure 3.8.1-4. The general arrangement of the storage I space, illustrated on DSAR Figure 9.1.2-1, will permit the i storage.of 2,176 fuel assemblies (the current installed capacity in the spent fuel pool 11s for 1,420 fuel assemblies) plus 144 l control rods.

t 9.1.3 Fuel Pool Cooling and Cleanup System All of the equipment in this system will be retained for Since the fuel pool cooling l operation, but in a modified manner. l subsystem is designed to remove the decay heat produced by spent fuel assemblies, as described in the USAR, and only a negligible i amount of heat is expected to be generated from the slightly irradiated spent fuel bundles stored there, the cooling mode is i not required Thus reactor building closed loop cooling water is  ! l not remd" . Appendix 9B provides an evaluation of spent fuel pool makeup requirements. ' However, the spent fuel pool cooling subsystem will be used in the makeup mode in order to provide normal makeup water to the i fuel pool from the condensate. storage tank using the condensate transfer and storage system. Alternate makeup sources for the i'

  +-      spent fuel pool are Demineralized and Makeup Water System, Fire k ,')   Protection Water System, and the Service Water System. The makeup mode is described at the end of USAR paragraph 9.1.3.2.1.                   (

The fuel pool cleanup subsystem will be used as designed. The fuel pool cannot be inadvertently drained because the pump suctions for the fuel pool cooling and cleanup system are taken i above elevation 168, or about 7 feet below the normal water level. If a break occurred in these lines, about 18 feet of 4 f water would remain above the fuel in the pool.- This is more than enough to provide adequate shielding. Pump returns to the pool i are equipped with siphon breakers to prevent inadvertant pool l drainage. l 9.1.4 Tuel Handling System  ! 9.1.4.1 Design Basis  : i See USAR.

This system is described in the USAR. Changes in status are addressed below. Raactor Building The only source of radioactive waste- to the Equipment and Floor Drainage System in the Reactor Building is the Fuel Pool and associated service equipment leakage. Sources in the USAR that are no longer applicable are the Drywell Equipment Drain System and the-Reactor Recirculation Pumps Drainage System. The Drywell Equipment Drain Tank is no longer required. One or more floor drain sumps are no longer required, as applicable. Turbine Building The Turbine Building Floor Drain and Equipment Drain Systems are= no longer required, as applicable, except for the Decontamination Sump drains and' associated equipment. There is n,o steam and the turbine is no longer-required, so that the only source of radioactive waste is the Chemical Laboratory. Radwaste Building The Radwaste Building Equipment and Floor Drainage System is {) maintained operational. The Dirty Waste Sump and Pumps (1N52-TK 114.and 1N52-P-187A/B) and Regenerant-Recovery Sump and Pumps (1N52-TK-115 and 1N52-P-181A/B) are no longer required. 9.3.4 Chemical, Volume Control, and Liquid Poison Systems The Standby Liquid Control System is no longer required in the

The design basis section applies with the following addition l The basic premise of the fire protection discussions in the USAR  ; and THAR is protection from fire for safety related areas (1)  ; including areas containing equipment or circuits that are i required for, safe shutdown, or (2) required to prevent or '

                       ' mitigate radiological releases comparable to 10CTR 100 limits.

Since safe shutdown is assured by non-operation of the plant, and  ; all of the nuclear fuel is in the fuel storage pool, the only [ remaining safety related area is the Reactor Building. 7 Structures, systems components and administrative controls in place to protect areas, equipment or circuits previously l* identified as safety related will be maintained as required for property loss prevention purposes and should be considered the  ! same as those fire protection features described in the USAR for ' protection of non-safety related areas. i Three documents which were used in the design of the plant's fire i protection features and continue to be part of the fire j protection program are: Evaluation of the SNPS Tire Protection Program as compared to 1. 10CTR50, Appendix R criteria submitted via SNRC 572 dated May [ 21, 1981,

However, the " safety related" application of the listed documents, particularly HRC's Branch Technical position APCSB 9.5-1 and Appendix A thereto, is limited to the Reactor Building. Locations of Fires The " locations of fires" section applies with the following changes: The rooms listed parenthetically as examples of safety related areas having a concentration of cables are reclassified to 0. A. Category II. The rooms listed as examples of where oil fires l could occur near safety related equipment no longer fit that description because these areas are reclassified to QA Category II. Furthermore, the fire hazard associated with this equipment l 1s significantly reduced while the equipment is not being used because the ignition sources associated with the operating equipment have been eliminated. ( Intensity of fires This section applies without change. Fire Characteristics This sec+. ion applies without change. Building Arrangement and Structural reatures The ' building arrangement and structural features" section applies with the following changes: In the response to NRC question 3, as shown in FRAR revision 3, SNPS has stated our intention to replace existing motorized fire dampers with newly designed fire dampers. All of the areas where these new dampers were to be installed are in the Control Building and are reclassified to Q.A. Category II. Therefore, The CO l this proposed modification will not be implemented.Whenaftheis systems for those rooms are in electric lockout. detected, the CO, system controls would cause the dampers to close on an electrical signal. As a backup, the fusibic link of each of the existing fire dampers is sufficient to cause closure of a damper in the event of a fire, thus assuring integrity of the fire barriers. Rev. 3 9-11 July 1991

SHOREHAM DSAR In contrast with this USAR section, an unprotected HVAC opening exists in the east wall of each of the three diesel generator rooms within 50 feet of an oil-filled (Reserve Station Service) transformer. This deviation was reported to the NRC on Licensee Event Report 87-021. The proposed corrective action was to install a deluge water curtain system below the existing missile shield wall between the transformer and the wall openings. Since the diesel generator rooms are reclassifisd to QA Category II, l this modification will not be implemented. The partial protection provided by the missile barrier is considered sufficient for non-safety related areas. Seismie Design This section applies without change. Water Recuirements The " water requirements" section applies with the f ollowing additional statement: Although some areas previously identified as safety related are reclassified to QA Category II, the water supply is not being l reduced.

SNPS will continue to meet the requirements of the applicable NTPA codes for fire protection systems that remain functional. 9.5.1.2 System Description The ' System Description" section applies with the following changes: As discussed earlier, all fire protection features remain in place. Several rooms / areas listed in this section as safety related are reclassified to Q. A. Category II. Essential circuitry installed for safe shutdown of the plant is no longer needed for that purpose. No removal of such cable or change in its physical separation is contemplated. Similarly, the service water line inside the Reactor Building, where a spare connection exists for manual hookup to the fire protection water system, is reclassified to Q.A. Category II.

The statement in the USAR relative to maintenance and laboratory gases remain unchanged. The safety evaluation discussed in section 9.5.9.3 of the USAR is only applicable for air for instruments, service-breathing, and control and for carbon dioxide and halon. Statements relative to the pressure relief valves and gas release hazards remain as discussed in the USAR. Gas nLe for-safe shutdown is no longer necessary in the defueled

SHOREHAM DSAR () Appendix 9A TUEL CRITICALITY ANALisis The Shoreham Spent Fuel Rack (STR) is of a stainless steel and water neutron flux trap design which uses no additional poison. A description of the storage racks is provided in 9.1.2. The criticality analysis of this rack design is described in detail The reactivity results in Appendix 9A of the Shoreham USAR, which are summarized in USAR Table 9A-4 remain valid for the rurthermore, conditions existing at Shoreham after defueling,

              .due to the differences in U-235 enrichment between the SrR designed and the current Shoreham fuel, a large negative reactivity credit should be taken into account. This is explained as follows:

The Shoreham SrR design is based on a maximum U-235 enrichment of 3.1 wt. t. The resulting basic cell k is calculated to be 0.9129 without uncertainty and model adjustments (Table 9A-4, Appendix 9A, Shoreham USAR). The Shoreham Cycle 1 fuel loading uses three (3) enrichments. Cf the 560 fuel assemblies in the core, 340 bundles have the highest bundle average U-235 enrichment of 2.19 wt. 4, 144 bundles of 1.76 wt. t and 76 remaining bundles uses natural uranium. i If the six inch natural uranium segments at the top and bottom of the fuel are excluded, the average enrichment of a l i 2,19 wt. t bundle becomes 2.33 wt. 1. Using this enrichment and linearly extrapolating the reactivity vs. U-235 I enrichment results given in rigure 9A-5 of Appendix 9A, Shoreham USAR, the reactivity difference between the SrR design enrichment of 3.1 wt. t and the current maxiumum loading enrichment of 2.33 wt. t is found to be about -6.0% in k ( k -0.060). This brings the basic cell k under nominal storage conditions for the current fuel down to f 0.85, which is well below the regulatory acceptance criterion of k 0.95. All the corrective and uncertainty adjustments listed in Table 9A"4 of the Shoreham USAR remain applicabic. During the period from July, 1985 to June, 1987, Shoreham went through three separate stages of low power testing (less than 5% of rated power), which resulted in a total core exposure of approximately 48 mwd /MT as determined by a series of core-follow analyses. The net effect of the core exposure is a slight k) mainly due to the  : decrease in reactivity ( -0.002 in i offsntting contributions from the formation of Sm-149 and the I slight depletion of the burnable Gd poison in the fuel bundles.  : i In light of the large reactivity margin described previously (k '

0. 6 5) , no additional credit will be claimed here.

t l SHORERAM DSAR f^ 9B IVALUATIO11 OT SPENT FUEL POOL MAKEUP REQUIREMEllTS An analysis was performed to determine the rate of water loss ' fram the spent fuel pool through evaporation under the worst case r,cenario described below. The following conservative assumptions  ; are used in the analysis to maximize the calculated pool , evaporation rates  !

1) The spent fuel pool temperature is 110*T. (
2) The ambient temperature above the spent fuel pool is  :
        -     conservatively assumed to have zero relative humidity.                                                                                    l
3) The reactor building air flow exists due to normal ventilation system operation to maximize evaporation.

The result of the calculation shows that the maximum evaporation rate from the pool is approximately 0.6 gpm which translates to a pool level depletion rate of one foot per eleven days. Based on i this very low maximum depletion rate, external cooling of the r spent fuel pool is not required. Technical Specifications l' require that the water level above the spent fuel be a least twenty-one feet. In addition, it should be noted that pool water level is alarmed in the control room and alarm response l procedures exist to provide appropriate operator action. i P r 1 l i l + l  ! t t i 9-17 Rev.

RADIOACTIVE WASTE MANAGEMENT J1.1 RADIATION SOURCE TERMS The description contained under this heading in the latest revision of Shoreham USAR remains unchanged as it is used to develop the basic design criteria of the plant. However, the actual source terms in the plant's present defueled condition are as follows:

a. Liquid Radioactivity Sources As of August 1989, since all SNPS' fuel had been placed in the spent fuel pool, there were no liquid sources with nuclide concentrations greater than the Lower Limit of Detection (LLD),

outside of radwaste streams. It must be recognized that in the future some concentrations greater than LLD will be seen (e.g., as sludge at the bottom of sumps is processed to Radwaste). l However, these should be minor and temporary occurrences. Sources related to the decontamination and decommissioning should also be minor, as the degree of overall plant contamination is low. These liquid sources would be dealt with in accordance with the Liquid Radwaste, ALARA, and Health Physics programs as discussed in DSAR Sections 11.2, 12.1, and 12.5, respectively. i( ) Isotopic concentrations above the LLD levels in the Radwaste System as of 6/30/89 are indicated in Table 11.1-1, from References 2, 3 and 4.

b. Gesecus Sources There are no detectable gaseous sources at SNPS, either present or anticipated. This statement is supported by the fact that the Semi-Annual Radiological Effluent Release Report for the first and second quarter 1989 (Reference 1) indicates there were no detectable releases during the six-month period, either from the offgas system or the various building exhaust systems.
c. Activated Materials Sources l

It is expected that materials which were located in the reactor vessel during low power testing (eg, control rods, TIPS, IRMs, and the like) have been activated to some extent. With the l ~ exception of some portions of the liquid radwaste system (10 mrem /hr maximum) , dose rates outside of plant systems are very low, less than 0.5 mrem /br. Thece low dose rates are indicative of a low deposition of sources within plant systems. O 11-1 Rev. 1 Aug. 1990

SHOREHAM DSAR h There may be a minor amount of activation source material deposited within plant systems. However, the level of this activity, and indeed of the activation products within the reactor vessel itself, are not considered significant compared to the spent fuel sources described in Section 12.2.

I 11.2.8 Dilution Factors Under the plant's present condition, service dater or circulating water will be used, if necessary, for dilution so that the discharged effluent concentration in the Long Island Sound will not exceed that prescribed in 10CFR20, Appendix B, Table II, Column 2. Treated radioactive effluents are collected in the discharge sampic tanks. The filled tank is sampled, and then discharged at a maximum rate of 150 gpm for a period of approximately 2.5 , hours. If necessary, the treated effluent in diluted with about 8000 gpm of service water prior to discharge into the sound. Thus, if necessary a dilution factor of approximately 50 may be obtained during actual discharge. No credit is taken for the external dilution factor, i.e. the ! mixing ratio in the Sound, for service water.

Monitoring Program [REMP) are to identify and measure plant ' generated radioactivity in the environment andSNPS' to calculate REMP is the i potential dose to the surrounding population. designed to comply with the Plant's.Offsite Dose Calculation , Manual (ODCM) and NRC Regulatory Guide 4.15. REMP data is acquired by sampling various media in the environment and then

  • analyzing these samples for radioisotopes; Tables 11.6.3-1 and 11.6.3-2 detail the REMP sampling / analyzing program. Since REMP results vary for each sample and location, several sampling  !'

[) (_/ locations were selected for each medium using available 11-11 7 f

SHOREHAM DSAR meteorological, land, and water use data. The range of analyses performed on a sample depend on the type of sample taken. Sampling locations are designated as either indicator or control. Indicator locations provide representative measurements of radiation and radioactive materials for those exposure pathways and radionuclides (from SNPS) that lead to the highest potential radiation exposures. Control locations are placed sufficiently far from SNPS so that they will be beyond the measurable influence of SNPS or any other nuclear facility. This monitoring program implements Section IV.B.2 of Appendix I to 10CFR Part 50, by verifying that measured concentrations of radioactive materials and direct radiation are representative of the actual contamination levels and doses to the public. SNPS' REMP has been subdivided over three distinct time inte rvals : Preoperational REMP (prior to SNPS' initially achieving criticality), Operational REMP (from initial criticality until removal of the fuel from the core), and Post-Defuel REMP (after the core was transferred to the spent fuel pool). Preoperational REMP was performed to identify and determine background levels of environmental activity around SNPS, Preoperational REMP also served to verify that indeed the media being sampled and analyzed is sensitive to radiological ' fluctuations in SNPS' environs (indicator locations) and to provide effective monitoring of potential critical pathways. Preoperational and Operational REMP samples within the aquatic ' environment included surface water, algae, fish, invertebrates (clams, lobsters, etc.) and sediment. The atmospheric environment was sampled for airborne particulates, iodine, and noble gases. Milk, potable water, precipitation, game and food ! products were obtained from the terrestrial environment. Direct radiation was measured using thermoluminescent dosimeters (TLDs). The range of analyses for each sample could includes gamma l spectrometry, Sr-89 and Sr-90; I-131; H-3, gross beta, direct radiation and noble gases. Under Post-Defuel REMP, several of the above sample types, sampling locations and/or analyses are l discontinued. The current Post-Defuel REMP program is outlined in Tables 11.6.3-1 & 11.6.3-2. Preoperational REMP began in February 1977 and continued through 1984, although the of ficial Preoperational REMP period; i.e. the l time frame against which the data base from Operational REMP was compared, occurred during 1983 and 1984. The Operational REMP began on February 15, 1985 when initial criticality was achieved. Except for reactor operator training programs which required the reactor to operate at 'O 0% power' (during January 1989), SNPS has not generated radioisotopes since the last 5.0% power test, (% completed on June 6, 1987. Comparisons between the 11-12 Rev. 3 July 1991 j 1 - . l

s SHOREHAM DSAR above two phasec of REMP were documented in each annual REMP report. As of August 9,1989, SNPS' core was transferred to the spent fuel pool-as part of the agreement between LILCO, state and local governments not to operate Shoreham. This transfer prevents criticality-from being reestablished. In addition, since SNPS' last 5.0% power test was completed during June 1987, per Ref. 9, with the exception of I-129 and Kr-85, all iodines and gaseous l effluents have decayed away. Consequently, the surveillance requirements for SNFS' Post-Defuel REMP were reduced to below the operational level.

Justification for Reducing REMP to Post-Defuel Surveillance Levels
Pursuant to Reg Guide 4.1, once the initial core of the licensee has reached the point (in time) of maximum burnup, and the
licensee has demonstrated (using results from environmental media or calculations) that the doses and concentrations associated with a particular pathway are sufficiently small (comparable to preoperational levels), then the number of media sampled in the pathway and the frequency of sampling Since may be reduced to operational Tech Spec requirements. (as of August 9, 1989) the core has been in the spent fuel pool, the initial core has

() " exceeded" the point of maximum burnup. It should be noted that the concept of " normal" Tech Spec requirements as referred to in Reg. Guide 4.1, refers to a fully operational station with normal surveillance requirements. Reg. Guide 4.1 does not account for the unique condition at SNPS. Consequently, the justification for reducing REMP will be l l performed in two steps. Step one reduces Operational REMP to the i level mandated when SNPS was to become operational. Step two reduces the surveillance program further, to the revised requirements corresponding to the defueled condition. Dose calculations to SNPS' environs (1983 - 1988) were performed by analyzing positive concentrations of radioactivity detected in collected samples. Table 11.6.1-4 compares the radiological impact from each major pathway to the public during SNPS' preoperational and operational REMPs. Specifically, the radiological impact during SNPS' 5.0% power testing program (1985

       - 1987) was compared to precperational REMP.

1 In all cases, the-calculated doses during both the operational and preoperational phases of REMP were comparable. Therefore, no environmental radioactivity was identified (during any of the 5.0% power tests) as having originated at SNPS. These results satisfy the criteria established in-Reg.

The objectives of the Preoperational REMP were:

1. To identify and determine bassline radiological characteristics in the environment around SNPS (these background levels ~were then compared with data collected during actual plant operation);
2. To assure that the media being sampled and analyzed are sensitive to fluctuations in the radiological characteristics of the environs at SNPS, and to assure that REMP will be responsive to radioactivo discharges from SNPS (i.e., to identify indicator locations and critical pathways);
3. To provide effective monitoring of critical pathways of radiological effluents to unrestricted areast and
4. To train personnel and evaluate procedures, equipment and techniques which are utilized in the Operational and Post-Defuel phase of REMP, including emergency response capabilities.
  .n)

(, The years 1983 and 1984 served as theAll official preoperational data collected during period, as stipulated in Reference 8. this period were used in developing a baseline for ultimate comparison with operational data. From the levels and fluctuations of radioactivity analyzed in environmental samples it was concluded that sensitive indicators of radioactivity for the environment around SNPS had been selected. Sensitive indicators revected minute quantities of radioactive fallout from the October 1980 atmospheric nuclear weapons test by the People's Republic of China during 1980 and 1981, in addition to radioactivity remaining from two decades of atmospheric testing. Airborne particulate samples registered an increase in gross beta levels, along with identifying the gamma emitting iso'eopes 2r-95, 3b-95, Ru-103 and Ce-141. Also in 1983 and 1984, REMP sampling identified low levels ;f iodine-131 in Port Jefferson Harbor area aquatic samples. This was attributed to local hospitals treating patients for thyroid carcinoma. Along with these anomalies in the environment, expected normal background radioactivity was measured in REMP samples. Aquatic samples consisting of surface water, fish, invertebrates, aquatic plants and sediment were chosen and reflected the The normal atmospheric background radiation found in this environment. environment was sampled for airborne particulate matter, fodine, and noble gases. All airborne radiciodine analyses were below ( detectable levels. In addition, milk, potable water, game, The food

   \            products, beech sediments and rain water were sampled.

SHOREHAM DSAR results obtained from the analyses of these samples were typical

           ) of the radioactivity values usually associated with samples of these types. All radioiodine analyses of milk were below                                               '

detectable levels. Direct radiation levels were No relatively low, unusual and approximately the same at all locations. l radiological characteristics were observed in the environs of i SNPS during 1983 and 1984. A summary of the annual program results for 1983 and 1984 is given in USAR Tables 11.6.1-1 and 2. 11.6.1.2 operational REMP The objectives of Operational REMP weres i

1) Identify and measure plant-related radioactivity in the .

4) determine the effects of plant effluents on the environment. F
5) Comply with regulatory requirements and provide records to  ;

document compliance. j j t

6) Comply with the REMP requirements as outlined previously. l i

Operational REMP used the Preoperational data base to identify l l plant-contributed rcdiation, and to evaluate the possible effects l of radioactive effluents on the environment. The Preoperational  ; and Operational phases of REMP were designed to comply with l Regulatory Guide 4.15 (5) and the associated Branch Technical Position (4). ] Analyses of the environmental samples show results (8) consistent with those found during the preoperational years (1983 - 1984). Sensitive indicators revealed minute quantities of radioactive fallout remaining from the October, 1980 atmospheric nuclear weapons test by the Peoples _ Republic of China. Radioactivity traces from the previous two decades of international above ground atomic bomb testing were also recorded. Radioactivity increases from the accident at the Soviet Union's Chernobyl Nuclear Power Plant (during April, 1986) were also measured. Along with these environmental anomalies, expected normal background radioactivity was measured in REMP samples between 1985 and 1988. USAR Table 11.6.1-3 summarizes results from REMP during 1985, and DSAR Table 11.6.1-4 presents a comparison of preoperatonal and operational REMP data f rom 1983 through 1988. 11-17 l

4 SBORERAM DSAR (fr) (, 11.6.1.3 Post-Operational REMP The objectives of Post-Defuel and Operational REMP are identical. , Differences in the execution of Post-Defuel REMP account for both the permanent defueling of SNPS, and experience gained during the preoperational and operational REMP phases. 11.6.2 Potential Pathways

11.6.2.1 Liquid Effluent Pathways The exposure pathways for liquid effluents are
1. External exposure from radionuclides in water; and 2.. Ingestion of fish and shellfish containing radionuclides.

The concentrations of' radionuclides expected to be released to the service water are listed in Section 11.2. Dilution of these concentrations in Long Island Sound is discussed in Section 11.2.8. USAR Section 11.6.2.1 Tontains detailed discussions about the projected doses from various liquid pathways. With the updated source terms as described in the DSAR (Sections 11.1 and 12.2), future doses from liquid pathways are expected to be a small fraction of the doses presented in the USAR. See DSAR Section (b]' A 11.2.9 for dose calculations. 11.6.2.2 Gaseous Effluent Pathways The exposure pathways for gaseous effluents are:

1) Submersion in a cloud of noble gas;
2) Drinking milk from a milking animal pastured in an areas of long-lived particulates; '
3) Eating leafy vegetables on which particulates have deposited.

The calculated air dose (using REMP when SNPS was to operate as designed) at the north-northeast site boundary is 1.1 mrad /yr from gamma radiation and 1.2 mrad /yr from beca radiation. Doses from gaseous effluent pathways are summarized in USAR Table 11.6.2-3. Computational methods are discussed in Section 11.6.2.3. A dairy survey is performed annually to-determine the location of any milking animal within a 5-mile radius of SNPS. When a milking cow or goat is found, annual doses are calculated using either current meteorological or activity release data, in accordance with the methods specified in the Shoreham offsite Dose Calculation Manual.

These locations are described in Table 11.6.3-2 and are shown in Figures 11.6.3-1 and ~2. By virtue of the liquid and gaseous effluents from the plant, REMP is divided up into four distinct categories: atmospheric, terrestrial, aquatic and direct radiation. Sampling media,  ; locations, and frequencies are discussed in the following i sections. 11.6.3.1 Sampling Media 11.6.3.1.1 Aquatic Fnvironment

/~ \  The aquatic environment is examined by analyzing samples of:   1)     -

k- Surface water; 2) Fish; and Invertebrates. Surface water samples are taken in May and October using a Niskin Bottle. The samples are placed in new polyethylene bottles following three rinses with the sample medium prior to collection. When available samples of Winter Flounder, Pseudopleuronectes americanus, Windowpane, Scophthalmus aguosus, Sea Robin, Prionotus spp, Little Skate, Raja erinacea, Blackfish, Tautog onitis and Summer Flounder, Paralichthys dentatus are taken by trawl, sealed in plastic bags, frozen, and shipped to the analytical laboratory fcr analysis. When available, invertebrate samples of American Lobster, Homarus americanus, Squid, Loligo pealeii and Channeled Whelk, Busycon canaliculata are collected by trawl. Channeled whelk are also collected using pots. These invertebrate samples are then sealed in plastic bags, irozen and shipped to the laboratory for analysis. Blue Mussels Mytilus edulis are collected by hand along jetties and soft-shell clams, Mya arenaria from Wading River are shelled and sealed in plastic bags, frozen and shipped to the analytical laboratory. in Q 11-19

The atmospheric environment is examined by analyzing airborne particulates collected on Gelman Type A/E filters using low volume air samplers (approximately I c f m) . The samplers used l are equipped with vacuum recorders for sample volume correction and to indicate sample validity and maintenance problems when they occur. Should the sampler lose vacuum due to a leak the vacuum level reading will drop to zero. Since this may occur without a corresponding loss of electric supply the exact time of the maintenance problem will be evident on the recorder chart. Sample volumes are measured using dry gas meters and corrected for differences between the actual pressure that the volume meter sees and the average atmospheric pressure. Sample volumes are corrected to standard pressure using average weekly barometric pressure (measured at Environmental Engineering Department, > Melville) and air sampler' vacuum readings. Time totalizers indicate the duration of time the sample is taken. 11.6.3.1.3 Terrestrial Environment The terrestrial environment is examined by analyzing samples of milk and food products. When available, milk samples are collected quarterly, except during the pasture season (May Milk r through October) when the sampling is increased to monthly. l samples are prepared for shipment in accordance with the

    '     instruction of the laboratory performing the analysis. Food products consisting of vegetablec and fruit are collected from area farm stands and shipped fresh to the laboratory.                    >

11.6.3.1.4 Direct Radiation . Direct radiation levels in the environs are measured with energy compensated calcium sulfate (CaSO4:Dy) TLDs, each containing four ' separate readout areas. The TLDs are annealed by LILCO prior to placement in the field. One TLD is placed at each of the 18 locations, and exchanged on a quarterly bases; these locations correspond to the 16 meteorological sectors in the general areas of the site boundary, plus two control locations (actual locations are listed in Table 11.6.3-1). The units are then packaged and shipped to the laboratory for analysis. ! 11.6.3.2 Sampling Locations and Frecuency l Typical REMP sampling locations and frequency are given in Table 11.6.3-1.

The (Reference USAR Section 12.1.2, Design Considerations. justification for lack of charcoal is the tact that as per DSAR Sections 11.1 and 12.2, Shoreham does not possess a meaningful quantity of radioiodines.

This is despite the fact that the actual source strengths and unshielded dose rates do not necessitate the degree of protection afforded. , The physical design is based upon the presumption of plant operations, with the associated source terms and unshielded dose rates as described in the USAR. Although they will not generally , be needed, operational considerations describad in the USAR (e.g, *

The activities correspond to two and four years decay (June 1989 and 1991, respectively) after the last burnup period, and reflect total core inventories for those  ; isotopes with greater than 10 curies. That the source strengths given in Table 12.2.-l are reasonable is evidenced by neasurements taken during defueling activities in  ; 1989.

Results are given in Table 12.2.-2. That the calculated and measured bundle maximum dose rates agree within about 10% on s(e~s)average gives assurance that the calculated source terms in Table i l 12.2-1 are reasonably accurate. As can be seen from the **11e 12.2-1 only long-lived isotopes remain from d.: original tinides and fission / activation products created, along h their equilibrium daughters. By far the most radiologically ignificant, from a gamma dose rate standpoint, are the Cs-137/Ba-137m pair; about 80% of the whole  ; body dose rate from a spent fuel bundle is dae to the Ba-137m photon (Reference 3). For dose assessment of accidental gescous releases (e.g., a postulated fuel handling accident), only Kr-85 is meaningful (Reference 4). 12.2.2 Airborne Radioactive Material Sources  ?

All normal paths for release of radioactive materials are monitored to ensure compliance with the requirements of 10CFR20, 10CFR50, and Regulatory Guide 1.21. Table 12.3.4A lists the monitors in service, and Table 12.3.4B provides data for each monitor.

All monitors in the process and effluent radiation monitoring system detect gross activity levels and readout and alarm in the main control room. Alarms in the main control room are by annunciators and cathode ray tube (CRT) display. There are three normal effluent relsase points from the station that require radiation monitors: the station ventilation exhaust, the liquid radwaste effluent, and the reactor building salt water drain tank. Area Radiation and Airborne Radioactivity Monitoring Instrumentation This section contains a description of the area All channels and have airborne local readout by radiation monitoring systems. means of a log-ratemeter and local audible and visual alarms.

All airborne monitors are offline monitors and ars designed in accordance with ANSI N 13.1-1969, ' Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities.' Sample lines are kept as short as possible to minimize plate out while allowing the monitor to be located in an acceesible area. Airborne radiation monitoring is provided where potentially radioactive sources exists. Each of these monitors is provided with an isokinstic nozzle which is sized to ottain a representative air sample at the normal flow in the ventilation duct from which the sample is teken. Table 12.3.4B lists the airborne monitors, and Table 12.3.4C lists the area monitors.

SHORERAM DSAL 12.4.2 Airborne Activity An area within the Shoreham f acility is described as an *airbort.e radioactivity area' if the sum of the concentrations of all airborne radionuclides divided by their respective Maximum Permissible Concentrations (MPCs) (from 10CTR20, Appendix D, Table 1, Column 1) exceeds 0.25. At Shoreham, there are noWith

the fuel in the spent fuel pool, and insignificant quantitiesitof radioactive material elsewhere (see Sections 11.1 and 12.2), is not expected that airborne radioactivity areas will exist in the future, unless systems which are currently In anticipated to this instance, remain closed are opened to the atmosphere. the radiation work permit procedure (see Section 12.5) will be applied to assure there is no release of contamination into the air. With exposures reasonably expected to be much less than 2 MPCa-brs per day and/or 10 MPCa-brs per week, paragraph 103(a) (3) of 10CTR20 indicates that exposure, and the resulting internal doses, need not be included in the dose assessment to individuals. With no " airborne radioactivity areas" postulated, doses are thus taken to be essentially zero for the defueled condition. ( It should be noted that the above conclusion will be confirmed in actual practice by the whole body counting program (see Section 12.5). Procedures are in place for taking appropriate actier.s, including investigation, when any positive whole body count occurs in excess of it of the maximum permissible organ burden (MPOB), or it of the maximum permissible body burden (MPBD). 12.4.3 Occupational Dose Assessment occupational dose at Shoreham is expected to be essentially zero for the defueled condition. This conclusion has three bases:

1) At present, the dose rates in occupiable areas are virtually all less than 0.5 mrem /hr, as described in Section 12.3.

There are no sources of radiation present which would cause the present dose rates to increase to any significant extent.

2) In the defueled condition, occupancy in measurable dose rate areas is expected to be less than or equal to that in the recent past at Shoreham. However, physical decontamination activities (beginning in 1991) will result in occupancy levels substantially exceeding the 1cvels between 1988 and 1990.

S. Landauer to Panasonic TLDs, doses have been insignificant, and due almost entirely to small statistical fluctuations rather than actual doses. Based on the above statements, it is anticipated that occupational dose at Shoreham will be essentially zero until As such, the 1991 physical decontamination activities commence. corporate ALARA goal was established at 2.5 man-rem. Doses will be measured as indicated in the Health Physics Program, Section 12.5. t 12.4.4 offsite Dose Assessment

This conclusion will be confirmed by the RERP, as described in Section 11.6. 12.5 HEALTH PHYSICS PROGRAM The Shoreham Health Physics Program, the intent of which is to provide for the protection of all permanent and temporary personnel and all visitors from radiation and radioactive i materials in a manner consistent with Federal and State regulations during all phases of operation, is described in Section 12.5 of the USAR. The program is applicable in its entirety to the defueled condition at Shoreham, with the , following exceptions j A) Handling of new fuel is no longer applicable to Shoreham. l (Reference USAR Section 12.5.1.2, Personnel Experience and Qualifications. The basis of this change nois

SHOREHAM DSAR B) The laundry facility does not contain an automated respirator washer, unloading table for same, or a respirator dryer. Cleaning of respirators is done by hand methods when necessary. Respirator fitting may at some time ka the future be moved from the Annex Duilding to another onsite location. Protective clothing is to be cleaned either onsite or offsite, as conditions warrant. (Reference USAR Section 12.5.2.1, Location of Equipment, Instrumentation and Facilities. The basis of this change is the fact that with no airborne areas currently identified, and none expected in the defueled condition, requirements for respirator use are infrequent. Also, the need to clean protective clothing is significantly reduced.) C) Deleted D) The numbers of detectors and monitoring instruments will not necessarily be maintained as indicated in USAR Section 12.5.2.2. Rather, the number maintained will be as required by the defueled plant's activities and number of personnel. (Reference USAR Section 12.5.2.2, Types of Detectors and Monitoring Instruments. Justification of this change is due to the near total decay of radiciodines at the site.

                                 )

E) Radiation Work Permits are required for work under any of the following conditions:

1. Work in a posted radiation area.
2. Entry into a posted high radiation area.
3. Work in a posted contaminated area (see Item F below).
4. Entry into airborne radioactivity areas.
5. Breach of a radioactively contaminated system boundary.

l (Reference USAR Section 12.5.3.2, Radiation Work Permits. The basis of this change is a change to station procedures. l F) Under the discussion of access control, add the definition of l a contaminated area: I l 12-9 Rev. 3 July 1991

S110REllAM DSAR () Contaminated Area Any area having removable beta / gamma-emitting' radioactive material in excess of 1000 dpm/100 sq cm, or alpha-emitting radioactive material in excess of 20 dpm/100 sq cm. (Reference USAR Section 12.5.3.3.1, Access Control. The basis for this change is a modification to the station health physics procedures, as recommended by the Institute of Nuclear Power operations, in their document INPO 85-001, eiv.1.) M Under the discussion of access control, the " secondary access facility" no loncer exists. (Reference USAR Section 12.5.3.3.1, Access Control. The basis for this change is that as of September 1, 1989, the secondary access facility was taken out of service.) H) The Corporate ALARA Review Committee (CARC) now I administrative 1y reports to the Vice President, Office of Corporate Services and Vice President, Office of Nuclear. (Reference USAR Section 12.5.3.3.4, Post-operations Review. '() The basis for this change is an organizational change. See

                                                                         ~

N> Chapter 13 of the DSAR for further details.) I) As stated in DSAR Section 12.1D, there is no longer a need to provide dosimetry to personnel entering the RCA, unless they are required by an RWP. (Reference USAR Section 12.5.3.5, Health Physics Training Program. For justification, see DSAR Section 12.1.3.1.1.) It should be noted that some of the procedural requirements or commitments indicated under the USAR Health Physics Program will not apply in the defueled condition. For example, no areas requiring reevaluation for extra shielding are anticipated, due to the low current source terms (Reference USAR Section 12.5.3.3). However, potential pources of radioactivity (during physical decontamination activities) varrant that the procedures and commitments remain in place. 'O 12-10 Rev. 3 July 1991

ACCIDENT ANALYSIS i 15.1 GENERAL , i Analytical Objective > t Chapter.15 of SNPS USAR provides the results of analyses of ' the ' l spectrum of transient and accident events which are postulated to j occur with the plant operating initially at up to maximum power.  ; The purpose of this analysis is to identify USAR transients and accidents that apply to the storage and handling of the low  ; burnup fuel. The analysis is based on the defueled condition of the plant, i.e. , the fuel is removed f rom the core and is stored in the r spent fuel pool. The total decay heat is approximately 550  ; watts, which is small enough that it could be removed by passive cooling and would not require the fuel pool cooling system. i i Normal and emergency makeups are discussed in Chapter 9. As the reactor will not be operated and the fuel is not in the

   <          reactor, most of the USAR Chapter 15 events cannot occur.               ;

i (  ! Approach to Safety Analysis  ! The safety parameter evaluated for each transient of USAR Chapter  ; 15 is the Minimum Critical Power Ratio (MCPR) which.is a measure of fuel cladding integrity. Maximum Average Planar Linear Heat i Generation Rate (MAPLHGR) is the safety parameter for the reactor ' LOCA-related accidents, and indicates whether the peak' cladding  ! temperature and the zirconium-water reaction is below the specified limits. As the decay power level is extremely low during spent fuel storage, and will not increase, MCPR and l MAPLHGR limits cannot be exceeded and are not applicable.  ? Those transients and accidents of.USAR Chapter 15 which pose the potential for a radiological release outside the primary containment are of primary concern. Heat Generation Analysis i One result from the ORIGEN2 calculation is a graph of decay heat ' or thermal power (in watts) , as a function of time. Results of this analycis are presented in Figure 15.1-1. The calculated j decay heat load as of June 1989 is approximately 0.55 kw. i 15-1

SHOREHAM DSAR (( )'It must be recognized that there are some limitations For in theORIGE processes of the code and its supporting data sets. instance, ORIGEN conveniently with the spatial variations in fuel enrichment and burnup. In addition, there are uncertainties associated with averaging of nuclear cross-section data within the thermal,Nevertheless, it resonance, and fission neutron energy ranges.

        'is not expected that large uncertainties should occur in heat load estimates. See the comparison         of calediated to measures This  gives evidence that the dose rates in DSAR Section 12.2.

decay heat load calculations are reasonable, as the same analysis (ORIGEN2) was used to generate both sets of data. Analytical Categories Each USAR Chapter 15 event is assigned to one of six analytical categories. The analytical categories and the events in each analytical category are discussed below.

1. Decrease in Core C'colant_._ Temperature This analytical category of USAR Chapter 15 events includes the following events:

y'~h 15.1.5 Pressure Regulator Failure - Open D 15.1.7 Feedwater Controller Failure - Maximum Demand l 15.1.8 Loss of Feedwater Heating 15.1.9 Shutdown Cooling (RHR) Malfunction - Decreasing i Temperature. In the spent fuel storage condition, the pressure regulator, feedwater controller, feedwater heating system and RHR system are not operating and all four transients are, therefore, not applicable.

2. Increase in Reactor Pressure Since the generator, turbine, main steam isolation valve, pressure regulator, feedwater system, condenser and RER I

systems are not operating in support of nuclear fission, the following transients are not applicable: 15.1.1 Generator Lead Rejection l Turbine Trip 15.1.2 i 15.1.3 Turbine Trip with Failure of Generator Breakers to s 15-2

SHOREHAM DSAR 15.1.4 Main Steam Isolation Valve closure ((v') Pressure Regulator Failure - Closed 15.1.6 15.1.18 Loss of Feedwater Flow , 15.1.21 Loss of Condenser vacuum 15.1.26 Core Coolant Temperature Increase The transient of this category applicable to spent fuel storage is the following: 15.1.19 Loss of AC Power A loss of AC power condition can be postulated that will affect normal support systems. However, because of the very low heat generation rate (see Figure 15.1-1) and large thermal capacity of the pool active fuel pool cooling is not required. Loss of the spent fuel pool water makeup capability will result only in a very slow evaporative loss of the pool water. This evaporation rate is so slow that ample time exists to restore normal pool makeup sources so that pool level can be quickly restored. Thus, the passive . protection provided by the spent fuel pool and low fuel decay heat eliminate the need for active makeup , Ip(_)s requirements. (The rate of evaporation is discussed in Chapter 9.) The loss of AC power will not in itself result in any release of radioactivity, as fuel movement is disallowed by Tech Specs when AC power is lost (and is virtually impossible in any event), and the decay heat of the core is so low. Should the loss of AC power occur as part of any other event which causes damage to the-fuel in the pool, while the release in this case would not be monitored, the , offsite dose consequences would be insignificant. Doses , and dose rates are bounded by the " puff release" results . given in Sections 15.1.36 and 15.1.36A.

3. Decrease in Reactor Coolant Flow Rate The recirculation pumps and recirculation flow controller '

are not operating in the defueled condition and therefore all the transients of this category are not applicable: , 15.1.20 Recirculation Pump Trip 15.1.22 Recirculation Pump Seizure 15.1.23 Recirculation Flow Control Failure With Decreasing h t Flow l V 15-3 Rev. 3 July 1991

The resulting offsite dose will be negligible and are bounded by the Radwaste Tank Rupture accident. 15.1.29,1 Seismic Event Because the spent fuel pool structure and fuel racks and handling equipment meet Seismic Category I requirements, a seismic event is not postulated to create a radiological release. 15.1.31 Main Condenser Gas Treatment System Fpilure As the main condenser is not operating, there can be no offsite dose resulting from this event. 15.1.32 Liquid Radwaste Tank Rupture Should accident occur radioactivity could be released to the environment but the effect would be negligible.

In this case, radioactive material released as a result of fuel damage is available for transport directly to the secondary containment. Table 15.1.36-1 presents the parameters used in this analysis, h) 15.1.36.3 Accident Description The most severe fuel handling accident from a radiological viewpoint is the dropping of a fuel assembly onto other fuel assemblies. The sequence of events is as follows: Approximate Event Elapsed Time Fuel assembly is being handled 0+ 1. by refueling equipment. The assembly drops. Some of the fuel rods in both 1 min. . 2. the dropped assembly and another assembly are damaged, resulting in the release of gaseous fission products to the fuel pool and eventually to the secondary containment atmosphere.

1. The operator will initiate the evacuation' of the secondary containment and securing of Secondary Containment doors, if necessary.
2. The fuel handling foreman will instruct personnel to go immediately to the radiation protection personnel decontamination area, if necessary..
3. The fuel handling foreman will make the operator aware of the accident.
4. The operator will initiate action to determine the extent of potential radiation doses by measuring the radiation levels in the vicinity of or close to the secondary containment.
5. An HP technician will post the appropriate radiological control signs at the entrance to the sece'idary containment.
6. Before entry to the secondary containment is made, a careful study of conditions, radiation levels, etc.,

will be performed. ( 15.1.36.5 HVAC Scenarios Considered As set forth in Section 15.1.36.6, the quantity of gaseous fission products in the fuel's gap which is released will Calculations not be large (2.52 Ci of Kr-85 only). indicate that the reactor building refueling floor exhaust radiation monitoring system would not alarm and consequently the PBSVS will not be actuated (i.e., the As a result, analyses were RBNVS continues to operate). performed assuming either RBSVS or RBNVS system operation. Secondary containment discharge rates are 167 and 6500 percent / day for the RBSVS and RENVS cases, respectively. As a comparison case, a " puff" release over a short period of time (2 hours, as suggested by Regulatory Guide 1.25), has been analyzed. Although thir is not a design basis case, it is useful to compare it with the two HVAC cases, Results for all three cases (RBSVS, RBNVS, and puff release) are given in the following sections. 15.1.36.6 Analysis of Effects and Consequences 15.1.36.6.1 Evaluation Methods The analytical methods and associated assumptions used to (~N evaluate the consequences of this accident are consistent

SHORERAM DSAR h\m- 15.1.36.6.1.1 Methods, Assumptions, and Conditions The assumptions used in the analysis of this accident are listed below:

1. The fuel assembly is dropped from the maximum height allowed by the fuel handling equipment.
2. The entire amount of potential energy, referenced to the top of the spent fuel racks, is available for application to the fuel assemblies involved in the accident. This assumption neglects the dissipation of some of the mechanical energy of the falling fuel assembly in the water above the racks and requires the complete detachment of the assembly from the fuel hoisting equipment. This is possible if the fuel assembly handle, the fuel grapple, or the grapple cable breaks.
3. None of the energy associated with the dropped fuel assembly is absorbed by the fuel materici (uranium dioxide).

15,1.36.6.1.2 Results and Consequences I ((~m) 15.1.36.6.1.2.1 Fuel Damage _ The analysis of USAR Section 15.1.36.5.1.2.1 applies to this accident. In that section of the USAR, it was assumed that 125 fuel rods would fail as a resultThe of dropping same the assumption fuel assembly into the reactor vessel. is applied here. 15.1.36.6.1.2.2 Fission Product Release From Fuel Fission determinedproduct from releases the 1989 for the fuel inventory in handling accident are l Table 12.2-1. Specifically, it is seen that only Kr-85 is of any The only significance with respect to gaseous releases. other gaseous isotope in this table is H-3, which wouldUsing the add, at most, 0.1% to the skin dose from Kr-85. above number of failed rods, and the assumptions given in Regulatory Guide 1.25, the quantity of Kr-85 released, is as follows: Release = 1.56E+03Ci x 125 damaged rods 62 rods / bundle x 560 bundles in core x 1.5 radial peaking factor x 30% in gap = 2.52 Ci (( 15-9 Rev. 3 July 1991

SHOREHAM DSAR- '\ 15.1.36.6.1.3 -Radiolocical Effects Offsite Radiological exposures have been evaluated for the meteorological conditions, parameters, and assumptions given in Table' 15.1.36-1. The results are given in Table 15.1.36-2. Control Room Because the amount of radioactivity' released is so small, the control room air intake monitors will not alarm and are not required. The control room HVAC system will continue to function in its normal operating mode. The resultant whole body and skin 30-day integrated doses are, at most, 9.59E-08 and 2.0BE-04 mrem, respectively, well below the 10CFR50 GDC 19 limits. Discussion It is seen in Table 15.1.36-2 that the (0-2 hour) EAB and (0-30 day) LPZ integrated doses are many orders of magnitude below 10CFR100 guidelines. Results are graphically shown in Figure 15.1.36-1. Furthermore, the maximum (t=0) dose rates (whole body and skin) are very low and, with the exception of the RENVS case, below Technical Specifications. This indicates that the HVAC system in use in the reactor building has no meaningful effect on radiological consequences to members of the public during a fuel handling accident with the present fuel source terms. 15.1.36A Worst Case Fuel Damace Event Scenario Several " worst case", extremely conservative scenarios were examined. Specifically, for the three reactor building HVAC cases analyzed in Section 15.1.36.5 (RBSVS operating, RBNVS operating, and puff release), instead of assuming the gap activity from 125 fuel rods is released (2.52 Ci Kr-85), it is assumed that all gaseous activity from the entire core This in the spent fuel pool is released (1.56E+03 Ci Kr-85). can only occur if all the fuel is postulated to be mechanically damaged and there is a complete release of gasecus isotopes. The assumption of a complete release of the-gaseous' inventory is also very conservative with respect to the Regulatory Guide 1.25 assumption of.a 30% release fraction given the low burnup condition of Shoreham spent fuel. Doses and dose rates are thus a factor of 617 higher than for the corresponding Regulatory Guide 1.25 cases. 15-10

Results are graphically shown in Figure 15.1.36A-1. Dose rates for the postulated worst case scenario are above current ODCM limits, but the duration of l

                -the-high dose rates in the RBNVS and puff release cases is quite short (two hours or less) .

OPERATIONAL SATETY  : i I.A.1.1 Shift Technical Advisor i NRC Position Each licensee shall provide an on-shift technical advisor to the  ! shift supervisor. The shift technical advisor (STA) may serve i more than one unit at a multi-unit site if qualified to perform ' the advisor function for the various units.  ! The STA shall have a bachelor's degree or equivalent in a  ; scientific or engineering discipline and have received specific  ; training in the response and analysis of the plant for transients [ and accidents. The STA shall also receive training in plant i design and layout, including the capabilities of instrumentation j and controls in the control room. The licensee shall assign i normal duties to the STAS that pertain to the engineering aspects of assuring safe operations of the plant, including the review  ! and evaluation of operating experience. [ h g- LILCO Position i

            ~

Under the conditions of the LILCO and New York State Shoreham settlement the plant is shutdown and defueled. STA staffing is therefore not required. [ I.A.1.2 Shift Supervisor Administrative Duties t i NBC Position _  ; i Review the administrative duties of the shift supervisor and delecate functions that detract from or arc subordinate to the ' management responsibility for assuring safe operation of the plant to other personnel not on duty in the control room.

1. The highest level of corporate management of each licensee  !

shall issue and periodically reissue a management directive that emphasizes the primary management responsibility of the  ; shift supervisor for safet operation of the plant under all i l conditions on his shift and that clearly establishes-his i command duties. 2 Plant procedures shall be reviewed to assure that the duties, responsibilities, and authority of the shift supervisor and ( l control room operators are properly defined to effect the  ! establishment of a definite line of command and clear I delineation of the command decision authority of the shift - supervisor in the control room relative to other plant l managment personnel. Particular emphasis shall be placed on i the following: }

SHORERAM DSAR {'

a. The responsibility and authority of the shift supervisor shall be to maintain the broadest perspective of operational conditions affecting the safety of the plant as a matter of highest priority at all timos when on duty in the control room. The principle shall be reinforced that the shift supervisor should not become totally involved in any single operations in times of emergency when multiple operations are required in the control room. -
b. The shift supervisor, until properly relieved, shall remain in the control room at all times during accident situations to direct the activities of control room operators. Persons authorized to relieve the shift supervisor shall be specified.
c. If the shift supervisor is temporarily absent from the control room during routine operations, a lead control room operator shall be designated to assume the control room command function. These temporary duties, responsibilities, and authority shall be clearly specified.
3. Training programs for shift supervisors shall emphasize and reinforce the responsibility for safe operation and the O management function that the shift supervisor is to provide for assuring safety.
4. The administrative duties of the shift supervisor shall be reviewed by the senior officer of each utility responsible for plant operations. Administrative functions that detract from or are subordinate to the management responsibility for assuring the safe operation of the plant shall be delegated to other operations personnel not on duty in the control room. ,

LILCO Position In lieu of a shift Supervisor SNPS uses a Watch Engineer. The administrative duties are minimized by the plant being shutdown and defueled with some systems being preserved / protected. Additionally, the administrative duties have little effect on safe operation of the plant. See the USAR for additional information. A Corporate Management Directive that emphasizes the primary t management responsibility of the Watch Engineer for the safe operation of the plant under all conditions is issued by the Assistant Vice President, Nuclear Operations annually.

Operation, Startup, or Hot Shutdown, respectively), the minimum shift crew shall include two licensed senior reactor operators (SRO), one of whom shall be designated as the shift supervisor,  : two licensed reactor operators (RO), and two unlicensed auxiliary l operators (AO). For a multi-unit station, depending upon the station configuration, shift staffing may be edjusted to allow  : credit for licensed senior reactor operators and licensed reactor l

As noted above, this individual may serve as relief operator for each unit being operated from that control room, provided he holds a current license for each unit.
f. Auxiliary (non-licensed) operators shall be properly '

qualified to support the unit to which assigned.

g. In addition to the staffing requirements stated above, shift crew assignments during periods of core alterations shall include a licensed senior reactor operator (SRO) to directly supervise the core alterations. This licensed 1 senior reactor operator may have fuel handling cuties but ';

shall not have other concurrent operational duties. Licensees of operating plants and applicants for operating licensees shall include in their administrative procedures

 -r-     (required by licence conditions) provisions governing required shift staffing and movement of key individuals about the plant.

d' l These provisions are required to assure that qualified plant personnel to man the operational shifts are readily available in the event of an abnormal or emergency situation. These administrative procedures shall also set forth a policy, . the objective of which is to operate the plant with the required  ! staff and develop vorking schedules such that use of overtime is avoided, to the extent practicable, for the plant staff who perform safety-related functions (e.g., senior reactor operators, , reactor operators, health physicists, auxiliary operators, I&C  ! technicians and key maintenenance personnel). ! IE Circular No. 80-02, " Nuclear Power Plant Staff Work Hours,' , dated February 1, 1980 discusses the concern of overtime work for members of the plant staff who perform safety-related functions. j The staff recognizes that there are diverse opinions on the amcunt of overtime that would be considered permissible and that there is a lack of hard data on the effects of overtime beyond the generally recognized normal 8-hour working day, the effects of shift rotation, and other factors. NRC has initiated studies I in this area. Until a firmer basis is developed on working hours, the administrative procedures shall include as an interim measure the following guidance, which generally follows that of IE Circular No. 80-02, in the event that overtime must be used (excluding extended periode of shutdown for refueling, major maintenance or major

Where useful improvements can be achieved, it l 1s expected that this group will develop and present detailed  ! recommendations to corporate management for such things as j revised procedures or equipment modifications.  :

                   ' Another function of the ISEG is to maintain surveillance of plant                            j operations and maintenance activities to provide independent                                  ;

verifications that these activities are performed correctly and i that human errors are reduced as far as practicable. ISEG will i then be in a position to advise utility management on the overall  ! quality and safety operations. ISEG need not perform detailed audits of plant operations and shall not be responsible for i sign-off functions such that it becomes involved in the operating  ! organization. The new ISEG shall not replace the plant operations review committee (PORC) and the utility's independent review and audit  ! group as specified by current staff guidelines (Standard Review l Plan, Regulatory Guide 1.33, Standard Technical Specifications). { Rather, it is an additional independent group of a miniraum of  ; five dedicated, full-time engineers, located onsite, but l reporting offsite to a corporate official who holds a high-level, i technically oriented position that is not in the management chain l for power production. The ISEG will increase the available >

    ~

technical expertise located onsite and will provide continuing, { systematic, and independent assessment of plant activities.  ; Integrating the Shift Technical Advisors into the ISEG in some way would be desirable in that it could enhance the group's  ! contact with and knowledge of day-to-day plant operations and  ! provide additional expertise. However, the shift technical l adviser on shift is necessarily a menter of the operating staff  ! and cannot be independent of it. It is expected that the ISEG may interface with the quality assurance (QA) organization, but preferably should not be an integral part of the QA organization. The functions of the ISEG require daily contact with the operating personnel and continued access to plant facilities and records. The ISEG review functions can, therefore, best be carried out by a group physically located onsite. However, for utilities with multiple sites, it may be possible to perform portions of the independent, safety assessment function in a centralized location for all the utility's plants. In such cases, an onsite group still is required, but it may be slightly smaller than would be the case if it were performing the entire f independent safety assessment function. Such cases will be reviewed on a case-by-case basis. AT this time, the requirements for establishinc an ISEG is being applied only to applicants for operating licenses in accordance

LIbCO does not have an ISEG. The functions of an ISEG do not apply to shutdown and defueled reactor which will not be operated.  ; I.C.1 Guidance for the Evaluation and Development of Procedures  ; for Transients and Accidents  ; NRC Position In letters of September 13 and 27, October 10 and 30, and November 9, 1979, the Office of Nuclear Reactor Regulation required licensees of operating plants, applicants for operating  ; licenses n' 'dcensees of plants under construction to perform

  • l analyses of taansients and accidents, prepare emergen-" procedure quidelines, upgrade emergency procedurcs, including ; :edures for operating with natural circulation conditions, anu to conduct ,

fr~N operating retraining (see also Item I.A.2.1). Emergency i ( ,) procedures are required to be consistent with the actions  ; necessary to cope with the transients and accidents analyzed. Analyses of transients and accidents were to be completed in , early 1980 and implementation of procedures and retraining were t to be completed 3 months after emergency procedure guidelines were established; however, some difficulty in completing these requirements has been experienced. Clarification of the scope of the task and appropriate schedule revisions are being developed. In the course of review of these matters on Babcock and Wilcox  : (b&W)-designed plants, the staff will follow up on the bulletin and orders matters relating to analysis methods and results, as listed in NUREG-0660, Appendix C (see Table C.1, items 3, 4, 16, , 18, 24, 25, 26, 27; Table C.2, items 4, 12, 17, 18, 19, 20; and Table C.3, items 6, 35, 37, 38, 39, 4*, 47, 55, 57). Based on staff reviews to date, there appear to be some recurring r deficiencies in the guidelines being developed. Specifically, the staff has found a lack of justification for the approach used , (i.e., symptom , event , or function-oriented) in developing diagnostic guidance for the operator and in procedural ' development. It has also been found that although the guidelines take implicit credit for operation of many systems or components,  ; they do not address the avilaability of these systems under expected plant conditions nor do they address corrective or e alternative actions that should b perforned to mitigate the event should these systems or components fail.

  !{ }

i

SHOREHAM DSAR I ) The analysis conducted to date for guideline and procedure development contain insufficient information to assess the extent to which multiple failures are considered. NUREG-0578' concluded that the single-failure criterion was not considered appropriate for guideline development and called for the considreation of multiple failures and operator errors. Therefore, the analyses that support guideline and procedure development should consider the occurrences of multiple and consequential failures. In general, the sequence of events for the transients and accidents and inadequate core cooling analyzed should postulate multiple f ailures such that, if the f ailures were unmitigated, conditions of inadequate core cooling would result. Examples of multiple failure events include:

1. Multiple tube rupture in more than one steam generator and tube rupture in more than one steam generators  ;

i

2. Failure of main and auxiliary feedvaters i
3. Failure of high-pressure recctor coolant makeup system; \
4. An anticipated transient without scram (ATWS) event following a loss of offsite power, stuck-open relief  !

valve or safety relief valve, or loss of main feedwater; I () 5. Operator errors of omission or commission. , The analyses should be carried out far enouch into the event to  ! assure that all relevant thermal / hydraulic /neutronic phenomena r are identified (e.g., upper head voiding due to rapid cooldown, i i steam generator stratification). Failures and operator errors during the long term cooldown period should also be addressed. The analyses should support development of guidelines that define j a logical transition from the emergency procedures into the  ; inadequate core cooling procedure including the use of I instrumentation to identify inadequate core cooling conditions, i Fationale for this transition thould be discussed. Additional i information that should be submitted includes:

1. A detailed description of the methodology used to develop I the guidelines; [

Associated control function diagrams, sequence-of-event i 2. diagrams, or others, if used; .

3. The bases for multiple and consequential failure ,

considerations;  ;

 ,         4. Supporting analysis, including a description of any computer codes usea;

f SHOREHAM DSAR i () 5. A description of the applicability of any generic results to plant-specific applications. f l owners' group or vendor submittals may be referenced as  ; aporopriate to support this reanalysis. If owners' group or vendor submittals have already been forwarded to the staf f for , review, a brief description of the submittals and justification l of their adequacy to support guideline development is all that is  ! required. l Pending staff approval of the revised analyais and guidelines, the staff will continue the pilot monitoring of emergency , procedures described in task action plan Item I.C.8 (NUREG-0660). . For PWRs, this will involve review of the loss-of-coolant,  : steam generator-tube rupture, loss of main feedwater, and  ! inadequate core cooling procedures. The adequacy of each PWR  ! vendor's guidelines will be identified to each NTOL during the  ! emergency procedure review. Since the analysis and guidelines i submitted by the General Electric Company (GE) owners' group that i comply with the requirements stated above have been reviewed and i approved for trail implementation of six plants with applications l for operatinc licenses pending, the interim program for BWRs will i consist of trial implementation on these six plants. l t Followine approval of analysis and guidelines and the pilot ' monitoring of emergency procedures, the staff will advise all licensees of the adequacy of the guidelines for application to  ! their plants. Consideration will be given to human factors engineering and system operational characteristics, such as i information transfer under stress, compatibility _with operator i training and control room design, the time required for component i and system response, clarity of procedural actions, and centrol room personnel interactions. When this determination has been made by the staff, a long-term plan for emergency procedure  ; review, as described in task action plan Item I.C.8, will be made available. At that time, the reviews currently being conducted f on NTOLs under Item I.C.8 will be discontinued, and the review  ! required or applicants for operating licenses will be as  ! described in the long-term plan. Depending on the information , submitted to support development of emergency procedures for each  : reactor type or vendor, this transition may take place at  ! different times. For example, if the GE quidelines are shown to l be effective on the six plants chosen for pilot monitoring, the j long-term plan for BWRs may be complete in early 1981. Operating  : plants and applicants will then have the option of implementing  : the long-term plan in a manner consistent with their operating  ! schedule, provided they meet the final date required for  ; implementation. This may require a plant that was reviewed for  ; an operating license under Item I C.9 to revise its emergency i

              <          procedures again prior to the f2ual implementation date for Item I.C.B. The extent to which the long-term program will include                                                                    .,

review and approval of plant-specific procedures for operating  ! plants has net been established. Our objective, however, is to  !

SilOREllAM DSAR  ; minimize the amount of plant-specific procedure review and  ; approval required. The staff believes this objective can be acceptably accomplished by concentrating the staff review and approval on generic guidelines. A key element in meeting this  ; objective is use of staff-approve ( generic guidelines and j guideline revisions by licensees to develop procedures. For this approach to be ef f ective, it is imperative that, once the staf f has issued approval of a guideline, subsequent revisions of the guideline should not be implemented by licensees until reviewed and approved by the str.ff. Any changes in plant-specific , procedures basud on unapproved guidelines could constitute an  ! unreviewed cafety issue under 10CTR50.59. Deviations from this approach on a plant-specific basis would be acceptable provided the basis is submitted by the licensee for staff review and ' approval. In this caso, deviations from generic guidelines { should not be implemented until staf f approval as formally i ' received in writing. Interim implementation of analysis and procedures for small-break loss-cf-coolant accident and inadquate core cooling should remain on the schedule contained in l NURIG-0578, Eecommendation 2.1.9.

Low-power and power-ascension test and emergency procedures will not be used at Shoreham. I.C.8 Pilot Monitorino of Selected Emeroency Procedures For Near-Term Operatino License Applicants NRC Position Correct emergency procedures as necessary based on the NRC audit of selected plant emergency operating procedures (e.g., small pg break loss-of-coolant accident, loss of feedwater, restart of N) engineered safety features following a loss of ac power and steam-line break).

SHOREHAM DSAR ([% LILCO Position The generic guidelines prepared by the BWR Owners' Group and approved by the NRC for trial implementation at the Shoreham Nuclear Power Station have been. incorporated into the Shoreham Emergency Operating Procedures (refer to NUREG-0737 Item I.C.1). The completed procedures have received an extensive in-house review, and were subjected to simulator verification. The verified procedures were submitted for NRC review. Any comments or corrections found necessary as a result of the NRC audit were evaluated and implemented, as appropriate. This item was closed in Section 3.1.1 of Inspection Report 83-09. I.D.1 Control Room Desion Reviews NRC Position In accordancv with Task Action Plan I.D.1, Control Room Design Reviews (NUREG1-06 6 0 ) , all licensees and applicants for operating licenses will be required to conduct a detailed control-room design review to identify and correct design deficiencies. This detailed control-room design review is expected to take about a year. Therefore, the Office of Nuclear Reactor Regulation (NRR) requires that those applicants for operating licenses who are unable to complete this review prior to issuance of a license make preliminary assessments of their control rooms to identify significant human factors and instrur..entation problems and establish a schedule approved by NRC for correcting deficiencies. These applicants will be required to complete the more detailed control room reviews on the same schedule as licensees with operating plants. NRR is presently developing human engineering guidelines to assist each licensee and applicant in performing deteiled control-room review. A draft of the guidelines has been published for public comment as NUREG/CR-1580, " Human Engineering Guide to Control Room Evaluation." The due date for comments on this draft document was September 29, 1980. NRR will issue the final version of the guidelines as NUREG-0700, by February 1981, after receiving, reviewing, and incorporating substantive public comments from operating reactor licensees, applicants for operating licenses, human factors engineering experts, and other interested parties. NRR will issue evaluation criteria, by July 1981, which will be used to judge the acceptability of the detailed reviews performed and the design rodifications implemented. Applicants for operating licenses who will be unable to complete the detailed control-room design review prior to issuance of a license are required to perform a preliminary control-room design assessment to identify significant human factors problems. Applicants will find it of value to refer to

 '-          audit. The NRR onsite review / audit will be on a schedule consistent with licensing needs and will emphasize the following aspects fo the control room:
1. The adequacy of information presented to the operator to reflect plant status for normal operation, anticipated operational occurrences, and accident conditions;
2. The. groupings of displays and the layout of panels;
3. Improvements in the safety monitoring and human factors enhancement of controls and control displays;
4. The communications from the control room to points outside the control room, such as the onsite technical support center, remote shutdown panel, offsite telephone lines, and to other areas within the plant for normal and emergency operation.
5. The use of direct rather than derived signals for the presentation of process and safety information to the operator;
6. The operability of the plant from the control room with
 .,r~s                   multiple failures of nonsafety-grade and nonseismic Q                        systems;
7. The adequacy of operating procedures and operator training with respect to limitations of the instrumentetion displays in the control room;
8. The categorization of alarms, with unique definition of safety alarms.
9. The physical location of the shift supervisor's office either adjacent to or within the control-room complex.

Prior to the onsite review / audit, NRR will require a copy of the applicant's preliminary assessment and additional information which will be used in formulating the details of the onsite review / audit.

II.B.2 Plant Shielding to Provide Access to Vital Areas and Protect Safety Equipment for Post-Accident Operation NRC Position The NRC position on the above is as given in the Shoreham USAR. LILCO Position In a fashion similar to the Shoreham USAR, LILCO has determined that the only areas after an accident where access may be needed are the Radwaste and Main Control Rooms and the Technical Support Center (TSC) full-time, and the Reactor Building refueling deck part-time. The basis of this is that, as seen in Chapters 11 and 15 of the DSAR, the only design basis events which remain credible are the Fuel Handling Accident (FRA) as described in Regulatory Guide 1.25, and the Liquid Radwaste Tank Rupture Accident. As discussed in Chapters 15 and 11, respectively, neither of these involve the release of large goantities of radioactivity, and thus there is no need The for the Post other Accident areas suggested

() Sampling and Analysis Facility (PASF). as vital post accident in NUREG-0737 do not apply for Shoreham or are not needed, for the reasons given in Section II.B.2 of the USAR. Furthermore, systems such as the hydrogen recombiner are as clearly no longer required in the defueled condition, documented in Chapter 6 of the DSAR. Source Term and Results The radioactive source terms (quantities and source distributions) for the design basis accidents are described in Section 11.2 for the Liquid Radwaste Tank Rupture Accident, and in Chapter 15.1.36 for the FHA (and Worst Case Fuel Damage Accident). Because the cubicles where a Liquid Radwaste Tank Rupture Accident could occur are exhausted to a process air header, which is then processed through a filter train before release through on the station vent, the postulated accident would have no affect general Radwaste Building habitability. Specifically, the Radwaste Control Room would be unaffected, since it is well For 1solated from the cubicles where the accident could occur. details, see Section 9.4.3 of the USAR. For the FHA and Worst Case Fuel Damage Accidents, the

In the short term, the teams are making an integrated assessment of licensee, local, and State capabilities and interfaces based on: (a) a review of existing plans and a meeting in the site area to communicate upgraded criteriaThis                                 and to identify -               '$censees the areas requiring improvements.

includes an opportunity for expression of concerns by the public through an open mehting. An objective of the teams is to help improve working relationships and communications concerning emergency plan development among all parties. The criteria being used by the NRC teams reflect a number of the recommendations made as a result of the TMI-2 accident by the President's Commission and the NRC Special Inquiry Group; and (b) a review of upgraded licensee, local, and State plans submitted by the licensee after the site visit is summarized in a safety evaluation report. This includes an identification of areas requirina improvement, a schedule for implementation of the improvements, and a specification of any required interim measures. The review of upgraded plans encompasses the points in SECY-19-450 and reflects any input from the Federal Regional Advisory Committees (RAC). Items on local or State plans requiring improvement to meet the upgraded criteria of NUREG-0654 but which are adequate to meet the essential planning elements of (' "KRC Guide and Checklist," NUREG-75/111, and Supplement 1 (_)g thereto, are not being required for issuance of licenses for low-power testing. The above actions are in progress and will be completed in FY 1980. In the longer term, beginning in FY 1981, an integrated assessment of the implementation of the plans will be performed. This assessment will take into account comments and revices by the RAC as a result of State plan concurrence efforts, including critiques of energency exercises. The results of the Office of Inspection and Enforcement (IE) special team efforts to evaluate Licensee health physics procrams during 1980-81 will be factored into the review. This longer term review of emergency preparedness will consist of three parts: (a) a review of implementing procedures, including inplant and offsite personnel and equipment. The review of these procedures will be done by the team. Subsequently, periodic reviews and inspections will be performed by IE; (b) observing and critiquing exercises involving licensee, local, and State capabilities; and (c) observing and critiquing exercises involving licensee, local, State and Federal capabilities. For new operating license applicants, this must be completed before full-power licensing and within about five years for operating reactorc.

3. The following information regarding TSC habitability:

As presently designed, the SNPS TSC meets the habitability criteria of GDC 19, for all credible design basis accidents (DBAs) envisioned with the fuel in the pool. The DBA on which this conclusion is based is the fuel handling accident (FRA), as described in detail in DSAR Section 15.1.36. Because the l accident releases are so low, it is (conservatively) assumed that ' the TSC's HVAC system is not isolated (i.e., 7000 cfm of unfiltered intake and exhaust continues throughout the accident). > A conservative, ground-level X/0 to the TSC intake is assumed, 7.86E-04 seconds per cubic meter.

However, due to the small quantity of radioactivity released during the design basir accident (the fuel handling accident) , the control room's remote intakes and standby charcoal filtration system are no longer required to meet General Design Criteria 19.      Doses, assuming the control room's HVAC system continues to function as during normal operation, are indicated in Chapter 15 of the DSAR.

System Desien The design of the control room HVAC system is as described in DSAR Section 9.4.1. As stated above, the remote intakes and the Inlet duct standby filtration system are no longer required.As such, instrumentation is no longer required as well. discussion of these items in USAR Section III.D.3.4 no longer applies. During the design basis accident, the control room EVAC system will continue to function as during normal plant j operations.
