The reserve station service transformers step down the offsite power from 115 to 13.8 and 4.16 kV, and provide two independent offsite power sources for the unit auxiliary power distribution system.The auxiliary boiler transformer steps down the offsite power from 115 to 13.8 and 4.16 kV.Its 13.8-kV winding supplies power to the auxiliary boiler and associated equipment; the 4.16-kV tertiary winding provides a backup source for the emergency 4.16-kV buses.The unit auxiliary power distribution system feeds all unit auxiliary loads through 13.8-kV switchgear, 4.16-kV switchgear, 600-V load centers, 600-V motor control centers, and various ac and dc distribution panels.The system is divided into nuclear nonsafety-related and nuclear safety-related systems.The nuclear nonsafety-related auxiliary power distribution system feeds all non-Class 1E unit auxiliary loads.Under normal plant operating conditions, it is energized from the normal station service transformer.
During startup and normal shutdown conditions, it is energized from offsite power sources thxough reserve station service transformers.
A normal 125-V dc system, consisting of batteries, battery chargers, and distribution panels, provides a reliable source of power for protection, control, and instrumentation loads and dc motors under normal and emergency conditions of the plant.A+24-V dc system provides a reliable source for the neutron monitoring system.The nuclear safety-related auxiliary power distribution system supplies all Class 1E unit auxiliary loads.This system is divided into three independent divisions.
Division I and Division II are independent redundant divisions and supply all nuclear safety-related auxiliary loads except the high pressure core spray (HPCS)system.The HPCS system and related equipment are supplied by Division III.All three divisions are normally energized from the offsite power sources through reserve station service transformers.
The auxiliary boiler transformer can be connected manually to act as a backup source for either the Division I or Division II supply.Each of the three divisions of the nuclear safety-related auxiliary power distribution systems has its own independent standby diesel generator.
In the event of a LOCA and/or 1.2-'19 Nine Mile Point Unit 2 FSAR loss of offsite power, each division is energized from its own standby diesel generator.
A 125-V emergency dc power system feeds all safety-related dc protection, control, and instrumentation loads and safety-related dc motors under normal operation of the plant as well as during emergency conditions.
The system is divided into three independent divisions each consisting of its own battery, primary and backup battery chargers, switchgear, motor control centers, and distribution panels.Each division feeds the dc loads associated with the corresponding divisions of the nuclear safety-related auxiliary power'distribution system.Chapter 8 describes the electrical power system in detail.1.2'.2 Nuclear System Process Control and Instrumentation Reactor Manual Control S stem The reactor manual control system (RMCS)provides the means by which control rods are positioned from the control room for power control.The system operates valves in each hydraulic control unit, to change control rod position.One control rod can be manipulated at a time.The RMCS includes the logic that restricts abnormal control rod movement (rod block)under certain conditions as a backup to procedural controls.Recirculation Flow Control S stem During normal power operation, a variable position discharge valve is used to control flow.Adjusting this valve changes the coolant flow rate through the core and thereby changes the core power level.The system can automatically adjust the reactor power to the load change by adjusting the electrical power supply.Neutron Monitorin S stem The neutron monitoring system (NMS)'s a system of incore neutron detectors and out-of-core electronic monitoring equipment.
The system provides indication of neutron flux, which can be correlated to thermal power level for the entire range of flux conditions that can exist in the core.The source range monitors (SRMs)and the intermediate range monitors (IRMs)provide flux level indications during reactor startup and low-power operation.
The.local power range monitors (LPRMs)and average power range monitors (APRMs)allow assessment of local and overall flux conditions during power range operation.
The traversing incore probe (TIP)system provides a means to calibrate the 1.2-20

Unit 2 also complies with this regulatory guide as described in Chapter 17 of the FSAR.Regulatory Guide 1.30, Rev.0, endorses IEEE Stan-dard 336-1971.Unit 2 Specification E061A, Electrical Installation, invokes IEEE Standard 336-1977, which is more conservative than IEEE Standard 336-1971.Section 3 of IEEE-336 addresses the requirements for preinstallation verification of material and equipment.
It also states that"it is not intended to duplicate inspections but, rather to verify that items are in satisfactory condition for installation." Preinstallation verification includes the following:
1.Identification of materials and equipment.
2.Availability of procedures, instruction manuals, and special work instructions.
3.Review of records of storage and preventive maintenance measures.4.Visual examination of materials and equipment.
to ensure physical integrity.
All these required verifications are addressed by the SWEC QA program for receipt, storage, and preventive maintenance inspections.
These inspections meet the intent of IEEE-336, Amendment 26 31 of 169 May 1986

In the case of control and instrument circuits, a combination of two interrupting devices actuated by fault current have been used to isolate nonClass 1E circuits from Class 1E circuits.Both of these devices are Class 1E, and both of.them are coordinated with the main breaker upstream so that a failure of a nonClass 1E device or circuit will not affect any Class lE device or system.Any circuit breakers as-sociated with this redundant protection will be tested during each refueling outage.Regulatory Position C.9 requires that cable splices in raceways be prohibited.
Splicing in electrical penetrations for termination is considered to be exempt from this requirement.
Regulatory Position C.10 requires that the cables be marked at 5-ft intervals.
This is a typographical error as con-firmed by the former Electrical, Instrument and Control Branch Chief of USNRC, T.A.Ippolito, on October 10, 1975,-and the NRC Power Systems Branch Section Leader, R.G.FitzPatrick, on October 30, 1980.The correct distance is 15 ft, which has been followed in Unit 2.The minimum separation distance from 600 V or less nonsafety-related conduit to safety-related open cable trays and cable in free air for any service level is 1 in.26 All cables used in Unit 2 are flame-retardant.
The cable trays are not filled above the side rails.The hazard, in this case, is limited to failure or faults internal to the nonsafety cables in rigid steel conduit.Unit 2 has deter-mined by analysis that 1-in separation between the Class 1E cable tray and nonClass 1E conduit provides adequate protec-tion for the Class lE cables in the open ladder tray in the Amendment 26 89 of 169 May 1986
 
Nine Mile Point Unit 2 FSAR TABLE 1.8-1 (Cont)event of any failure of the nonClass 1E cables in conduit.This has been established by tests with 600 V levels, as ex-plained later in this section.26 Aluminum sheath cables (ALS)used for low energy 120-V ac systems and 8-hr battery pack lighting systems, are con-sidered enclosed raceways.These cables have flame retard-ant, cross-linked polyethylene insulation, chlorosulphonated polyethylene jacket, and polypropylene fillers enclosed in a continuous, impervious aluminum sheath which provides adequate protection.
As such, the minimum separation between these cables and Class 1E raceways is 1 in.The minimum separation between any Class 1E raceway and any lighting cord for drops to the lighting fixtures shall be 1 in.These cords are of size 12 AWG and supply 120/208 V ac low energy in low density applications.
As such, 1-in separation provides adequate protection to the Class 1E cir-cuits in the event of a fault in any lighting cord.IZEE Standard 384-1974, Section 5.1.1.2, allows lesser separation distances than those specified in Sections 5.1.3 and 5.1.4, if established by analysis.Various tests have indicated that the following minimum separation distances between redundant Class lE cables and raceways, or between Class 1E and nonClass 1E cables and raceways, 600 V level and below, should be adequate to maintain independence of the redundant systems.NMPC also has verified these minimum separation distances by plant specific tests (Wyle Test Report No.47906-02, Electrical Separation Verification Testing).Cable tray to cable tray 10 in horizontal or 10 in vertical Cable tray to conduit Cable in free air to conduit Cable in free air to cable in free air 1 ln 1/2 in 10 in vertical or 10 in horizontal Cable in free air to cable tray 10 in vertical or 10 in horizontal Wrapped cable to unwrapped cable 0 in Conduit to conduit 1/2 in Amendment 26 89a of 169 May 1986

This is verified in the j et impingement evaluation where breaks are postulated at various elevations and azimuths.Additional investigation is only repetitive.
It is therefore concluded that this will not degrade the safety of the plant.Difference 2 Section B.l.c.l.d states that"if intermediate break locations cannot be determined by (b), (B.l.c.l.b) and (c), (B.l.c.l.c) above, two highest stress locations based on equation (10)should be selected." Unit 2 uses a reasonable basis which includes factors such as points of maximum stress intensity and/or cumulative usage factors;however, the points of maximum stress intensity are based on Equation (12)or (13).Discussion Since all postulated intermediate breaks require evaluation of Equations (12)and (13)and cumulative usage factors, it is reasonable to use these equations to determine points of maximum stress intensity.
This approach is conservative.
Difference 3 Section BE 1.c.4 states that"if a structure separates a high energy line from an essential component, the separating structure should be designed to withstand the consequences of the pipe break in the high energy line which produces the greatest.effect at the structure irrespective of the fact that the above criteria might not require such a break location to be postulated." Unit 2 design structures withstand the consequence of pipe breaks postulated at locations in accordance with Sections B.l.c.l, BE 1.c.2, and B.l.c.3.Discussion A systematic logical method must be used to evaluate the effects of pipe breaks in order to address a finite number of potential load cases.By assuming breaks at highly stressed locations and by requiring a minimum number of locations to be selected, a reasonable margin of safety will evolve.Requiring breaks to be postulated based on structural capability is not prudent and does not enhance the safety of the plant.Several points are: Amendment 1 3 of 4 April 1983 Nine Mile Point Unit 2 FSAR ATTACHMENT 1.9-14 (Cont)Pipe whip loadings are very sensitive to the distance over which unrestrained whip could occur, piping geometry, and break orientation.
An infinite number of cases would require consideration particularly if splits are arbitrarily postulated along the length of the pipe.Jet impingement does not have this problem since the load is distributed over a reasonable area.However, pipe whip requires evaluation of local effects, which is much more involved.2.'n excessive number of scab plates would be required on all structures which separate high energy and essential systems, thus causing an unreasonable number of scab plates to be installed.
3.By strengthening the weakest part of a structure, the next weakest part would then be the worst case.This is a perpetual cycle.Additional safety is not really obtained by evaluating the least likely events.Since pipe breaks themselves are extremely unlikely, it is reasonable to postulate them only at the higher stressed locations.
Additionally, all walls in the proximity of high energy systems are evaluated for a reasonable number of pipe breaks simply due to the number of breaks which must be postulated using the stress criteria.Amendment 1 4 of 4 April 1983 Nine Mile Point Unit 2 FSAR ATTACHMENT 1.9-29 STANDARD REVIEW PLAN 3.11, REVISION 2 ENVIRONMENTAL QUALIFICATION OF MECHANICAL AND EIECTRICAL EQUIPMENT Difference 1 The submittal of the environmental qualification document which demonstrates equipment environmental capability is not included.Discussion The environmental qualification document will be submitted and the FSAR amended accordingly prior to fuel load.Difference 2 Discussion of equipment qualification to a mild environment is not included.Discussion Definitive guidelines are not yet available from the NRC concerning equipment qualification in mild environment.
Difference 3 Coverage of mechanical equipment qualification is not.included.Discussion Current NRC direction indicates that formal mechanical equipment qualification guidelines may be issued in the future.The NRC has stated that no further requests for mechanical equipment qualification data will be made until the NRC has acceptance criteria upon which to evaluate them.When NRC guidelines are issued, the mechanical equipment qualification impact will be addressed.

Nine Mile Point Unit 2 FSAR ATTACHMENT 1.9-61 STANDARD REVIEW PEAN 9.5.1, REVISION 3, JUIY 1981 FIRE PROTECTION PROGRAM (FIRE PROTECTION SYSTEM)Deviations to BTP CMEB 9.5-1 Attached to Standard Review Plan 9.F 1 Fire Protection Pro ram Difference 1 Section C.l.c.(3)states that"the fire suppression system should be capable of delivering water to manual hose stations located within hose reach of areas containing equipment required for safe shutdown following the safe shutdown earthquake (SSE)." Discussion Unit 2 standpipe and hose connection design is in accordance with Appendix A (dated August 1976)to BTP 9.5-1 (dated May 1, 1976)and Appendix R to 10CFR50, and is not seismically qualified.
The design does not contemplate simultaneous earthquake and fire conditions; therefore, this requirement was not incorporated into the design.Further, justification is that Unit 2 is not in an area of high seismic activity.Difference 2 Section CD 5.a(3)(b)of Unit 2 design incorporates fire boot-type penetration seals (approximately 200 of 11,000 fire rated seals)for which temperature levels on the unexposed side reached 3930F during the acceptance test.27 Discussion Fixed combustibles potentially within close proximity have ignition temperatures of)500 F.Cables are generally installed in raceways (ice., conduit or cable trays).Difference 3 Section C.5.a(5)-Unit 2 fire doors, including fire doors in areas protected by automatic total flooding gas suppression systems, are administratively supervised to verify that they are in the closed position.Discussion Fire doors are maintained in the closed position.Additionally, fire doors in areas protected by automatic total flooding CO<systems are provided with CO2 activated door releases, in the event that the door is in Amendment 27 1 of 4 July 1986 Nine Mile Point Unit 2 FSAR ATTACHMENT 1.9-61 (Cont)the open position at the time"of CO<discharge.
Halon 1301 suppression systems are used in computer rooms and control rooms.Doors to these areas are inherently supervised by the occupants in the area, in addition to the"daily.inspection, to verify that the doors are in the proper'osition.Amendment 27 la of 4 July 1986 Nine Mile Point Unit 2 FSAR ATTACHMENT 1.9-61 (Cont)incorporate the use of open directional spray nozzles discharge an excessive amount of water in protected areas, requiring substantially larger drainage and processing capabilities than areas protected by sprinkler systems which minimize the potential for damage to safety-related structures and components.
Difference 7 Section C.5.g.(1)-Unit 2 emergency lighting capability is provided by means other than individual 8-hr battery supplies.2 Discussion Areas which must be manned during safe shutdown will be supplied with'8-hr battery packs for access and egress lighting.Difference 8 Section C.S.g.(3)-The Unit 2 emergency communications system is not independent of the plant communication system.Discussion Fixed emergency communications systems independent of normal plant communications systems are not necessary because: 1~The systems are connectible to uninterruptible power sources, which provide reliability during emergency conditions.
2~In case of total loss of power to all communication systems, the Sound Powered Communication (SPC)system can be utilized.3.The system is set up as described in Section 9.5'.4.The system and important components are supervised.
Difference 9 Section C.6.a.(3)-The fire detector spacing criteria for Unit 2 meet the intent of NFPA 72E.Discussion NFPA 72E recommends one detector per bay for beam depth greater than 8 in and bay width greater than Amendment 27 3 of 4 July 1986 Nine Mile Point.Unit 2 FSAR ATTACHMENT 1.9-61 (Cont)8 ft.NFPA 72E does not address beam depth greater than 8 in and bay width less than 8 ft.In this situation, the Unit 2 design incorporate's one detector for every other bay mounted on the bottom flange of structural steel..Difference 10 Section C.6.c.(4)-Unit 2 design does not cross connection to the service water firefighting capability post-SSE.Discussion Standpipes and hose connections for manual fire fighting are seismically supported in safety-related areas and in areas containing safety-related equipment.
The design bases do not contemplate simultaneous earthquake and fire conditions; therefore, this requirement was not incorporated into the design.Further justification is that, Unit 2 is not in an area of high seismic activity.Difference ll Section C.7.a.(1), part (c)-During normal operation, the Unit 2 design does not, incorporate the use of general area fire detection in the primary containment.
Discussion The Unit 2 containment is inerted during normal operation.
Difference 12 In general, Section C endorses the use of the National Fire Protection Association (NFPA)standards.
Unit 2 deviates from a number of these NFPA standards.
Discussion Each Unit 2 deviation to the NFPA standards is described and justified in Table 9.5-3.Amendment 27 July 1986 Nine Mile Point Unit, 2 FSAR ATTACHMENT 1.9-80 SRP DEVIATION WRITEUPS CHAPTER 16-TECHNICAL SPECIFICATIONS The information contained in Chapter 16 j.s preliminary and has not yet been modified to reflect NMPC policy and Unit 2 design.Therefore, an analysis to determine conformance to the SRP is not yet required.Amendment, 1 1 of 1 April 1983

i.e., annual by V.P.for operations Nine Mile Point Unit 2 Position Prior to fuel loa'ding and annually thereafter, the Vice President Nuclear Generation shall issue a management directive that emphasizes the primary management responsibility of the Station Shift Supervisor (SSS)for safe operation of the plant under all conditions on his shift and clearly establishes his command duties.Plant procedures are written to ensure that the duties, responsibilities, and authority of the SSS and other licensed control room operators are properly defined to affect the chain of command.In the future, administrative duties of the SSS will be reviewed annually after fuel load by the Vice President Nuclear Generation to ensure that such functions do not detract from safe plant operation.
SSS Res onsibilities The Station Shift Supervisor is in charge of all operations on his assigned shift.Under the general direction of the Supervisor Operations Nuclear, his function includes direction of shift activities, authorization of equipment releases for maintenance, ensuring that the plant is operated safely and within the license and technical specifications and ensuring that plant operations are conducted in accordance with approved procedures.
As*This requirement shall be met before fuel loading.See NUREG-0578, Section 22.1a, Item 4 and NRC letters of September 27, and November 9, 1979.Amendment 14 1.10-9 October 1984 Nine Mile, Point Unit 2 FSAR overall supervisor of operations for his shift, the Shift Supervisor shou'ld avoid becoming personally involved in the manipulative tasks or details of operation of any one portion of the plant so, that he may retain a comprehensive perspective of general station conditions at all times.In an emergency situation, however, should the Shift Supervisor choose to perform manipulative functions to ensure that the plant is in a safe condition, he shall, coordinate his actions with the Chief Shift Operator.Whenever he determines that the safety of the reactor is in immediate jeopardy or when operating parameters exceed any of the reactor protection circuit set points and automatic shutdown should but does not occur, he has the responsibility and the authority to order shutdown of the reactor, or to personally effect the shutdown.The Shift Supervisor shall sen'ior reactor operator license.uously present at the plant of his assigned shift hold an NRC He shall be contin-for the duration until properly Amendment 17 1.10-9a January 1985 Nine Mile Point Unit 2 FSAR The staff realizes that, the necessary knowledge and experience can be gained in a variety of ways.Consequently, credit for equivalent experience should be given to applicants for SRO licenses.Applicants for SRO licenses at a facility may obtain their 1 yr operating experience in a licensed capacity (Operator or Senior Operator)at another nuclear power plant.In addition, actual, operating experience in a position that is equivalent to a licensed Operator.or Senior Operator at military propulsion-reactors will be acceptable on a one-for-one basis.-Individual applicants must document this experience in their individual applications in sufficient detail so that the staff can make a finding regarding equivalency.
Applicants for SRO licenses who possess a degree in engineering or applicable sciences are deemed to meet the above requirement, provided they meet the requirements set forth in Sections A.l.a and A.2 in enclosure 1 in.the letter from H.R.Denton and all power reactor applicants and licensees, dated March 28, 1980, and have participated in" a training programequivalent to that of a'old Senior Operator Applicant.
The NRC has not imposed the 1-yr cold applicants for SRO licenses.work.on',a facility not yet.in programs are designed to supply experience not.available to them.Nine Mile Point Unit 2 Position experience requirement on Cold applicants are to operation; their training the equivalent of the The Upgrading of Operator Training and Senior Operator Training for Unit 2 is.being performed as described in Section 13.2 of the FSAR.This is also in accordance with the Site Administrative Procedures.
1.10-15 Nine Mile Point.Unit 2 FSAR I.A.2.3 ADMINISTRATION OF TRAINING PROGRAMS FSAR Cross Reference Section 13.2.1 NUREG-0737 Position Pending accreditation of training institutions, licensees and applicants for operating licenses will assure that training center and facility instructors who teach systems, integrated responses, transient, and simulator courses demonstrate SRO qualifications and are enrolled-in appropriate requalification programs.The above position is a short-term position.In the future, accreditation of training institutions will include review of the procedure for certification of instructors.,The certification of instructors may or may not.include successful completion of a Senior Operator examination.
The purpose of the examination is to provide the NRC with reasonable assurance during the interim period that instructors are technically competent.
The requirement is directed to permanent members of the training staff who teach'he subjects enumerated above, including members of other organizations who routinely conduct training at the facility.There is no intention to require guest lecturers who are experts in particular subjects (reactor theory, instrumentation, thermodynamics, health physics, chemistry; etc)to successfully complete a Senior Operator examination.
Nor do we intend to require a system expert, such as the Instrument and Control Supervisor teaching the rod control drive system to sit for a Senior Operator examination.
The use of guest lecturers should be limited.Nine Mile Point Unit 2 Position The qualification of the training instructors meets the requirements of this task, as described in Section 13.2 of the FSAR.1.10-16 Nine Mile Point Unit 2 FSAR I.A.3.1 REVISE SCOPE AND CRITERIA FOR LICENSING EXAMINATIONS
-SIMUZATOR EXAMS FSAR Cross Reference Section 13'.1 NUREG-0737 Position k Simulator examinations will be included as part of the licensing examinations.
The administration of simulator examinations will-be deferred for applicants whose facilities do not have simulators onsite as of October 1, 1980.These deferred simulator examinations will be initiated by October 1, 1981.The clarification provides additional preparation time for utility companies and the NRC to meet examination requirements as stated.A study is under way to consider how similar a nonidentical simulator should be for a valid examination.
In addition, present simulators are fully booked months in advance.Application of this requirement was stated on June 1, 1980 to applicants where a simulator is located at the facility.Starting October 1, 1981, simulator examinations will be conducted for applicants of facilities that do not have simulators at the site.NRC simulator examinations normally require 2 to 3 hr.Normally, two applicants are examined during this time period by two examiners.
Utility companies should make the necessary arrangements with an appropriate simulator training center to provide time for these examinations'referably these examinations should be scheduled consecutively with the balance of the'xamination.
However, they may be scheduled no sooner than 2 weeks prior to and not later than 2 weeks after the balance of the examination.
Nine Mile Point Unit 2 Position All new licensing examinations will utilize a control room ,simulator.
The simulator for Unit 2 has been ordered, and it is expected to be operational in January 1985.
Nine Mile Point Unit 2 FSAR I.B.1.2 INDEPENDENT SAFETY ENGINEERING GROUP FSAR Cross Reference Sections 13.4, 16.6.2 NUREG-0737 Position Each applicant for an operating license shall establish an onsite independent safety engineering group (ISEG)to perform independent reviews of plant operations.
The principal function of the ISEG is to examine plant operating characteristics, NRC issuances, Licensing Information Service advisories, and other appropriate sources of plant design and operating experience information that may indicate areas for improving plant safety.The ISEG is to perform independent review and audits of plant activities, including maintenance, modifications, operational problems, and operational analysis and to aid in the establishment of programmatic requirements for plant activities.
Where useful improvements can be achieved, it:is expected that this group will develop and present detailed recommendations to corporate management for such things as revised procedures or equipment modifications.
.-Another function of the ISEG is to maintain surveillance of plant operations and maintenance activities to provide independent verification that these activities are performed correctly and that human errors are reduced as far as practicable.
ISEG will then be in a position to advise utility management on the overall quality and safety of operations.
ISEG need not perform detailed audits of plant operations and shall not be responsible for signoff 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 quidelines (Standard Review Plan, Regulatory Guide 1.33, Standard Technical Specifications).
Rather, it is an additional independent group of a minimum of five dedicated, full-time engineers, located onsite but reporting offsite.to a corporate official who holds a high level, technically-oriented position that is not in the management chain 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 Amendment 23 1.10-18 December 1985 Nine Mile, Point Unit 2 FSAR Advisors (STAs)into the ISEG in some way would be desirable in that it could enhance the group's contact with the knowledge of day-to-day plant operations to provid'e additional expertise.
However, the STA on shift is necessarily a member of the operating staff and cannot be independent of it.It is expected that'he 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 independent safety assessment function.Such cases will be reviewed on a case-by-case basis.At this time, the requirement for establishing an ISEG is being applied only to applicants for operating licenses in accordance with Task I.B.1.2.The staff intends to review this activity xn about a year to determine its effectiveness and to see whether changes are required.Applicability to operating plants will be considered in implementing long-term improvements in organization and management for operating plants (Task I.B.l.l).Nine Mile Point Unit 2 Position An onsite independent safety engineering group (ISEG)will be established to perform independent reviews of plant operation.
The principal function of the ISEG'is to examine plant operating characteristics and the various NRC and industry licensing and service advisories, and to recommend areas for improving plant operations or safety.The ISEG will perform independent review of plant activities, including maintenance, modifications, operational concerns and analysis and make recommendations to the Supervi'sor Technical Support Nuclear.The Supervisor Technical Support Nuclear (or his designee)will present to the Operations Assessment Committee (OAC)and/or the Technical Superintendent the results of the analysis, including (when useful improvements can be Amendment 17 1.10-19 January 1985 Nine Mile Point Unit 2 FSAR achieved)detailed recommendations such as revised procedures or equipment modifications.
Presentations to the SORC are provided by the OAC (Section 13.4).The ISEG will observe plant operations and maintenance activities to determine that these activities are being performed properly and provide written recommendations (when useful improvements can be achieved).
The ISEG does not perform detailed (QA-type)audits and is not responsible for signoff functions associated with daily operational activities.
The ISEG is independent of the SORC and SRAB, but may make recommendations to these groups.26 The ISEG shall be composed of at least five dedicated, full-time engineers located onsite, assigned to Unit 2, who report to the Supervisor Technical Support Nuclear.Each shall have a bachelor's degree in engineering or related science and at least 2 years professional level experience in his field, at lease 1 year of which experience shall be in the nuclear field.The Supervisor Technical Support, Nuclear reports to the Superintendent Technical Services Nuclear who reports to the Technical Superintendent who is responsible for all technical support onsite.Although the Technical Department reports to the General Superintendent Nuclear Generation (who is responsible for operations), the Technical Department is independent from the direct operational supervision of the plant (that responsibility resides with the Station Superintendent)
~Additionally, the Technical Department has recourse to resolve safety concerns by addressing such concerns to either the SRAB or the Vice President Nuclear Engineering and Licensing.
Amendment 26 1.10-19a May 1986 Nine Mile Point Unit 2 FSAR Nine-Mile Point Unit 2 Position Unit 2 will utilize administrative and training procedures to implement op'crating experience feedba'ck to the plant staff..l.These procedures will: Clearly identify organizational responsibilities for review of operating experience, the feedback of pertinent-'nformation to operators and other personnel, and the incorporation of such information in training'and requalification training programs (Section 13.2.4.1.1, Item 9).2.Identify the administrative and technical review steps necessary to tianslate recommendations by the Operating Assessment Committee (OAC)into plant actions (e.g., changes to procedures and operating orders).Sections 13.4 and 1.10 provide information concerning the OAC.3.Identify the recipients of various categories of operating experience information (i.e., shift or supervisor, personnel) or otherwise provide means through which such information can be readily related to the job functions of the recipients (Section 13.2.4.1.3).
Provide means to ensure that affected personnel become aware of and understand information of sufficient importance so that this information should not wait for emphasis through routine training and retraining, standing orders or night orders.(For example, required reading assignments are made on an ongoing basis to address this concern.)5.Ensure that plant personnel do not routinely receive extraneous information on operating experience in such volume that it could obscure priority information.
6.Provide suitable, checks to ensure that correct information is conveyed to operators and other personnel.
7.Provide periodic audits to ensure that the feedback program functions effectively (e.g., training audits).Amendment 17 1.10-33 January 1985 Nine Mile Point Unit 2 FSAR Operating experience assessment is performed on an ongoing basis by the Technical Support.Group, OAC, and SORC as described in the administrative procedures.
The individuals involved review information from a variety of sources such as IE Bulletins, IE Information Notices, INPO reports, LERs, and vendor information letters, such as SILs.The feedback system provides for early notification of significant
:-information to operating personnel and management.
The evaluation process, specifically the OAC meeting, provides assurance that the information is correct and that unimportant and extraneous information does not impact overall proficiency.
Amendment 17 1.10-33a January 1985 Nine Mile Point Unit 2 FSAR 3.Improvements in the safety monitoring and human factors enhancement of controls and control displays.Communications from the control room to points out-side 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.Use of direct rather than derived signals for the presentation of process and safety information to the operator.6.Operability of the plant from the control room with multiple failures of nonsafety-grade and nonseismic systems.7.Adequacy of operating procedures and operator training with respect to limitations of instrumen-tation displays in the control room.8~Categorization of alarms, with unique definition of safety alarms.9.Physical location of the shift supervisor's office either adjacent to or within the control room complex.Prior to the onsite review/audit, the Office of Nuclear Reactor Regulation 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.
Nine Mile Point Unit 2 Position The Unit 2 project will utilize the guidance provided by the NRC Committee to Review Generic Requirements (CRGR)as stated in SECY 82-111.NMPC has performed a preliminary control room design review based on the BWR Owners Group program.The survey was structured with a team consisting of representatives from NMPC, other utilities, the NSSS supplier, and a human fac-tors consultant.
This group included licensed Senior Reac-tor Operators.
The review included panel instrumentation, hardware, and layout and design, annunciators.
The 1.10-39 Nine Mile Point Unit 2 FSAR preliminary review, was set, up to identify areas where poten-tial changes could be made in the PGCC shop prior.to ship-ment.to the site in early 1983.The final control room design review will be conducted during 1983 or 1984 based on the guidance of NUREG-0700.
The following paragraphs provide a description of this review.Pur ose and Sco e The purpose of the control room design review described is to 1)review and evaluate, the control room workspace, instrumentation, controls, and other equip-ment, from a human factors engineering point of view that takes into account, both system demands and operator capabilities; and 2)to identify, assess,.and implement con-trol room design modifications that improve control room man-machine interfaces.
The scope of the Unit 2 control room design review described covers the human factors en-gineering aspects of the completed control room.the following objectives:
To determine whether the control room provides the system status information,.control capabilities, feedback, and analytic aids necessary for control room operators to accomplish their functions effectively.
2.3.To identify characteristics of existing control room instrumentation, controls, other equipment, and physical arrangements that may detract from operator performance.
To analyze and evaluate the problems that could arise from discrepancies of Items 1 and 2, and to analyze means of correcting those discrepancies.
To define and put into effect a plan of action that applies human factors principles to improve control room design and enhance operator effectiveness.
Particular emphasis will be placed on improvements affecting control room design and operator perform-ance under abnormal or emergency conditions.
To integrate the control room design review with other areas of human factors inquiry identified as a result of TMI-related requirements.
1.10-40 Nine Mile Point.Unit 2 FSAR room is separated into a primary display and a secondary display.The secondary display is also utilized for main generator temperature monitoring.
At this time the nuclear data link (NDL)has not been defined by the NRC and no equipment has been procured for this purpose.Amendment, 3 1.10-46a June 1983 Nine Nile Point Unit 2 FSAR THIS PAGE INTENTIONALLY BLANK Amendment 3 1.10-46b June 1983 Nine Mile Point Unit 2 FSAR Criterion 2 The licensee shall establish an onsite radiological and chemical analysis capability to provide, within 3-hr time frame established above, quantification of the following:
Certain radionuclides in the reactor coolant and containment atmosphere that may be indicators of the degree of core damage (e.g., noble gases;iodines and cesiums, and nonvolatile isotopes);
2.Hydrogen levels in the containment atmosphere 3.Dissolved gases (e.g., H~), chloride (time allotted for analysis subject to discussion below), and boron concentration of liquids.'4.Alternatively, have inline monitoring capabilities to perform all or part of the above analyses.Clarification 2 A discussion of the counting equipment capabilities is needed, including provisions to handle samples and reduce background radiation to minimize personnel radiation exposures (ALARA).Also a procedure is required for relating radionuclide concentrations to core damage.The procedure should include: a.Monitoring for short-and long-lived volatile and non-volatile radionuclides (see.Vol.II, Part 2, pp., 524-527 of Rogovin report for further information).
b.Provisions to estimate the.extent of core damage based on radionuclide concentrations and taking into consideration other physical parameters such as core temperature data and sample location.2.Show a capability to obtain a grab sample, transport and analyze for hydrogen.3.Discuss the capabilities.
to sample and analyze for the accident sample species listed here and in Regulatory Guide 1.97, Rev.2.4.Provide a discussion of the reliability and maintenance information to demonstrate that the Amendment 7 1.10-64'a December 1983 Nine Mile Point Unit 2 FSAR selected on-line instrument is appropriate for this application.(See (8)and (10)below relative to back-up grab sample capability and instrument range and accuracy).
Position 2 Response: (2)The reactor coolant and containment atmosphere samples from the PASS can be analyzed for major fission product concentrations by gamma ray spectral analysis'he samples may be diluted by a factor of up to 10~to.obtain activities permitting isotopic analysis on a germanium crystal detector.The samples are handled using long tongs and lead brick shielding to reduce radiation exposure to a level as low as reasonably achievable.
The concentrations of Kr-85, I-131, Cs-137, and Xe-133 are corrected for dilution, decay, temperature, and pressure to the time of reac+or shutdown.The extent of fuel damage can then be determined directly from the figures provided in the plant emergency procedures.
Hydrogen levels in the containment, can be measured by the Containment Atmosphere Monitoring System.The hydrogen analyzer is environmentally qualified in accordance with Regulatory Guide 1.89 to operate satisfactorily following a LOCA.The hydrogen concentration is recorded in the main control room.Alternatively, a grab sample of the containment atmosphere can be obtained by the PASS and analyzed for hydrogen concentration by using a gas chromatograph.
Boron content of reactor coolant can be determined by analyzing the diluted reactor coolant sample by the carminic acid method.The sample is handled in the laboratory with long tongs and lead brick shielding to reduce radiation exposure.Total dissolved gas levels in the reactor coolant can be determined by measuring the pressure of the gas collected from a degassed sample of coolant.A sample of the dissolved gases can be obtained and analyzed for hydrogen or oxygen content using a gas chromatograph.

Nine Mile Point Unit 2 Position~The NRC has identified a total of 20 scenarios that could possibly lead to high pressure two-phase or liquid flow through the SRV.The Unit 2 project will provide the following means to resolve the NRC concerns: 1.Redundant Level 8 trip for RCIC (Events 4 and 9)2.Redundant Level 8 trip for HPCS (Events 5 and 10)3.Redundant nonsafety Level 8 trip to close the three feedwater control valves and two HPLF valves (Event 1)The tests and analyses described in Reference 1 verify the adequacy of safety relief valves (SRV)operation and the integrity of the SRV piping under expected liquid discharge conditions, and satisfy all requirements of NUREG-0737, Item IIELD.l.As discussed in Appendix A of Reference 1, for Dikkers valves, there are no material, dimensional or operational differences between the in-plant valves and the tested valves.Since the valves are identical, the test results for Dikkers valves are applicable to the corresponding in-plant valves.Reference 1.Analysis of Generic BWR Safety/Relief Valve Operability Test Results, NEDO-24988, Class I, October 1981.Amendment 7 1.10-69 December 1983 Nine Mile Point Unit 2 FSAR In a letter from D".G.Eisenhut of the NRC to C.V.Mangan of NMPC dated March 29, 1984, the Equipment Qualification Branch requested that NMPC provide additional information.concerning TMI Action Plan II.D.1.Following are the responses to each NRC question: uestion 1 A The test program utilized a rams head discharge pipe configuration.
Most plants utilize a.tee quencher configuration at the end of the discharge line.Describe the discharge pipe configuration used at your plant and compare the anticipated loads on valve internals in the plant configuration to the measured loads in the test program.Discuss the impact of any differences in loads on valve operability.
~Res ense Unit 2.utilizes a tee quencher at the end of the main steam SRV discharge line (SRVDL).The test program described in NEDE-24988-P used a rams head discharge device with test conditions simulating the shutdown cooling mode.The impact of the difference on valve operability is accounted for as follows:.Valve operability is affected by dynamic loads on valve internals.
The dynamic loads are governed by (a)back pressure of the SRV and (b)flow through the SRV.Higher back pressures and flow will produce higher dynamic loads.(a)In the test-.program, the SRV inlet pressure was equal to 250 psig.The Unit 2 reactor pressure during shutdown cooling'ode is approximately 135 psig.The maximum back pressure of the SRV is approximately 35 percent of the SRV inlet pressure;thus, the test program has qualified the SRV to.work with back pressure of about two times that of Unit 2.This provides adequate margin to offset the difference in using a tee quencher.(b)The test program has qualified the SRV with a rams head discharge device.The tee quencher allowed less flow (257 ibm/sec)than the rams head (260 ibm/sec)because it has-higher flow resistance.
Thus, operability of the SRV for Unit 2 SRVDL with a tee quencher will also be qualified.
Amendment 23 1.10-69a December 1985 Nine Mile Point Unit 2 FSAR Refer to the responses to Questions F421.21 and F421.23 for further information regarding the Unit 2 position.Refer to the response for Task II.F.1 for a discussion of incore thermocouples and to the response for Task I.D.l for Amendment 14 1.10-84a October 1984 Nine Mile Point Unit 2 FSAR THIS PAGE INTENTIONAjjY BIANK Amendment 14 1.10-84b October 1984 Nine Mile Point Unit 2 FSAR An investigation of the feasibility and contraindications of reducing challenges to the relief valves by use of the aforementioned methods should be conducted.
Other methods should also be included in the feasibility study.Those changes which are shown to reduce relief valve challenges without compromising the performance of the relief valves or other systems should be implemented.
Challenges to the relief valves should be reduced substantially (by an order of magnitude).
Failure of the power-operated relief valve (PORV)to reclose during the TMI-2 accident resulted in damage to the reactor core.As a consequence, relief valves in all plants, in-cluding BWRs, are being examined with a view toward their possible role in a small-break LOCA.The SRVs are dual-function pilot-operated relief valves that use a spring-actuated pilot for the safety function and ex-ternal air diaphragm-actuated pilot for the relief function.The operating history of the SRV has been poor.A new design is used in some plants but the operational history is too brief to evaluate the effectiveness of the new design.Another way of improving the performance of the valves is to reduce the number of challenges to the valves.This may be done by the methods described above or by other means.The feasibility and contraindications of reducing the number of challenges to the valves by the various methods should be studied.These changes, which are shown to decrease the number of challenges without compromising the performance of the valves or other systems, should be implemented.
The failure of an SRV to reclose will be the most probable cause of a small-break LOCA.Based on the above guidance and clarification, results of a detailed evaluation should be submitted to the staff.The licensee shall document the proposed system changes for staff approval before implementation.
Nine Mile Point Unit 2 Position The BWR Owners Group (BWROG).evaluated the NRC-suggested modifications listed earlier.Section 4.3 of the BWROG study (March 31, 1981)states: "For comparing the various valves, the Three-Stage Target Rock Valve was taken as the benchmark valve with an assumed normalized factor of 1.0 for probability to stick open when challenged." Section 4.3.3 compares Crosby and Dikkers SRVs to the three-stage target rock, and states: "Based on valve qualification test data and limited operating experience, a normalized factor of 1.10-89 Nine Mile Point Unit 2 FSAR 0.125 was assigned for their relative probability to stick open, when challenged." Since the Unit 2 design includes Dikkers SRVs, a reduction of challenges, relative to the benchmark valve, of roughly one order of magnitude, is achieved;therefore, the intent of the NUREG is satisifed.
The Unit 2 design does not incorporate any of the proposed changes listed in NUREG-0737, since the BWROG study has determined that either unjustified increases in system complexity and/or minimal reduction (less than 5 percent)in SRV challenge rate would result from these changes.II.K.3.17 REPORT ON OUTAGES OF EMERGENCY CORE-COOLING SYSTEMS LICENSEE REPORT AND PROPOSED TECHNICAL SPECIFICATION CHANGES FSAR Cross Reference Section 6.3, 16.3/4.5 NUREG-0737 Position Several components of the emergency core-cooling (ECC)systems are permitted by technical specifications to have substantial outage times (e.g., 72 hours for one diesel-generator; 14 days for the HPCI system).In addition, there are no cumulative outage time limitations for ECC systems.Licensees should submit a report detailing outage dates and lengths of outages for all ECC systems for the last 5 years of operation.
The report should also include the causes of the outages (i.e., controller failure, spurious isolation).
The present technical specifications contain limits on allowable outage times for ECC systems and components.
However, there are no cumulative outage time limitations on these same systems.It is possible that ECC equipment could meet present technical specification requirements but have a high unavailability because of frequent outages within the allowable technical specifications'he licensees should submit a report detailing outage dates and length of outages for all ECC systems for the last 5 years of operation, including causes of the outages.This report will provide the staff with a quantification of historical unreliability due to test and maintenance outages, which will be used to determine if a need exists for cumulative outage requirements in the technical specifications.
Amendment 23 1.10-90 December 1985 Nine Mile Point Unit 2 FSAR Based on the above guidance and clarification, a detailed report should be submitted.
The report should contain (1)outage dates and duration of outages;(2)cause of the outage;(3)ECC systems or components involved-in the outage;and (4)corrective action taken.Test and maintenance outages should be included in the above listings which are to cover the last 5 years of operation.
The licensee should propose changes to improve the availability of ECC equipment, if needed.Applicant for an operating license shall establish a plan to meet, these requirements.
Nine Mile Point Unit 2 Position NMPC will report ECCS outages via LERs and Annual Summary Reports as required by technical specifications.
Amendment 9 1.10-90a March 1984 Nine Mile*.Point'nit 2 FSAR THIS PAGE INTENTIONALLY BLANK Amendment 9 1.10-90b March 1984 Nine Mile Point Unit 2 FSAR II.K.3.22 RCIC SUCTION SOURCE FSAR Cross Reference Sections 5.4.6, 7.4 NUREG-0737 Position The reactor core isolation cooling (RCIC)system takes suc-tion from the condensate storage, tank with manual switchover to the suppression pool when the condensate storage tank level is low.This switchover should be made automatically.
Until the automatic switchover is implemented, licensees should verify that clear and cogent procedures exist for the manual switchover of the RCIC system suction from the con-densate storage tank to the suppression pool.Nine Mile Point Unit 2 Position The Unit 2 project will implement the NRC.position to automatically transfer RCIC suction source.Condensate storage tank low water inventory will initiate automatic transfer of the suction of the RCIC pump to the suppression pool.1.10-93 Nine Mile Point Unit 2 FSAR II.K.3.24 RCIC AND HPCI SUPPORT POWER FSAR Cross Reference Section 9.4 NUREG-0737 Position Long-term operation ofthe reactor core isolation cooling (RCIC)and high pressure coolant injection (HPCI)systems may require space cooling to maintain the pump room tem-peratures within allowable limits.Licensees should verify the acceptability of the consequences of a complete loss of ac power.The RCIC and HPCI systems should be designed to withstand a complete loss of offsite ac power to their sup-port systems,'ncluding coolers, for at least 2 hr.Nine Mile Point Unit 2 Position The Unit 2 ECCS design employs a cubicle arrangement to en-sure physical, electrical, and environmental, separation of each portion ,of the ECCS.The RCIC system is also located within a separate cubicle.The HPCS pump room is cooled ,by either of two fully redundant Category I unit space coolers.The remaining ECCS pump rooms and the RCIC pump room are each cooled by one Category I unit space cooler with an ad-ditional cooler provided as a spare.These coolers are part of the reactor building heating, ventilation, and air con-ditioning (HVAC)system which utilize cooling water from the service water (SWP)system.The safety-related portions of the SWP system are powered from the standby diesel generators following a loss of offsite power;therefore a reliable supply of cooling water is provided.Likewise, the control systems involved in the operation of the unit coolers also receive their power from the diesel generators following a loss of offsite power.This design assures that the pump room temperatures are maintained within normal limits for an indefinite period following a complete loss of offsite power.1.10-94 Nine Mile Point Unit 2 FSAR II.K.3.27 COMMON WATER LEVEL REFERENCE FSAR Cross Reference Sections 7.3, 16.3/4.3 NUREG-0737 Position Different reference points of the various reactor vessel water level instruments may cause operator confusion.
Therefore, all level instruments should be referenced to the same point.Either the bottom of the vessel or the top of the active fuel is a reasonable reference point (NUREG-0737).
Nine Mile Point Unit 2 Position Unit 2 380.69 point plate.upset, utilizes a common water level reference elevation at in above the vessel invert elevation.
This reference corresponds to the top of the upper core support All f ive level instrumentation ranges (shutdown, wide, narrow, and fuel)utilize this reference.
Amendment 23 1'0-97 December 1985 Nine Mile Point Unit 2 FSAR II.K.3.28 ADS ACCUMULATORS FSAR Cross Reference Sections 5.2, 6.3, 9.3.1 NUREG-0737 Position Safety analysis reports claim that air or nitrogen accumulators for the automatic depressurization system (ADS)valves are provided with sufficient capacity to cycle the valves open five times at design pressure.GE has also stated that the emergency core cooling systems (ECCS)are designed to withstand a hostile environment and still perform their function for 100 days following an accident.The licensee should verify that the accumulators on the ADS valves meet these requirements, even considering normal leakage.If this cannot be demonstrated, the licensee must show that the accumulator design is still acceptable.
The ADS valves, accumulators, and associated equipment and instrumentation must be capable of performing their functions during and following exposure to hostile environments, taking no credit for nonsafety-related equipment or instrumentation.
Additionally, air (or nitrogen)'eakage through valves must be accounted for in order to assure that enough inventory of compressed air is available to cycle the ADS valves.Nine Mile Point Unit 2 Position The primary source of pneumatic supply and leakage makeup for the ADS accumulators will be from two nitrogen storage tanks located outside the reactor building.Long-term post-accident supply and leakage makeup will be provided by two bottled nitrogen connections, also located outside the reactor building.Two Category I nitrogen accumulator tanks are located in the reactor building and are pressurized from the nitrogen storage tanks.These two large accumulators provide pneumatic supply and leakage makeup for the seven smaller ADS accumulators located inside the primary containment.
This arrangement provides sufficient time to place the bottled nitrogen system into service if the plant condition requires long-term ADS operation.
The ADS valves, including pilot operators, are designed to withstand a hostile environment and still perform their safety function for 100 days following an accident.Amendment 23 1.10-98 December 1985 Nine Nile Point Unit 2 FSAR TABLE III D 3 4-1 RESULTS OF TOXIC CHENICAL ANALYSIS FOR THE CONTROL ROON HABITABILITY STUDY Chemical Location J.A.FitzPatrick Plant Alcan Route 104 Nine Nile Point Unit 1 Nine Nile Point Unit 2 Copper Neld Bimetallics Group Chemical Nm HgSOg COm Propane Clm Propane Nm HCl COm Hcl Nm COm Ng COg Hm SOg HgSOg COg Halon 1301 Nm Isopropyl Alcohol 1 Naximum Control Room Concentration

Nine Mile Point Unit 2 FSAR In addition to the load combination requirement for the con-tainment design, there is a fatigue analysis requirement for the liner of a concrete containment.
For'steel containment, the consideration of fatigue is specified in ASME Boiler and Pressure Vessel Code Section III, Division 1, Subsection NE.However, the liner on the concrete foundation mat of the steel containment should be treated as the liner of a con-crete containment.
Since the staff's position requires the pool liner to be designed in accordance with the ASME BEcPV Code Section III, Division 1, Subsection NE, it is suggested that a generic method to consider fatigue of both the steel containment and the steel liner in the concrete containment should be adopted.Position The absolute sum method of combining dynamic loads is used for the design of structures.
The details of load com-binations used in designing the structures are covered in FSAR Section 3.8.The Unit 2 primary containment liner is evaluated for fatigue to the requirements of ASME Boiler and Pressure Ves-.sel Code Section III, Division 1, Subsection NE.LICENSING ISSUE: 43-FIUID/STRUCTURE INTERACTION I I s sue.The dynamic forcing functions for various loads have been established through testing on models that.are generally more stiff than the actual structures to which the lo'ads will be applied.By directly applying such forcing func-tions'o actual structures in the analysis, the interactive effect between the fluid mass and the structure is neglected..
Under certain conditions, this effect may be significant".
It is proposed that a generic approach to study;such effects should be established.
Position This issue is not directly applicable to the Unit 2 Mark II containment.
Since the Unit 2 containment is stiff in the suppression pool region and the dynamic forcing functi'ons are conservatively defined, any interactive effect between the fluid: mass and the structure is inherently included.Amendment 3 1.12-31 June 1983 Nine Mi'le Point Unit 2 FSAR LICENSING ISSUE 44-.LONG-TERM POST-LOCA OPERABILITY OF DEEP-DRAFT ECCS PUMPS Issue IE Bulletin 79-15, dated July 1979, identified problems with deep-draft ECCS pumps that could threaten their long-term post-LOCA operability.
Structure flexibility; shaft/column misalignment; vibrational frequencies near rotation speeds;inlet flow induced vortices;and dimensional deficiencies such as those discovered with certain LaSalle ECCS pumps, could cause excessive vibration and bearing wear.The'RC staff has asked applicants to define programs and provide data that compare the expected servic'e life with the ac-cumulated operating time and confirm the long-term operability.
Position The inherent design features of the Byron Jackson ECCS pumps in Unit 2.preclude excessive vibration and bearing wear.Each pump is supplied with a casing or suction barrel and is not installed in a wet sump.They do not have long, limber columns;the longest pump is only 24 ft, compared to the 30-to 60-ft pumps described in IE Bulletin 79-15.Also the pump assembly rigidity is enhanced by seismic rings between the assembly and the barrel.The pumps use a double-suction first stage to provide stability over a wide range of flows.Column frequencies are well removed from pump speed.Larger diameter barrels provide low flow velocities around pump inlets, and ring seismic restraints act" as flow straighteners to suppress vortex formation.
The pumps'have high-precision, keyed, sleeve-type couplings.
Long-term operability is assured by preventive maintenance, functional testing and surveillance, and vibration monitoring.
Scheduled preventive maintenance consists of resistance readings of motor windings;lubrication of critical rotating components; general cleaning and inspec-tion of rotating electrical equipment; and inspection, overhaul, alignment, and adjustment of impeller lift.Functional-testing measurements of pump inlet pressure, differential pressure, flow rate, vibration, and upper temperature, as prescribed by Section XI of the ASME BEcPV Code, provide data for engineering analysis to identify per-formance changes or trends.In addition, vibration data bases, established during the preoperational/startup testing, are compared with functional-testing vibration data to monitor journal bearing wear and shaft whip."Amendment 4 1.12-32 September 1983 Nine Mile Point Unit 2 FSAR ISSUE: A-24-ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED EIECTRICAL EQUIPMENT~NRC Descri tion Accidents postulated for nuclear power plants could create severe environmental conditions such as temperature, pressure, humidity, radiation, chemical sprays, and submergence both inside and, outside the containment.
In order to ensure that the electrical equipment in safety systems will perform their intended function, it is required that such equipment be qualified to perform in the environment associated with an accident.Schedule for NRC Resolution NUREG-0588, Revision 1, completed August 1981.IEEE-323 and Regulatory Guide 1.89 contain specific guidance for meeting the requirements.
The final rule concerning environmental qualification was published in the Federal Register on January 21, 1983.Unit 2 Position Environmental qualification of Class lE equipment located in harsh environments meets or exceeds the requirements for Category II qualification in accordance with NUREG-0588, including the guidance provided for incorporation of IEEE-323.The mild environments qualification program has not been addressed to the NRC.Amendment 9 1.13-11 March 1984 Nine Mile Point Unit 2 FSAR ISSUE: A-26-REACTOR VESSEj PRESSURE TRANSIENT PROTECTION g)NRC Descri tion Pressure transients in PWRs which have exceeded the pressure/temperature limits of the reactor vessel have occurred (usually during plant startup or shutdown, when the temperature of the reactor coolant was low).The transients have been attributed to personnel error, procedural deficiencies, component random failure, and spurious valve actuation.
Schedule for NRC Resolution NUREG-0224 completed September 1978.All operating PWRs have an installed system to protect against low temperature overpressurization.
However, systems in 10 plants have not been completely reviewed against acceptance criteria.Unit 2 Position As Unit 2 is a BWR, this issue is not applicable.

There are no residential, agricultural, or in-dustrial developments on the site other than Nine Mile Point Unit 1 and the James A.FitzPatrick plant, which are both operating nuclear power plants.The site area is posted as private property, and access to the station buildings is controlled.
2.1~1~2 Site Area Map Main plant structures and the cooling tower occupy ap-proximately 9.3 ha (22.9 acres)of the total site area of 364 ha (900 acres).Figures 2.1-2 and 2.1-3 show the Unit 2 site plan including property and exclusion area boundaries, principal structures Amendment 26 2.1-1 May 1986 Nine Nile Point Unit 2 FSAR for Units 1 and 2, ground contours, railroads, highways, and transmission lines in the site area.2.1.1.3 Boundaries for Establishing Effluent Release Limits The.minimum distance from Unit 2 to the EAB is approximately 1.4 km (0.87 mi)to the southwest.
Exclusion area distances for the site are shown on Figure 2.1-2.The restricted area for the station follows the same boun-dary as the exclusion area.Lake Road provides access from Lakeview Road and County Road 29 to Nine Nile Point Units 1 and 2 and to the FitzPatrick plant.Access to the Visitors Center at, Nine Mile Point is also from Lake Road.Although Lake Road is privately owned between Lakeview Road and County Road 29, public use is permitted during normal operating conditions.
Niner Road provides an alternate route between Lakeview Road and County'oad 29.This road is in the town of Scriba.No public use restrictions affect public use along Niner Road.There are no state or other roads, shipping lanes, or rail lines crossing the restricted area.The Oswego River is located approximately 8.8 km (5.5 mi)west of the restricted area boundary at its closest point.North of the plant, the restricted area boundary follows the shoreline of Lake Ontario.A fence along the shoreline prevents unauthorized access to Unit 2.Local authorities will notify persons on the lake in the vicinity of the plant of the need to leave the area in the event of an emergency.
The boundary of the restricted area is posted with signs to assure public awareness of access restrictions.
During emergency conditions, public access to the restricted area, including the Visitors Center, will not be permitted.
The necessary authorities will be contacted to enforce access restrictions from local roads (Section 13.3).The radiation dose outside the restricted area will be within the guidelines of 10CFR20, 10CFR50, Appendix E (Appendix 11B), and 40CFR190.10.
Dose estimates for persons within the rest:-icted area are presented in Section 12.4.There are two gaseous release points for routine airborne radioactive emissions:
the com-bined radwaste/reactor building vent and the stack.Rad-waste and reactor vents are combined on the reactor building to form one release point (Figure 11.3-2).Distances from the stack and from the vent to the restricted area boundary are shown in Table 2.1-1 as a function of direction.
Amendment 3 2.1-2 June 1983 Nine Mile Point Unit 2 FSAR 2.1.2 Exclusion Area Authority and Control 2.1.2.1 Authority Distances from the plant (EAB)are measured from the approximately 1.6 km (1 mi)the southwest, and over 2.1 boundary.Exclusion area on Figure 2.1-2.to the exclusion area boundary centerline of the reactor and to the east, 1.4 km (0.87 mi)to km (1.3 mi)to the southern site distances for the site are shown NMPC is owner in fee of the property within the exclusion area except for that portion encompassed by the James A.FitzPatrick site owned by NYPA.The authority which permits NMPC to control activities over that portion of the Unit 2 EAB owned by NYPA is a formal agreement between NMPC and NYPA executed on March 9, 1970, which provides for reciprocal inclusion of each party's project property in the exclusion area for Nine Mile Point Units 1 and 2 and The James A.FitzPatrick Nuclear Power Plant.No one resides in the exclusion area and no easements have been granted within the EAB, except such agreements between NMPC and NYPA for joint use of facilities and access to them for that purpose.The Emergency Plan (Section 13.3)discusses the means of" control of this area in the event of an accident.A private, hard-surfaced, east-west road crosses the site connecting with Oswego County Highway Route 29.A spur of the Consolidated Railroad Corporation provides rail service to the station.Since the site is located on a navigable portion of Lake Ontario, the station is accessible by barge for construction and supply purposes.2.1.2.2 Control of Activities Unrelated to Plant Operation The Energy Information Center is owned by NMPC and NYPA and is located on the site west of Nine Mile Point Unit 1.The center has averaged more than 50,000 visitors annually since its official opening in 1967.The center provides visitor facilities including educational exhibits, picnic and playground areas, and nature study trails.Control of recreational activities in the vicinity of the plant is discussed in the Emergency Plan (Section 13.3).As discussed in Section 13.3, a study for evacuation of area population surrounding the plant was performed.
Calculated doses received by any individual in this area in the event of an accident are within allowable limits (Chapter 15).Plant tours normally are not provided due to security and insurance restrictions.
Amendment 19 2.1-3 May 1985 Nine Mile Point Unit 2 FSAR 2.1.2.3 Arrangements for Traffic Control The exclusion area is traversed by one road and a rail spur (Section 2.1.2.1).Under emergency conditions, the appropriate authority (Section 13.3)is contacted in the event, that it becomes necessary to control traffic on Lake Road.When reguested, the Consolidated Railroad Corporation controls railroad-traffic through the exclusion area.Amendment 4 2.1-3a September 1983 Nine Nile Point Unit 2 FSAR THIS PAGE INTENTIONALLY BLANK Amendment 4 2.1-3b September 1983 Nine Mile Point Unit 2 FSAR 2.1~2.4 Abandonment, or Relocation of Roads No public roads within the exclusion area have been aban-doned or relocated.
2'~3 Population Distribution 2.1.3.1 Population Within 16 km (10 mi)In 1980, Oswego County had an estimated population of 113,901-at an average density of 43 people/sq km (111 people/sq mi)'~This population density is con-siderably lower than the state average of 137 people/sq km (356 people/sq mi).The 1980 population and population den-sity for the eight towns and one city within 16 km (10 mi)of Unit 2 are listed in Table 2.1-2.The total 1980 population within 16 km (10 mi)of Unit 2 is estimated to be 35,467.This population is projected to in-crease to approximately 74,082 by the year 2030'~'.The 16-km (10 mi)area contains all or portions of one city and eight towns: the city of Oswego, and the towns of Minetto, Scriba, New Haven, Oswego, Mexico, Palermo, Volney, and Richland.City and town boundaries are shown on Figure 2.1-4.Of the eight towns and one city in the 16-km (10 mi)area, the city of Oswego is the largest in population, containing approximately 19,793 people in 1980.Following the city of Oswego in population size are Granby, Scriba, and Volney with estimated 1980 populations of 6,341, 5,455, and 5,358, respectively'~'.
Population and the 1970-1980 percent change in population for the towns and city within the 16-km (10 mi)area are listed in Table 2.1-3.It is expected that a large portion of the population growth in the 16-km (10 mi)area will occur around the southeastern fringes of the city of Oswego, with the surrounding towns absorbing much of the city's satellite growth'opulation distribution within 6 km (3'mi)of the station is based on the results of a field survey conducted in May 1982.Population distribution between 6 (3.7 mi)and 16 km (10 mi)is based on a house count from U.S.Geological Survey maps, photorevised in 1978, on which Amendment 26 2'-4 May 1986 Nine Mile Point Unit-2'FSAR 2.1.3.4 Low Population Zone The low population zone (LPZ)surrounding Unit 2"encompasses an area within a 6;4 km (4 mi)radius from the Nine Mile Point Unit 1 stack.LPZ boundary accident doses for Unit 2 are calculated at a distance of approximately'.1 km (3.8 mi)from the Unit 2 stack, which is 6.4 km, adjusted for the distance between the Unit 1 and Unit 2 stacks.Figure 2.1-19 depicts the LPZ.The distance for the LPZ was chosen based on the requirements of 10CFR100.11.The LPZ is expected to contain approximately 2,315 people in the year 1985 at an average density of 48 people/sq km (125 people/sq mi).By the year 2030, the: LPZ"population is expected to have increased to approximately.
4;372 at" a'n average density of 91 people/sq km (236 people/sq mi).The only facility in the LPZ that attracts a transient population is the Ontario Bible Campground at Lakeview, located approximately 1.5 km (1.0 mi)west-southwest of the station.This campground is a privately-owned facility operated on a 52-acre lakeshore plot.Groups of up to 500 persons use this camp during the summer and as many as 1,500 people may gather there for short periods on Sundays throughout the summer.The facility is unused during the balance of the year except for an occasional weekend in the spring and fall.2.1.3.5 Population Centers In 1980, the closest population center, as defined by 10CFR100, to Unit 2 was the city of Syracuse, which con-tained approximately 170, 105 people.The city'closest corporate boundary to Unit 2 is approximately 53 km (33 mi)south-southeast:.
The city of Syracuse is part of the Syracuse SMSA, which encompasses Onondaga, Oswego, and Madison Counties.Based on county-level population projections provided by the New York Department of Commerce, the population of the city of Oswego will exceed 25,000 people and become the nearest population center in the year 2000'4'.This estimate may prove to be somewhat high based on historical growth in the city;however, the estimate is useful because it provides a conservative estimate f or use in calculating doses f rom potential accidents.
Amendment 25 2.1-7 March 1986 Nine Mile Point Unit 2 FSAR Although Oswego City's closest political boundary is ap-*proximately 7.24 km (4.5 mi)from the site, no conflict'xists with the LPZ/population center distance requirements defined in 10CFR100 since the boundary of the city'residential area is located approximately 8.85 km (5.5 mi)away, over 1.33 times the distance of the LPZ.Future residential growth is not anticipated to decrease this distance since the area between the residential and political boundaries.
is'sed and zoned for industry.It is most likely that residential growth will occur to the south and southeast where land is available and more desirable from a residential perspective, rather than into an area of strong industrial character.
A zoning map for the city is provided on Figure 2.1-20 which shows the difference between the industrial and residential boundaries closest to the site.Amendment ll 2%1 7a June 1984 I I I I CONTROLLED SY tHE COASTOVARDDVRINO EMEROENCIES IN ACCORDANCE WITHLETTER DFAOREEMENT

====9.3.1 Compressed====
Air Systems The compressed air systems consist of the instrument air system (IAS), the service air system (SAS), and the breathing air system (AAS).All three compressed air systems are used only for nonsafety-related equipment and components during normal plant operation.
The instrument air system is described in Section 9.3.1.1, followed by descriptions of the service air system and the breathing air system in Sections 9.3.1.2 and 9.3'.3, respectively.
All instrumentation and control systems located inside the reactor primary containment, including the safety-related equipment and components of the automatic depressurization system (ADS)and the four inboard main steam isolation valve (MSIV)actuator accumulators are independently supplied with nitrogen gas from the instrument nitrogen system (GSN).The automatic depressurization system and the instrument nitrogen systems are described in'ections 9.3.1.4 and 9.3.1.5, respectively.
28 The four outboard main steam isolation valve (MSIV)actuator accumulators are supplied with air from the reactor building instrument air receiving tank.28 9.3.1.1 Instrument Air System 9.3.1.1.1 Design Bases Safet Desi n Basis The instrument air system is not a safety-related control air system.It is not required to effect or support the safe shutdown of the reactor or to perform any safety-related functions associated with its operation.
However, all instrument air system piping, valves, and fittings located in Category I areas are seismically analyzed and supported in accordance with safe shutdown earthquake (SSE)design requirements so that their failure will not damage safety-related equipment, piping, and components.
The instrument air system component design bases are given in Section 3.2.Amendment 28 May 1987 Nine Mile Point Unit 2 FSAR Power Generation Bases The instrument-air system is designed to supply clean, dry, and oilfree air at 80 to 100 psig to all nonsafety-related
'plant instrumentation and control systems.However, all instrumentation and control systems located inside the Amendment 28 9.3-la May 1987 Nine Mile Point Unit 2 FSAR Each two-stage instrument air compressor assembly includes an intercooler, aftercooler, and air receiver tank.The instrument air compressor cylinders are of the non-lubricated type.The intake air filters and silencers are located on the turbine building roof.Cooling water is supplied to the air compressor cooling water system and heat exchangers from the reactor building closed-loop cooling water system.Two refrigerant-type air dryers, with two prefilters and two afterfilters, are provided on the instrument air system supply header to filter and dry the air to a dewpoint of 35 F at 125 psig.The instrument air system distribution piping network is supplied from a separate instrument air receiver tank located downstream of the refrigerant dryers and air filters.Instrument air used only for nonsafety-related instrumentation and control systems is distributed throughout the plant from this air receiver tank.The service air system supply header is branched off the common compressed air supply header upstream of the instrument air dryers and filters.An isolation block valve on the service air system main supply branch header will automatically close and shut off the service air supply when the common compressed air supply header pressure decreases to less than 85 psig.The automatic shutoff and isolation of the service air system is designed to prevent decreased compressed air supply header pressure, as during high service air demand flows, which may adversely affect the operability of the instrument air system.Each instrument air compressor has automatic unloader controls and a remote manual/automatic selector station for automatic start-stop operation.
In the selected lead position the compressor runs continuously after starting and automatically unloads to maintain its air receiver pressure.In the lag position the compressor will automatically start when the common air supply header pressure drops below the low-pressure setpoint of 90 psig.In the backup mode, the compressor will automatically start when the common air supply header pressure decays below the low-low pressure setpoint of 85 psig.The air compressors are operated from the normal plant power supply.Cooling water to the air compressor cooling system heat exchangers is supplied by the reactor=building closed loop cooling system (Section 9.2.2.1).Amendment 27 9.3-3 July 1986 Nine Mile Point Unit 2 FSAR 9.3.1.1.3 Safety Evaluation The three instrument air compressors, i.e., the lead, lag, and backup units, operate to maintain the required pressure at the air receivers which provide the station's instrument air system with an air supply pressure of 100 to 120 psig.Actuation of the selected lag unit is automatic when the compressed air supply header pressure decreases below 100 psig, and the selected backup unit automatically starts when the header pressure further decays below 85 psig.The instrument air compressors and air receivers have sufficient capacities to supply the requirements of plant instrumentation and control systems.The loss of instrument and control air causes air-operated valves to fail to appropriate safe positions.
9.3.1.1.4 Inspection and Testing Requirements The instrument air system operates on a continuous basis.It is maintained and monitored, and abnormal conditions are alarmed during normal plant operation.
The instrument air system will be tested in accordance with the applicable requirements of Regulatory Guide 1.68.Preoperational testing of the instrument air system is addressed in Table 14.2-43.9.3.1.1.5 Instrumentation Requirements Manual and automatic controls are provided for maintaining an adequate supply of instrument air for air-operated instruments, equipment, and components.
The controls and monitors described below are located in the main control room.The control system logic is shown on Figure 9.3-2.Each instrument air compressor control system has a three-step regulator for free air unloading at constant speed and dual controls for both manual and fully automatic start-stop operation.
The three-step regulation allows the compressor to operate at full, one-half, and zero load at rated speed as a function of the system air receiver pressure.The solenoid-operated three-way unloader valve in the control system automatically provides a 15-sec time delay for free Amendment 26 9.3-4 May 1986 Nine Mile Point Unit 2 FSAR increasing the piping internal pressures.
Therefore, piping inside the primary, containment is protected b'y thermal relief valves.The piping outside the primary containment is protected by the air compressor and receiver relief valves.Piping in Category I areas has been designed so that, its failure will prevent damage to safety-related equipment.
With the exception of the containment penetrations and isolation valves, the service air system is nonsafety-related.
9.3.1.2.4 Inspection and Testing Requirements No special inspection and testing are required following preoperational testing except for ISI of the containment, penetrations (Section 6.6).9.3.1.2.5 Instrumentation Requirements The air supply for the service air system is provided by the-instrument air system.The only controls and monitors for the service air system are an instrument air/service air operated block (globe)valve and its associated alarm which is located.in the main control room.The control logic is shown on Figure 9.3-'2.In the normal mode, the service air system block valve can be opened locally at LCS738 only if a low-low pressure condition does not exist.The valve will close automatically on low-low pressure.The valve can be opened and closed manually.27 Monitorin An alarm is provided for service air system block valve closure.9.3.1.3 Breathing Air System The breathing air system provides clean, dry, oilfree air to various areas throughout the plant for breathing.
9.3.1.3.1 Design Bases Safet Desi n Bases The breathing.air system is not required to effect or support safe shutdown of the reactor ot to perform in the Amendment 27 9.3-7 July 1986 Nine Mile Point Unit 2 FSAR operation of reactor safety features.However, all items contained in Category I areas are seismically analyzed and supported for SSE conditions so that their failure will not damage safety-related equipment.
For containment penetrations, see Section 3.2.0 erational Desi n Basis The breathing air system has been designed to provide air suitable for breathing at selected breathing air stations for use by unit personnel during potential or actual airborne contamination situations.
9.3.1.3.2 System Description Compressed air is supplied to the breathing air syst: em by an oilfree reciprocative air'ompressor (Figure 9..3-3).The compressor is designed with a capacity of 250 scfm at 85 psig discharge pressure and is equipped with an inlet filter and aftercooler.
Inlet air to the compressor"is taken from outside the turbine building, compressed, cooled, and discharged via headers to two air receivers.
The compressor is provided with manual and automatic starting and shutdown features.Cooling is provided by a self-contained cooling unit that consists of a circulating pump and forced draft type radiator.Air quality is maintained by an inline three-stage filtration unit that removes oil, water, particulates, and carbon monoxide, and delivers clean air that meets OSHA requirements for breathing air.During normal unit power operation, breathing'air piping within the primary containment will be physically disconnected by a flexible hose connection and isolated by valves inside and outside the containment.
The compressor aftercooler is a shell and tube, counterflow heat exchanger with air passing through the tubes and coolant circulating around the tubes.An integral moisture separator equipped with an automatic drain trap'emoves condensed moisture from the cooled air.Coolant is provided by a self-contained cooling system.The aftercooler is built to ASME Section VIII, Division 1, requirements for a design pressure of 125 psig, and is equipped with a relief valve.Amendment 23 9.3-8 December 1985 Nine Mile Point Unit 2 FSAR The automatic depressurization system is safety-related, and'all pressure-retaining components of the system are designed, constructed, and inspected in accordance with the applicable requirements.of ASME Section III, Division 1, Subsection ND for Class'3 components, and Subsection NC for Class 2 components.
Not included in this safety-related classification are the nitrogen gas storage tanks, equipment, and components located in the yard outside-the reactor building.Piping segments that.penetrate the primary containment and serve as a containment boundary are designed to Safety Class 2, Category I requirements.
The loss of nitrogen gas-fo'r instrumentation and controls causes gas-operated valves to fail to appropriate safe positions.
In the event that the nitrogen gas supply from the nitrogen gas storage tanks is lost, a 5-day supply is available to the accumulators from ADS nitrogen receiver tanks 2IAS*TK4(Z-)
and 2IAS*TK5(Z-).
In addition, there are provisions for recharging the ADS nitrogen receiver tanks through its individual supply lines located in a missile-protected area outside the standby gas treatment building from special emergency tube trailer supply connections.
These special, emergency recharging lines are part of the GSN system and are classified Seismic Category I, Safety'lass 3.Power Generation Bases The automatic depressurization system requires clean, dry, oilfree nitrogen gas at approximately 175 psig to be supplied to the selected group of seven main steam safety relief valves and their respective accumulators located inside the reactor primary containment.
This designated group of ADS safety relief valves and accumulators is divided into two subgroups with three or four valves and accumulators in each subgroup.Each subgroup is supplied with nitrogen gas from one of two separate ADS receiver tanks.Each ADS receiver tank is supplied with nitrogen gas at 365 psig from a bank of six horizontal, high-pressure nitrogen gas storage tanks located outside the reactor building.Nitrogen gas supplied for instrumentation and controls meets or exceeds the equivalent air quality requirements established for safety-related control air systems (SRCAS)by ANSI MC11.1-1975 (approved-January 15, 1976)(ISA-S7;3), Quality Standard for Instrument Air.All piping, valves, and fittings associated with the automatic depressurization system are of stainless steel materials.
Also, the system will be given a complete Amendment 28 9.3-11 May 1987 I Nine Mile Point Unit 2 FSAR preoperational cleaning., until the applicable acceptance cleanliness levels"are: established and verified.In.addition, since the piping system materials are corrosion-resistant, the cleanliness levels achieved during preoperational cleaning are expected to be maintained and controlled to within acceptable limits.Each of the six high-pressure nitrogen gas storage vessels is designed, fabricated, tested, and stamped in accordance with the ASME Unfired Pressure Vessel Code, Section VIII, and conforms to Code Case No.1205 for seamless integrally forged vessels.The six-vessel modular assembly is provided with manifold isolation valves which separate three active vessels and three reserve vessels.A fill stanchion is provided for refueling from a high-pressure tube trailer.9.3.1.4.2 System Description The automatic depressurization system is supplied with nitrogen gas from a bank of six horizontal, high-pressure nitrogen gas storage tanks located outside the reactor building.Nitrogen gas is supplied to two ADS nitrogen receiver tanks at 365 psig.Each ADS nitrogen receiver tank supplies nitrogen gas to its corresponding subgroup of either three or four ADS valves and accumulators through a 365/185 psig pressure reducing station.These two ADS nitrogen receiver tanks provide makeup nitrogen to compensate for valve leakage losses and to maintain ,the required pressure at the accumulators.
A diaphragm-type'DS air compressor is provided to supply instrument quality air fortesting purposes, if desired, during plant shutdown and maintenance periods.Its discharge air supply connection is valved off during normal plant operation.
9.3.1.4.3 Safety Evaluation The two ADS nitrogen receiver tanks supplied by the bank of six horizontal nitrogen gas storage tanks will operate to maintain the required ADS valve-accumulator pressure of 175 psig.Each nitrogen gas accumulator provides a passive safeguard which automatically supplies a motive source for the operation of each, SRV in the automatic depressurization system.The failure of a pilot control valve in the valve actuators can only affect a single SRV.This is due to the independence of the other, and a postulated single failure does not prevent the operation of the remaining units.The Amendment.

Amendment 24 9.3-11d February 1986 Nine Mile Point Unit 2 FSAR 9.3.1.5 Instrument Nitrogen System 9.3.1.5.1 Design Bases Safet Desi n Basis Instrumentation and control systems located inside the reactor primary containment are supplied with nitrogen gas at 120 psig from the instrument nitrogen system (GSN).The IAS designation is retained for these systems which are nitrogen gas exclusively during normal plant operation.
Instrumentation and control systems located inside the reactor primary containment, except as described in Section 9.3.1.4.5, are not safety related.However, all piping, valves, and fittings located in Category I areas are seismically analyzed and supported in accordance with safe shutdown earthquake (SSE)design requirements so that their failure.will not damage safety-related equipment.
For containment penetrations and items within the containment areas, see Section 3.2.Power Generation Desi n Bases Nitrogen gas for instrumentation and control systems located inside the reactor primary containment areas is supplied from the vapor spaces of two 11,000-gal liquid nitrogen vertical storage tanks maintained under a constant pressure of approximately 200 psig.The liquid nitrogen tanks are located in the yard area, north-northeast of the reactor building, alongside the railroad access lock.From the liquid nitrogen tanks nitrogen flows through an active bank of finned ambient vaporizers, a trim heater for heating to 70 F, and a 200/120 psig pressure-reducing station.An instrument nitrogen receiver is provided inside the reactor building for additional storage capacity.Nitrogen gas for instrumentation and controls inside the primary containment, is distributed from this nitrogen receiver.A nitrogen gas backup supply connection is provided from the high-pressure nitrogen gas storage cylinders to the 26 (instrument nitrogen receiver through a 365/100 psig pressure-reducing station.Although instrumentation and control systems within the reactor primary containment are nonsafety-related, the nitrogen gas supplied for these systems meets or exceeds the quality requirements of ANSI MC11.1-1975 (approved January 15, 1976)(ISA-S7.3), Quality Stan-dard Instrument Air, for use with safety-related Amendment 26 9.3-lie May 1986 Nine Mile Point Unit 2 FSAR control,air systems (SRCAS).Additionally, these piping systems will receive a preoperational cleaning for the removal of contaminants and to.provide the required cleanliness level required.Also, all piping associated with these systems is of stainless steel, which eliminates the potential for particulate contamination coming from the piping material.The pressure-retaining components of the instrumentation and control systems located inside the reactor primary containment are designed, constructed, and inspected in accordance with the applicable requirements of ASME Section III, Division 1, Subsection ND for Class 3 components, and Subsection NC for Class 2 components.
Piping segments that penetrate the primary containment, boundary are designed to Safety Class 2, seismic Category I requirements.
Each 11',000-gal liquid nitrogen storage tank contains the equivalent gas capacity of 1,024,000 SCF of nitrogen.Each storage vessel consists of a Type 304 stainless steel inner tank fabricated to Section VIII of the ASME Code requirements, an outer-carbon steel jacket, and an annular space under vacuum filled with superinsulation for maintaining a low normal evaporation rate of approximately 0.15 percent per day.The normal operating pressure of the liquid nitrogen storage tank is 200 psig.9.3.1.5.2 System Description The nitrogen gas supply for instrumentation and controls" within the reactor primary containment areas is provided by the two 11,000-gal liquid nitrogen vertical storage tanks.located in the yard area (see Figure 9.3-20 for system PEcIDs).These two liquid nitrogen storage tanks also supply nitrogen gas for inerting the primary containment when required.Additionally, a low-pressure slipstream from the nitrogen gas system maintains the reactor primary containment atmosphere inerted during normal plant operations.
A nitrogen gas backup connection to the instrument nitrogen system is provided from the high pressure nitrogen gas'storage cylinders through a 365/100 psig pressure-reducing station during off-normal conditions for instrument nitrogen supply.23 The nitrogen gas supply for instrumentation and controls is normally drawn off the vapor spaces of the liquid nitrogen storage tanks, absorbs heat energy from the surrounding environment, across an active bank of finned ambient vaporizers, heated to 70OF through one of two electric trim heaters, and its pressure reduced from 200 psig to 120 psig.Amendment 23 9.3-11f December 1985 Nine Mile Point Unit 2 FSAR I The instrument nitrogen system is provided with all necessary pressure and temperature indicators, alarms, and safety relief devices for safe and reliable operation.
A solenoid-operated temperature control valve installed in the main supply header is set to close if the nitrogen gas temperature drops to the low temperature setpoint.This is a safeguard feature that prevents the flow of low temperature nitrogen gas into the piping distribution system in the event of a trim heater failure.An instrument nitrogen receiver is provided inside the reactor building for additional storage capacity.Nitrogen gas is distributed throughout the instrumentation and control systems piping network within the reactor primary containment areas from this receiver.9.3.1.5.3 Safety Evaluation The station nitrogen systems operate to supply the instrumentation and'"control systems inside the reactor primary containment with instrument quality nitrogen gas at 120 psig.The liquid nitrogen storage tanks and nitrogen gas.cylinders, nitrogen gas accumulators have sufficient capacities requirements of the instrumentation and within the reactor primary containment.
the six modular receivers, and to supply the control systems 28 The principal gas-operated valves supplied with instrument nitrogen gas inside the primary containment areas are the inboard main steam isolation valves, the main steam safety relief valves, and the drywell vacuum breakers.The selected main steam'safety relief valves in the automatic depressurization system (ADS)are independently supplied with nitrogen gas from the high pressure nitrogen gas storage cylinders described in the previous section, Section 9.3.1.4.Each accumulator in the instrument nitrogen system provides a passive safeguard which automatically supplies a motive power source for the operation of each safety relief valve.The failure of a pilot control valve in the valve actuators is limited to that particular single safety relief valve, as each SRV is independent of the others;and a postulated single failure does not interfere with the operation of the remaining units.The design bases covering the total number of safety relief valves include additional allowances for the malfunction of any one valve.Amendment 28 9.3-1lg May 1987 Nine Mile Point, Unit 2 FSAR The failure modes and effects analysis (FMEA)of the instrument nitrogen systems, as part of the overall instrument air systems, is provided in the Nine Mile Point Unit 2 FSAR FMEA Report.To prevent introducing cold (less than 40 F)nitrogen into the primary containment, the nitrogen temperature, for normal inerting, is controlled ,to 70OF and monitored upstream of the normal vent and purge lines.Low nitrogen temperature (55 F)is alarmed in the control room.Should the temperature continue to fall to 40~F at the outlet of the vaporizer, an independent temperature device will trip the outlet control valve closed.The nitrogen supply to the instrument nitrogen'ystem is fed from nitrogen storage bottles and the ambient vaporizer is followed by trim heaters to hold the temperature at 70 F.The supply is fed to an accumulator prior to any containment penetration, thus essentially
'recluding any cold nitrogen from entering the containment.
In addition, a temperature sensing device just downstream of the trim heater will trip the downstream valve closed.if the temperature drops below 40OF.In addition, there is no equipment or piping in the direct path of the injected nitrogen in either the drywell or wetwell, and the nitrogen system is normally isolated from the primary containment.
Inerting is controlled administratively, and the valves are returned to a closed position after inerting.'I 9.3.1.5.4 Inspection and Testing Requirements The instrument nitrogen system is operated on a continuous basis.It is maintained and monitored, with off-normal conditions alarmed during normal plant operation.
The instrumentation and control systems within the reactor primary containment will be tested in accordance with the requirements of the applicable regulatory positions of Regulatory Guide 1.68.3, as discussed in Table 1.8-1.9.3.1.5.5 Instrumentation Requirements)ze Instrumentation and controls are provided for the manual and automatic operation of the nitrogen instrument systems within the reactor primary containment areas.These controls and monitors are described below.The nitrogen gas system is placed in operation manually, including the trim heaters.In normal operation only one of Amendment, 26 9.3-11h May 1986 Nine Mile Point Unit 2 FSAR two trim heaters is used to'ontrol the nitrogen gas temperature.
The other trim heater is held on standby.The instrument nitrogen systems primary containment isolation valves close when any of the following conditions exist:: the control switch is in the normal closed position, a LOCA isolation signal is present, and the manual isolation switch is activated.
The isolation valves can be manually open'ed when a LOCA isolation signal is not present and the manual isolation switch is not activated.

Amendment 18 9.3-11i March 1985 Nine Mile Point Unit 2 FSAR High temperature samples (steam samples or liquid samples at temperatures greater than 180'F)are condens'ed and/or subcooled using local (close to the sample source)coolers.These coolers are Type 316 stainless steel and are rated at 5,000 psig at 1,000 F.Their maximum working conditions exceed the design conditions of all sample sources.All samples entering the sample panels are cooled sufficiently to ensure operator safety.Each sample line has an air-operated isolation valve (AOV)close to the sample source.These AOVs are manually activated by pneumatic valves from the sample panel.In the reactor and turbine sample systems, the high temperature samples have temperature switches that will automatically close the AOV if the sample temperature in the panel exceeds 180 F.In the radwaste sample system, flow switches are installed on the outlet cooling water lines for the sample coolers.The flow switches will close the sample line isolation AOVs if low cooling water flow is sensed.All AOVs fail closed upon loss of control power or air supply pressure.Manually operated, rod-in-tube pressure-reducing valves reduce any residual high sample pressure in the sample panel.Manual needle or globe valves regulate final grab sample flow.To ensure proper temperature compensation of conductivity measurements, conductivity samples are conditioned to 77+1'F by a constant temperature bath prior to inline analysis.Suitable panel instrumentation is provided to allow proper sample system operation and to ensure the safety of the operator.Grab sample sinks have ventilated fume hoods to collect any airborne contamination.
All sample panels are located in low radiation areas to reduce operator exposure.All liquid sample drainage is directed to the respective building equipment drain system or is collected and returned to the plant.(a3 To provide representative samples, all sample lines are sized to maintain Reynolds numbers in excess of 4,000 (fully turbulent flow).Sample tubing runs are as short as possible and are sized to allow the highest practicable velocities.
All tubing enters the top of the sample panel, thereby allowing the final leg of tubing to be downward in direction.
To minimize coolant loss in case of a leak, tubing with an internal diameter of 0.18 in (reactor and turbine sample systems)and 0.209 in (radwaste sample system)is used.The tubing is ASTM A213 Grade Type 316 stainless steel rated at 4,261 psig at 1,000 F.These maximum working conditions exceed the design condition of all sample sources.Incoloy 825 tubing is used on the e Amendment 23 9.3-15 December 1985 Nine Mile Point Unit 2 FSAR radwaste evaporator sample;lines.This material was selected due to its corrosion resistance to sodium sulfate solution being sampled.Parent process piping is fitted with sample probes or wall taps in turbulent flow zones to ensure representative samples.All continuous samples have bypass purge lines around the analyzers.
Grab samples are purged to hooded sinks.9.3.2.3 Safety Evaluation The process sampling systems are not required to function during or following an accident, nor are they required to safely shut down the reactor.9.3.2.4 Inspection and Testing Requirements Nearly all process sampling system components are used regularly during power operation or during shutdown;thereby providing continuous assurance of system availability and performance.
Routine calibration checks are performed on the continuous analyzers to ensure accurate indications and alarm functions.
9.3.2.5 Instrumentation Requirements 9.3.2.5.1 Reactor Plant Sample System Instruments and controls are provided, to monitor the quality of reactor coolant and various reactor plant fluid systems.The controls described below are situated locally'.Except where noted, the monitors described below are located in the main control room.The control logic is shown on Figure 9.3-6.>>(Temperature and flow rate indicators are provided on the sample panel in the reactor building to indicate that samples are properly conditioned for sampling purposes.Sample valves for sampling lines are opened and closed manually.The sample valves for the RHR heat exchangers and the reactor recirculation inlet samples automatically trip closed on high sample temperature to prevent excessive downstream temperature in the sample line.Amendment 23 9.3-16 December 1985 Nine Mile Point, Unit 2 FSAR The diesel generator building drain sump pumps discharge to the storm sewer through the diesel generator yard area oil separator by a hand-operated valve.Monitorin Reactor Buildin E ui ment and Floor Drains Recorders are provided for: 1.Drywell floor drain tank level.2.Drywell floor drain pump flow.3.Drywell floor drain leak rate.4.Drywell equipment drain tank level.5.Drywell equipment drain pump flow.6.Drywell equipment drain leak rate.Alarms are provided for: 1.Reactcr building floor drain leakage high.2.Reactor building floor drain temperature high.3.Drywell floor drain tank level high-high.

The solution can be diluted with water to within 6 in of the overflow level volume to allow for evaporation losses or to lower the saturation temperature.
The tank may contain boron solution from a minimum volume of 4,418 gal (net low level volume)to a maximum of 4,815 gal (net high level volume)based on a zero level of 5.1 in above the centerline of the outlet.The minimum temperature of the fluid in the tank and piping is consistent with that obtained from Figure 9.3-19 for the solution temperature.
The saturation temperature of the recommended solution is 60 F at the low level alarm volume.Equipment containing the solution is installed in an area in which the air temperature is maintained within the range of 70 F to 100 F.An electrical resistance heater system provides a backup heat source that maintains the solution temperature between 75 F (automatic operation) and 85 F (automatic shutoff)to.prevent precipitation of the sodium pentaborate from the solution during storage.High or low temperature, or high or low liquid level, causes an alarm in the main control room.The entire system is located within the reactor building, so it is unaffected by cold weather.The positive displacement pumps are sized to inject the boron solution (minimum 41.2 gpm per pump)into the reactor within a specified time period, independent of the amount of solution in the tank.The pump and system design pressure between the explosive valves and the pump discharge is 1,400 psig.The two relief valves are set to open at 1,387 psig with no back pressure.To prevent bypass flow in the event that a pressure relief valve fails and opens, a check valve is provided downstream of each relief valve in'each pump discharge line.The two explosive-actuated injection valves provide assurance of opening when needed and ensure that boron does Amendment 27 9.3-31 July 1986 Nine Mile Point Unit 2 FSAR not, leak into the reactor-even when the pumps are being tested.Each explosive valve is closed by a shear.plug in the inlet chamber.The plug is circumscribed with a deep groove so the end readily shears off when pushed with the valve plunger.This opens the'nlet hole through the plug.The sheared end is pushed out of the way in the chamber and is shaped so it does not block the ports after release.The shearing plunger is actuated by an explosive.
charge with dual ignition primers inserted in the side ch'amber of the valve.Ignition circuit continuity is monitored by a trickle current, and an alarm occurs in the control room if either circuit opens.Indicator lights show which primary circuit opened.Signals from the RRCS can automatically initiate the.SLCS by actuating both loops.The SLC'system can also be actuated manually by two keylocked spring-return switches which ensure that switching from the NORMAL position to RUN position is a deliberate act..Operation of either switch starts an injection pump and simultaneously opens its respective explosive valve and storage tank outlet valve..The initiation generates a signal to.close the reactor water cleanup system isolation valve to prevent loss or dilution of the boron.This isolation signal is sealed-in during SLC operation and remains sealed-in until reset by operator action.A light in the control room indicates that power-is available to the pump motor contactor and that the contactor is deenergized (pump not running).Another light indicates that the contactor is energized (pump running).Storage tank liquid level, tank outlet valve position, pump discharge pressure pump flow, and loss of continuity of the explosive valves indicate that the system is functioning.
Pump discharge, pump flow, and valve status are indicated in the main control room.Equipment drains and'ank overflow.are not piped to the radwaste system but to a separate container (such as.a 55-gal drum)that can be'"removed and disposed of independently to prevent any trace of boron f'rom inadvertently reaching the reactor.Table 9.3-2 contains the process data.for the various modes of operation of the SLC system.Seismic category and safety class.are included in Table 3.2-1.Principle's of system testing are discussed in Section 9.3.5.4.Amendment 18 9.3-32=March 1985 Nine Mile Point Unit 2 FSAR THIS PAGE INTENTIONAjLY BI.ANK Amendment 18 9.3-33b March 1985 Nine Mile Point Unit 2 FSAR The SLC equipment required for injection of neutron absorber solution into the reactor is designed as Category I for withstanding the specified earthquake loadings (Chapter 3).The syst: em piping and equipment are designed, installed, and tested in accordance with requirements stated in Section 3.9B.The SLC system is powered normally from offsite power sources.In the event of a plant offsite power failure, the pumps, valves, and controls necessary to assure boron injection are powered from the standby diesel generators.
The heaters are manually connectable to the standby diesel generators.
The pumps and valves are powered and controlled from separate divisional buses and circuits.The SLC pumps have sufficient pressure margin, up to the system relief valve setting of 1,387 psig with no back pressure to assure solutioninjection into the reactor above the normal pressure in the bottom of the reactor.-The reactor safety relief valves begin to relieve pressure above approximately 1,100 psig.Therefore, the'LC positive displacement pumps cannot overpressurize the nuclear system.Only one of the two standby liquid control loops is needed for backup shutdown system operation.
If a redundant component (e.g., pump)in one of the two parallel loops is found to be inoperable, there is no immediate threat to shutdown capability, and reactor operation can continue during repairs.The time during which one of the two parallel loops may be out of operation is given in the Technical Specifications.
9.3.5.4 Testing and Inspection Requirements Testability of one pump at a time is possible while the reactor is in service.While one pump is being tested during reactor operation, the other pump is capable of in-Amendment 26 9'-34 May 1986}}
