Introduction to the 1993 Annual 10CFR50.59 Reggrt '
l 10CFR50.59 states: l (a) (1) The holder of a license. . .may (i) make changes in I the facility as described in the safety analysis report, (ii) !
make changes to the procedures as described in the safety l analysis report, and (iii) conduct tests or experiments not described in the safety analysis report, without prior ,
commission approval, unless the proposed change, test or experiment involves a change in the technical specifications i incorporated in the license or an unreviewed safety question. l l
It also states: )
(b) ...The licensee shall also maintain records of tests and I experiments carried out pursuant to paragraph (a) of this l section. These records shall include a written safety evaluation which provides the bases for the determination that the change, test or experiment does not involve an unreviewed safety question. The licensee shall furnish to (the NRC)..., ,
annually..., a report containing a brief description of such l changes, tests, and experiments, including a summary of the safety evaluation of each.
Unless otherwise noted, each safety evaluation concluded that the subject change, test or experiment did not:
+ Increase the probability of occurrence or the consequences of an accident or malfunction of structures, systems, or I components important to safety previously identified in the FSAR;
+ Create the possibility of an accident of or malfunction of a different type than any previously evaluated in the FSAR;
+ Reduce the margin of safety as defined in the basis fce Technical Specifications; And therefore, do not involve an unreviewed safety question as defined in 10CFR50.59.

- JAF-SE-89-084 Rev. O MISCELLANEOUS UPGRADE TO THE CD HANDLING l AND REFUELING EQUIPMENT The purpose of this modification was to replace the exiating 2 unit pushbutton pendant with a water tight 3 unit pendant which i includes an emergency stop button. This pendant controls the l CW/CCW rotation of the CRD handling platform (undervessel l carousel). This modification also upgraded the reactor cavi'y c '
lights to 2000 watts supplied from new 20 amp receptacles. l This modification does not represent any changes to the respective systems' function or configuration. The modificatians upgrades certain components in response to their application, such as the wet environment under the vessel for the pushbutton I pendant and the increased wattage required of the receptacles and i lights. These replacement components will perform the same j function as the previous components. As a result of being better ;
suited for the specific applications, the replacement pendant l station and receptacles will decrease the probability of a )
failure of these components.

, JAF-SE-89-132 Rev. 2 REPLACEMENT OF SERVICE WATER PIPING j AT RBCLCW SYSTEM HEAT EXC.4ANG398 j The purpose of the modification was to replace the Service vatm1 piping downstream of the Reactor Building Closed Loop Coelity:
Water System Heat Exchangers 15E-1A, 1B, and IC.
j This modification replaced the existing carbon steel pipir.g from the outlet of the RBCLCWS heat exchangers up to and inclnling the 45 degree elbow at Elevation 317'-4" with chrome-moly piping. No rerouting of piping or revisions to the number and location of
- pipe supports was required. Chrome-moly piping provides improved resistance to erosion and corrosion.
l New 150 lb. carbon steel slip-on flanges have been installed on j the heat exchanger nozzles to mitigate any possible detrimental effects on the heat exchanger due to code required post weld heat t treatment of carbon steel to chrome-moly welds.
! This modification also installed two new flanges on line 20"-WS-j 151-34 at Elevation 317'4" just downstream of the last 20" 45
! degree elbow in the Reactor Building. The installation of these flanges allows compliance with the Technical specification requirements of paragraph 3.7-C and 1.0-S for maintaining
, secondary containment integrity, if required, during the installation of this modification. Secondary containment j integrity would be maintained by the installation of a blank
- between the flanges.
i The installation of the replacement piping required the isolation
! of service water to the RBCLCW heat exchangers resulting in loss of the RBCLCW system. A Temporary modification to provide
- cooling water to various RBCLCW system loads that require cooling i during this outage as required. ,
[ l There are no unreviewed safety questions pursuant to 10CFR50.59. i Page 10

Modification: F1-89-092 JAF-SE-90-009 Rev. 1 SPARE TRANSFORMER FOUNDATION The purpose of this NSE was to evaluate the potential safety I impacts associated with the installation of the foundation for the spare reserve, normal and main transformers. The scope of this NSE is limited to evaluation of the foundation and associated power feed for the transformer control box heaters and )
fans. The transformer equipment to be stored on the foundation '
are not part of this NSE. Temporary utilization of the area for storage of plant waste oils was also evaluated.
In order to prevent a pessible long forced outage, procurement of a spare reserve station transformer is planned. In the future, NYPA expects to also purchase spare normal and main transformers.
The foundation has been sized to adequately store all three (3) transformers. Since the transformers' oil reservoirs will be full during storage, the design will provide for oil containment in the unlikely event of a rupture of oil tanks. Should this occur, oil will be collected in a sump and pumped out using approved means.
The foundation is isolated from the main plant and is self-sufficient, with all electrical utilities required to maintain the reserve station transformer in storage.
It is therefore concluded that this modification does not involve an unreviewed safety question pursuant to 10CFR50.59.

Attcchment 1 Modification: Mi-88-049 JAF-8M-90-069 Rev. 1 DISABLING OF VALVE ACTUATORS 67TCV-141 &
142 (OP) AND REMOVAL OF TEMP.
CONTROLLERS 67 TIC-141 & 142 The purpose of this modification was to disable two temperature control valve actuators for 67TCV-141 & 142, which leaves the valves in their normal fail-open position, and remove the two associated indicating temperature controllers 67 TIC-141 and 142 located in the pipe and cable tunnels. The valve actuators were obsolete and would have required total valve / actuator assembly replacement to achieve operability.
A heat balance calculation for the tunnels has shown that temperature control of the ventilation air flow is not necessary if the valves are left in an open position to permit full service water flow through the two ventilation system cooling coils 67E-11 and 14.
Calculation JAF-CALC-TBC-00839 shows that under normal plant conditions, the tunnels will maintain a minimum temperature of 40*F with an outside air temperature of -15*F.
This modification does not involve an unreviewed safety question pursuant to 10CFR50.59.

Attcchacnt 1 Modifications M1-90-176 JAF-BE-90-084 Rev. O INSTALL BAMPLE CONNECTIONS FOR INSTRUMENT AIR SYSTEM QUALITY TESTING The purposa of this modification was to install test connections downstreau of the following root valves: 39 BAS-400, 39IAS-66, 29IAS-120, 39IAS-2179. The test locations consist of an isolation valve, and quick connect fitting. These valves shall be tagged "for air quality testing only" to prevent inadvertent i uses of instrument air. l JAF has committed to ensuring that the Instrument Air System air quality meets the Instrument Society of America standard for air quality, ISA S7.3. To meet this commitment JAF Radiological and Environmental Department personnel have issued procedure PSP-29 to test the air quality at various locations. This modification evaluates the installation of air test connections to facilitate the air testing described in PSP-29.
This modification involved the addition of tubing and valve downstream of normally closed Instrument Air System branch isolation valves. The Instrument Air System and the subject valves are Quality Assurance Category II/III non-seismic and do not perform a safety function. The location of the new tubing and components was reviewed to assure that no safety related equipment would be affected by this modification. The addition of the valve and quick connects for testing did not change the function of the air system or the subject root valves. The location of the test connections and the use as described in the test procedure PSP-29 was reviewed to ensure that the instrument air supply to other components was not affected.
There is no unreviewed safety question pursuant to 10CFR50.59.

Attcohn nt 1 Nodification: F1-90-195 JAF-SE-90-087 Rev. 1 REPLACRNENT OF REACTOR RECIRCULATION WATER 8 AMPLE LINE CONTAINNENT ISOLATION VALVE 8 02-280V-39 AND 40 WITE 02-2AOV-39 AND 40 The purpose of this modification was to replace Reactor Recirculation Water Sample Line containment Isolation Valves 02-2SOV-39 (Line No. 1"-WH-1504-14) and 02-2SOV-40 (Line No. 3/4"-
WM-1504-14), at Penetration X-41, with new air operated valves in the existing location of the SOVs.
In addition to replacing containment isolation valves with new air operated valves that meet the LLRT criteria of Procedure ST-39B and 10CFR50, Appendix J, this modification also restored line 3/4"-WH-1504-14, (which was cut and capped in the Reactor Building) to its original design configuration so that the flow to the Crack Arrest Verification (CAV) System and the Sample Sink was restored.
All work was designated as QA Cat. I, with the exception of piping downstream of 02-2AOV-40 and air supply line to 02-2AOV-40, which were designated as QA Cat. II/III.
There is no unreviewed safety question pursuant to 10CFR50.59.

I Attcchacnt 1 Modification: M1-91-004 JAF-8E-91-030 Rev. 1 CHEMICAL DECONTAMINATION - ADDITION ,
OF PERMANENT PIPING AND VALVE -
ADDITION OF OONCRETE BUILDING The purpose of this modification was to provide permanent piping l connections on the Reactor Water Recirculation and RWCU suction piping and a precast concrete structure to house components for chemical decontamination. The chemical decontamination process was not addressed in this modification, only the permanent modification to support the process. [
The Reactor Recirculation system including the affected branch lines is defined as QA Category I in accordance with JAF FSAR Section 12.2.3. The addition of piping and valves to RWR branch j connections will not alter or impact system operation. The newly installed valves will remain closed and flanges will remain blanked during normal plant operation.
The ultimate objective of the chemical decontamination of various systems was to reduce overall man-rem exposure. During the modification to provide chemical injection pathways to j decontaminate the piping systems, a minimum amount of work was i performed in order to maintain man rem exposures ALARA.
The addition of pipe support to each of the branch connections ,
will reduce the additional pipe stresses imposed due to addition of valve weight onto the branch piping and will ensure pipe l stresses to be less than the code allowables. !
I To facilitate the chemical decontamination, a precast concrete l building structure has been installed adjacent to the standby gas j treatment building. This precast building was designed to. 1 provide radiation shielding and containment for the ion exchange columns and their associated equipment which are used in the decontamination process. '
Leak Testing of the new assemblies will be performed in accordance with the JAF FSAR and applicable code requirements of ANSI B31.1 (1967) and ASME Section XI (1980 Edition thru winter 1981 addenda).
The safety evaluation concluded that the modification did not involve a change in the Technical Specification or an unreviewed safety question pursuant to 10CFR50.59.

I Attcchm0nt 1 Nodification: F1-90-171 JAF-SE-91-035 Rev. 1 REPLACEMENT OF SERVICE WATER PIPING AT RBCLCW SYSTEM HEAT EXCHANGERS j i
i This modification replaced a portion of the existing 20" carbon l steel supply header and the 12" carbon steel supply piping to the RBCLCW heat exchangers with new chrome-moly piping of the same size and schedule. The chrome-moly piping provides improved resistance to erosion and corrosion.
New 150 lb. carbon steel slip-on flanges have been installed at the heat exchanger nozzles to mitigate any possible detrimental effects on the heat exchanger due to code required post weld heat treatment of carbon steel to chrome-moly welds.
The installation of this modification does not affect any safety related components or systems. Equipment for this modification did not require environmental qualification nor vill this modification have any affect on existing environmentally qualified equipment.
There is no unreviewed safety question pursuant to 10CFR50.59.

Att0chment 1 Modification: M1-90-233
- JAF-8E-91-050 Rev. O FEEDWATER NO2ZLE MONITORING SYSTEM The purpose of the modification is to measure the temperature of l the feedwater nozzles. Monitoring the temperature will provide I the input data to analyze the leakage flow rate of the feedwater sprayer / thermal sleeve. Excessive leakage flow past the thermal l sleeve can cause feedwater nozzle cracking due to thermal fatigue :
cycling. I The scope of the modification was to install the feedwater temperature monitoring system which consists of RTD's and a i recorder. ;
l This modification shall remain installed for a period of five years.
Three (3) RTD's were installed on each of four (4) feedwater nozzles. They are strapped to the outside surface of the feedwater nozzles with stainless steel bands and they are located as close to the nozzle forging radius as possible. The present pipe insulation was removed to facilitate RTD installation and re-installed.
The feedwater monitoring system has been used in other BWR plants as justification for delaying the inspection requirements of NUREG 0619 (BWR Feedwater Nozzle Cracking). NRC has recognized the feedwater leakage monitoring system as a potential alternative to in-vessel inspections (NRC Docket Number 50-263).
The components have no safety function. They are not listed in the Technical specification. They are also QA Category II/III.
A material component evaluation determined that the non-nuclear grade components utilized in this modification will survive the normal temperature and radiation environments of the drywell area, for the duration of the installation stay.
JAF-CALC-FWS-00257 determined that the components and its associated devices will survive the designed seismic event and will not affect other safety related components in the drywell area.

Attnehment 1 Modification: M1-91-179 JAF-SE-91-071 Rev. O ISOLATION OF ELECTRIC BAY UNIT COOLERS FOR APPENDIX R FIRE 8 This modification modified existing circuitry for system 67 unit cooler 16A & B fans in order to maintain remote operation in the event of fires in the Main Control Room or Turbine Building.
Prior to this modification, the control circuitry was tied together in a common enclosure causing concern that a fire in either location could cause short circuiting, resulting in a loss of control power to both unit coolers.
Activities accomplished included disconnecting, and sealing and sparing cables. Associated jumpers were added to maintain circuit integrity and maintain auto-start function.
This modification will resolve a 10CFR50, Appendix R/ Fire Protection issue by ensuring the 67UC-16A fans will remain operable in the event of a fire in the Turbine Building and the 67UC-16B fans will remain operable for a fire in the Main Control Room.

1820 light bulbs of higher wattage. The type 1820 light bulbs will provide increased luminescence of the annunciator windows for the operators. To compensate for the increased power i requirements. (13) power supplies have been installed in panel 09-43. This resulted in additional wiring in panel 09-43 and in the associated Control Room panels.
Replacement of the existing Main Control Room panel annunciator window light bulbs was necessitated as a result of the implementation of F1-87-061 IP #7 which prioritized the Main Control Room annunciators by installing colored boots on certain existing annunciator window bulbs. Along with the installation of the colored boots, new annunciator window light bulbs were installed to provide the required brightness of the color coding.
The replacement light bulbs were of increased wattage and the existing power supplies could not supply required power for the proper brightness of the booted annunciators.
The changes outlined in this installation procedure aids Control Room operators and improves the human factors aspect of the Main Control Room panels.

i The purpose of this modification is to resolve a temporary modification (#92-089) that was previously installed to protect three Reactor Fater Level Sensing Lines located on the Reactor Building 326' elevation from impact damage. This modification is I intended to incorporate the temporary modification into approved plant design documents. This involved the design, documentation, evaluation and verification required for a permanent solution to this outstanding temporary modification and justify its final disposition.
The temporary modification fabricated and erected a barrier of expanded metal, 2" x 2" x 3/8" angle and plate conforming to ASTM-A-36. The structure was secured to the concrete with Hilti II KWIK bolts per IS-S-02. Steel connections used bolting materials of ASTM-A-449 and ASTM-A-194 if welding was not practical. Welding of material conformed to JAF Welding Manual and painting of completed barrier was in accordance with IS-M-01.
A calculation was performed which was in accordance with A.I.S.C.
" Manual of Steel Construction" for deadweight & seismic consideration. This calculation verified the barrier design was adequate. (Ref. JAF-CALC-NBI-00477).
This existing barrier, which is a QA Category II/III seismic class II installation, will remain in place and all applicable plant drawings will be updated to reflect the as-built configuration.

10MOV-39A is a normally closed containment isolation valve and is i required to open during the Torus Cooling and Torus Spray modes l of RHR operation, t'
The replacement operator used for 10MOV-39A was originally purchased under P.O. Number S-91-16538 as a replacement operator for valve 27MOV-122 and was equipped with a spare 40 ft. lb. AC motor. The operator required a new stem nut which was compatible with the exiting valve stem and a new motor pinion and worm shaft to provide the approximate opening and closing times of the original operator. The operator spring pack was also changed by this modification.
A plate of compatible material was fabricated and welded to the l yokearm to permit mounting of the new operator. ;
1 Wm Powell Co., the valve manufacturer, prepared Seismic Report S- l 61020 MOD which contains the seismic calculations that demonstrate '

Attachacnt 1 Modification: M1-92-407 JAF-SE-92-245 Rev. O AUXILIARY BOILER VALVE UPGRADE 87LCV-109 j The purpose of this modification is to justify the upgrade of
, check valve 87AHB-287B to an nitrogen-operated valve which opens with high electric trap level via 87LS-131. This upgrade is i necessary since the Electric Trap becomes pressurized during high l nitrogen flowrates and steam flows through 87AHB-287B and pressurizes the condensate return lines to the temporary inerting boiler. This modification is part of the AQCR 92-377 resolution
, and will obviate the need for jumper 92-313 which upgraded the l nitrogen line to 87AHB-287B from copper to stainless steel '
. tubing.
! Valve 87AHB-287B (check valve) has been replaced with an air-operated globe valve (87LCV-109). This valve will be operated with Nitrogen from the CAD system. The associated solenoid operated control valve (87SOV-109) will open 87LCV-109 in response to a high level switch activation in the Condensate Receiver Electric Trap Tank (87TK-6) and will close when this level switch deactivates. Valve 87LCV-109 will fail closed to prevent high pressure upstream of 87LCV-109 from pressurizing downstream piping and returning steam to the temporary inerting boiler.
As part of this modification, plant valves 27 CAD-57A and B and 27 CAD 58A and B will be shown as normally closed to separate QA Cat. I and II piping. These valves are safety related, seismic class I valves which supply nitrogen to operate-Auxiliary Boiler valves and will only be opened during Drywell inerting (before startup) when an operator is present in the CAD building.

Attcchasnt 1 Modification: N/A JAF-SE-92-246 Rev. O WELD EXAMINATION AND POST WELD HEAT TREAT REQUIREMENTS l
The purpose of this safety evaluation is to analyze changes to i the weld examination program used to verify the pressure l integrity of piping and equipment pressure parts. These changes provide revised examination requirements for radiography, liquid penetrant testing, magnetic particle testing, ultrasonic testing i and visual examination requirements to be used following maintenance, repair, replacement and modification of existing plant systems or installation of new systems. In additicn, post weld heat treat (PWHT) requirements for P#1 carbon steel materials will be changed to meet ASME Section III criteria.
These changes will make the examination requirements consistent with those of the Inservice Inspection program currently in use at the plant. The current Inservice Inspection program conforms to ASME Section XI 1980 Edition through Winter 1981 Addenda.
The use of ASME XI-1980 Winter 81 addenda as the code of record, allows JAF to reconcile the past practice of using later editions of B31.1. This reconciliation is consistent with the requirements of ASME XI - IWA4120 and IWA7210. An engineering report, JAF-RPT-MISC-01130, details the technical justification that supports these changes.
Future weld examination requirements will be in accordance with ASME XI 1980 Edition Winter 81 Addenda and USAS B31.1-1967 Edition, A 1969 Addenda for the systems designated as ISI Class 1,2 and 3.
Future welding of Carbon Steel P#1 material may use the PWHT requirements of ASME Section III - 1992 Edition.

1 The control room annunciator is caused by a small amount of leakage past the blowdown flow control valve, 12FCV-55, that is l trapped by the two valves, 12MOV-56 and 57, creating a high I pressure condition in this volume causing the blowdown high pressure switch, 12PS-108 to alarm in the control room. This creates an undesirable " nuisance alarm" that distracts operations personnel.
This change in RWCU blowdown mode valve line up is acceptable on an interim basis provided the FCV leakage rate is monitored on a weekly basis and special condition tags are hung per WACP 10.1.2 l alerting operators of the abnormal valve line up. l It has been concluded that there is no unreviewed safety question pursuant to 10CFR50.59.

JAF-SE-93-016 Rev. O ACOUSTIC FISH DETERRENCE PROJECT 1993 The purpose of this project is to temporarily install and test an acoustic fish deterrence system on the offshore circulating water intake at the James A. FitzPatrick Nuclear Power Plant (JAF) from March through July 1993. The objective is to determine how effectively the system can reduce number of fish entering the intake and the number of fish subsequently impinged on the traveling water screens in the forebay.
The acoustic fish deterrence system will target the alewife, a species which comprises the majority of fish impinged on the
- intake screens at JAF annually. This species is preyed upon by salmon and trout that live in Lake Ontario. The New York State Department of Environmental Conservation considers the mortality of impinged alewives to be a potentially adverse environmental impact.
This test will also be used to confirm the results of a similar test performed from March thru July 1991 under temporary MOD 92-083 and Nuclear Safety Evaluation JAF-SE-91-037. The Circulating Water system is classified as QA Category II/III. The intake structure is classified as QA Category I.
The testing of the acoustic fish deterrence system did not have an adverse environmental or safety effect and does not involve an
, unreviewed environmental question based on testing under controlled conditions, and the SPDES permits for JAF.
There are no unreviewed safety questions pursuant to 10CFR50.59.

! The purpose of this safety evaluation is to remove Figure 9.10-3 from the FSAR. AQCR No.92-155 noted that FSAR Figure 9.10-3 i entitled " Plant Design Water Quality Conditions" was out of date and needed revision. The response to AQCR 92-155 was to initiate appropriate evaluations for the figure and text to ensure the work performed at JAF is appropriate and correct.
FSAR section 9.10 was submitted for revision to reflect the 4
! current design and operation of the makeup water treatment system l l and the figure was deleted. In reviewing the figure and the l 1
basis for it, the figure had no relevance to the section on I i makeup water treatment. Thus, there was no value to updating it
- to current practices, and the logical step was to remove it from ,
the FSAR. )
! l Figure 9.10-3 is being removed from FSAR Section 9.10 to delete I outdated and incorrect information. The correct information for original plant design is in reference 3 and 4 and should be included in DBD's as applicable. Current EPRI BWR Chemistry Guidelines are given in references 7 and 8. Plant procedures l
' incorporate these guidelines and their compliance has been l assessed by the corporate chemi-stry group. Removing Figure 9.10- i 3 will delete out of date information and has no impact on plant I operation or safety.

Attachasnt 1 Modification: N/A J4F-SE-93-022 Rev. O TURBINE SUPERVISORY INSTRUMENTATION (TSI) SYSTEN TRIP FUNCTION DISABLING l
The purpose of this safety evaluation is to address the acceptability of disabling the main turbine and reactor feed pump turbine (RFPT) high vibration trip function to allow maintenance l and calibration activities to be performed on the TSI System l bearing vibration detectors. I Disabling the TSI high vibration trip function is acceptable for maintenance and calibration activities. Adequate instrumentation and annunciation exists for monitoring and early detection of any abnormal bearing conditions. The probability of a catastrophic component failure causing rapid increase vibrations is considered to be very low relative to the duration in which the trip function will be disabled. j 1
The components and system addressed in this safety evaluation do not perform a safety related function nor do they support other systems or components required to support a safety related function.
Disabling the TSI high vibration trip feature does not involve an unreviewed safety question pursuant to 10CFR50.59.

, Ventilation system. Furthermore, the evaluation will provide the clarification needed to allow removal of the pressurization from j FSAR section 9.9.3.4.
J l
Normal air flow is routed from areas of lesser to progressively greater radioactive contamination potential prior to final exhaust. By shutting down System 67, this route is not affected.
l The greatest potential radioactive contamination area exists in i the Turbine building, which is under a negative pressure. If the Cable Tunnel Ventilation system were to fail or be taken out of service for maintenance, there would be no possibility of causing, either directly or indirectly, an uncontrolled relesce of radiation in excess of 10CFR100 limits.
In summary, operation of JAF without the cable Tunnel ventilation in service to pressurize the tunnels will not adversely affect continued safe operation of the plant and does not represent a potential unreviewed safety question pursuant to 10CFR 50.59.

For issues that relate to safety and policy, the nuclear portion of the Quality Assurance Department will report to the President of the New York Power Authority. Also, for issues that involve i salary reviews, hire / fire and position assignments, the Director of Quality Assurance will report to the President. The remainder of the department (non-nuclear) will also report directly to the President. This change is being made due to a temporary vacancy in the position of Senior Vice President - Appraisal and Compliance Services.
This safety evaluation is effective until either the position of Senior Vice President Appraisal & Compliance Services is filled ,
or a new safety evaluation is prepared for permanent j organizational changes. ;
1 The temporary administrative change does not have an affect on the overall day to day operations of the quality Assurance ,
Department nor does it alter the Power Authority's commitment to i maintain a management structure that contributes to the safe J operation and maintenance of the two Nuclear Power Plants, Indian Point #3 and James A. FitzPatrick.

Emergency Action Levels for the declaration of Unusual Event, Alert, and Site Area Emergency for both high and low lake level conditions are determined. The entry conditions are based on assuring the ability to safely shutdown the plant and assure for the post shutdown condition the functional capabilities of plant structures, systems, and components important to safety.
The entry conditions of EALs provides early notification to l operators for any condition of lake water level changes to safe operation of QA Category I components operating in the screenwell area, l
l The EAL's have been established at 252.5' maximum and 236.5' l minimum. These maximum and minimum Screenwell Water Levels were j established based on a combination of historical recorded lake l water level on which was super positioned the effects of storm, seiche, and rainfall.

JAF-8E-93-036 Rev. 0 VERIFICATION OF INTAKE STRUCTURE DE- 1 ICING HEATERS QA CATEGORY II/III The purpose of this safety evaluation is to support a revision to l FSAR Section 12.3.7 and to verify that the intake structure de- I icing heaters do not perform a function required for the safety l function of systems, structures, or components that are needed to maintain safe shutdown, remove residual heat, control the release of radioactive material or mitigate the consequences of an accident. l FSAR Section 12.3.7 statements regarding reverse flow will also be revised to describe the extent of gate positioning required to establish reverse flow.
Based on a review of the design of the de-icing heating system and intake structure, the safety system intake flow requirements, and the documentation that makes up the FitzPatrick design bases, it is concluded that the present non-safety related, QA Category II/III classification of the de-icing heaters is appropriate.
The results of laboratory testing and analysjs indicate that frazil ice blockage will not occur during plant shutdown (i.e.
circulating water pumps out of service) with or without the intake bar rack heaters in service and that sufficient emergency service water will be available should the heaters fail during an icing event with the plant in full power operation.

Attcchment 1 Modification M1-90-041 JAF-SE-93-041 Rev. O PROVIDE SHIELDING FOR SDIV LEVEL SWITCHES The purpose of this modification is to authorize the permanent installation of Temporary Modification 92-174. This Temporary
,l Modification was used to document the installation of a lead shield frame over the float cage (level pot) of the Scram ,
Discharge Instrument Volume (SDIV) level switches ( 03 LS-2 31A , B , E , l and F). This resulted in reduced radiation exposure to l technicians performing field functional tests / calibrations of I these level switches and transmitters in the SDIV protective enclosures (East and West).
This evaluation finds no conditions adverse to nuclear safety or Technical Specification design bases associated with the permanent installation of a frame to support lead shielding plates to existing support structures (level switch supports).
The lead shield structure is Q.A. Category II/III and its installation does not adversely affect systems, structure, or components associated with the safety objective and safety design bases as described in the FSAR or Technical Specifications. This modification will improve technician working conditions in a radiation area by improving access and reducing personnel

This safety evaluation analyzes the effect of adopting ASME B&PV l Code Case N-356, " Certification Period for Level III NDE Personnel Section XI, Divisions 1, 2, and 3," which extended the recertification period to five years.
This safety evaluation provides justification for updating the JAF FSAR to include the use of Code Case N-356.
Code Case N-356 has been endorsed (accepted) by the NRC for Implementation in Regulatory Guide 1.147, Rev. 9, April 1992, titled " Inservice Inspection Code Case Acceptability ASME Section XI Division 1." In addition, later editions of the Code (1983, Winter 1983 Addenda) Part IWA-2300 (a) (1) changed Level III personnel recertification period from three to five years.
Changing the recertification interval from three years to five years does not introduce any adverse effects to the examination process or Level III personnel qualification requirements since these areas are not changed. Extending the recortification period to five years also does not affect the Level III personnel's ability to perform their function, reduce their performance standard or degrade the quality of their work. This change is administrative in nature rather than technical and reflects practices accepted by the NRC and Nuclear Industry.
This change does not involve an unreviewed safety question pursuant to 10CFR50.59.

O TEMPOR)RY COOLING WATER SUPPLY VIA TEMPORARY PUNP INSTALLED IN THE INTAKE TO CONDENSATE PUNP MOTOR COOLER AND AIR COMPRESSOR DURING SERVICE WATER OUTAGE The purpose of this temporary modification is to provide a temporary supply of cooling water to the air compressors, 39AC-1A,B,C for plant outage periods when turbine building closed loop cooling system (TBC) is out of service. The cooling water is to be supplied from a temporary pump installed in the intake between the trash rack and the travelling screen. The plant will be in the cold shutdown condition for the duration of this temporary modification.
In addition to the above, this temporary modification will provide temporary cooling water to a condensate pump motor (33P-8A or B or C) via the same flow path as described above.
A backup pump will be installed in the intake next to the primary pump. This pump will duplicate the hose configuration of the primary pump all the way to the air compressors and the condensate pump in order to prevent a singlo hose rupture or a failure of the primary pump from causing a lous of cooling.
The use of a temporary supply to cool the above TBC loads results in system operation of the TBCLC, water treatment, breathing, instrument and service air system, and condensate system different than described in the FSAR.
This temporary mod, will not affect any safety related systems, or affect overall plant safety. The plant will be in the cold shutdown condition for the duration of the temporary modification.

Monitors (MSLRM) (17RM-251A,B,C, or D). This will allow technicians to isolate the cause of intermittent downscale ala rms .
This Safety Evaluation is being written for the following reasons: 1) I&C Departments ICSO-12 Generic Troubleshooting and Maintenance Procedure cannot be used for disconnecting the cables because it would require inserting a trip (half scram) into the affected RPS channel (s). (It is desired to maintain the monitors operable allowing work to be performed without inserting a half scram), and 2) WACP-10.1.3, Control of Jumpers, Lifted Leads, and Temporary Modifications must be used to document the
~
disconnection and Part IV-4 requires a Nuclear Safety Evaluation because it will result in operation different than described in the FSAR.
The disconnection of various inputs to the MSLRM recorder 17RR-252 and/or EPIC computer does not involve any conflicts with the FSAR, Technical Specifications, or licensing commitments. It will not affect the operation of the MSLRM's local (drawer) indication or trip functions. Since the recorder and EPIC provide indication functions only, in addition to that available at the front panel monitor, there are no effects on the safety functions of the system.

LEVEL BACKFILL MODIFICATION (F1-93-075) I l
The purpose of this Nuclear Safety Evaluation (NSE) is to '
demonstrate that preoperational test POT-02M will not affect plant safety.
This preoperational test has been divided into four (4) portions.
The first portion of the test placed all five backfill panels into service and induced transients into the CRD and backfill systems while the plant was in a cold condition to verify that no adverse operational transients would be generated different than shown in the model.
The second portion of this test monitored and recorded plant level, presscra and backfill flow rates during plant startup.
Thir. data will be utilized to determine the effect of the bacl: fill system on plant level and pressure during Control Rod movement and other transients caused by startup.
The third portion of this test induced limited transients into the CRD and backfill systems while the plant was at approximately 100% power to determine the system response to these transients.
Again plant level, pressure and backfill flow rates were monitored and recorded.
The final portion of the test which is now in progress, will monitor and record plant level, pressure and backfill flow rates for approximately six (6) months following 100% power testing.
This data will provide added assurance of system reliability.
This preoperational test is being performed to ensure that the Reactor Vessel Level backfill system installed as Modification F1-93-075 is operating properly and will provide validation of the model, confirming the results of other transients either too difficult or impossible to test (i.e., DBA large break LOCA, MSIV closure with SCRAM and SCRAM at full power).

Modification: M1-92-117 JAF-SE-93-089 Rev. 1 CORE SPRAY MINIMUM FLOW LINE PIPING AMD VALVE REPLACEMENT This modification replaced approximately five feet of 3" schedule 40 carbon steel ASTM A106 GR. B pipe with ASTM A376 TP316 "ainless steel pipe which is more resistant to cavitation. No tarouting of piping or revision to the number and location of i pipe supports was required. 14RO-27A will be relocated farther upstream of 14MOV-5A and 5B to decrease future cavitation damage to the motor operated valve internals.
Also, a Pacific 3" 300# carbon steel gate _ valve 14MOV-SA, weighing approximately 150# will be replaced with a 3" Borg Warner 300# stainless steel gate valves weighing 180#. The existing motor operator will be reused. This replacement is necessary because the existing Pacific gate valve was damaged beyond repair. The replacement valve is adequate for use as a core spray minimum flow isolation valve. ,
i Valve 14MOV5B was repaired as an option to replacement.
This piping replacement has been designed in accordance with ANSI B31.1 (2967 edition) and was installed and inspected in accordance with approved plant procedures.
The JAF Technical Specification has been revised to exempt core spray minimum flow branch piping from 10CFR50, Appendix J, Type A, B, or C Test, during the 1993 Maintenance Outage. JAF Technical Specification Amendment #196 has been issued. PCILRT of this piping will be performed prior to restart from the 1994 Refuel Outage.
This modification required pre-implementation review by the NRC because of a change to plant technical specifications but does not involve an unreviewed safety question pursuant to 10CFR50.59.

This evaluation addresses testing of the Core Spray (CS), System 14, valves 14MOV-5A " CSP Pump A Minimum Flow Isolation Valve" and 14MOV-5B " CSP Pump B Minimum Flow Isolation Valve". This test i
! approximates design basis differential pressure conditions across the valves to be tested, and then directs stroking of the valves.
Valve differential pressure will be determined from pressure measurements taken from permanent and temporarily installed plant instrumentation.
This Nuclear Safety Evaluation allows performance of differential pressure testing under flow conditions for valves 14MOV-5A and 14MOV-5B. Valve operator characteristics will be monitored and recorded using Liberty Technologies' " VOTES" test equipment.
I Performance of STP-14F and STP-14G has no adverse affects on the Core Spray System, its components, or other plant safety related structures, systems, and components. STP-14F and STP-14G may be preformed in any reactor operational mode when all required Technical Specifications are met.

j JAF-SE-93-092 Rev. 4 LIMITED OPERhTION OF REACTOR BUILDING CRANE The purpose of this safety evaluation is to address the safety
! concerns associated with continued use of the Reactor Building
< crane while having a mechanical deficiency in the bridge drive.
The scope of this evaluation is for the limited use of the crane for high priority tasks such as the spent fuel pool cleanup operation. Repair of the crane will be performed after j replacement parts are available.
The east-west travel of the Reactor Building Crane is controlled alone by the north drive wheel due to a mechanical drive deficiency in the south drive wheel assembly. The safety design basis of the crane pertains to its load carrying capacity, which is not reduced, nor jeopardized by the deficiency in the drive mechanism. The crane bridge will be restricted to its lowest speed (s) such that the effects of bridge skew or potential brake loss are negligible. Approved procedures address all phases of the crane use, and only qualified NYPA personnel operate the crane.
In conclusion, the limited use of the crane does not constitute an unreviewed safety question as defined by 10CFR 50.59 or involve significant hazards as defined in 10CFR50.92.

JAF-8E-93-094 Rev. 0 USE OF THE VACUUM DRYING SYSTEM FOR l REMOVING WATER FROM THE TN-RAM SHIPPING '
CASK ;
This safety evaluation documents that the use of the Vacuum '
Drying System (VDS) on the Refueling Floor (Reactor Building l Elevation 369) as described by JAF-1006, " Procedure For Handling )
and Loading the TN-RAM Shipping Cask" does not constitute an '
unreviewed safety question. l Irradiated material is to be shipped off-site to the disposal facility in several TN-RAM shipping casks. In order to meet the ;
federal regulations for use and transportation of the cask and '
the low-level waste disposal requirements, the VDS will be used.
The VDS is a portable, self-contained, free-standing auxiliary vacuum system used to remove residual moisture from a cask cavity by vacuum drying. In order to meet the liquid requirements, the cask has to be drained and dried. Residual water is evaporated by the VDS. A system diagram is provided in the procedure JAF-1006. The system is not interconnected with any other plant systems, therefore no system design changes will occur.
The operation of the Vacuum Drying System does not conflict with the description of the Radioactive Solid Waste system as stated in the FSAR, nor result in changes to the Technical Specifications, the Process Control Program, nor impact on any safety related or environmentally qualified structures, systems or components.
There is no unreviewed safety question pursuant to 10CFR50.59.

JAF-8E-93-097 Rev. O RP8 ISOLATION RESISTORS RELOCATION AND WIRES REROUTING IN 09-15 AND 09-17 l 4 PANELS This modification changed the physical arrangement of the RPS isolation resistors (05A-R3A through H) in panels 09-15 and 09-1
- 17. This corrected a deficiency in the GE circuit design and l
meets the current licensing basis of IEEE-279 and FSAR Sec. 7.2.2 such that no single failure within the RPS prevents proper RPS action. In addition, the power wiring between the scram 1 contactors for rod groups 3 and 4 was also modified.
This change to the physical arrangement for the second set of resistors does not increase the probability of occurrence of consequences of an accident or malfunction of equipment important to safety. In addition, it does not create the possibility of 3
an accident or malfunction of a different type, nor does it reduce the margin of safety as defined in the basis for any Technical Specification.

This modification involved the temporarily disabling of the auto-start circuit of the emergency supply fans 70FN-6A and 70FN-6B and running both emergency fans simultaneously during a LOCA.
The automatic start feature for these fans will be restored upon resolution of a separation concern.
As both fans will be running simultaneously during a LOCA, the i auto-start of the standby fan is not required. Running of two emergency fans will result in higher flow through the emergency ventilation system components. The components were determined to be adequate to handle the increased flow.
Radiological doses to the Control Room operators due to increased flow were evaluated and were determined to be below 10CFR50, Appendix A, Criterion 19 limits. Therefore, temporarily disabling the auto-start circuit for emergency fans is
- acceptable.
There is no unreviewed safety question pursuant to 10CFR50.59.

- N/A JAF-8E-93-104 Rev. O EVALUATION OF 27MOV-122 AND 27MOV-123 l CLOBE STROKE TIMES i This r.afety evaluation is written to document changes to the list of containment isolation valves in the Final Safety Analysis Report (FSAR) section 7.3 and Administrative Procedure (AP) -
01.04. Specifically, the Drywell Exhaust Bypass Inboard Isolation valve (27MOV-122) and Torus Exhaust Bypass Outboard Isolation valve (27MOV-123) will be listed as having a maximum closing time of 8 seconds instead of 5 seconds to account for actual closing times under degraded voltage conditions.
The 27MOV-122 and 27MOV-123 maximum close stroke times of 8 i
seconds are acceptable because: 1) the radiological consequences from the longer closure times are bounded by the
! accident analysis performed for a postulated LOCA during venting through the larger 24" (27AOV-113/ 27AOV-114) and 20" (27AOV-117/
27AOV-118) containment isolation valves; and 2) the l pressurization effects on the SGT system from the longer closure time are bounded by the analyses performed for a postulated LOCA during venting through the larger containment isolation valves.

f AttccanOnt 1 Modification N/A STP-466 JAF-SE-93-105 Rev. 0 SPECIAL TEST TO DETERMIME E8W SYSTEM RESPONSB RESULTING FROM THROTTLING 46E8W-5A/B/C/D The purpose of this special test is to collect ESW system hydraulic data to evaluate system response to throttling the Emergency Diesel Generator Jacket Water Cooler outlet isolation valves, 4 6ESW-5A/ B/C/ D. These valves are shown as " locked open" on FSAR Figure 9.7-2.
Spurious ESW strainer differential pressure alarms are commonly received whenever the system is operated with the ESW bypass isolation valves (4 6MOV-102 A/B) open. Data gathered during this test will aid in the formation of options to eliminate the spurious alarms.
The STP was performed following the completion of JAF modification S1-92-136. This modification replaced the existing cooler isolation valves with new Neles-Jamesbury butterfly valves. These Neles-Jamesbury valves possess more desirable throttling characteristics than their predecessors.
The performance of the STP is acceptable because it will not prevent the ESW system from performing its safety function. This is true because all ESW safety related loads will be receiving more flow than required by the FSAR during the performance of the special test.
Therefore, it has been concluded that performing the STP does not constitute an unreviewed safety question pursuant to 10CFR50.59.
