( c Date: /2 - C 2 PART I (50.59172.48) - DESCRIBE THE PROPOSED ACTIVITY AND SEARCH THE PLANT AND ISFSI LICENSING BASIS (Resource Manual 53.1)
NOTE.- The "NMC 10 CFR 50.59 Resource Manual" (Resource Manual) and NEI 96-07, Appendix B. Guidelines for 10 CFR 72.48 Implementation should be used for guidance to determine the proper responses for 10 CFR 50-59 and 10 CFR 72.48 screenings.
Li Describe the proposed activity and the scope of the activity being covered by this screening. (The 10 CFR 50.59172.48 review of other portions of the proposed activity may be documented via the applicability and pre-screening process requirements in NP 5.1.8.) Appropriate descriptive material may be attached.
CR 01-2278, CR 01-3595 and LER 266/2001-005-00 identified an issue that could cause a common mode failure of all auxiliary feedwaier pumps. If an accident or event has occurred that has led to the loss of instrument air, then the auxiliary feedwater pump minimum recirculation control valves 1/2AF-4002 for 1/2P-29, AF-4007 for P 38A, and AF-4014 for P-38B will all fail closed. During this event, it will become necessary for operations to throttle back auxiliary feedwater flow to control steam gencrator.level, especially if all four auxiliary feedwater pumps auto start as designed. If care is not taken to ensure that the minimum recirculation valves are open, and the pump discharge valves are shut with no minimum flow path, then the pumps will dead head and fail in a very short time due to overheating. Currently, there is guidance in EOP 0, EOP 0.1, ECA 0.0, and AOP 5B to direct operations to verify adequate pump flow if instrument air has been lost before reducing flow to the steam generators, or to stop the pump.
To provide additional assurance that the auxiliary feedwater pumps will not be damaged on a loss of instrument air, backup air sources will be supplied to all minimum flow recirculation valves. These modifications are an enhancement that will reduce the core damage probability from a loss of instrument air and increase the time for an operator to take manual action to override the valves open. Instrument air accumulator tanks will be installed by MR 02-001 for the 1/2P-29 valves (I/2AF-4002), and the existing nitrogen backup system for the MDAFP discharge valves will be tied in by MR 01-144 for the P-3WAIB valves (AF-4007, AF-4014).
Currently, the auxiliary feedwater minimum flow recirculation valves do not have a safety function in the open position, however this function is a design function described in FSAR Section 10.2 and Technical Specification Bases B3.7.5. The basis for the recirculation valves not having a safety function in the open position is that all of the auxiliary feedwater pumps will have open discharge valves upon auto-start (even with a loss of instrument air), and thus the minimum flow recirculation line is not needed early in the accident or event. These minimum recirculation valves currently have an augmented quality function to open (by manual override) to ensure adequate flow though the associated auxiliary feedwater pump during an Appendix R fire within 45 minutes (per PBF-1515c Revhon0 10=2401 Re.fancc. NP 5.1.9
Point Beach Nuclear Plant SCR 2002-0010 10 CFR 50.59172.48 SCREENING (NEW RULE) Verfy SCR number -man pages Page 2 Calculation WE-0005-06), and the backup systems installed by these modifications may be credited to support this function.
These modifications will provide a sufficient secondary source of air or nitrogen such that these valves are able to operate for at least two hours stroking 10 times per hour if the regular instrument air system is disabled due to a seismic event, tornado, fire, or loss of offsite power. No changes will be made to the control circuitry of the valves, and they will still open automatically when the auxiliary feedwater pump flow drops below the setpoint, when the pumps are started, and when the pumps are secured.
MR 02-001 - I/2AF-4002 - TDAFP Mini Recirc Valves For l/2AF-4002, a stainless steel accumulator tank will be installed in each of the instrument air lines to the mini recirc.valves. Upstream of these tanks will be two check valves in series that will isolate the tank from the rest of the instrument air system. These check valves will be spring loaded and will shut on a very small differential pressure to ensure that the tank pressure will remain as high as possible when the instrument air pressure drops. The volume of the tanks will be approximately 150 gallons, which is greater than the required minimum volume determined by Calculation 2001-0056 to be needed to stroke each valve 10 times per hour for two hours. In order to reduce the amount of air required to stroke the valve and thus the tank size, the pressure regulator for the AF-4002 valves which is currently set at 85 psig. and will be re-set to 65 psig. The valve will still stroke full open at this pressure. Calculation 2001-0056 has also verified that these valves will pass full flow even when less than 20% open, since the flow restricting orifices 1/2RO-4003 govern the flow rate in the recirculation line and have the lowest flow coefficient.
The accumulator tanks will be ASME code vessels, designed to Section VIII, and will be rated to 200 psig.
These tanks will be installed in the north and south sections of the auxiliary feedwater pump room (not in the pump cubicles). The tank locations were chosen based on the best possible tubing run, and to limit obstructions to plant equipment. Isolation valves will be installed to permit replacement of the check valves should leakage or failure occur. The tubing will be configured such that system pressure can be used to test each the check valves, if necessary.
The new tubing will be routed through the wall that separates the IP-29 cubicle from the south section of the auxiliary feedwater pump room (Fuie Zone 3045). This is a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rated fire wall that is considered a partition within a fire zone.

MR 01-144 - AF-4007 and AF-4014 - MDAFP Mini Recire Valves The existing nitrogen supply systems for the AF-4012 and AF-4019 MDAFP Discharge Control Valves (one independent system for each valve) will be used to supply the AF-4007 and AF-4014 MDAFP Minimum
?tecirculation Control Valves. The existing instrument air isolation check valves AF-131/133 (for AF-4012) and AF-1511153 (AF-4019) and nitrogen tubing and tanks will be used for the AF-4007 and AF-4014 valves.
New tubing will be installed to connect the nitrogen supply tubing near the AF-4012/4019 valves downstream of the check valves to the AF-4007/4014 minimum recirculation valves. Also, a bypass line will be installed around the AF-133/153 check valves to allow the AF-1311151 check valves to be tested using system pressure, if necessary. The existing instrument air connections to the AF-4007/4014 valves will be capped.
The nitrogen system pressure regulators (PCV-4053/4058) are currently set to 60 psig, and will be re-set to 65 psig. This will increase the margin for stroking the recirculation valves open, although this is still less than the normal valve regulator setting of I00 psig. Calculation 2002-0002 has verified that these valves are full open at this pressure, and that they will pass full flow even when less than 20% open, since the flow restricting orifices RO-4008/4015 govern the flow rate and have the lowest flow coefficient in the recirculation line. This increase in pressure regulator setting will not affect the discharge valve positioners, since they normally operate with 100 psig instrument air, but only require 45 psig.
The existing nitrogen supply system installed by MR 97-038 consists of two nitrogen bottles, with one valved in and the other bottle maintained full in standby mode. When the aligned bottle pressure drops to the changeout point, the standby bottle is aligned, and the drain bottle is replaced with a full bottle. Calculation eF-ilSIcc Rei'slon 0 10/24/0 eeeneVlP51.
"PointBeach Nuclear Plant SCR 2002-.0010 10 CFR 50.59n12.48 SCREENING (NEW RULE) vef scR nmber onan page Page 3 2002-0002 determined the changeout pressure for the bottle that will supply 90 minutes of nitrogen to the discharge and minimum recirculation valves. Therefore, there is always greater than three hours of capacity available in the system at any given time, although operator action is required to align the standby bottle.
Although the AF-400714014 valves do not have a safety function to open, all components in the air supply line to the valve will be installed as safety related, since it will be part of the pressure boundary for the existing discharge valve backup system, which was installed safety-related by MR 97-038. Several existing instrument air components upstream of the solenoid valve that are not safety related will be reclassified as safety related. This can be done on the basis that these components have demonstrated adequate functionality over time, and these components will also be leak tested by MR 01-144. This is equivalent to qualification testing, and therefore these components may be dedicated. Furthermore, the dimensions of these components have been verified to be appropriate for the installation. Finally, the material acceptability will be evaluated based on a detailed walkdown.
Common Issues All new tubing and valves installed for both modifications will be stainless steel and have design ratings that are the same as or greater than the existing components. All new components will be installed using ASME B31.1.
All new tubing, valves, and accumulators will be analyzed as seismic Class 1. Standard wall mounted tube supports will be used and supported with Hild bolts into the walls of the auxiliary feedwater pump room..
Calculation 14410.11-NP(B)-001-XE Rev 0 (including Addendum A) provides a seismic basis for the use of tubing supports and a required spacing, and the limitations of this calculation shall apply to all tubing installation.
Supports for the pressure gauges for MR 02-001 will be designed in accordance with Calculation S-09334-266 IA.2 Rev 2. The floor supports for the accumulator tanks were seismically analyzed by Calculation 2001-0001.
Portions of the system not covered by any calculation will receive a SQUG walkdown to ensure seismic adequacy.
Currently the nitrogen system AF-133/153 check valves are safety-related and in the IST program. They are leak tested quarterly by IT 10, and are also tested by IT 10A and IT 10B. The upstream check valves AF-1311151 will not be tested periodically, but a bypass line is being installed to facilitate testing, should it be necessary in the future. The check valves for the instrument air accumulator will not be part of the IST program, nor will they be periodically tested. They will be tested as PMT for the modification. Since the accumulators are not supporting a safety function of the AF-4002 recirculation valves, then there is no need to periodically test these check valves.
The specified two hour time duration on the backup systems is not a licensing basis requirement. There is a one hour required coping duration for the Station Blackout event (FSAR Appendix A.1), and a 45 minute requirement for Appendix R (Calculation WE-0005-06). but no other time requirements are specified. Two bhlrs was chosen conservatively to be enough time to allow an operator to be dispatched to the auxiliary feedwater pump room to take manual action if necessary, and to bound current and future requirements. The sizing of these systems with a two hour capability does not imply a new licensing basis requirement to supply these valve for two hours.
The minimum recirculation valves were assumed in each of the calculations to stroke 10 times per hour. This is a conservative estimate that was also used in the original calculation for the MDAFP discharge valve nitrogen backup system (Calculation M-09334-266-IA.1). Simulator runs have confirmed that this is very conservative since operations personnel will typically attempt to maintain the steam generator levels steady by balancing auxiliary feedwater flow with steam flow. See Calculations 2001-0056 and 2002-0002 for more details on this assumption.
Modifications MR 01-144 and MR 02-001 and the issue documented in LER 2001-005-00 will necessitate a revision to FSAR Sections 9.7 (Instrument Air) and 10.2 (Auxiliary Feedwater) and to Technical Specification Bases 3.7.5 to clearly reflect the design function of the minimum recirculation valves to open and to describe the backup air supplies installed by these modifications.
Necessary updates to Appendix R documents to take credit for the backup systems will be evaluated by a separate 50-59. However, this 50.59 can provide the basis for the backup systems to perform this function.

If ALL the questions in Part II are answered NO.,then Part ITM is [0 NOT APPLICABLE.
Answer the following questions to determine if the activity has an adverse effect on a design function. Any YES answer means that a 10 CFR 50.59 Evaluation is required: EXCEPT where noted in Part If.3.
11M.1 CHANGES TO THE FACILITY OR PROCEDURES YES NO QUESTION
[]I Does the activity adversely affect the designfuiutionof an SSC credited in safety analyses?
El [] Does the activity adversely affect the method of performing or controlling the designfunction of an SSC credited in the safety analyses?
If any answer is YES, a 10 CFR 50.59 Evaluation is required. If both answers are NO, describe the basis for the conclusion (attach additional discussion as necessary):
The modifications will improve the ability for the minimum flow recircuiation valves to perform their non safety.
related design function in the open position (A.2). Currently, this design function is completely provided by either the instrument air system or by manual operator action. These modifications will install backup systems to perform this design function after instrument air is lost before operator action is taken. These backup systems (nitrogen bottles and air accumulators) will always be available if the instrument air system fails, and will be isolated from the instrument air system with two check valves in series. The backup systems for the recirculation valves will be installed using safety-related components, even though they are not supporting a safety function for the minimum recirculation valves. The components for the MDAFP recirculation valves will be classified as safety-related since they are part of the nitrogen system pressure boundary required for the AF-4012/4019 valves. The components for the TDAFP recirculation valves will be installed as augmented quality, seismic Class 1. There will not be an adverse effect on the existing non safety-related instrument air system that currently supports this design function. The recirculation valves will need to operate at a lower air pressure of 65 psig, but the valves will still fully open at this pressure, and Calculations 2001-0056 and 2002-0002 has shown that the valves will pass adequate flow to perform this design function when they are only approximately 20% open. The net effect of these modifications is an improvement that results in a lower core damage probability (see NPM 2002-0030), and will ensure that the minimum flow recirculation valves have the capability to open and that the auxiliary feedwater pumps will not be damaged by operating at low flows. Therefore, design function A.2 is not adversely affected, and is actually enhanced. T1iis will provide the operators with additional time to diagnose the loss of instrument air and take action to properly control auxiliary feedwater flow and secure pumps if required.
Under most conditions when the auxiliary feedwater system is needed, the recirculation valves must be closed (design function A.1). The addition of these backup systems will not create a new failure mode that will fail the valve in the open position when it is needed to be shut. The source of the air is independent of the circuitry that would open and close the valve. The solenoid valves and associated circuitry that supply the air to the actuator are being not being affected, and are currently qualified as safety-related. The minimum recircnlation valves will still fail closed on loss of air, although this failure is less likely to occur with the installation of these backup systems. Therefore, these modifications will not have an adverse effect on design function A.I, and the likelihood that the valves will fail open has not been affected.
These modifications will not affect the auxiliary feedwater pressure boundary in any way, and thus design function A.3 is not adversely affected. The modifications will only involve the instrument air and nitrogen systems that actuate the minimum recirculation valves and the MDAFP discharge valves.
The air accumulators for the TDAFP recirc valves installed in the instrument air lines will not adversely affect any of the design functions of the instrument air system (C.1 through C.6). Once the accumulators have been pressurized, there is no additional long-term loading on the system required by installing accumulator tanks. The tank will not affect the operation of the other safety related accumulators or nitrogen bottles anywhere in the instrument air system.
The accumulator tanks and all new tubing will be installed and anchored as seismic Class 1, which will preclude interactions with other plant equipment.

Point Beach Nuclear Plant SCR 2002-0010 10 CFR 50.59/72.48 SCREENING (NEW RULE) Veify SCR number on all page Page 8 The nitrogen tie in for the MDAFP recirc valves will utilize the existing nitrogen backup system for the MDAF'P discharge control valves. Calculation 2002-0002 was performed to show that the existing nitrogen bottles are adequate to supply nitrogen to stroke the minimum recirculation valves and the discharge valves, with no additional bottles necessary, for two hours. Nitrogen bottle changeout at a pressure that ensures 90 minutes from one bottle with a second full bottle available will not change from current practice, other than the changeout pressure will be reduced, which is an improvement. There will be a negligible effect on the discharge valves stroke time to close by opening the recirculation valve with the same system. Furthermore, there are currently no stroke time acceptance criteria for the discharge valves opening and the recirculation valves closing. Since the calculation has shown that the existing system can handle the additional demand, there is no adverse affect on the discharge valves, and there is therefore no adverse effect on design function C.4. The backup nitrogen systems for the MDAFP discharge valves will still be fully capable of supporting the design functions of the MDAFPs and the auxiliary feedwater system (functions B.1 through B.7).
All new components, including the new tubing, valves, and accumulator tanks will be designed as seismic Class 1.
Therefore, the components installed by MR 01-144 and MR 02-001 will not adversely affect the seismic design functions of any components or systems in the auxiliary feedwater pump room (design function DI2) and the auxiliary feedwater system (design function B.6).
The new components will not affect the ability of the auxiliary feedwater pump room walls to act as 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rated fire barriers (design function D.1). No additional combustible loading is being added to the auxiliary feedwater pump room (Fire Zones 304N; 304M, 304S).
