Re: Extension for green ticket G20030384 We are requesting a 30 day extension for green ticket G20030384, which would change the EDO due date from 7/21/03 to 8/22/03. This GT is a letter sent to Chairman Diaz from Debbie Grinnell of the C-10 Research and Education Foundation, Newburyport, MA. Ms. Grinnell's concerns relate to the adequacy of SG tube inspections based on NRC Information Notice 2002-21 and J. Hopenfeld's Differing Professionial Opinions on the same subject. She is asking very detailed questions about SG tube inspections at Seabrook, requesting that the NRC order the industry to conduct adequate SG inspections, and requesting that the NRC issue a proposed rule to assure SG tube integrity.

Because of the extensive coordination necessary to address potential 2.206 implications, request for rulemaking, and to ensure we provide a response consistent with previous correspondence related to J.

Hopenfeld's concerns, we request the EDO due date be extended to 8/22/03.

I Guv Vissing - IP2-3503-DOC M-1.Ddf Paie I Guy Vissina - 1P2-3503-DOC M-l.odf Paae 1 Indian Point 2 Improved Technical Specification Conversion Project M.1 3.5.3: ECCS -Shutdown Category More Restrictive:

DOC Summary:

Establishes new requirement for two 50% capacity ECCS high head safety Injection pumps and one 100% capacity ECCS RHR subsystem (low head) pumps to be OPERABLE to be Operable In Mode 4 to ensure ECCS low Is available to the core following a DBA In Mode 4.

Description of Change CTS 3.3A.1 establishes requirements for ECCS train (pump) Operability only when the reactor is critical. These requirements are maintained In IP2 ITS LCO 3.5.2 which is applicable In Modes 1, 2 and 3.

IP2 ITS 3.5.3 establishes new requirement ior ECCS hi Mode 4. IP2 iTS 3.5.3 requires Operability of two 50% capacity ECCS high head safety Iniectlon (HHSI) pumps and one 100% capacity ECCS RHR subsystem (low head) pumps In Mode 4 to ensure ECCS flow Is available to the core following a LOCA In Mode 4.

IP2 ITS 3.5.3 establishes allowable out of service times for ECCS equipment when In Mode 4 as follows:

With one of the two required ECCS HHS subsystems Inoperable, the remaining HHS subsystem and the RHR subsystem maintain substantial capability for the mitigation of a large spectrum of both large and small break LOCAs In Mode 4. Therefore, a Completion Tre of 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months for restoration of the Inoperable subsystem Is warranted.

With both of the required ECCS HHS subsystems inoperable when In Mode 4. the plants capability to respond to a small brak LOCA Is significantly degraded.

Therefore, a Completion Time of 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months for restoration ensures that prompt action Is taken to provide the required cooling capacity or to initiate actions to place the plant In MODE 5. where an ECCS subsystem is not required.

With the required ECCS RHR subsystem Inoperable when In Mode 4, the plant Is not prepared to respond to a loss of coolant accident or to continue a cooldown using the RHR pumps and heat exchangers. The Completion Time of Immediately to Initiate actions that would restore at least one ECCS RHR subsystem to OPERABLE status ensures that prompt action Is taken to restore the required plant cooling capacity.

This LCO Is modified by a Note that specifies that an ECCS RHR subsystem may be considered Operable when during alignment and operation for decay heat removal, If capable of being manually realigned (remote or local) to the ECCS mode of operation and not otherwise inoperable. This allows operation In the RHR mode during MODE 4. The ITS Bases for this LCO also clarify that an HHSI subsystem may be considered OPERABLE when Injection capability Is blocked to meet requirements of LCO 3.4.12 If capable of being manually realigned to the ECCS mode of operation.

Justification for Change:

This change Is needed to ensure the availability of ECCS Injection capability and long term decay heat removal capability In Mode 4 because the potential for a LOCA still exists at reduced temperatures and pressures.

This change Is acceptable because single failures are not considered during Mode 4 operation, core cooling requirements lower than those following a DBA initiated from 100% RTP, and there is reduced potential for a LOCA event In Mode 4. Therefore, two 50% capacity ECCS high head safety injection pumps and one 100% capacity ECCS RHR subsystem (low head) pumps wUl ensure ECCS flow s available to the core following a DBA In Mode 4 even when the pumps are not algned for automatic Injection. This s tue because the stable conditions associated with operation In MODE 4 and the reduced probability of occurrence of a Design Basis Accident (DBA) allows the ECCS operational 10-Jul-2003 Revision 2 - Supplement 5

Indian Point 2 Improved Technical Specification Conversion Project requirements to be reduced.

The equipment required to be Operabie by ITS 3.5.3 Is sufficient to respond to a LOCA hI Mode 4 based assumptions used in the development of he foflowing P2 procedures:

Abnormal Operating Instruction (AOl) 4.2.2, FLOCA when RCS Temperature is at Least 200 F and Less Than 350 F;"

AOl 4.2.3, Transfer to Cold Leg Recircuiation During LOCA when RCS Temperature Is at Least 200 F and Less Than 350 F0 and, AOI 4.2.4. Transfer to Hot Leg Recirculation During LOCA when RCS Temperature is at Least 200 F and Less Than 350 F.'

These procedures are based on Westinghouse Abnormal Response Guideline (ARG)-2. Shutdown LOCA.L which Implements the conclusions identified in WCAP-12476. Evacuation of LOCA During Mode 3 and Mode 4 Operation for Westinghouse NSSS,' dated November 1991. WCAP-12476 used conservative assumptions and was determined to be applicable to all Westinghouse PWRs.

ARG-2 and WCAP-12476 address a LOCA that occurs In Mode 3 after the accumulators are Isolated or a LOCA hI Mode 4. These evaluations concluded that establishing safety injection from one high head SI pump within 10 minutes and flow from a second high head safety Injection pump within 30 minutes will successfully mitigate a small break LOCA (less than 6 inches In diameter).' The need for the second high head Si pump is limited to the case where the LOCA occurs when the RHR system Is aligned for decay heat removal. In this case, there Is a potential that RHR pumps are unavailable for safety injection because of void formation In the RHR inlet ine due to the temperature of the water In the RHR suction ne resulting in a saturation pressure that is less than the NPSH provided by the RWST.

ARG-2 and WCAP-12476 conservatively assumed that the total injection flow from the charging pumps and/pr high head safety injection pumps Is 200 gpm. (This conservatism was selected so that the analysis would apply to plants such as P2 that are designated as low head' plants because they do not credit the charging pumps for safety Injection.) WCAP-12476, Table 4-8, Small Break LOCA Analysis without RHR Pumps," Identifies the minimum safety injection flow for a 4-Loop plant with HHSI pumps as 610 gpm at a back pressure of between 100 and 300 psig.

IP2 has 3 High Head Safety Injection Pumps. UFSAR Figure 6.2-6 shows the pump performance curve for these pumps which Indicate that the following flow rates:

650 gpm per pump at 635 psig (1500 ft (water) head 400 gpm per pump at 1170 psig (2750 ft (water) head 200 gpm per pump at 1370 psig (1370 t (water) head Therefore, P2 meets WCAP-12476, Table 4-8 assumptions with only I HHSI pump; however, P2 ITS 3.5.3 conservatively requires two HHSI pumps available consistent with AOl 4.2.2. Additionally, for the small break LOCA with RHR. WCAP-12476 assumes that Mode 4 LOCAs are Initiated at a pressure less than 1000 PSIG which is consistent with typical Mode 4 conditions. Therefore, one HHSI pump wil provide greater than 400 gpm (the amount assumed for two pumps hI WCAP-12476). Additionaly, the IP2 RHR system relief valve Is set at approximately 450 psig. Therefore, If the LOCA occurs when P2 has RHR In decay heat removal mode, RCS pressure will be less than 450 psig and one HHSI pump will supply at least 650 gpm which is more than the volume assumed to be supplied by two pumps In the WCAP-12476 analysis. AdditonaRy, folowing ITS conversion, IP2 Technical Requirements Manual (TRM) 3.1.8 will require at least one Operable charging pump when in Mode 4 which will ensure the availability of an additional 80 gpm of high pressure Injection capability.

Post accident recirculation requirements for a Mode 4 LOCA are ensured by ITS 35.3 by requirements for the Operability of I RHR subsystem. Although the required RHR subsystem may be aligned for decay heat removal when hI Mode 4. availability of the RHR pump for post LOCA recirculation Is assured following both a large and a smal break LOCA. As discussed above, P2 HHSI njection capacity Is 10-Ju192003 Revision 2 - Supplement

Additionally, Step I of 1P2 AOI 4.2.2 requires that the RHR pump Is stopped Immediately to prevent damage there Is any Indication of loss of flow to the RHR pump suction during a large break LOCA. Finally, as discussed In the 1P2 ITS LCO 3.5.2 Bases, IP2 post LOCA recirculation requirements can be satisfied be either of the two RHR pumps or either of the two Recirculation pumps.

Although not specifically required to be Operable hI Mode 4, the redundant RHR pump and the two recirculation pumps would typically be available for recirculation the required RHR pump was unable to perform the recirculation function.
