11.0 INTRODUCTION
By application dated March 8, 2005, Virginia Electric and Power Company (the licensee)requested changes to the Technical Specifications (TSs) for Surry Power Station, Unit Nos. 1 and 2 (Surry 1 and 2). The proposed changes would revise TS 3.6, "Turbine Cycle," to eliminate the inconsistency between the auxiliary feedwater (AFW) pump requirements and addan AFW flowpath allowed-outage time (AOT). In addition, the licensee proposed to revise the TS 3.6 requirements and the TS 4.8, "Auxiliary Feedwater System," surveillances forconsistency with NUREG-1431, Revision 3, "Standard Technical Specifications - WestinghousePlants."The licensee, in its submittal, discussed the various reasons for requesting these amendments.First, the current TS 3.6.F required action statement implies that at any time one AFW pump isinoperable, all three AFW pumps must be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or the unit must be placed in hot shutdown within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. This required action statement is not consistent with the operability requirements of TSs 3.6.B.1 and 3.6.C. TS 3.6.B.1 requires the two motor-driven AFW pumps to be operable prior to reactor coolant system (RCS) conditions exceeding 350 °F and 450 psig, but TS 3.6.C does not require theturbine-driven AFW pump to be operable until prior to reactor power exceeding 10 percent.
Therefore, from the time RCS conditions exceed 350 °F and 450 psig until reactor power exceeds 10 percent, only two motor-driven AFW pumps are required to be operable. Thus, the TS 3.6.F requirement to restore three pumps to operable status is not consistent with TSs3.6.B.1 and 3.6.C. Finally, TS 3.6.D requires AFW piping, valves, and control board indicationto be operable. However, there is no associated AOT and required action for the inoperabilityof these components.
2.0 REGULATORY EVALUATION
The Nuclear Regulatory Commission (NRC) staff evaluated the acceptability of the licensees'sproposed amendments based on the following regulations and guidance:Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix A, General DesignCriteria (GDC) 34 and 44 reflect the design basis for the AFW system with respect to decayheat removal. GDC 34 specifies, in part, that the system safety function shall be to transferfission product decay heat and other residual heat from the reactor core at a rate such that specified acceptable fuel design limits and the design conditions of the reactor coolant pressure boundary are not exceeded. GDC 44 for cooling water specifies, in part, that a system totransfer heat from structures, systems, and components important to safety, to an ultimate heatsink shall be provided. Both GDCs specify that suitable redundancy in components and features, interconnections, and isolation capabilities shall be provi ded.The licensee proposed changes to the Surry 1 and 2 TSs in order to establish consistency with NUREG-1431, as it relates to the Improved TS (ITS) program.
3.0 TECHNICAL EVALUATION
3.1 AFW System DescriptionThe AFW system provides a source of feedwater to the secondary side of the steam generatorswhenever the feedwater system is not available, thereby maintaining the heat sink capabilitiesof the steam generators. The system is relied upon to prevent core damage and RCSoverpressurization in the event of transients, such as, a loss of normal feedwater or a secondary system pipe rupture, and to provide a means of plant cooldown following a reactortrip. The AFW system for each unit consists of two motor-driven AFW pumps, each rated for 350gallons-per-minute (gpm) at 2730 feet of head, one turbine-driven AFW pump rated for 700gpm at 2730 feet of head, a 110,000 gallon emergency condensate storage tank, andassociated piping, headers, valves, controls, and instrumentation. The two motor-driven AFW pumps and a turbine-driven AFW pump provide for diversity of power sources to support the automatic actuation of the AFW supply. The motor-driven or turbine-driven AFW pumps provide adequate capacity to cool the RCS. The amount of AFW flow that is required is dependent upon the amount of decay heat being generated, the cooldown rate desired for theRCS, and the heat being added to the RCS by the operating reactor coolant pumps. Althoughthe flowpaths from the pumps to the steam generators include common piping, the configuration of the system provides two redundant flowpaths. For each unit, the componentsin one flowpath are supplied by the H emergency bus, while the other flowpath is supplied by the J emergency bus. The AFW systems for each unit are cross-connected to provideadditional redundancy in case a single event, such as a fire or a high energy line break, would disable the AFW system of one unit.3.2Proposed Changes to TS 3.6.A The licensee proposed to revise TS 3.6.A by consolidating the requirements for the main steamsafety valves (MSSVs) from TS 3.6.A, TS 3.6.B.3, and TS 3.6.D into TS 3.6.A. The licenseeaccomplished this by deleting the duplicate MSSV requirements contained in TS 3.6.B.3 andrelocating the associat ed system piping requirements for the MSSVs from TS 3.6.D to 3.6.A.The licensee's consolidation and relocation of the MSSV requirements did not result in anychanges to the requirements for the MSSV or associ ated system piping. The NRC staff hasdetermined that the relocation of these TS requirements has no impact upon the technicalaspects of the items that were removed or relocated. As such, the licensee's proposed changes are acceptable.3.3Proposed Replacement of TS 3.6.B The licensee proposed to renumber the current TS 3.6.B as TS 3.6.C and add a new TS 3.6.B. The revised TS 3.6.B will incorporate new AFW requirements and will read as follows:B.With Reactor Coolant System conditions less than 350 °F and 450 psigand the steam generators being used for heat removal, one motor driven auxiliary feedwater pump and associated flowpath shall be OPERABLE.The licensee's proposed changes to TS 3.6.B include the addition of new AFW pump andflowpath requirements if the steam generators are used for heat removal, when RCS conditions are less than 350 °F and 450 psig. The licensee stated that these new requirements in TS3.6.B are consistent with NUREG-1431. The NRC staff found this proposed TS revisionconsistent with NUREG-1431, and, therefore, acceptable. 3.4Proposed Changes to TS 3.6.B, TS 3.6.B.1, TS 3.6.B.3, and TS 3.6.B.4.a3.4.1 TS 3.6.B currently states:B.To assure residual heat removal capabilities, the following conditionsshall be met prior to the commencement of any unit operation that would establish reactor coolant system conditions of 350 °F and 450 psig whichwould preclude operation of the Residual Heat Removal System. The following shall apply:The licensee proposed to renumber TS 3.6.B as 3.6.C, capitalize the initial letters of the term
<reactor coolant system', and replace the phrase
<the commencement of any unit operation thatwould establish' with
<exceeding'. The NRC staff has determined that the changes to TS 3.6.Bhave no impact upon the technical aspects of the items that were removed. The renumbering and capitalization are considered editorial changes. As such, the licensee's proposed changes are acceptable.3.4.2TS 3.6.B.1 currently states:1.Two motor driven auxiliary feedwater pumps shall be OPERABLE. The licensee proposed to renumber TS 3.6.B.1 as TS 3.6.C.1 and revise the sentence asfollows:1.Three auxiliary feedwater pumps shall be OPERABLE.The licensee revised the renumbered TS 3.6.C.1 to require three AFW pumps to be operableprior to exceeding RCS conditions of 350 °F and 450 psig. The licensee stated that this requirement is consistent with NUREG-1431. The NRC staff found this proposed TS revision consistent with NUREG-1431, and, therefore, acceptable. 3.4.3TS 3.6.B.3 currently states:3.All main steam line code safety valves, associated with steam generatorsin unisolated reactor coolant loops, shall be OPERABLE with lift settings as specified in Tables 3.6-1A and 3.6-1B.The licensee proposed to delete TS 3.6.B.3, relocate the first sentence of the current TS 3.6.Dto TS 3.6.B.3, renumber TS 3.6.B.3 as new TS 3.6.C.3, and revise the new TS 3.6.C.3 to readas follows: 3.Two redundant flowpaths, including system piping, headers, valves, andcontrol board indication required for operation of the components enumerated in Specifications 3.6.C.1 and 3.6.C.2, shall be OPERABLE.The licensee revised the new TS 3.6.C.3 requirements for piping, valves, and control boardindication to more appropriately reflect AFW flowpath requirements, where the flowpath is defined as headers, valves, and control board indication required for operation. The licensee stated that the flowpath requirements are consistent with NUREG-1431. The NRC staff f oundthis proposed TS revision consistent with NUREG-1431, and, therefore, acceptable. 3.4.4 TS 3.6.B.4 a currently states:a. Two of the three auxiliary feedwater pumps on the opposite unit(automatic initiation instrumentation need not be OPERABLE) capable of being used with the opening of the cross-connect.The licensee proposed to renumber TS 3.6.B.4a as TS 3.6.C.4a and revise this section asfollows:a. Two of the three auxiliary feedwater pumps and the associated redundantflowpaths on the opposite unit (automatic initiation instrumentation need not be OPERABLE) capable of being used with the opening of the cross-connect.The licensee revised TS 3.6.B.4a. to establish consistency with the requirements of TS 3.6.C.3. The NRC staff considered this proposed change, an editorial change, and, therefore,acceptable. 3.5Proposed Changes to TS 3.6.CTS 3.6.C currently states:C.Prior to reactor power exceeding 10 percent, the steam driven auxiliaryfeedwater pump shall be OPERABLE.The licensee proposed to delete the current TS 3.6.C. As part of the deletion of TS 3.6.C , thelicensee has revised the current TS 3.6.B. Because of the changes discussed in paragraph 3.4, TS 3.6.C is no longer needed. The licensee proposed to delete the current TS 3.6.C toeliminate inconsistency between the AFW pump requirements and to be consistent withNUREG-1431. The NRC staff found these proposed TS revisions consistent withNUREG-1431, and, therefore, acceptable.3.6Proposed Replacement of TS 3.6.D TS 3.6.D currently states:D.System piping, valves, and control board indication required for operationof the components enumerated in Specifications 3.6.B and 3.6.C shall beOPERABLE (automatic initiation instrumentation associated with the opposite unit's auxiliary feedwater pumps need not be OPERABLE).The licensee proposed to relocate the following phrase in parentheses from the current TS 3.6.D to the current TS 3.6.G, and renumber TS 3.6.G as TS 3.6.I:(automatic initiation instrumentation associated with the opposite unit's auxiliaryfeedwater pumps need not be OPERABLE)In addition, the licensee proposed to replace the current TS 3.6.D with the following paragraph:D.With reactor coolant system conditions less than 350 °F and 450 psigand the steam generators being used for heat removal, if either the motor driven pump or the associated flowpath becomes inoperable, immediately initiate action to restore the inoperable equipment to OPERABLE status.The licensee relocated the current TS 3.6.D requirement to the renumbered TS 3.6.I with theopposite unit's AFW requirements. The remainder of the current TS 3.6.D is revised and relocated to the renumbered TS 3.6.C.3, as noted above in paragraph 3.4. Corresponding to new TS 3.6.D above, the licensee added new required actions to immediatelyrestore inoperable equipment if either the motor-driven pump or associated flowpath becomes inoperable with RCS conditions less than 350 °F and 450 psig and the steam generators are being used for heat removal. The licensee stated that these new requirements in TS 3.6.D areconsistent with NUREG-1431. The NRC staff found this proposed TS revision consistent withNUREG-1431, and, therefore, acceptable. 3.7Proposed Replacement of TS 3.6.EThe licensee proposed to renumber the current TS 3.6.E as TS 3.6.H, and replace TS 3.6.Ewith the following paragraph. E.With the turbine driven pump inoperable on the affected unit and withReactor Coolant System temperature and pressure greater than 350 °F and 450 psig, respectively, immediately following REFUELING SHUTDOWN and prior to REACTOR CRITICAL, restore the inoperable pump to OPERABLE status within 7 days or be less than 350 °F and 450 psig within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.The licensee's new TS 3.6.E includes a 7-day AOT for turbine-driven AFW pump inoperabilityon the affected unit following a refueling outage and prior to reactor criticality. The licensee stated that these new required actions are consistent with NUREG-1431. The licensee furtherstated that, due to the Surry AFW system configuration, the 7-day AOT for an inoperable steamsupply to the turbine-driven AFW pump, as provided in NUREG-1431, was not includedbecause it is not applicable. However, the more conservative 72-hour AOT was applied for the turbine-driven AFW pump when in the steam supply for this pump is lost. The NRC staff f oundthis proposed TS revision consistent with NUREG-1431, and, therefore, acceptable.3.8Proposed Replacement of TS 3.6.F TS 3.6.F currently states:F.With one auxiliary feedwater pump inoperable, restore at least threeauxiliary feedwater pumps (two motor driven feedwater pumps and onesteam driven feedwater pump) to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in HOT SHUTDOWN within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.The licensee proposed to replace TS 3.6.F with the following information:F.The following actions shall be taken when one or more auxiliaryfeedwater pumps are inoperable on the affected unit for reasons other than those addressed in Specification 3.6.E:1.With one auxiliary feedwater pump inoperable, restore theinoperable pump to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in HOT SHUTDOWN within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and be less than 350 °F and 450 psig within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.2.With two auxiliary feedwater pumps inoperable, be in HOTSHUTDOWN within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and be less than 350 °F and 450 psig within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.3.With three auxiliary feedwater pumps inoperable, immediatelyinitiate action to restore one inoperable pump to OPERABLE status. Specification 3.0.1 and all other required actions directing mode changes are suspended until one inoperable pump isrestored to OPERABLE status.The licensee replaced the current TS 3.6.F to eliminate inconsistency between AFW pumprequirements and to be consistent with NUREG-1431. The licensee replaced the current TS3.6.F AFW required actions with new required actions to be taken when one or more AFW pumps are inoperable (e.g., 72-hour AOT for 1 inoperable AFW pump, etc.) on the affected unit. The NRC staff found the proposed TS revisions consistent with NUREG-1431, and,therefore, acceptable. 3.9Proposed Replacement of TS 3.6.GThe licensee proposed to renumber the current TS 3.6.G as 3.6.I, and replace TS 3.6.G withthe following information. G.The following actions shall be taken with inoperability of a com ponent orinstrumentation other than the flow instrumentation in one or bothredundant auxiliary feedwater flowpaths required by Specification 3.6.C.3on the affected unit: (See Specification 3.7 and TS Table 3.7-6 for auxiliary feedwater flow instrumentation requirements.)1.With component or instrumentation inoperability in one redundantflowpath, restore the inoperable component or instrumentation to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in HOT SHUTDOWN within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and be less than 350 °F and 450 psig within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.2.With component or instrumentation inoperability affecting bothredundant flowpaths, immediately initiate action to restore the inoperable component or instrumentation in one flowpath to OPERABLE status. Specification 3.0.1 and all other required actions directing mode changes are suspended until the inoperable component or instrumentation in one flowpath is restored to OPERABLE status.The licensee replaced TS 3.6.G to be consistent with NUREG-1431. The licensee replaced thecurrent TS 3.6.G with new AFW flowpath/instrumentation required actions to be taken when one or both redundant flowpaths are inoperable (e.g., 72-hour AOT for 1 inoperable flowpath) on the affected unit. The NRC staff found these proposed TS revisions consistent withNUREG-1431, and, therefore, acceptable.3.10Proposed Changes to Current TS 3.6.G (New 3.6.I), TS 3.6.G.1, TS 3.6.G.2, AndTS 3.6.G.3 3.10.1 TS 3.6.G currently states:G.The requirements of TSs 3.6.B and 3.6.D above concerning the oppositeunit's auxiliary feedwater pumps; associated piping, valves, and control board indication; and the protected condensate storage tank may bemodified to allow the following components to be inoperable, provided immediate attention is directed to making repairs.The licensee proposed to relocate the following phrase in parentheses from the current TS 3.6.D to the current TS 3.6.G, and renumber TS 3.6.G as TS 3.6.I:(automatic initiation instrumentation associated with the opposite unit's auxiliaryfeedwater pumps need not be OPERABLE)In addition, the licensee proposed to revise the new 3.6.I to read as follows:I.The requirements of Specification 3.6.C.4 above concerning the oppositeunit's auxiliary feedwater pumps; the associated redundant flowpaths,including piping, headers, valves, and control board indication; the cross-connect piping from the opposite unit; and the protected condensate storage tank may be modified to allow the following components to be inoperable, provided immediate attention is directed to making repairs.
Automatic initiation instrumentation associated with the opposite unit's auxiliary feedwater pumps need not be OPERABLE.The licensee made several changes to the new TS 3.6.I. First, the licensee relocated thecurrent TS 3.6.D requirement that
<automatic initiation instrumentation associated with theopposite unit's auxiliary feedwater pumps need not be operable' to the new TS 3.6.I. Next, thelicensee made changes to the AFW cross-connect flowpath terminology in order to be consistent with the flowpath terminology changes that were made to the new TS 3.6.C.3. Finally, the licensee included the required actions for the opposite unit's AFW cross-connect pump and flowpath whenever components described in TS 3.6.I.1 through TS 3.6.I.3 areinoperable. The AFW systems for Surry 1 and 2 are cross-connected to provide additionalredundancy in case a single event, such as fire or a high energy line break in the main steam valve house, disables the AFW system for one unit. Therefore, the NRC staff determi ned thatthe licensee's proposed changes properly reflect the design capability and are consistent withthe intent of GDCs 34 and 44. As such, the licensee's proposed changes are acceptable. 3.10.2TS 3.6.G.1 currently states:1.One train of the opposite unit's piping, valves, and control boardindications or two of the opposite units's auxiliary feedwater pumps maybe inoperable for a period of not to exceed 14 days.The licensee proposed to renumber TS 3.6.G.1 as TS 3.6.I.1 and revise the TS as follows:1.One of the opposite unit's flowpaths or two of the opposite unit's auxiliaryfeedwater pumps may be inoperable for a period not to exceed 14 days.Corresponding to TS 3.6.I above, the licensee revised the renumbered TS 3.6.I.1 to include oneof the opposite unit's flowpaths that may be inoperable for a period not to exceed 14 days. In addition, the licensee made changes to the AFW cross-connect flowpath terminology in order to be consistent with the flowpath terminology changes that were made to the new TS 3.6.C.3. The flowpaths at Surry 1 and 2 include piping, headers, valves, and control board indications. The AFW systems for Surry 1 and 2 are cross-connected to provide additional redundancy incase a single event, such as fire or a high energy line break in the main steam valve house, disables the AFW system for one unit. Therefore, the NRC staff determined that the licensee'sproposed changes properly reflect the design capability that is consistent with the intent ofGDCs 34 and 44, and the licensee's proposed changes are acceptable.3.10.3TS 3.6.G.2 currently states:2.Both trains of the opposite unit's piping, valves, and control boardindications; the opposite unit's protected condensate storage tank; the cross-connect piping from the opposite unit; or three of the opposite unit's auxiliary feedwater pumps may be inoperable for a period not to exceed72 hours.The licensee proposed to renumber TS 3.6.G.2 as TS 3.6.I.2 and revised as follows:2.Both of the opposite unit's flowpaths; the opposite unit's protectedcondensate storage tank; the cross-connect piping from the opposite unit; or three of the opposite unit's auxiliary feedwater pumps may beinoperable for a period not to exceed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.Corresponding to TS 3.6.I above, the licensee revised the renumbered TS 3.6.I.2 to includeboth of the opposite unit's flowpaths that may be inoperable for a period not to exceed 72hours. In addition, the licensee made changes to the AFW cross-connect flowpath terminology in order to be consistent with the flowpath terminology changes that were made to the newTS 3.6.C.3. The flowpaths at Surry 1 and 2 include piping, headers, valves, and control boardindications. The AFW systems for Surry 1 and 2 are cross-connected to provide additionalredundancy in case a single event, such as fire or a high energy line break in the main steam valve house, disables the AFW system for one unit. Therefore, the NRC staff determi ned thatthe licensee's proposed changes properly reflect the design capability and are consistent withthe intent of GDCs 34 and 44. As such, the licensee's proposed changes are acceptable.3.10.4 The licensee proposed to renumber TS 3.6.G.3 as TS 3.6.I.3, change
<flow path' to
<flowpath', and change
<TS 3.6.B.4.c' to
<TS 3.6.C.4.c.' The NRC staff determined that thesechanges are editorial, and, therefore, acceptable.3.10.5 The end statement in TS 3.6.G currently states:If the above requirements are not met, be in HOT SHUTDOWN within the next 6hours and in COLD SHUTDOWN within the next 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.The licensee proposed to renumber the last statement of TS 3.6.G as TS 3.6.I and revise theTS as follows:If the above requirements are not met, be in HOT SHUTDOWN within the next 6hours and be less than 350 °F and 450 psig within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. For the AFW required actions in the renumbered TS 3.6.I, the licensee revised the end state ofhot shutdown to more appropriately reflect the plant condition where the AFW system is nolonger required to be operable. Given the licensee's revision of the end statement to more appropriately include the plant condition of less than 350 °F and 450 psig (where an operable AFW system is not required) and the fact that the licensee's proposed changes properly reflectthe design capability that is consistent with the intent of GDCs 34 and 44, the NRC staff f oundthe licensee's proposed changes acceptable.3.11Proposed Changes to Current TS 3.6.H The licensee proposed to renumber TS 3.6.H as TS 3.6.J, replace
<TS 3.6.B.2' with
<TS3.6.C.2', and replace the term
<steam generator' with
<feedwater.' The NRC staff determined that these changes are editorial and have no impact upon thetechnical aspects of the items that were removed or relocated. Therefore, the NRC staff f oundthese proposed changes acceptable.3.12Proposed Changes to TS 4.8 3.12.1 The licensee proposed to change the spelling of <flow path' to
<flowpath' in TS 4.8.A.1.,TS 4.8.A.2., and TS 4.8.A.5.b. The NRC staff has determined that these changes are editorial. Therefore, the NRC staff found these proposed changes acceptable.3.12.2 TS 4.8.A.3.a currently states:a.Verify that the auxiliary feedwater pumps perform satisfactorily whentested in accordance with the Inservice Testing Program. The provisions of TS 4.0.4 are not applicable for the turbine driven pump.The licensee proposed to revise TS 4.8.A.3.a as follows:a.Verify that the auxiliary feedwater pumps perform satisfactorily whentested in accordance with the Inservice Testing Program. The provisions of Specification 4.0.4 are not applicable for the turbine driven pump. Note that the developed head test of the turbine driven pump is required to be performed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after reaching HOT SHUTDOWN.The licensee revised this TS 4.8 surveillance to be consistent with NUREG-1431. A note wasadded to TS 4.8.A.3.a to qualify that the developed head test of the turbine-driven AFW pumpis required to be performed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after reaching hot shutdown. The NRC staff f oundthis TS revision consistent with NUREG-1431, and, therefore, acceptable. 3.12.3 TSs 4.8.A.4a and 4.8.A.4b currently state:4a.Within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> prior to Reactor Coolant System temperature andpressure exceeding 350 °F and 450 psig, respectively, the motor driven auxiliary feedwater pumps shall be flow tested from the 110,000 gallonabove-ground Emergency Condensate Storage Tank to the steam generators. 4b.Within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after achieving reactor criticality, the steam turbine drivenauxiliary feedwater pump shall be flow tested from the 110,000 gallonabove-ground Emergency Condensate Storage Tank to the steam generators. The provisions of Specification 4.0.4 are not applicable.The licensee proposed to replace TSs 4.8.A.4a and 4.8.A.4b with TS 4.8.A.4. TS 4.8.A.4 isrevised to read as follows:4.Whenever the unit's Reactor Coolant System temperature and pressurehave been less than 350 °F and 450 psig, respectively, for a period greater than 30 days, prior to Reactor Coolant System temperature and pressure exceeding 350 °F and 450 psig, respectively, verify proper alignment of the required auxiliary feedwater flowpaths by verifying flowfrom the 110,000 gallon above-ground Emergency Condensate Storage Tank to the steam generators from each of the auxiliary feedwaterpumps.The licensee revised these TS surveillances to be consistent with NUREG-1431. The licenseereplaced the current TSs 4.8.A.4a and 4.8.A.4b flow test requirements with a verification ofproper alignment of the AFW flowpaths prior to exceeding 350 °F and 450 psig, whenever the RCS conditions have been less than 350 °F and 450 psig for a period greater than 30 days.
The NRC staff found these TS revisions consistent with NUREG-1431, and, therefore,acceptable.3.12.4 New TS 4.8.A.6 The licensee proposed to create TS 4.8.A.6 to provide new AFW automatic valve and pumpsurveillances. The new TS 4.8.A.6 will read as follows:6.On an 18-month frequency:a.Verify each auxiliary feedwater automatic valve that is not locked,sealed, or otherwise secured in position, actuates to the correct position on an actual or simulated actuation signal.b.Verify each auxiliary feedwater pump starts automatically on anactual or simulated actuation signal. Note that this surveillance isrequired to be performed for the turbine driven pump within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after reaching HOT SHUTDOWN.The licensee added these TS surveillances to be consistent with NUREG-1431. These18-month TS surveillances provide for verification of the correct position for the AFW automatic valve actuation and for the verification of AFW pump auto-start. The NRC staff found theseproposed revisions consistent with NUREG-1431, and, therefore, acceptable. 3.12.5 TS 4.8.B currently states:B.Acceptance Criteria The pump and valve tests, except the system flow test, shall beconsidered satisfactory if they meet the Inservice Testing Program acceptance criteria.The system flow tests during unit startup from COLD SHUTDOWN orREFUELING SHUTDOWN shall be considered satisfactory if the control board indication demonstrates that flow paths exist to each steam generator.The licensee proposed to revise TS 4.8.B as follows:B.Acceptance CriteriaThe pump and valve tests shall be considered satisfactory if they meetthe Inservice Testing Program acceptance criteria.The flowpath alignment tests during unit startup from REFUELING,COLD, or INTERMEDIATE SHUTDOWN shall be considered satisfactory if the control board indication demonstrates that flowpaths exist to each steam generator.The licensee revised this surveillance to be consistent with NUREG-1431. The licensee revisedTS 4.8.B acceptance criteria to reflect the deletion of flow test requirements and the replacement with flowpath alignment requirements in TS 4.8.A.4. Intermediate shutdown isadded since RCS conditions less than 350 °F and 450 psig partially encompass the intermediate shutdown operating condition, defined in TS 1.0.C.3. The NRC staff found theseTS revisions consistent with NUREG-1431, and, therefore, acceptable. 3.13Licensee's Proposed Basis ChangesThe licensee revised the basis for TS 3.6 and TS 4.8 to describe the AFW systemconfiguration, to discuss the AFW system design basis and accident analysis requirements,and add a discussion on AFW pump operability considerations. Furthermore, the licenseemade changes that were editorial, corresponded to the TS revisions, and updated the references to the Updated Final Safety Analysis for Surry. The NRC staff found theseproposed revisions of the TS 3.6 and TS 4.8 bases acceptable.
3.14ConclusionBased on its review of the licensee's submittal dated March 8, 2005, the NRC staff concl udedthat the proposed TS revisions properly reflect the design capability that is consistent with theintent of GDCs 34 and 44, and are consistent with NUREG-1431. As such, the NRC staff hasdetermined that the licensee's proposed amendments are acceptable with regard to thefollowing:oElimination of TS 3.6 inconsistency between the current AFW pump operabilityrequirements and required actions oAddition of TS 3.6 flowpath AOT and required actionsoRevision of TS 3.6 operability requirements and required actions and TS 4.8surveillances for AFW system.
