This analysis shall beprovided to the NRC within one year after NRCapproval of the March 5, 2012 McGuireMeasurement Uncertainty Recapture (MUR)License Amendment Request.Renewed License No. NPF-17Amendment No. 249IB-3 APPENDIX CANTITRUST CONDITIONS Pursuant to an Order by the Atomic Safety and Licensing Board, dated April 23, 1975, theNuclear Regulatory Commission incorporates in Operating License NPF-17 the following antitrust conditions:

a. The licensee makes the commitments contained herein, recognizing that bulkpower supply arrangements between neighboring entities normally tend to servethe public interest.

In addition, where there are net benefits to all participants such arrangements also serve the best interests of each of the participants.

Among the benefits of such transactions are increased electric system reliability, a reduction in the cost of electric power, and minimization of the environmental effects of the production and sale of electricity.

Any particular bulk power supply transaction may afford greater benefits to oneparticipant than to another.

The benefits realized by a small system may beproportionately greater than those realized by a larger system. The relativebenefits to be derived by the parties from a proposed transaction, however,should not be controlling upon a decision with respect to the desirability ofparticipating in the transaction.

Accordingly, the licensee will enter intoproposed bulk power transactions of the types hereinafter described which, onbalance, provide net benefits to the licensee.

There are net benefits in atransaction if the licensee recovers the cost of the transaction (as defined insubparagraph (1)(d) hereof) and there is no demonstrable net detriment to thelicensee arising from the transaction.

(1) As used herein:(a) "Bulk Power" means electric power and any attendant energy,supplied or made available at transmission or sub-transmission voltage by one electric system to another.(b) "Neighboring Entity" means a private or public corporation, agovernmental agency or authority, a municipality, a cooperative, or alawful association of any of the foregoing owning or operating, orproposing to own or operate, facilities for the generation andtransmission of electricity which meets each of the following criteria:

(1) its existing or proposed facilities are economically and technically feasible of interconnection with those of the licensee and (2) with theexception of municipalities, cooperatives, governmental agencies orauthorities, and associations, it is, or upon commencement ofoperations will be, a public utility and subject to regulation with respectto rates and service under the laws of North Carolina or SouthCarolina or under the Federal Power Act; provided,

however, that asto associations, each member of such association is either a publicutility as discussed in this clause (2) orC-1 a municipality, a cooperative or .a governmental agency or authority.

(c) Where the phrase "neighboring entity" is intended to include entitiesengaging or proposing to engage only in the distribution of electricity, this is indicated by adding the phrase "including distribution systems."

(d) "Cost means any appropriate operating and maintenance

expenses, together with all other costs, including a reasonable return on thelicensee's investment, which are reasonably allocable to a transaction.

However, no value shall be included for loss of revenue due to theloss of any wholesale or retail customer as a result of any transaction hereafter described.

(2) (a) The licensee will interconnect and coordinate reserves by means ofthe sale and exchange of emergency and scheduled maintenance bulk power with any neighboring entity(ies),

when there are netbenefits to each party, on terms that will provide for all of thelicensee's properly assignable costs as may be determined by theFederal Energy Regulatory Commission and consistent with such costassignment will allow the other party the fullest possible benefits ofsuch coordination.

(b) Emergency service and/or scheduled maintenance service to beprovided by each party will be furnished to the fullest extent available from the supplying party and desired by the party in need. Thelicensee and each party will provide to the other emergency serviceand/or scheduled maintenance service if and when available from itsown generation and, in accordance with recognized industry

practice, from generation of other to the extent it can do so without impairing service to its customers, including other electric systems to whom ithas firm commitments.

(c) Each party to a reserve coordination arrangement will establish itsown reserve criteria, but in no event shall the minimum installed reserve on each system be less than 15%, calculated as a percentage of estimated peak load responsibility.

Either party, if it has, or hasfirmly planned, installed reserves in excess of the amount called for byits own reserve criterion, will offer any such excess as may in fact beavailable at the time for which it is sought and for such period as theselling party shall determine for purchase in accordance withreasonable industry practice by the other party to meet such otherparty's own reserve requirements.

The parties will provide suchamounts of spinning reserve as may be adequate to avoid theimposition of unreasonable demands on the other part(ies) in meetingthe normal contingencies of operating its (their) system(s).

However,in no circumstances shall such spinning reserve requirement exceedthe installed reserve requirement.

(d) Interconnections will nof'6e limited to low voltages when highervoltages areC-2 available from the licensee's installed facilities in the area whereinterconnection is desired and when the proposed arrangement isfound to be technically and economically feasible.

(e) Interconnection and reserve coordination agreements will not embodyprovisions which impose limitations upon the use or resale of powerand energy sold or exchanged pursuant to the agreement.

Further,such arrangements will not prohibit the participants from entering intoother interconnection and coordination arrangements, but may includeappropriate provisions to assure that (i) the licensee receivesadequate notice of such additional interconnection or coordination, (ii)the parties will jointly consider and agree upon such measures, if any,as are reasonably necessary to protect the reliability of theinterconnected systems and to prevent undue burdens from beingimposed on any system, and (iii) the licensee will be fullycompensated for its costs. Reasonable industry practice asdeveloped in the area from time to time will satisfy this provision.

(3) The licensee currently has on file, and may hereafter file, with the FederalEnergy Regulatory Commission contracts with neighboring entity(ies) providing for the sale and exchange of short-term power and energy, limitedterm power and energy, economy energy, non- displacement energy, andemergency capacity and energy. The Licensee will enter into contracts providing for the same or for like transactions with any neighboring entity onterms which enable the licensee to recover the full costs allocable to suchtransaction.

(4) The licensee currently sells capacity and energy in bulk on a fullrequirements basis to several entities engaging in the distribution of electricpower at retail. In addition, the licensee supplies electricity directly toultimate users in a number of municipalities.

Should any such entity(ies) ormunicipality(ies) desire to become a neighboring entity as defined insubparagraph (1)(b) hereof (either alone or through combination withothers),

the licensee will assist in facilitating the necessary transition throughthe sale of partial requirements firm power and energy to the extent that,except for such transition, the licensee would otherwise be supplying firmpower and energy. The provision of such firm partial requirements serviceshall be under such rates, terms and conditions as shall be found by theFederal Energy Regulatory Commission to provide for the recovery of thelicensee's cost. The licensee will sell capacity and energy in bulk on a fullrequirements basis to any municipality currently served by the licensee whensuch municipality lawfully engages in the distribution of electric power atretail.(5) (a) The licensee will facilitate the exchange of electric power in bulk inwholesale transactions over its transmission facilities (1) between oramong two or more neighboring entities including distribution systems with which it is interconnected or may be interconnected inthe future, and (2) between any such entity(ies) and any other electricsystem engaging in bulk power supply between whose facilities thelicensee's transmission C-3 lines and other transmission lines would form a continuous electric path,provided that permission to utilize such other transmission lines has beenobtained.

Such transaction shall be undertaken provided that theparticular transaction reasonably can be accommodated by the licensee's transmission system from a functional and technical standpoint and doesnot constitute the wheeling of power to a retail customer.

Suchtransmission shall be on terms that fully compensate the licensee for itscost. Any entity(ies) requesting such transmission arrangements shallgive reasonable notice of its (their) schedule and requirements.

(b) The licensee will include in its planning and construction programsufficient transmission capacity as required for the transactions referredto in subparagraph (a) of this paragraph, provided that (1) the neighboring entity(ies) gives the licensee sufficient advance notice as may benecessary reasonably to accommodate its (their) requirements from afunctional and technical standpoint and (2) that such entity(ies) fullycompensate the licensee for its cost. In carrying out this subparagraph (b), however, the licensee shall not be required to construct or addtransmission facilities which (a) will be of no demonstrable present orfuture benefit to the licensee, or (b) which could be constructed by therequesting entity(ies) without duplicating any portion of the licensee's existing transmission lines, or (c) which would jeopardize the licensee's ability to finance or construct on reasonable terms facilities needed tomeet its own anticipated system requirements.

Where regulatory orenvironmental approvals are required for the construction or addition oftransmission facilities needed for the transactions referred to insubparagraph (a) of this paragraph it shall be the responsibility of theentity(ies) seeking the transaction to participate in obtaining suchapprovals, including sharing in the cost thereof.(6) To increase the possibility of achieving greater reliability and economy ofelectric generation and transmission facilities, the licensee will discuss loadprojections and system development plans with any neighboring entity(ies).

(7) When the licensee's plans for future nuclear generating units (for whichapplication will hereafter be made to the Nuclear Regulatory commission) have reached the stage of serious planning, but before firm decisions havebeen made as to the size and desired completion date of the proposednuclear units, the licensee will notify all neighboring entities including distribution systems with peak loads smaller than the licensee's that thelicensee plans to construct such nuclear units. Neither the timing nor theinformation provided need be such as to jeopardize obtaining the requiredsite at the lowest possible cost.The foregoing commitments shall be implemented in a manner consistent with the provisions of the Federal Power Act and all other lawful local, stateand Federal regulation and authority.

Nothing in these commitments isintended to determine in advance the resolution of issues which are properlyraised at the Federal Energy Regulatory Commission concerning suchcommitments, C-4 including allocation of costs or the rates to be charged.

The licensee willnegotiate (including the execution of a contingent statement of intent) withrespect to the foregoing commitments with any neighboring entity including distribution systems where applicable engaging in or proposing to engage inbulk power supply transactions, but the licensee shall not be required toenter into any final arrangement prior to resolution of any substantial questions as to the lawful authority of an entity to engage in the transactions.

In addition, the licensee shall not be obligated to enter into a given bulkpower supply transaction if: (1) to do so would violate, or incapacitate it fromperforming, and existing lawful contracts it has with a third party; (2) there iscontemporaneously available to it a competing or alternate arrangement which affords it greater benefits which would be mutually exclusive of sucharrangement; (3) to do so would adversely affect its system operations or thereliability of power supply to its customers, or (4) if to do so would jeopardize the licensee's ability to finance or construct on reasonable terms facilities needed to meet its own anticipated system requirements.

The MSSVs also provide protection againstoverpressurizing the reactor coolant pressure boundary (RCPB) byproviding a heat sink for the removal of energy from the Reactor CoolantSystem (RCS) if the preferred heat sink, provided by the Condenser andCirculating Water System, is not available.

Five MSSVs are located on each main steam header, outsidecontainment, upstream of the main steam isolation valves, as described in the UFSAR, Section 10.3.1 (Ref. 1). The MSSV capacity criteria is110% of rated steam flow at 110% of the steam generator designpressure.

This meets the requirements of the ASME Code,Section III(Ref. 2). The MSSV design includes staggered setpoints, according toTable 3.7.1-2 in the accompanying LCO, so that only the needed valveswill actuate.

Each valve is orificed to a size of either 12.174 or 16.0square inches. Staggered setpoints reduce the potential for valvechattering that is due to steam pressure insufficient to fully open all valvesfollowing a turbine reactor trip.APPLICABLE SAFETY ANALYSESThe design basis for the MSSVs comes from Reference 2 and itspurpose is to limit the secondary system pressure to 5 110% of designpressure when passing 100% of design steam flow. This design basis issufficient to cope with any anticipated operational occurrence (AOO) oraccident considered in the Design Basis Accident (DBA) and transient analysis.

The events that challenge the relieving capacity of the MSSVs, and thusRCS pressure, are those characterized as decreased heat removalevents, which are presented in the UFSAR, Section 15.2 (Ref. 3). Ofthese, the full power turbine trip without steam dump is the limiting AOO.The transient response for turbine trip without a direct reactor trippresents no hazard to the integrity of the RCS or the Main Steam System.The reactor is tripped on high pressurizer pressure in the peak primarypressure case. In this case, the pressurizer safety valves open, and RCSpressure remains below 110% of the design value. The MSSVs alsoopen to limit the secondary steam pressure.

McGuire Units 1 and 2B 3.7. 1-1Revision No. 129 MSSVsB 3.7.1BASESAPPLICABLE SAFETY ANALYSES (continued)

For the peak secondary pressure case, the reactor is tripped onovertemperature AT. Pressurizer relief valves and MSSVs areactivated and prevent overpressurization in the primary andsecondary systems.The MSSVs satisfy Criterion 3 of 10 CFR 50.36 (Ref. 4).LCO The accident analysis assumes five MSSVs per steam generator to provide overpressure protection for design basis transients occurring at 3479 MWt. An MSSV will be considered inoperable ifit fails to open on demand. The LCO requires that five MSSVs beOPERABLE in compliance with Reference 2, even though this isnot a requirement of the DBA analysis.

This is because operation with less than the full number of MSSVs requires limitations onallowable THERMAL POWER (to meet ASME Coderequirements).

These limitations are according to Table 3.7.1-1 inthe accompanying LCO, and Required Action A.1 and A.2.The OPERABILITY of the MSSVs is defined as the ability to openwithin the setpoint tolerances, relieve steam generator overpressure, and reseat when pressure has been reduced.

TheOPERABILITY of the MSSVs is determined by periodicsurveillance testing in accordance with the Inservice TestingProgram.The lift settings, according to Table 3.7.1-2 in the accompanying LCO, correspond to ambient conditions of the valve at nominaloperating temperature and pressure.

This LCO provides assurance that the MSSVs will perform theirdesigned safety functions to mitigate the consequences ofaccidents that could result in a challenge to the RCPB.APPLICABILITY In MODE 1, the number of MSSVs per steam generator required to beOPERABLE must be according to Table 3.7.1-1 in the accompanying LCO. In MODES 2 and 3, only two MSSVs per steam generator arerequired to be OPERABLE.

In MODES 4 and 5, there are no credible transients requiring the MSSVs.The steam generators are not normally used for heat removal inMODES 5 and 6, and thus cannot be overpressurized; there is norequirement for the MSSVs to be OPERABLE in these MODES.McGuire Units I and 2B 3.7.1-2Revision No. 129 MSSVsB 3.7.1BASESACTIONS The ACTIONS table is modified by a Note indicating that separateCondition entry is allowed for each MSSV.A.1 and A.2With one or more MSSVs inoperable, reduce power so that theavailable MSSV relieving capacity meets Reference 2 requirements for the applicable THERMAL POWER.Operation with less than all five MSSVs OPERABLE for each steamgenerator is permissible, if THERMAL POWER is proportionally limited to the relief capacity of the remaining MSSVs. This isaccomplished by restricting THERMAL POWER so that the energytransfer to the most limiting steam generator is not greater than theavailable relief capacity in that steam generator.

For example, if oneMSSV is inoperable in one steam generator, the relief capacity ofthat steam generator is reduced by approximately 20%. To offsetthis reduction in relief capacity, energy transfer to that steamgenerator must be similarly reduced.

This is accomplished byreducing THERMAL POWER by the necessary amount toconservatively limit the energy transfer to all steam generators, consistent with the relief capacity of the most limiting steamgenerator.

The maximum power level specified for the power range neutronflux high trip setpoint with inoperable MSSVs must ensure thatpower is limited to less than the heat removal capacity of theremaining OPERABLE MSSVs. The reduced high flux trip setpointalso ensures that the reactor trip occurs early enough in the loss ofload/turbine trip event to limit primary to secondary heat transferand preclude overpressurization of the primary and secondary systems.

To calculate this power level, the governing equation isthe relationship q = m Ah, where q is the heat input from theprimary side, m is the steam flow rate and Ah is the heat ofvaporization at the steam relief pressure (assuming no subcooled feedwater).

The algorithm use is consistent with therecommendations of the Westinghouse Nuclear Safety AdvisoryLetter, NSAL-94-001, dated January 20, 1994 (Ref. 6).Additionally, the calculated values are reduced by 9% to accountfor instrument and channel uncertainties.

The adjustment of the trip setpoints is a sensitive operation that may inadvertently trip the Reactor Protection System.McGuire Units 1 and 2B 3.7.1-3Revision No. 129 MSSVsB 3.7.1BASESACTIONS (continued)

B.1 and B.2If the MSSVs cannot be restored to OPERABLE status within theassociated Completion Time, or if one or more steam generators haveless than two MSSVs OPERABLE, the unit must be placed in aMODE in which the LCO does not apply.

The allowed Completion Times arereasonable, based on operating experience, to reach the required unitconditions from full power conditions in an orderly manner and withoutchallenging unit systems.SURVEILLANCE SR 3.7.1.1REQUIREMENTS This SR verifies the OPERABILITY of the MSSVs by theverification of each MSSV lift setpoint in accordance with theInservice Testing Program.

The ASME OM Code (Ref. 5) requiresthat safety and relief valve tests be performed.

According toReference 5, the following tests are required:

a. Visual examination;

b. Seat tightness determination;

c. Setpoint pressure determination (lift setting);

d. Compliance with seat tightness criteria; ande. Verification of the balancing device integrity on balanced valves.The ASME Standard requires that all valves be tested every5 years, and a minimum of 20% of the valves be tested every24 months. The ASME OM Code specifies the activities andfrequencies necessary to satisfy the requirements.

Table 3.7.1-2allows a + 3% setpoint tolerance for OPERABILITY;

however, thevalves are reset to + 1% during the Surveillance to allow for drift.This SR is modified by a Note that allows entry into and operation inMODE 3 prior to performing the SR. The MSSVs may be eitherbench tested or tested in situ at hot conditions using an assist deviceto simulate lift pressure.

If the MSSVs are not tested at hotconditions, the lift setting pressure shall be corrected to ambientconditions of the valve at operating temperature and pressure.
