PUBLIC NOTICE NRC STAFF CONSIDERING LICENSE AMENDMENT REQUEST g FOR MCGUIRE NUCLEAR STATION, UNITS 1 AND 2 l The Nuclear Regulatory Commission has received an application dated September 13, 1999, from Duke Energy Corporation (the licensee) for an exigent amendment to the operating licenses for the McGuire Nuclear Station, Units 1 and 2, located in Mecklenberg County, North Carolina.

I If approved, the amendments would allow up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to restore the Control Room Pressure Boundary (CRPB) to operable status when two control room area ventilation system l (CRAVS) trains are inoperable due to an inoperable CRPB in MODES 1,2,3, and 4. In addition, a Limiting Condition for Operation note would be added to allow the CRPB to be opened intermittently under administrative control without affecting CRAVS operability. These changes would be effective upon issuance.

The licensee has evaluated the requested amendment against the standards in 10 CFR

  • 50.92, and the NRC staff has made a proposed determination that the requested amendment 1

involves no significant hazards considerations. Under the subject regulation, this means that the proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated, would not create the possibility of a new or different kind of ;

- <. l accident from any accident previously evaluated, or involve a significant reduction in a margin of l safety.  !

l The licensee's analysis is presented below:

1. Does the change involve a significant increase in the probability or consequences ,

of an accident previously evaluated? 1 i

l

s No. The Control Room Area Ventilation System and Control Room boundary are not assumed to be an initiator of any analyzed accident; they are provided to minimize doses to the control room operators during an accident. Therefore, these proposed changes have no impact on the probability 6ioccurrence of any previously analyzed accident.

The proposed changes also have no impact on offsite dose consequences. The control room ventilation system and control room boundary provide protection for control room personnel only and do not mitigate radiological effluents released offsite. With the l control room boundary inoperable and not pressurized, the accident analyses assume unfiltered air would enter the control room and operator doses would be significantly increased. Conservative accident analysis assumptions do not take credit for available compensatory measures to mitigate operator dose. Compensatory measures include the use of the alternate control room intake to select the intake with the lowest radioactivity level, filtration of outside air by an operable CRAVS train, and the availability of self-contained breathing apparatus.

Additionally, for cases where the control room boundary is opened under administrative control, appropriate administrative measures would be required by the proposed TS

[ Technical Specifications) to ensure the boundary can be rapidly restored. Based on the compensatory measures available to the control room operator to minimize dose, the administrative controls required to rapidly restore an opened boundary, and considering the low probability of an event occurring in this short time period, the consequences are not considered to be significantly increased. Operators maintain the ability to mitigate a design basis event.

2. Does the change create the possibi!ity of a new or different kind of accident from any accident previously evaluated?

No. No changes are being made to actual plant hardware which will result in any new accident causal mechanisms. Also, no changes are being made to the way in which the plant is being operated, Therefore, no new accident causal mechanisms will be generated.

3. Does this change involve a significant reduction in a margin of safety?

No. Margin of safety is related to the ability of the fission product barriers to perform their design functions during and following accident conditions. These barriers include the fuel cladding, the reactor coolant system, and the containment system. The performance of these barriers will not be degraded by the proposed changes. The Control Room Ventilation System and control room boundary provide a protected environment for the control room operators during analyzed events. The proposed change would allow the boundary to be degraded for a limited period of time. However, administrative controls would be in place to rapidly restore an opened boundary and existing compensatory measures (e.g., breathing apparatus) would be implemented to minimize operator dose. Therefore, it is expected that operators would maintain the l ability to mitigate design basis events and none of the fission product barriers would be l

1 affected by this change. Therefore, the proposed change is not considered to result in a significant reduction in a margin of safety.

If the proposed determination that the requested license amendment involves no significant haza.ds consideration becomes final, the NRC will issue the amendment without first offering an opportunity for a public hearing. An opportunity for a public hearing will be published in the Federal Reaister at a later date and any hearing request will not delay the effective date of the amendment. l 1

l If the NRC staff decides in its final determination that the amendment does involve a l significant hazards consideration, a notice of opportunity for a prior hearing will be l published in the Federal Reaister and, if a hearing is granted, it will be held before the amendment is issued.

Comments on the proposed determination oi no significant hazards consideration may be (1) telephoned to Richard Emch, Section Chief, by collect call to 1-415-1485 or by facsimile to 1-301-415-2102, (2) e-maifed to lNTERNET:RLE@NRC. GOV. or (3) submitted in writing to Chief, Rules and Directives Review Branch, Division of Administrative Services, Office of Administration, U. S. Nuclear Regulatory Commission, Washington, DC 20555-0001. All written comments received by close of business on September 17,1999, and all telephoned or e-mailed comments received by 4:15 p.m., September 17,1999, will be considered in reaching a final determination.

A copy of the licensee's application may be examined at the NRC's Local Public Document Room located at the J. Murrey Atkins Library, University of North Carolina at l Charlotte,9201 University City Boulevard, Charlotte, NC, and the NRC's Public Document Room, the Gelman Building,2120 L Street, NW, Washington, DC 20555.
