UNITED STATES NUCLEAR REGULATORY COMISSION 1

DOCKET NOS. 50-369 AND 50-370
}
NOTICE OF CONSIDERATION OF ISSUANCE OF AMEN 0MENTS TO FACILITY OPERATING LICENSES. PROPOSED N0 SIGNIFICANT HAZARDS l
CONSIDERATION DETERMINATION. AND OPPORTUNITY FOR A HEARING
'j The U.S. Nuclear Regulatory Commission(the Commission) is considering,
' issuance of an amendment.to Facility Operating License Nos. NPF-9 and NPF 1 issued to Duke Power Company '(the licensee) for' operation of the McGuiret
]
~
. Nuclear. Station, Units 1 and 2, located in Mecklenburg County, North Carolina.
The proposed amendments would revise Technical-Specifications (TS) o 3.8.2.1 and-3.8.3.1 to allow installation of a modification to replace the l
l battery, main and tie breakers in response to an Electrical Distribution Systems Functional Inspection (EDSFI), conducted by the NRC in July 1991.
The
'l i
- existing breaker arrangement could result in a trip of both the battery and tain breakers if a fault occurs on one of the 125 VDC panelboards.
The 1
licensee committed to have these breakers replaced in 1995 with a better.
coordinated design to eliminate the concern.
Before issuance of the proposed license amendments, the Commission will i
have' made findings required by the Atomic Energy Act of 1954, as amended-(the Act) and the Commission's regulations.
The Commission has made a proposed determination that the amendment request involves no significant hazards consideration.
Under the Commission's i
regulations in 10 CFR 50.92, this means that operation of the facility in arenrdance with the proposed amendment would not (1) involve a significant W EoNe 9

increase in the probability'or consequences of an accident previously
=
-evaluated; or (2) create the possibility of 'a new or different kind of accident from any accident previously' evaluated; or.(3)' involve a significant i
- reduction in a margin of safety.
As required by 10 CFR 50.91(a), the licensee-has provided its analysis of the issue of no significant hazards consideration, which is presented belowi j
]
Criterion 1 Operation of the facility in accordance with the requested amendments l
will not involve a significant increase in the probability or.
i consequences of an accident previously evaluated.
At no point during this temporary modification.is power lost to the DC and AC panelboards'.
i A normal plant procedure is used to transfer power for the AC
{
panelboards back and forth between their inverters.and their alternate i
regulated AC power supplies (lKRP and 2KRP).
All inputs to the DC l
channel trouble alarm except those from the associated DC and AC 3
panelboard undervoltage relays will be blocked during the 112 hour-1 temporary modification period so that an undervoltage condition on any of the DC and AC panelboards during this period will be detected j
immediately.
Temporary cabling will satisfy cable separation criteria.
i Temporary cables and breakers meet all applicable safety class IE and seismic requirements.
There will be no degradation of distribution
't centers and panelboards as a result of temporary breakers being installed in them.
Criterion 2 Operation of the facility in accordance with the requested amendments 1
will not create the possibility of a new or different kind of accident from any accident previously evaluated.
The proposed TS changes will not create the possibility for an accident or malfunction of a different l
type that any previously evaluated.
No new failure modes are being created by the proposed TS changes.
'1 i
Criterion 3 j
Operation of the facility in accordance with the requested amendments will not involve a significant reduction in a margin of safety.
The proposed TS changes will not reduce the margin of safety as described in the bases for any Technical Specifications.
The bases for Tech.
l Specs. 3/4.8.2 and 3/4.8.3 (minimum specified independent and redundant i
A.C. and D.C. power sources and distribution systems to supple safety-related equipment for safe shutdown and mitigation / control of accident

i conditions) will not be impacted by these proposed TS changes.
The l
proposed TS changes will not reduce the margin of safety since the temporary cables and breakers meet all applicable safety class IE.and seismic. requirements.
The use of_ temporary cables and breakers to facilitate the de-energization of a vital bus and connection of its loads to its same, train vital bus for breaker replacement does not technically violate the applicable technical specifications since the intent of these technical specifications is to have uninterrupted power i
to the loads normally connected to this de-energized bus.
Instrumentation during the temporary modification period remains valid l
to immediately detect an undervoltage condition in the affected DC and AC panelboards.
Based on the preceding analyses, Duke Power concludes that the requested amendments do not involve a significant hazards consideration.
l The NRC staff has reviewed the licensee's analysis and, based on this review, it appears that the three standards of 10 CFR 50.92(c) are satisfied.
i Therefore, the NRC staff proposes to determine that the amendment request i
involves no significant hazards consideration.
The Commission is seeking public comments on this proposed determination.
Any comments received within 30 days after the date of 1
publication of this notice will be considered in making any final determination.
I Normally, the Commission will not issue the amendment until the expiration of the 30-day notice period.
However, should circumstances change during the notice period such that failure to act in a timely way would result, for example, in derating or shutdown of the facility, the Commission may issue the license amendment before the expiration of the 30-day notice period, provided that its final determination is that the amendment involves no significant hazards consideration.
The final determination will consider all public and State comments received.
Should the Commission take this
4; i
.e-
-l t
action, it will publish in the FEDERAL REGISTER a notice of issuance and i
prsvide for opportunity for a hearing after issuance.
Tha Commission expects that the need to take this action will occur very infrequently.
i Written comments may be submitted by mail'to the' Rules Review and Directives Branch, Division of Freedom of Information and Publications l
Services, Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555, and should cite the publication date and page number of this FEDERAL REGISTER notice.

If a hearing is requested, the Commission will make a final determination on the issue of no significant hazards consideration.
The final determination will serve to decide when the hearing is held.
If the final determination is that the amendment request involves no significant hazards consideration, the Commission may issue the amendment and
j
_7 make it immediately effective, notwithstanding the request for a hearing.
Any
' hearing held would take place after issuance of the amendment.
If the final determination is that the amendment request involves a significant hazards con' sideration, any hearing held would take place before the issuance of any amendment.
A request for a hearing or a petition for leave to intervene must be filed with the Secretary of the Comission, U.S. Nuclear Regulatory Commission, Washington, DC 20555, Attention:
