, NOTICE Of CONSIDERATION QF ISSVANCE Qf_ AMENDMENTS TO FACILITY OPERATING LICENSES. PROPOSED NO SIGNIFICANT HAZARD;
@]LG EERATION DETERMINATI.QN. AND OPPORTUNITY FOR A HEARING The U.S. Nuclear Regulatory Commission (the Commission) is considering is mance of an amendment to facility Operating License Nos. NPF-76 and NPF-80 issued to Houston Lighting & Power Company, et al., (the licensee) for operation of the South Texas Project, located in Matagorda County, Texas.
The original application dated August 30, 1991, was previously published in the FEDER/i E GISTER on October 16, 1991 (56 FR 51926).
That application was superseded in its entirety by application dated June 2,1992.
The oroposed amendments would chenge the technical specifications to reflect a change in the actuation logic which would accompany the replacement of the two original toxic gas monitoring channels with three state-of-the art toxic gas monitoring channels.
The actuation logic would be revised to provide a two-out-of-three (2/3) logic for a high toxic gas actuation signal and monitor failure actuation logic, as opposed to the current one-cut-of-two
-(1/2) and two-out-of-two (2/2) logic respectively.
In the June 2, 1992, L
submittal, the licensee requested approval of _ an interim technical specification in September 1992 followed by a final technical specification to l

3 be effective in february 1993.
This would allow adequate time for t,ardware and procedural cFanges to support installation of the third toxic gas monitoring channel during the Unit I re'.eling outage (fall 1992) and Unit 2 refueling outage (spring 1993).
Before i.,suance of the proposed license amendments, the Commission will have made findings required by the Atomic Energy Act of 1964, as amended (the Act) and the Commission's regulations.
The Commission has made a proposed determination that the amandment request involves no significant hazards consideration.
Under the Commission's-regulations in 10 CFR 50.92, this means that operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequeaces 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 reduction in a margin of safety. As required by 10 CFR 50.91(a), the licensee has providad its analysis of the issue of no significant hazards consideration, which is presented below:
(1) The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
The addition of a third channel of toxic gas monitoring would not i
increase the probability of a previously evaluated accident because the t'xic gas analyzers have no role in the initiation of an accident.
Consequences of a previously evaluated acciuent would not increase because a third monitor would provide additional redundancy,nd reliability to the current monitoring system.
Therefore, a more credibh
. xic gas monitoring system would be in

i 1 place, and the probability or consequences of an accident previously evaluated I
would not be significantly increased.
(2) The proposed change does not create the possibility of a new or l
different kind of accident from any previously evaluated.
The proposed change would not require the toxic gas monitoring system to perform any safety function for which it is not already designed or required i
to perform.
Adding a third analyzer to the monitoring system for each Unit would m vide additional redundancy in the detection of toxic gas release.
i l'
for these reasons, the proposed change would not create the possibility of a i
new or different kind of accident from any previously evaluated.
(3)
The proposed change does not involve a significant reduction in a margin of safety.
The decrease in probability of actuation when required for the_high toxic gas actuation signal and increase in probability of spurious actuation for the loss of power / malfunction actuation signal are slight and do not involve a significant reduction in a margin of safety.
[
The NRC staff has reviewed the licensee's analysis and, based on this -
i review, it appears that the three staadards of 10 CFR 50.92(c) are satisfied.
Therefore, the NRC staff proposes to determine that the amendment request j.
involves no significant hazards consideration.
t The Commission is seeking oublic comments on this proposed determination.
Any_ coanents received within thirty (30) days af ter the date of publication of this notice will be considered in making any final determination.
The Connission will not normally make a final determination unless it receives.t.
request for a hearing.

-1 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 l
period, provided that its final determination is that the amendment involves I
no significant hazards cor. sideration.
The final determination will consider all public and State comments veceived.
Should the Commission take this action, it will publish in the FEDERAL REGISTER a notice of issuance and provide for opportunity for a hearing after issuance.
The Commission expects that the need to take this action will occur very infrequently.
A request for a hearing or a petition for leave to intervene must be filed with the Secretary of the Commission, U.S. Nuclear Regulatory Commission, Washington, DC 20555, Attention:
