STN 50-498, STN 50-499 Extension of Implementation Time for Amendment Nos. 136 (Unit 1) and 125 (Unit 2),
Relaxation of Allowed Outage Times and Bypass Test Times for Instrumentation

==Reference:==
Letter, M. C. Thadani to W. T. Cottle, "Issuance of Amendments Revising Allowable Outage Times and Bypass Test Times for Instrumentation (TAC Nos. MB2138 and MB2139)," dated March 19, 2002. [ST-AE-NOC-02000932]
The reference letter issued Amendment 136 to Facility Operating License NPF-76 and Amendment 125 to Facility Operating License NPF-80, for South Texas Project Unit 1 and Unit 2, respectively.
These Amendments permit the relaxation of the Allowed Outage Times and Bypass Test Times for the Limiting Conditions of Operation in Technical Specification 3.3.1, "Reactor Trip System Instrumentation," and Technical Specification 3.3.2, "Engineered Safety Features Actuation System Instrumentation."
STP requested, and the NRC approved, a 30-day implementation period associated with issuance of these Amendments. As discussed on April 16, 2002, in a teleconference with Mr. M. Thadani, additional time will be necessary to incorporate actuation logic and relay unavailability and risk into the Configuration Risk Management Program. Per our discussion it is our understanding, unless informed otherwise by the NRC, that STP has been permitted until May 31, 2002, to implement these Amendments.

NOC-AE-02001306 Page 2 Additionally, we noted during previous discussions a wording difference between our submittal and the associated NRC Safety Evaluation Report (SER). As we discussed, the Safety Evaluation stated (Page 5, paragraph 3 of the SER) that "the status of the bypassed channel will be indicated in both the control room and locally," whereas our submittal stated "the status of the bypassed condition will be indicated in both the control room and locally." As we discussed with Mr. Thadani, it is our understanding that this difference in wording does not reflect a misinterpretation regarding the design of our planned bypass testing modification (i.e., "channel" vs. "condition"), but is merely a minor variation in wording with no change in design requirements implied.
There are no new commitments made in this letter.
If you have any questions on this amendment application, please contact either J. R. Morris at (361) 972-8652 or me at (361) 972-7136.
