April 19, 2005 Mr. Karl W. Singer Chief Nuclear Officer and Executive Vice President Tennessee Valley Authority 6A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801
SUBJECT:
BROWNS FERRY NUCLEAR PLANT, UNIT 1 LICENSING ACTION STATUS AND INTERDEPENDENCIES (TAC NOS. MC1330, MC1427, MC2305, MC3812, MC3813, MC3822, MC3960, MC4070, MC4161, MC4659, MC4797, MC5254, AND MC5373)
Dear Mr. Singer:
The Tennessee Valley Authority (TVA, the licensee) has submitted 13 license amendment requests (TS-426, TS-427, TS-428, TS-430, TS-431, TS-432, TS-433, TS-434, TS-435, TS-436, TS-437, TS-438, and TS-447) since November 2003 in support of the recovery activities for Browns Ferry Nuclear Plant, Unit 1 (BFN1), excluding the license renewal application (LRA). In addition, there are two license conditions that must be satisfied prior to BFN1 restart. The U.S. Nuclear Regulatory Commission (NRC) staff is issuing this letter to confirm our understanding of the interdependencies and to provide the status of licensing actions.
A listing of the license amendment requests citing outstanding information is contained in. This table also provides an updated list of the license amendment applications that involve instrumentation setpoints that were developed using Instrumentation, Systems, and Automation Society of America (ISA) Standard ISA-S67.04-1994 Method 3. This update includes one amendment package that was inadvertently omitted and corrects one typographical error from our letter dated January 6, 2005, on the subject of license amendment applications using Method 3. provides a listing of licensing actions that includes TVAs requested completion dates and interdependencies. The interdependencies are graphically depicted in Enclosure 3.
The NRC staff has found that, in general, the submittals provided by TVA have clearly identified the interrelationships between the requested license amendments. Nevertheless, the NRC staff is requesting TVA confirmation that our understanding of the interdependencies is correct.
The NRC staff is concerned that delays in the review or the denial of one licensing action may have an adverse effect on multiple other licensing actions, including the license renewal review.
For example, the scope of the license renewal application review is dependent on the license amendment request associated with the allowable main steamline isolation valve leakage limits (TS-436). The NRC staff believes that a complete, high quality, and timely response to NRC staff questions is critical to the timely review of your applications.
K. W. Singer The NRC staff has noted that several of the applications contain multiple parts that could be split into stand-alone licensing actions. For example, TS-447 contains a request to change both limiting safety system setpoints and the surveillance frequency. In some cases, portions of the amendment request could be reviewed and issued separately while technical issues are being resolved for the remainder of the amendment request. In the future, TVA may want to consider revising the scope of these applications in order to expedite NRC staff review and approval.
Due to scheduling considerations and as requested in your letter dated January 7, 2005, the review of your LRA will be based on currently licensed thermal power limits for each of your units. The extended power uprate (EPU) review will address EPU conditions for the renewed license term later. The NRC staff will be reviewing the two applications to the level of detail necessary to reach a finding of compliance with the applicable regulations. While every effort will be made to avoid overlap and duplication of reviews, the NRC staff may not completely preclude revisiting some of the license renewal issues, such as any intervening aging management program review changes, including any current licensing basis changes, during the conduct of the EPU review.
The NRC staff is reviewing closure packages for Generic Communications and Special Programs applicable to BFN1 during the period from 1985 through the present to verify that all required submittals are being tracked in your periodic Status of BFN1 Restart Issues report.
The results of that review will be the subject of separate correspondence. These results may potentially impact the LRA review.
The NRC staff discussed this request with Mr. Tim Abney on April 6, 2005, and he agreed that a response would be provided within 30 days of the date of this letter.
If you have any questions, please contact Ms. Margaret Chernoff at (301) 415-4041 or Ms. Eva Brown at (301) 415-2315.
Sincerely,
/RA/
