SUBJECT:

THREE MILE ISLAND NUCLEAR STATION, UNIT NO. 1 - CORRECTION OF ERRORS IN AMENDMENT NO. 255 RE: EXTENSION OF REACTOR TRIP SYSTEM AND REACTOR TRIP DEVICE FUNCTIONAL TEST INTERVALS (TAC NO. MC4903)

Dear Mr. Crane:

On August 10, 2005, the Nuclear Regulatory Commission (NRC) staff issued the subject Amendment No. 255 to Facility Operating License No. DPR-50 for the Three Mile Island Nuclear Station, Unit 1, in response to your application dated October 20, 2004.

After issuance, the NRC staff noted a number of errors. The Docket No. was typed as "50-219" where it should be "50-289." The License No. was typed as "DPR-16" where it should be "DPR-50." In addition, there were a number of typographic errors involving punctuation marks, misused upper case, misspelled word, etc. Accordingly, we are re-issuing both pages of the amendment, and page 4 of the safety evaluation. This discovery of errors did not change the NRC's staff's conclusion on the subject amendment.

We apologize if these errors caused you any inconvenience.

Sincerely,

/RA/

AMERGEN ENERGY COMPANY, LLC DOCKET NO. 50-289 l THREE MILE ISLAND NUCLEAR STATION, UNIT NO. 1 l AMENDMENT TO FACILITY OPERATING LICENSE Amendment No. 255 License No. DPR-50

1. The Nuclear Regulatory Commission (the Commission) has found that:

A. The application for amendment by AmerGen Energy Company, LLC (the l licensee), dated October 20, 2004, complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's rules and regulations set forth in 10 CFR Chapter I; B. The facility will operate in conformity with the application, the provisions of the Act, and the rules and regulations of the Commission; C. There is reasonable assurance: (i) that the activities authorized by this amendment can be conducted without endangering the health and safety of the public, and (ii) that such activities will be conducted in compliance with the Commission's regulations; D.

FOR THE NUCLEAR REGULATORY COMMISSION

Attachment:

Changes to the Technical Specifications Date of Issuance: August 10, 2005 Corrected by letter dated August 30, 2005 l

to be essentially the same as reported for the Oconee RTS design group in BAW-10167A, Supplement 3, and the STI extension is found to be an insignificant contributor to system unavailability or core damage risk. The licensee evaluated the recent 10 years worth of relevant plant-specific RTB failure-to-trip data to establish RTS unavailability at TMI-1. The licensee reported that only one RTB failure-to-trip incident was identified. In this failure, only the undervoltage (UV) trip device failed during monthly testing of the RTB while the redundant shunt trip device (temporarily bypassed to perform UV device test) was operable to trip the RTB. This demand-related failure rate is consistent with the expected frequency of one UV trip device failure in 11 years assumed in BAW-10167A, Supplement 3. The licensee stated that the failure experience from TMI-1 since publication of the topical report does not contradict any of the assumptions or conclusions of BAW-10167A, Supplement 3, or the NRCs associated SE.

Based on the above evaluation, the NRC staff finds the licensees justification for extending the TMI-1 reactor trip devices STI from monthly to quarterly sufficient. The licensees proposed extension is, therefore, acceptable.

3.3 Proposed TS Bases Changes The licensee also proposed to revise the associated TS Bases (contained on Page 4-2a and 4-2b of the TSs) associated with the above TS changes. The NRC staff reviewed the proposed changes and found the proposed changes to the TS Bases consistent with the proposed TS changes.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Pennsylvania State official was notified of l the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (69 FR 68181). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
