PALO VERDE NUCLEAR GENERATING STATION, UNITS 1,2, AND 3 CORRECTION TO NRC LEDER DATED DECEMBER 21,2010
Dear Mr. Edington:
By letter dated December 21, 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML103440282), the U.S. Nuclear Regulatory Commission (NRC) acknowledged the licensee's request to withdraw an amendment request. Following the issuance of the letter, the NRC discovered an error in the enclosure. A sentence that was supposed to indicate that additional information could be found in a meeting summary indicated instead that the additional information was listed below, which is incorrect. Enclosed is the updated page.
If you have any questions, please contact Lauren Gibson at (301) 415-1056 or via e-mail at lauren.gibson@nrc.gov.
Sincerely,

Accession No. ML102450051), by letter dated December 9, 20101* The proposed amendment would have revised Technical Specification (TS) 3.7.4, "Atmospheric Dump Valves (ADVs)," to require that two ADV lines be operable in Modes 1, 2, and 3, and when the steam generator (SG) is relied upon for heat removal, Mode 4.
The U.S. Nuclear Regulatory Commission (NRC) staff notes that its acceptance review to date has indentified that the application did not provide sufficient information to enable the NRC staff to complete its detailed review. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing.
Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the technical specifications) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required.
This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.
Therefore, if the licensee decides to re-submit the request, it must include the following information. This information was either conveyed in the NRC letter dated October 6, 2010 (ADAMS Accession No. ML102730762), or discussed in a public meeting on November 18, 2010. The meeting summary for the public meeting on November 18, 2010 (ADAMS Accession No. ML103230084), notes additional information that would have been needed to complete the technical review if the LAR had been accepted for review.

The licensee is requesting "A separate condition entry for each SG" for Condition "A" for one ADV inoperable for a 7-day completion time [(CT)].
Standard Technical Specifications (STS) do not permit separate condition entry.
Please justify why separate entry condition would be acceptable.
