NUCLEAR REGULATORY COMMISSION

[Docket No. 72-26; NRC-2012-0312]


Pacific Gas and Electric Company; Diablo Canyon Independent Spent 
Fuel Storage Installation

AGENCY: Nuclear Regulatory Commission.

ACTION: License amendment; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is amending 
Materials License No. SNM-2511 for the Diablo Canyon (DC) independent 
spent fuel storage installation (ISFSI). Amendment No. 3 provides the 
following: (1) Changes the maximum allowable decay heat per storage 
location; (2) adds a new helium backfill pressure range for 
multipurpose canisters (MPCs) with heat loads less than or equal to 
28.74kW, (3) clarifies that supplemental cooling was only applicable 
for unloading of high burnup fuel loaded in 2012 under the provisions 
of License Amendment No. 2, and (4) provides a maximum average yearly 
temperature of 65[emsp14][deg]F as the basis for a loaded overpack in 
the cask transfer facility, or storage on the ISFSI pad, and a maximum 
temperature of 100[emsp14][deg]F, averaged over a 3-day period, as the 
basis for transfer activities in the transfer cask to support revised 
thermal analyses.

SUPPLEMENTARY INFORMATION:

I. Introduction

    By letter dated July 31, 2012, as supplemented March 14, May 23, 
and September 5, 2013, PG&E submitted license amendment request (LAR) 
12-003 (ADAMS Accession No. ML122270603) to the NRC to amend Materials 
License No. SNM-2511 for the DC ISFSI in accordance with 10 CFR Part 
72. PG&E's application requested that the ISFSI Technical 
Specifications (TS) be revised as follows:
    1. Tables 2.1-7, 2.1-8, and 2.1-9 in TS 2.0, ``Approved Contents,'' 
are revised allowing up to a 28.74kW heat load for uniform loading and 
25.572kW heat load for regionalized loading. This changes the maximum 
allowable decay heat per storage location, in watts, determined from 
Table 2.1-7 or 2.1-9 to be consistent with this proposed license 
amendment request. Table 2.1-8 is revised to delete the note that 
limits Zirlo clad fuel to a burnup of 45,000 MWD/MTU and replace the 
existing Note 3 with a note that refers to TS 2.3, ``Alternate MPC-32 
Fuel Selection Criteria.''
    2. TS 2.3, ``Alternate MPC-32 Fuel Selection Criteria,'' is revised 
to add reference to Table 2.1-9 as regionalized loading of high burn-up 
fuel (HBF).
    3. TS 3.1.1, ``Multi-Purpose Canister (MPC),'' Surveillance 
Requirement (SR) 3.1.1.2 is revised to add a new helium backfill 
pressure range for MPCs with heat loads less than or equal to 28.74kW.
    4. TS 3.1.4, ``Supplemental Cooling System,'' Applicability is 
changed to only be applicable for unloading of high burnup fuel loaded 
in 2012 under the provisions of License Amendment No. 2.
    5. Addition of TS 4.1.3 Design Features Important to Thermal 
Analysis-
    a. A maximum average yearly temperature of 65[emsp14][deg]F is the 
basis for a loaded overpack in the cask transfer facility, or storage 
on the ISFSI pad.
    b. A maximum temperature of 100[emsp14][deg]F, averaged over a 3-
day period, is the

basis for transfer activities in the transfer cask.
    In accordance with 10 CFR 72.16, a Notice of Docketing and 
Opportunity to Request a hearing was published in the Federal Register 
on January 2, 2013 (78 FR 123). On February 11, 2014, the NRC approved 
and issued Amendment No.3 to Materials License No. SNM-2511 (ADAMS 
Accession No. ML14043A517), held by PG&E for the receipt, possession, 
transfer, and storage of spent fuel at the DC ISFSI. Amendment No. 3 
was effective as of the date of issuance. Pursuant to 10 CFR 72.46(d), 
the NRC is providing notice of the action taken.
    Amendment No. 3 complies with the standards and requirements of the 
Atomic Energy Act of 1954, as amended (the Act), and the NRC's rules 
and regulations. As required by the Act and the NRC's rules and 
regulations in 10 CFR Chapter I, the NRC has made appropriate findings, 
which are set forth in the Amendment No. 3 safety evaluation report 
(SER) (ADAMS Accession No. ML14049A476). Also as described in the SER, 
the NRC determined that issuance of Amendment No. 3 meets the criteria 
specified in 10 CFR 51.22(c)(11) for a categorical exclusion. Thus, the 
preparation of an environmental assessment or an environmental impact 
statement is not required. On February 11, 2014, the California Energy 
Commission was informed of the NRC's action. The state had no comments.

II. Further information

    The NRC has prepared an SER that documents the staff's review and 
evaluation of the amendment. In accordance with 10 CFR 2.390 of NRC's 
``Rules of Practice,'' final NRC records and documents related to this 
action, including the application for amendment and supporting 
documentation, and the SER, are available electronically at the NRC's 
Electronic Reading Room, at: http://www.nrc.gov/reading-rm/adams.html.
