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
[[Page 11834]]
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.
