Dear Commissioners and Staff:

Pursuant to 10 CFR 50.71(e), 10 CFR 50.54(a)(3), and 10 CFR 50.4(b)(6), Pacific Gas and Electric Company hereby submits the Diablo Canyon Power Plant (DCPP)

"Final Safety Analysis Report Update" (UFSAR), Revision 22.

As a minimum, DCPP UFSAR, Revision 22, reflects changes made under the provisions of 10 CFR 50.59, Enclosure 1 identifies the 10 CFR 50.59 Evaluations.

There were no changes made to Revision 22 of the DCPP UFSAR as a result of license amendments.

Enclosure 2, Table 1 provides a listing of the revised drawings from UFSAR Table 1.6-1, "Controlled Engineering Drawings." Enclosure 2, Table 2 provides a listing of the new drawings added to UFSAR Table 1.6-1, "Controlled Engineering Drawings." Tables 1 and 2 contain a column titled "Folder" to identify the folder on the compact disc (CD) that contains the corresponding drawing. File A contains drawings that passed the Optical Character Recognition (OCR) and File B contains files that are acceptable but were too large to pass the OCR process.

Enclosure 3 contains DCPP UFSAR, Revision 22, including the new and revised drawings listed in Enclosure 2, on one CD, labeled "Diablo Canyon Power Plant FSAR Update, Revision 22," dated May 2015. The contents are in Adobe Acrobat portable document format.

The CD contains the following files:

Enclosure 1 PG&E Letter DCL-1 5-060 Changes Incorporated into the Diablo Canyon Power Plant Final Safety Analysis Report Update, Revision 22 Resulting from 10 CFR 50.59 Evaluations

Enclosure 1 PG&E Letter DCL-15-060 Changes Incorporated into the Diablo Canyon Power Plant Final Safety Analysis Report Update, Revision 22 Resulting from 10 CFR 50.59 Evaluations Number(l) Description 2013-021 Disable (remove from scan) the Unit 1 Thot resistance temperature detector Loop 3 input to the reactor vessel level instrumentation system Train A.

2013-026 DDP, 2 , 1000024907: Update the acceptable air flow rates for the Containment Fan Cooler Units.

2013-029 Change the current licensing basis to describe the square-root-of the-sum-of-squares method and the absolute sum method as alternative acceptable methods for the combination of seismic faulted condition (Double Design Earthquake or Hosgri Earthquake) loads with loss-of-coolant accident loads in the evaluation of ASME Section III, Class 1, Reactor Coolant System components.

2013-030 DDP 1000024947: The temperature response due to a main steam line break (MSLB) in the Turbine Building and in the Auxiliary Building Area L is increased due to implementing a more conservative set of MSLB mass and energy releases and superheated steam effects that are based on the replacement steam generators.

Revised the UFSAR to describe the use of the GOTHIC computer code to perform the compartment temperature response for these areas instead of the PCFLUD code.

2015-002 The activity involves changing the computer program used for the structural analysis of reactor coolant pressure boundary components, structures, and supports, and reactor vessel (RV) internals to ANSYS.

2015-004 Change the current licensing basis to establish 76°F as the design basis outdoor ambient temperatures for Heating, Ventilation, and Air Conditioning, replacing the original design value of 82 0 F and an estimated maximum temperature (representing a "worst case" design condition) of 90°F.
