Independent Program items is given in Attachment I, together with a

brief indication of the status of each item. A summary of Attachment

I is given in Table l. Although Phase II of the IDVP has not been

approved, Stone and Webster Engineering Corporation (SWEC) has been

performing Phase II work under the direction of TES. During thisreport period, SWEC has identified certain items related to Phase

II. These items are listed in Attachment I with file numbers in the

8000 series. PGaE will report Phase II items as a separate list once

Phase II is approved by NRC.

In addition, attachment IA indicates the Project status, includingthe expected Project resolution date, for each of the items that have

not been issued as a Completion Report.

I. Annulus Review

This subsection provides a description of PGandE's progress inresolving concerns identified during review of the annulus design.Issues which were described in this section in previous reports butwhich are not now listed here, such as mechanical, piping, and

conduit supports, are now complete.

Civil En ineerin

Structures

The confirmatory analysis of the steel annulus structure iscontinuing. This analysis accounts for loadings from as-builtmechanical equipment and piping. All members and their connections

will be evaluated for Hosgri, DDE, and DE loads. The examination ofthe structure for Hosgri loads is complete, including the design ofmodifications. Confirmatory analyses of this structure for DE and

DDE are in progress. The status of structural review for otherstructures are discussed below.

Corrective Action Pro ram

Status reporting for each particular piping issue, identified as an

Open Item by the Internal Technical Program and listed in Attachment

III, has been discontinued. The status of piping review is now

given on Table 2.
