Dear Mr. O'Reilly:

This letter provides an updated plan and schedule for the completion of all open items associated with IE Bulletins 79-02 and 79-14.

l Af ter Mr. W P. Ang's inspection in April 1983, (IER-83-11) an extensive review of all~ the-inspections and calculations performed per the requirements of the Bulletins was initiated. This review was prompted by a number of paperwork discrepancies identified by Mr._Ang during his reviews. Our subsequent detailed review identified an extensive amount of work required to verify and document the accuracy of the field information and the proper transcription of this information to the "as-built" design documents. Our reviews further identified that-the deficiencies requiring verification and clarification did not result in any operability concerns. Based on the results of these reviews, a plan and schedule were developed to complete all Bulletin work.

The Bulletin closeout was divided into specific tasks. The following is a brief description of each task.

1)

Using the various revisions of the field data, verify that design isometrics are geometrically drawn. Geometric discrepancies between revisions of field data are field verified, and design isometrics are corrected es necessary.

2)

Convert chart method analyses to the static computer method.

3)

Using the various revisions of field data, sketch "as-built" drawings of each seismic restraint.

Identify any data relative to design that is not 8402290071 040215 l(

Although major modificacions are not expec't'ed, it is considered likely that some minor modifications may be necessary to some restraints. This is most likely on the-piping previously analyzed by the simplified (chart) method.. Any modifications determined to beinecessary will be' factored into the current outage schedule.. All inspections, "as-built" documentation, procedure changes, and modification identification are scheduled for completion by June 30, 1984, with modifications-to restraints scheduled for completion by the end of the Steam Generator Replacement Outage. Any necessary changes to this schedule due to' unforeseen.outa8e interferences or scope changes will be reported to you

-promptly.
