Trojan Nuclear Plant Mr. John B. Martin Docket 50-344 December 29, 1986 License NPF-1 Attachment Page 1 of 4 ENGINEERING PERFORMANCE IMPROVEMENT ACTION PLAN PGE is pursuing a comprehensive program to improve its performance of engineering in support of Trojan. The elements of the program are:
1 Assemble the design basis information associated with plant safety systems and bring this information together into an accessible controlled format.
2.
Review the operation, maintenance, surveillance, and training activities associated with plant safety systems and confirm these activities reflect design basis information.
3.
Update equipment technical manuals.
4.
Verify and update plant drawings.
5.
Update other important design documentation such as:
a.
Valve list.
b.
Piping materials and fittings list.
c.
Q List.
6.
Review the performance of the corporate engineering organization by an outside consultant.
7.
Evaluate the need for and increase resources as appropriate.
8.
Establish responsibilities and controls for specific engineering functions.
9.
Improvi specific engineering procedures.
The following description provides more information on each of these elements and provides milestone dates to measure progress and/or completion:
1.
Design Basis Documents.
System Design Basis Documents (DBD) are being prepared for identified safety-related systems to assure that the design basis are well understood and documented in an easily accessible format.
During preparation of the DBD the FSAR is being reviewed for consistency.
Although, this program does not involve a review of the original design basis information and calculations, design changes and

. calculations that have occurred since the original design will be reviewed to ensure that the original design basis is unaffected or is
. justifiably changed. The primary thrust of this effort is to assemble the design basis documentation for 12 identified systems.
These systems are:
a.
b.
Control. Building MVAC.

d.
Component Cooling Water.
e.
Containment Cooling / Hydrogen Mixing.
f.
g.
Emergency Diesel Generators, h.
125-V de and 120-V Preferred Instrument ac.
i
'i. Containment Penetrations.
J.
k.
Safety Injection.
1.
Reactor Protection.
The schedule for completion spans from December 1986 for the first system document tu September 1987 for the last system document.
Efforts will be made to expedite this work and advance the schedule as much as possible. Any associated FSAR changes will be
-incorporated in the succeeding annual update.
Since this program was originally described to you, in our letter dated May 22, 1986 (Withers to Martin), the schedule for completion has been delayed. This delay is due to problems identified in the draft for the first two system DBD and the necessary rework and improvement in the scope and level of detail in order to develop the quality desired.
2.
Operation. Maintenance. Surveillance and Training Activities Review 1
System description documents including the DBD for the 12 systems identified above will be reviewed by the Plant System Engineers and Plant training personnel. Plant training will assure that details of the design are~well understood by those who operate, maintain, and test the system. The reviews will be coordinated with scheduled work on the DBD for completion by the end of November 1987.
Plant Systeas engineers will continue to complete walkdowns of their I
applicable safety systems and will complete reviews of the system DBD, FSAR, system descriptions / technical manuals, system drawings, and maintenance, operating, and test procedures, to assure that the systems are being maintained, operated, and tested in accordance with the design and enfoty analysic.
Sy tem walkdowna will be completed by the end of December 1987.
In addition, the Quality Assurance department will perform system functional audits on two of the 12 4

3.
Updatina Equipment Tech Manuals
-The equipment technical manuals will be updated to incorporate vendor' information received and changes made to the system and equipment made since startup in 1976. This effort is scheduled to be completed in July 1987. A further review of safety-related technical manuals
~ including contacting the vendors for other additional technical information will continue through 1987.
4.
Verify and Update Plant Drawings l
f Verification and redrafting of selected plant drawings, with emphasis on safety-related electrical drawings and electrical vendor prints, will be performed in 1987. All plant drawings have been maintained in an "as-built" status since plant startup. This effort will recheck these drawings for accuracy and make the drawings more legible and easic use.
5.
Update Other Important Desian Documentation l
l a.
Valve List - This list describes all major plant valves. This l
list will be reviewed for accuracy and updated as necessary.
This list provides the design conditions and characteristics of each major valve in the plant.
b.
Piping Material and Fittings List - This list describes the design characteristics of all' piping materials and fittings used in the plant. This list will be reviewed and updated in 1987 to reflect the as-built modified status of various equipment and systems at the pJant.
c.
Q-List - The Q-List (quality list) identifies those systems components, equipment, and structures that are safety-related and quality-related. A major effort has been underway for sometime i
to revise this list to provide the additional detail for the components and equipment installed at the Trojan Nuclear Plant.
This effort is expected to be completed by December 1987.

Corporate Enmineerina Organization Performance Review General Electric Corporation (GE) was retained by PCE to do an independent outside review of our offsite engineering organization and its performance. The report concludes that PGE performs engi-neering work by means of a technically competent staff but on occasion the performance has been degraded due to nontechnical issues such as management techniques, organization, and scheduling and I
planning. The report identified several significant issues and L
proposed a priority for their rerolution. PGE plans to address a minimum of six of the highest priority issues during the calendar year 1987. This process will involve management in a structured problem-solving technique to validate the problems, determine the best solution, and establish an implementation plan and schedule.
7.
Resources PGE has initiated an effort for several years now to continually evaluate the need for increasing resources as appropriate.
In 1986, 71 new full-time positions were created. The budget for 1987 includes a similar number of new full-time positions. PGE will continue to use capable contractors as necessary to provide support of engineering activities.
8.
Responsibilities and Controls of Specific Functions PGE will continue to look at specific functions performed by NPE or the Trojan Plant Engineering staff to ensure clear assignment of responsibility and adoquate controls are established for their performance. For example, in 1987, the engineers and technical support people responsible for ISI and welding will be transferred onsite to better support plant activities and to improve the engi-neering involvement in these plant activities. This relocation of personnel will occur immediately following the 1987 refueling outage.
9.
Improve Specific Engineerina Procedures Engineering procedures for performing and checking calculations used to accomplish safety-related design modifications and the preparation and documentation of computer programs will be reviewed and revised as necessary. Revisions to these procedures will be accomplished by June 30, 1987. Other procedures will be reviewed in the course of the specific engineering improvement activities described previously, and will be improved as the opportunity permits.
