e- O WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT NO. 2 Docket No. 50-397 License No. CPPR-93 Johnson Controls Design Issue INTERIM REPORT Description of Potential Defect or Noncompliance Burns and Roe (BRI), the Architect-Engineer, conducted a Technical Audit of Johnson Controls Incorporated (JCI) to confirm piping instrumentation design adequacy. The JCI organization performs small bore (l" and under) piping design work and installation on the WNP-2 project. JCI requires interface design information from BRI to perform their design work. The audit determined that the large bore piping thermal movement data being utilized by JCI could not be traced by BRI documentation. The information that was being utilized was also found to be discrepant. A reevaluation of the design utilizing the most current thermal movement information provided by BRI resulted in identification of six small bore pipe lines which were overstress by ASME code criteria.

Analysis of Safety Implication Based on the most conservative assumption that the overstressed condition would have led to simultaneous multiple small bore piping failures, there would have been a loss of various instrumentation. The most significant instrumentation loss would have been the automatic main steam line isola-tion and feedwater control on steam line "D". Other control functions would also be affected having varying safety and operational implications.

Therefore, the condition is considered to be reportable.

Corrective Actions Taken BRI has issued current thermal displacement data to JCI and is updating that information to be current with the latest large bore piping analysis.

JCI is now reevaluating their small bore design based on the most current information. JCI has issued corrective action on the six lines which were

! overstressed.

Line 37F - Rerouted Piping 39e - Replaced hanger with snubber type support 42a - Revised support from two-way to three-way i 69a - Revised support from two-way to three-way l 70e - Revised support from two-way to three-way 75e - Rerouted Piping Field revisions are expected to be completed prior to the end of August 1982.
