Potential Problem After Bechtel's receipt of the Callaway/Wolf Creek 10CFR 50.55(e) report concerning Corner & Lada Sway Struts, dated July 24, 1980, an inspection was initiated to re-view the Sizes 1, 2 and 3 sway struts delivered to the PVNGS jobsite. The following conditions have been identi-fied as potential deficiencies:

1. Loose bushings in Size 2 and 3 sway struts at, the pipe clamp end can result in the paddle becoming completely disengaged from the bushing, causing a 3/8" gap between paddle and pin.

2. Existence of a 3/8" gap between the paddle and pin during a seismic event, may result in piping and/or piping welds being over-stressed due to movement of the piping system.

II. A roach To and Status Of Pro osed Resolution The subject sway struts which have been received and/or installed are being located and identified by Bechtel Construction. The Corner & Lada Field Representative will meet with Bechtel Construction to review the sway struts and to agree upon the disposition of this condi-tion. The corrective action plan will be either repair or replace any deficient sway struts that are found following established Nonconformance Report (NCR) pro-cedures.
