COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NO. 50-445 ELECTRICAL RACEWAY SUPPORT SYSTEM SDAR:  CP-85-31 (INTERIM REPORT)
Gentlemen:
On December 5, 1986 we notified you by our letter logged TXX-6138 of a deficiency involving the Unit 1 Class 1E Electrical Raceway Support System which we deemed reportable under the provisions of 10CFR50.55(e). This is an interim report submitted to status corrective actions implemented to date.
Our latest report, logged TXX-6534 was submitted June 26, 1987.
This deficiency involves the installation of Separation Barrier Material (SBM) and Radiant Ene gy Shield (RES) material on Unit 1 Class lE Electrical Conduit Raceways without engineering interdisciplinary design review of the proposed change.
As a result of refined engineering analysis, the corrective action required                      I has been redefined as follows:
                     -Three conduit runs identified as overstressed will require the addition of twenty new supports.
                     -Fourteen existing supports identified as overstressed will be modified.
The physical rework associated with this corrective action is continuing.
