APPEND Q B NOTICE OF DEVIATION TU Electric Dockets: 50-445/87-35 50-446/87-26 Comanche Peak Steam Electric Station, Permits: CPPR-126

?] nits 1 and 2, Glelt Rose, Texas CPPR-12'i The following deviraions were identified during inspections conducted on December 2, 1987, through January 5, 1988.

A. Appendix A to Project Instructjon (PI) PI-0210'053a001, Revision 6, "Checking Procedures," states, in part, "Tne ,

purpose of an engineering check is to provide assurance that a '

tasx is performed and documented thoroughly and that the ,

results are correct and reasonable . . . .

Further, Section F of this appendix to the PI, states, in part, "Once an item has beca checked and approved, it should 1 not be altered without issuing a revision of the item.".

Cont'eary to the above,

1. In the calculati_n package for the Level 5 support evaluation A02454, on pages 15 end 16 of 39, the person checking the calculations dated them March 10, 1987, prior to the date of the calculations (March 11, 1987).

The support load calculations in this package were

' performed on March 20, 1987, aCd checked on March 23, l 1987. The summary Of loads on page 19 or 39 was dated March 9, 1987, and checked on March 10, 1987, which is 1 before the date indicating when the calculations were  :

performed.

l

2. Cn page la of 63, of Calculation A-02151 for Room 148B,

entitled "Open Items", the checker indicated that his work was completed on January 6, 1987; however, the preparer signed and dated this document on January 7, 1987.

I These two examples comprise a deviation (445/8735-D-01).

D, Section 4.1, "Walkdown Guidelines," to Project Instruction PI 0210-052-004 provides checklists for documentation, tolerances for dimensions, and guidelines for performing the' i conduit routing valkdowns. The instruction requires an.,

of the junction box was located 171/ 2" away from the  !

NQ-06004/A-02168 to the rise in elevation of the condui?.  !

to the bolted junction box tagged NQ-08650 snus documented

~

by the walkdown engineer to be 22". The NRC inspector l measured this length to be 13".

4. In Room 148B, the overall lergth of the P1001 Unistrut l i member of the Type 7 support tagged NQ-06002/A-02160,  :

L shown on page 26 of 43 for calculation A-02151 was

, documented by the walkdown engineer to be 10". This  ;

1 length was measured to be 8" by the NRC inspector.  ;

These four examples ccmprise a deviation (445/8735-D-03).  !
