W. S. Little, Director, Braidwood Project, DRP

SUBJECT:

BRAIDWOOD FINAL WALKDOWN INSPECTIONS The final resolution of some of your assigned hearing issues may depend on the results of final walkdown inspections. Attachment 1 is a draft list of walkdown inspections, and their status, to be completed prior to Braidwood  :

Unit 1 fuel load. This is for your use in planning and carrying out your inspections. For those walkdowns associated with hearing contentions which  ;

are not yet complete, our draft hearing testimony will be based on your review of Ceco's written, approved procedures, and on the fact that we will inspect to verify that the walkdowns were conducted properly and that any identified deficiencies are properly resolved.

l During our seminar on Braidwood on February 12, 1986 Messrs. McGregor and Schulz expressed dissatisfaction with Ceco's program for walkdown inspecitons to identify potential piping interference problems. I asked that they document their concerns so that they could be given proper consideration during our inspections of these issues. Their concerns are documented in Attachment 2 and 3. In your inspection efforts please take their concerns into consideration when resolving issues involving final walkdown inspections.  ;

In eferc'nce to ynor January 27, 1986 memorandum, I am concerned about piping electrical, and HVAC interferences and any potential impact on plant safety.

PRS has not, as of this dat e, informed me of their general satisfaction with CECO's program, t:rr;o r. program f on- inter f er ence control was revised in the Fall of 1984 and up s , et that time, adequate to identify and resolve piping, electrical, and I tynr i nt er f er ences f or preserit and future installations. However, for the yrmar s ni construction pri or to the Fall of 1984, controls were not adequate.

Of course, this concern was also echoed by the CAT inspection team in W6fn4-44; 457/04-40. My concern is not whether the detailed walkdown of the 100 F and greater lines (thermal movement) prior to fuel load is adequate; bu-ii the " general walkdowns" by CECO (del i neated in their NRC answer to the cosit ention and i n their February 13, 1985 letter to the NRC responding to the ilRC inspection report 456/84-09; 457/84-09) are adequate f or piping lines les than IBOU F and f or electrical and HVAC interferences. Factors to consider ar accessibility of components for maintenance, and blockage - such as inability to 1.or n a val ve or open a cabinet / Junction b o:: . The piping as-built drawings e.hich have been and are being done, do not take into consideration itterferences that may have resulted from the electrical contractor and/or llVAC contractor installing components after the piping as-built was completed l

I W. !i. La til e 2 January 30, 1986 I believe a meeting i s necessary between DRS and the residents to alleviate or resolve any concerns. My desire is to ensure no saf ety problems exist and that we, the NRC, are on solid ground wi th respect to all aspects of this incue. Possibly the pre-operational testing by the licensee and the general wallidowns of all . the site contractor installations will resolve the issue, r ather than a detailed wall.down as required of the piping lines greater than 109 F. The Senior Resident Construction would appreciate being inf oreec' of DRS's conclusions and recommendations due to their expertise in this area.

Residents during an April-flay 1994 meeting withThe theconclusion licensee and by the Architect Engineer at the Braidwood site. and the licensee at both meetings was that the problem was real that system walkdowns seere necessary In January, to document 1985,these during the NRC '

interf erences and resolve them. 11, 1995, in a DRP meeting, the CAT subject meetings and again of clearances and onpipe Marchinterferences were discussed.

1986, I did not L..aring the Braidwood SALP meeting of January 22,(which has changed express dissa+1sfaction with the CECO program, from a system walkdown with resolution of clearance problems to a walkdown of only systems which are elevated in temperature prior to licensing) but a question as to the ability, within the time j

restraints, f or CECO to adequately inspect, document, evaluate l

and reroute, if necessary, all systems with negative clearance or l

interference problems.
