Dear Mr. Seidle:

i 5 River Bend Station - Unit 1 j Refer to: RIV

Docket No. 50-458/Rpt. 80-06 i

4 i This letter respcnds to the item of noncompliance and the l deviation contained in I&E Report No. 50-458/80-06. This in-spection at the River Bend construction site was conducted by Mr. A.B. Beach and other members of your staff during the periods June 9-10, June 24-27, and June 30-July 3, 1980, of c:tivities authorized by the NRC Construction Permit No. CPPR-145 for River Bend Unit No. 1.

We trust that the enclosed response satisfactorily answers the

! concerns raised in your report. We shall be glad to discuss any further points that you may have.

Sincerely,

h. E E. L. Draper, Jr. dbi l Vice President - Technology ELD /WJR/mb t

RESP 0NSE TO NOTICE OF VIOLATION j A Failure to Follow Procedures for the Identification of Training Needs j Criterion V of Appendix B to 10 CFR 50 requires that activities 4 affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances, and shall be accomplished in accord-ance with these procedures.

l, 1 Stone and Webster Training Procedure CMM-9.1, " Construction Training j Program," requires, in Section 5.5, that each supervisor be responsible j for identifying construction training needs to the Construction Training

! Supervisor.

! Contrary to the above:

i i On June 26, 1980, the IE inspector was informed by the licensee and

] contractor personnel that supervisors were not identifying training ,

i needs to the Construction Training Supervisor.

} This is an infraction.

l i

J GSU Response to Infraction A i

l Action taken and results achieved:

l l S&W Procedure CMM-9.1 has been superceded by CSI 1.0.21 which requires that the _Coastruction Training Staff conduct a training j needs survey with the discipline supervisors and department

! heads. This survey has been completed and the resulting infor-

mation was used in the development of the Computerized Training i Record System (CTRS). The' Computerized Training Record System j (CTRS) was implemented on July 25, 1980. All training records have been entered into the program and reports have been issued j to provide an effective way to identify individual training needs.

< Corrective Action taken to prevent further noncompliance: ,

! CTRS system will be updated on a. weekly basis and the Construction

Training department will maintain listings of those personnel who

]

received training on safety related activities. This information i will be provided to the discipline supervisors.

1 l Stone & Webster is in the process of developing a detailed schedule for the required craft training for safety related work as outlined in CSI 1.0.21. It is anticipated that the detailed schedule will be completed by the end of September, 1980.

Date when full compliance will be achieved:

( Full compliance to this infraction was achieved July 25, 1980, with the implementation of the CTRS Program.

ATTACHMENT II RESPONSE TO NOTICE OF DEVIATION A Use of Air-Entrainment Admixture in Category I Concrete The River Bend PSAR, in Section 3.8.4.6, requires that all concrete l used in seismic Category I structures shall contain an air-entraining agent in an amount sufficient to satisfy ACI 301-72, Table 3.4,

" Total Air Content for Various Size of Coarse Aggregate for Normal Weight Concrete." For concrete mixes using #57 coarse aggregate, the total air content limits would be 3.5% - 6.5%.

Contrary to the above:

l Stone and Webster Specification 210.350, " Specification for Mixing and Delivering Concrete," deletes the minimum total air content l

requirement in seismic Category I structures for structures below the frost line and interior walls above the frost line. In a review of placement records covering seismic Category I structures, at least sixteen (16) of the total air content values were below 3.5%. (Total air content values for placement ABI-M-79E5 were as low as 1.9%.)

Thus, the specification requirement appears to deviate from the PSAR commitment to the total air content values in Tc' ale 3.4 of ACI 301-72.

l This is a deviation.

GSU RESPONSE TO DEVIATION A Action taken and results achieved:

The intent of the PSAR commitment to ACI 301-72, Table 3.4, is that the table be used in conjunction with the clarifying text contained in ACI 301-72, Section 3.4, subsection 3.4.1.

This subsection requires air-entrainment to improve durability in concrete, which will be subject to potentially destructive exposure, i.e.: freezing and thawing. The above reference placements were structures that will not be subject to those potentially destructive exposures.

It is recognized that the text of the PSAR should be appropriately clarified to indicate the use of Section 3.4 of ACI 301 42. Such a clarification is under review at this time. In addition, Stone and Webster Site Engineering has directed, in Inter-office Memorandum dated July 18, 1980, that efforts be made to place all concrete closer to the mix design air content range in order to improve workability and placeability.

Corrective Action taken to prevent further deviation:

No additional action required.

l l Date when full compliance will be achieved:

1 \

PSAR clarification will be completed by first of September, 1980. l l
