APPENDIX A Notice of Violation Gulf States Utilities Company Docket No. 50-458 CPPR-145 As a result of the inspection conducted on November 18-21, 1980, and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violations were identified:
Criterion V of Appendix B to 10 CFR 50 requires that activities affecting quality be prescribed by documented procedures of a type appropriate to the circumstances, and shall be accomplished in accordance with these procedures.
a.
Stone & Webster (S&W) Specification No. 210.370, Revision 5, " Placing Concrete and Reinforcing Steel," on page 1-44, states " Scaffolding, lighting, communication equipment, and other mechanical aides that can improve the steel and concrete placement shall be used wherever practicable."
Contrary to the above:
The IE Inspector observed that, during concrete placement No. SC4-W-85-7 (a3'-6"extgriorradfuswallintheNo.1StandbyCoolingTower,between azimuths 150 and 180, from elevation 64'-6" to 84'-6") no lighting was utilized to provide visibility at the bottom of the form.
During that portion of the placement witnessed by the IE Inspector, the S&W QC Inspector was observed to be performing his inspection from the top of the formwork.
In addition, the IE Inspector verified that the S&W Quality Control Inspector was not in possession of a flashlight.
Available light was such that the bottom of the form was dark and not visible.
This is a Severity Level V Violation (Supplement II, paragraph E).
b.
Stone & Webster Quality Assurance Directive No. 10.2, Revision B,
" Inspection of Batch Plant, Concrete, Reinforcing Steel, and Grout,"
paragraph 5.1.3 states, " Water additions shall be checked to assure the amount prescribed in Reference 2.2 is not exceeded."
Reference 2.2, S&W Specification No. 210.350, " Specification for Mixing and Delivering Concrete," requires a maximum water to cement ratio of 0.394 for the applicable mix (H3).
Contrary to the above:
The IE Inspector observed that, during concrete placement No. SC4-W-85-7, batch ticket No. 14335 indicated that the addition of 10 gallons of water was allowed; whereas 12 gallons were actually added.
Computation of the actual water to cement ratio, from the information on the batch ticket, resulted in a value of 0.397.
The concrete truck was not rejected and the concrete was placed.
This is a Severity Level V Violation (Supplement II, paragraph E).
