NOTICE OF DEVIATION Gulf States Utilities Company Docket:
50-458 River Bend Project License: CPPR-145 As a result of the inspections conducted on September 14, 1981, and September 18, 1981, and in accordance with Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following deviations were identified.
A.
Failure to Promptly Report a Potential Deficiency in Accordence with Previous Licensee Commitments 10 CFR 50.55(e)(2) requires that the holder of a construction permit shall, within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, notify the appropriate Nuclear Regulatory Commis-sion Inspection and Enforcement Regional Office of each reportable deficiency.
In accordance with the response to an infraction identified in IE Inspec-tion Report 50-458/79-05 (Failure to Provide Timely Notification of Construction Deficiencies), the licensee committed "to inform the NRC Regional Office by telephone call within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when a problem or deficiency is discovered that could possibly be a reportable deficiency but adequate information will not be available to determine the report-ability within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery of the problem or deficiency."
Contrary to the above, on June 26, 1981, a potential problem involving possible aging characteristics inherent to ASTM A-500 Grade B steel was identified by the licensee, but was not reported to the Region IV Office as a " Potential Construction Deficiency" until September 11, 1981.
This is contrary to the prompt reporting requirements established by 10 CFR 50.55(e), and the commitments established in the licensee's response.
This appears to deviate from the licensee's commitment to NRC.
This is a deviation.
B.
Deviation From Cleaning Practices for Placement of Concrete Required By ACI 301 The River Bend Final Safety Analysis Report (FSAR), Chapter 3, Section 3.8, Volume 5, states, " Concrete protection for reinforcing, preparation, clean-ing of construction joints, concrete mixing, delivering, placing, and curing, is equal to or exceeds the requirements of ACI 301."
ACI 301-72, Chapter 4, Subparagraph 4.4, states, "All surfaces of forms and embedded materials shall be cleaned of any accumulated mortar or grout from previous concreting and of all other foreign material before concrete is placed in them."
8111270230 811103 PDR ADOCK 05000458 G
2 Contrary to the above,.in a letter dated September 4, 1981, a licensee representative issued a directive to the constructor stating, "All further concrete slab placements made on 'Q' Decking will be cleared of only large material (cans, wood, etc.) before placement.
The present practice of removing dirt, sawdust, tie wire, etc.,'is not necessary and shall be discontinued.
In all cases, the effect on che normal concrete thickness shall be the only consideration.
Thus, material in the depressed portion of the decking shall be ignored.
This practice should be implemented immediately."
This directive appears to instruct the constructor to deviate from the licensee's commitments to the cleaning practices required by ACI 301-72.
"Q" Decking is utilized as forming in various areas of Safety-Related Structures, such as the Fuel, Diesel Generator, and Auxilary Building.
This is a deviation.
Gulf States Utilities is hereby requested to submit to this office within 30 days of the date of this Notice of Deviation, a written st.atement or explanation in reply, including:
(1) the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further deviation from commitments made to the Commission; and (3) the date when full compliance will be achieved.
Consideration may be given to extending your response time for good cause shown.
The' responses directed by this Notice of Deviation are not subject to the clearance procedurrs of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, PL 96-511.
Dated November 3, 1981
