Pipe coating facilities I l Examination of concrete aggregate storage facilities disclosed

improper stockpiling of fine and ccarse aggregates. Specification number P815-1109.00-00-001 and referenced ACI Standard 304-73, Paragraph 2.1.3, require concrete aggregates be stored so as to prevent overlapping of different sizes.

(; Contrary to the above, the inspector found fine and coarse aggregate - stockpiles exceeding the capacity of storage bins and fine and coarse aggregates sloughing on to one another in the lower parts of the ' stockpiles. The licensee cleaned up the overspills; however, due to overfilling of storage bins, the sloughing problem will continue until stockpiles are reduced to less than bin capacity. Failure to stockpile aggregates as required by specifications is contrary to Criterion V of Appendix B to 10 CFR 50 and was identified to the licensee as Deficiency 491,492,493/78-08-01.

Inspection of the soils laboratory disclosed that sieves used for grain sieze analysis of (/ s '- soils and concrete aggregates are not checked in accordance with procedure and ASTM standards. Procedure M-26 and referenced ASTM D422 require that sieves used for grain size analysis conform to the requirements of ASTM Ell. Contrary to the above, discussions with responsible engineers indicated sieves used for grain size analysis , are not checked for conformance to ASTM Ell. Failure to check sieves - j as required by procedure is contrary to Criterion V of Appendix B to 10
