O ~ Docket No.
50-458/80-05 APPENDIX A NOTICE OF VIOLATION Based on the results of the NRC inspection conducted May 27-30 and June 2-5, 1980, it appears certain s. your activities were not conducted in full compliance with the conditions of yo-NRC Construction Permit No. CPPR-145 as indicated below:
A.
Failure to Follow Procedures for the Certification of Field Quality Control (FQC) Inspection Personnel Criterion V of Appendix B to 10 CFR 50 requires that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances, and shall be accomplished in accordance with these procedures.
The Stone and Webster Procedure, QAD-2.5, Revision C, " Qualification and Certification of Personnel Performing Quality Assurance Activities," requires, in Section 4.2.5, a certificate of qualification for each individual who verifies conformance of work activities affecting quality.
Each certificate shall include the activity in which the individual is qualified to perform.
Contrary to the above:
On May 28, 1980,. during a review of certificates of qualification of approxi-mately forty FQC inspectors, the IE inspector discovered that all of the individuals were certified to a specific level of capability within a specific function (inspection, examination, and/or test); however, the specific activity or task for which certified was not included in any of the certificates of qualification reviewed as required by the Procedure QAD-2.5, Revision C.
This is an infraction.
B.
Failure to Follow Site Procedures for Utilization of Qualified Inspection Personnel for the Performance of Site Inspection Activities Criterion V of Appendix B to 10 CFR 50 requires that activities affecting quality shall be prescribed by documcated procedures and instructions of a type appropriate to the circumstances, and shall be accomplished in accordance with these procedures.
1.
The Stone and Webster Procedure QCI-FRI-D.2.5-010, " Indoctrination and Training of Field Quality Control Personnel," specifically restricts, in Section 6.0, the use of personnel with lower levels of capability from performing activities in the higher levels of capability.
8 0 0818 0 5j[$
2.
The Stone and Webster Procedure QAD-2.5, Revision C, " Qualification and Certification of Personnel Performing Quality Assurance Activities," in Section 4.2, requires trainee personnel to work under the supervision of higher level personnel.
3..
The above Procedure QAD-2.5, Revision.C, in Section 4.3, further states that only personnel qualified at a Level II capability or at a Level III capability shall be considered capable of supervising or maintaining surveillance of personnel.
In addition,Section II of the inspection handbook, " Inspection Report System," requires that the reviewer should be an inspector other than the originating inspector, but at the same or higher level.
Contrary to the above:
On May 29, 1980, during a review of inspection reports, the IE inspector discovered the following:
1.
Review of concrete aggregate tests performed by the site FQC lab from January to March 1980 revealed that fifteen tests were performed by technicians (trainees) rather than by Level I or by Level II inspectors.
The test results were subsequently reviewed by technicians rather than by Level I or by Level II inspectors.
2.
Review of concrete aggregate tests and compressive strength tests of concrete cylinders performed by the site FQC lab from January through March 1980 revealed that seven inspection reports were completed by technicians. The reports showed no evidence of any subsequent super-visory review, or that the. tests were performed under the supervision of higher level personnel.
3.
Review of concrete aggregate tests performed by the site FQC lab from January to March 1980 identified that six tests were performed by Level II inspection personnel; however, the test results were subse-quently reviewed by technicians, not by inspectors at the same or higher level tan the inspector performing the test.
This is an infraction.
C.
Failure to Meet Specification lequirements For the Qualification of No.
67 and No. 8 Coarse Aggregates Criterion V of Appendix B to 10 CFR 50 requires that activities affecting quality shall be prescribed by documented procedures and instructions.
These procedures and instructions should include appropriate quantitative or qualitative acceptant; culteria for determining that important activities have been ratisfactorily accomplished.

1.
Stone and Webster Construction Specification 210.361, " Concrete Testing Services," requires that coarse aggregates be tested for compliance Jith ASTM C33, " Standard Specification for Concrete Aggregates." This includes testing the coarse aggregate in accordance with ASTM C117, " Standard Test Method for Materials Finer Than No. 200 (75-um) Sieve in Mineral Aggregates By Washing." AS11 C33, in-Table 3, " Limits for Deleterious Substances and Physical Property Requirements For Coarse Aggregates in Concrete," establishes the maximum limit for material finer than No. 200 sieve as 1.0%.
2.
Stone and Webster Construction Specification 210.350, "SpecificatAon for Mixing and Delivering Concrete," requires that coarse aggregates have a minimum specific gravity of 2.5 in a saturated-surface-dry condition. This requires that the aggregates be tested in accordance with ASTM C127, " Standard Test Method for Specific Gravity and Absorption of Coarse Aggregate." In addition, this specification requires that the concrete weigh at least 135 pounds per cubic foot (pcf).
Contrary to the above:
On June 4, 1980, the IE inspector discovered, during a review of N&D No.
9400 and N&D No. 9421 for the prequalification tests of No. 67 coarse aggregate and No. 8 coarse aggregate, the following:
1.
For No. 67 coarse aggregate, the ASTM C117 test results for material finer than No. 200 seive was reported as 1.8%.
This exceeded the maximum limit of 1.0%.
2.
For both the No. 67 coarse aggregate and the No. 8 coarse aggre-gate, the ASTM C127 test results indicated specific gravities of 2.48 and 2.49, respectively.
This was less than the specified 2.5.
Tests were performed with trial mixes to verify that the minimum concrete density of 135 pcf could be attained with these specific gravities; however, no data were available indicating that the minimum concrete density obtained with actual mixes used in Category 1 placements at the site was at least 135 pef.
This is an infraction.
