contractors' inspections'and work procedures. These quality assurance reviews and approvals assisted in maintaining high quality for construction activities. The quality program at Millstone has identified quality problems early in the work process and has achieved timely and effective corrective actions and reinspection Throughout the years, Region I has received adequate responses from the applicant to inspector concerns. Further, it has been observed that the applicant has exercised strong control of the quality of the work by the major contractor,' Stone and Webster, and of subcontractor E. -The Millstone project has a three-level quality program concept as described belo The three-level construction verification program utilizes the defense-in-

. depth concept. The first level, QC inspection, is performed by Stone and Webster Field Quality Control, which is independent from the construction forces. Quality Control 'is responsible for verifying that the product meets the specified design requirements. The second level, QA auditing, is performed by Stone and Webster's Quality Assurance. Auditing Division, which is independent from the construction forces and Quality Contro The third level, Construction QA, is a section within the NU Quality Assurance Branch, which is entirely independent from all Stone and Webster organiz'ation Construction QA audits, performs surveillances, and makes in process veri-fications to assure that the quality programs of the first and second level organizations function as required. In addition, NU reviews specifications, site procedures, and other required documents furnished by Stone and Webster to assure that quality requirements have been incorporate The Quality Assurance organization is staffed with highly qualified per-sonnel. The staff consists of graduate engineers with several years of engineering or nuclear -industry experience, graduate technical scientists or technologists with several years of nuclear industry experience, and non-degreed technicians with. several years of nuclear experience. Several of the key individuals are additionally SNT-TC-1A certified, ASNI N45. inspectors, ASME VT 1 through 4 certified, or have been previously licensed at a nuclear facility. This quality organization is functionally and admin-istratively independent of the Millstone 3 project organizatio The organization remains in close contact with the NU engineering departments for consultation and technical assistance when neede .

To date, Northeast Utilities Construction Quality Assurance personnel have, conducted over 450 audits. These have confirmed that the first two levels of the quality program are working effectivel Northeast Utilities Service Company also audits the corrective actions on problems identified by S&W Quality Assurance audit reports. Additionally, Nonconformance. Reports having a "Use-As-Is" or " Repair" disposition are sent to NUSCo Construction Quality Assurance for review and concurrenc If there are any questions about any item in the S&W reports, the NUSCo Construction Quality Assurance Organization-takes investigative actio This has been effective in assuring Northeast Utilities management that S&W corrective actions are satisfactor The quality ~ assurance'. program implementation at the Millstone 3 station is also subject to review and/or verification by five independent outside organizations:

Stone and Webster Construction, Inc. has received and maintained its ASME

.. certification to install nuclear pressure retaining components. ASME teams audit every three years, with welding being one of the major areas covere National Board of Boiler and Pressure Vessel Inspectors Members of the Board participate in the ASME surveys and in the decision to grant the certificate. In addition, members of the National Board certify the Authorized Nuclear Inspectors who perform the ANI inspections described belo Hartford Steam Boiler Inspection and Insurance Company Hartford maintains a staff of Authorized Nuclear Inspectors (ANIS)

Northeast Utilities has been a participating member in a Joint Utility Management Audit Group since the early 1980s. This group manually audits-Northeast Utilities' activities. The JUMA audits of Northeast Utilities are conducted by senior supervisory quality assurance personnel from other utilitie .

The INPO Construction Project Evaluation was developed as a standard method of evaluating Utilities' nuclear construction program ._ __

Enclosure 2 4 Northeast Utilities supports the INPO CPE and has actively partici-pated in the development and trial of the Phase I evaluatio The above organizations evaluations, auditing, and verifications of the project have all been positive. The ASME audits have resulted in the extension of S&W ASME Certification of Authorization. The onsite Authori-zed Nuclear Inspector has verified the ASME work is done in accordance with the Code requirements. The semi-annual audits by Hartford have not identified a major problem. JUMA audits and INP0 evalu~ations have con-cluded that the Millstone 3 QA program is effective and is being effec-tively implemente INP0 evaluations and JUMA audits go beyond verifying conformance with established programs and make recommendations for improvements. Northeast Utilities has evaluated the INPO and JUMA recommendations and has adopted many of them. The results of these outside agencies' evaluations and audits have been beneficial. They have reported to the Company's manage-ment from a different perspective. This has further increased the con-fidence the company has in its quality assurance program which, in turn, leads to a higher degree of confidence in qualit The Northeast Utilities Quality Assurance Section has the. authority to stop work independent of the Construction organization and has not shown'a reluc-tance to do so when conditions warrant this action. The following summarizes stop work ~ actions. initiated by Northeast Utilities Construction Quality As-surance Organization:
