Chief Executive Officer 245 St - Street Boston, Massachusetts 02107 Gentl -
This refers to the special inspection conducted by the NRC Office of Inspection and Enforcement at your facility on May 1-4, 1979, and to the discussions of our findings with you and the members of your staff at the conclusion of this inspection.
During the inspection, several instances were identified and documented in the enclosed inspection report where you failed to comply with NRC requirements.
The specific findings complete with reference to the applicable requirements are summarized in the enclosed Notice of Violation and Notice oi Deviation.
The main purpose of this inspection was to examine the measures which you have estaM.ished for the reporting of defects and noncompliances uncer Part 21 of Title 10, Chapter 1, Code of Federal Regulations and to verify,that these measures are being properly and effectively implemented.
In particular, your past actions relative to two specific technical issues presently the subject of an extensive, industry-wide analysis were selected for inspection. Your developcent and use of seismic computer codes with particular emphasis on the use of algebraic methods for intra-modal summations, and the design methods for pipe support plates using rigid body assu=ptions, were the specific issues chosen. Also examined during the inspection of your design for pipe support plates was your Quality Assurance program and its implementation relative to corrective action for significant deficiencies as required by Criterion XVI of 10 CFR 50, Appendix B.
Both of the technical issues selected clearly involve basic components important to nuclear facility safety and in both cases, defects in analyses or installa-tion hsve been identified by the industry-wide analysis currently underway.
h sed on current Commission actions, it is clear that a high potential did exist for these issues to be or to become substantial safety hazards, as defined under 10 CFR Part 21.
It is also clear that the Stone and Webster Engineering Corporation was involved in varying degrees in these issues and therefore under 10 CFR Part 21, shares the responsibility for assuring the appropriate evaluation and reporting of problems which are a substantial safety hazard.

Corporation We did not find during this inspection that the "responsi.f.e officer" knowingly or con-.
--'v failed to provide the notification requires by 10 CFR Part 21 in the c n reviewed. However, our inspectors found significant procedural deficiencies that impeded proper evaluation of such problems and passthrough of info =zation to the Stone and Webster responsible reporting officer. Because signifi ~ r safety matters with potential generic implications must be evaluated effectively and reported to NRC in a timely fashion, you are advised that proper corrective action must be taken promptly to comply with 10 CFR Part 21.
Please provide us within. 30 days of your receipt of this letter a written stat-e containing (1). description of the steps that have been taken or will be taken to correcc these items, (2) description of the steps that have been taken to prevent recurrence and (3) the date your corrective actions and preventive measures will be completed.
As a result of the specific identified deficiencies in your Part 21 evaluation and reporting procedures, we are concerned that the Commission may not have been adequately informed, as required by 10 CFR Part 21.21(b)(3), of those deviations that your company forwarded to NRC licensees for reporting under 10 CFR 50.55(e). You are therefore requested as a part of your corrective action, to reassess your past actions relative to those 50.55(e) reports and LERs submitted to the Commission by your clients after January 6,1978, for full conformance to Part 21 requirements. Should the results of your evaluations conclude that the Commission has not been adequately informed as required under Part 21, you are requested to provide in writing a statement addressing your corrective actions as noted above.
