SUBJECT:
THREE MILE ISLAND NUCLEAR STATION U'iITS 1 AND 2 DOCKET NOS. 50-289 AND 50-320 QUALITY ASSURANCE PROGRAM
Dear Mr. O'Reilly:
Our letter dated November 3,1972, described the actions we are taking to resolve each finding reported in AEC/DRO letter of October 6,1972, which contained findings based on an AEC/DRO audit of the Three Mile Island construc-tion site.
In our eceting of November 9,1972 in your office in Newark, we agreed that we would supplement our November 3,1972 letter to describe the general corrective measures we have taken with regard to compliance with QA/QC requirements at the Three Fule Island site.
These general corrective measures can be summarized as follows:
1.
Indoctrination and training programs were instituted in September 1972 for all UE&C site quality control personnel and for appropriate UE&C construction supervision. These training programs are directed towards assuring that UE&C personnel performing work on nuclear parts of the plant fully understand the requirements of construction and quality control procedures. New UE&C personnel will be given equivalent training and indoctrination.
This requirement for training and indoctrination of personnel will be incorporated in appropriate construction and quality control procedures by January 15, 1973.
2.
UE&C has assigned a senior individual to a position where his main responsibilities are to (a) ensure that UESC construction supervision understands and. implements quality control requirements, and (b) ensure that UE&C construction rapidly and satisfactorily resolves deficiency reports, audit findings, and similar reports of non-conformances. This individual has authority equivalent to the site superintendent reporting directly to the UE&C project manager, and is the UESC representative on the Deficiency Review Board.

, 3.
The UE&C site procedures for control of nonconforming conditions (QC-17 and QC-17-2) were revised in August 1972 to emphasize that any nonconforming work must be stopped without delay.
4.
Effective October 31, 1972, GPUSC has taken over management direction of the UESC site QC organization. The head of the former UE&C QC group for the Three Mile Island project is now the GPUSC TMI QA Manager and reports directly to the GPUSC Manager of Quality Assurance.
It is considered that GPUSC management of the QC organization will assure that UE&C QA and construction personnel understand and comply with CPUSC's requirements for strict compliance with all QA/QC requirements in procedures, specifications, SAR's, etc..
Since taking over management of the UE&C site QC organization, it has been emphasized again to site QC personnel that no deviations are permitted from QA/QC requirements, and any nonconformances which are detected must be controlled in accordance with the applicable QC procedures (QC-17 and QC-17-2).
5.
In August 1972, GPUSC established a special surveillance group of about ten engineers to monitor UESC construction activities at the site and assure compliance with QA/QC requirements. A further function of this group was to help make.sure that the UESC site QC personnel whose activities they monitored had a satisfactory understanding uf all applicable requirements. We consider this special group to have served its purpose, and that site performance has improved. With GPUSC taking over management direction, we have retained at the site several of the engineers from the group as QC engineers reporting to the GPUSC Three Fule Island QA Manager.
These engineers, and other new engineers we are assigning, will aid in the review of documenta-tion, preparation of procedures, resolution of problems, etc..
6.
In conjunction with CPUSC taking over management direction, the duties of the GPUSC site QA group have been redefined to emphasize.their auditing function. The CPUSC site QA representative 's title has been changed to CPUSC Site QA Auditor. Most of his former administrative duties, for example, review of construction procedures, have been transferred to the CPUSC TMI QA Manager.
It is considered that this realignment of responsibilities will permit the CPUSC Site QA Auditor to perform more frequent and effective audits. The GPUSC Site QA Auditor will make use of consultants as necessary to assure that important aspects of site operations are audited.
7.
'The President of UE&C established an Executive Task Force on September 5,1972, with the objective of independently investigating all facets of the project, including the quality control effort, and making recommendations where appropriate back to the President.
8.
In order to achieve a more favorable supervision to craf t ratio, the manual craft labor force is being reduced by 20% in the months of November and December 1972. This will tend to exert more effective supervision and control over the work.

Our letter of November 3,1972, also indicated that we would advise you of the final resolution of two iters regarding Grinnell pipe welds. One item, which was discussed in paragraph 3.b of enclosure (1) to our letter, involved low ferrite content in soue stainless steel welds. The second item, which was discussed in paragraph 19 of enclosure (2) to our letter, involved excessive weld weaves. Grinnell has informed our representatives that they consider both of these conditions to be acceptable. Our technical evaluation is continuing and is not yet cocple t e. We expect to have it complete by January 31, 1973, and will advise you of our conclusions at that time.
Very truly yours, I
