g Management Interview -- The results of the visit were discussed with Messrs. Mattimoe, Raasch and Stinchfield. Since no items of non-conformance were observed by the inspector, no commitments were proffered by the licensee. The inspector observed that it was not appropriate for him to comment on the QA program since it was still in the process of _ being formulated and was still subject to negotiation between SMUD and DRL.
Mr. Mattimoe stated that the QA program would conform with the new ' proposed criteria, Appendix B to 10 CFR 50.34.
Mr. Mattimoe also. stated that,.regardless, an adequate QA-QC program would be in effect at all times for all fabrication and construction activities.
DETAILS A.
Personnel Contacted Personnel conte.ted during the visit included the following:
SMUD John Mattimoe - Assistant Chief Engineer and Manager, Construction Dowell Raasch - Project' Engineer John ' Jackson ' - Quality Assurance Coordinator John Hiltz

- Quality Assurance Program The status of the quality assurance program for Rancho Seco was discussed with Messrs. Mattimoe, Raasch and Jackson.
Mr. Jackson was recently hired by SMUD as the quality Assurance Coordinator for Rancho Seco. He has nine years experience in quality control inspection manage-ment, primarily on the Polaris missile. For the past 2 years, Mr.
Jackson has been the Manager of Quality Systems for Aerojet General, Sacramento, California. This included Design Review, Quality Audit, and Quality Training groups. In all, his experience includes supervising Motor Processing and Inspection (170 inspectors);
Receiving Inspection for Polaris Setup, and Head of Inspection for Fabrication Machines. Prior to his quality control positions, Mr.
Jackson was a Test Engineer for Redstone and Jupiter missiles.
Mr. Jackson will be responsible for setting up the formal QA program for Rancho Seco. He will set up a documentation system to assure the f'""s retention of appropriate records
" pedigree for equipment and systems".
(d)
Inspection check lists will be followed for all phases of construction, including material receiving' inspections. A detailed inspection program N
will be' implemented for each phase in the construction process.
Mr.
Jackson stated that the QA program will have an " engineered documentation system".
According to Mr. Raasch, a rough draft of the program will be presented to DRL for comment early in July,1969. The finalized program will be presented to the Commission in the fonn of an amendment to the application by September 1, 1969.
While SMUD has the responsibility for QA, Mr. Mattimoe considers Bechtel as the Architect Engineer to be responsible for the QC inspection j
function of the nrogram.
Mr. M. Wilms will be Bechtel's quality assurance
. engineer at tF site. He is still at the Vernon, California office but will move to -ae site before the start of construction. Bechtel has already implemented a formal (p inspection program for SMUD. The Bechtel l
QC inspectors have begun making vendor inspections even though there has hardly been any equipment manufactured to date. The Bechtel inspection reports reviewed by the AEC inspector indicated that Babcock & Wilcox has been inspecting at the mills that are providing the steel for the steam generators and the. pressurizer. All nondestructive testing and mill certifications were reported to have been witnessed by a B & W inspector. The Bechtel inspector stated that he had reviewed mill test reports of tube sheets, plate, and nozzles for material checks of chemical analysis, physical description, charpy tests and ultrasonic tests. All'were reported to be in accordance with the requirements of the material.

h O(j As illustrated above, Mr. Stinchfield stated that Bechtel has a formal QC inspection program and has implemented it for the manufacturing of all components for Rancho Seco. However, Mr. Raasch stated that the program was still subject to review and approval by SMUD.
C.
Site Preparation The construction site was toured with Messrs. Raasch, Jackson, Hiltz and Blum. About 80-857. of the site preparation (excavation for major structures) work has been completed. All areas were being excavated to within a foot of final depth. The last foot will be left for the construction contractor who will be responsible for finished grading.
Mr. Blum stated that the soils at the site were found to be con-sistent with the results obtained from the core drillings. He stated that the allowable bearing load was at least 10,000 pounds per square foot, greater than the 9,000 pounds per square ' foot stated in the PSAR.
D. - Construction Schedule - Miscellaneous Mr. Mattimoe stated that the project was on schedule. The prime contractor for civil structures will be the combine of Leavell (Houston, Texas) and Dravo (New York City, New York). They had not yet moved onto the site but had set up a temporary office in Lodi, California.
The cement supplier had not yet been selected. A fully automatic batch plant will be constructed on the site and al1~ contractors will be required to use it.
In this way, SMUD will have control over the quality of all concrete that will be used at Rancho Seco.
It was expected that the batch plant would be constructed and testad by August 1, 1969. Concrete placement was expected to start aboct mid-August.
CB&I will supply the liner plate for the containment building.
Klinger, Stock Fabricators will be furnishing the structural steel and reinforcing bar. However, the supplier of the steel for Klinger, Stock Fabricators had not yet been selected.
-The permanent meterology tower has been installed and was expected to be in operation by June 9, 1969.
The deep well (400 feet) for the site has been drilled and was being tested at. the ~ time of the visit.
The temporary 3,000 KVA substation to be used for construction activities has been completed.
