DOCKET NO. 50-312 The Rancho Suco construccisa site was visited on July 15-17, 1970 for the purpose of conducting a routine construction inspection. Observation of concrete placement had been planned, however, this was not possible since placement was held up pending resolution of the rebar spacing noncomformance which our inspector identified. Two other items of nonconformance involving weld electrode storage and Cadweld splice tests were noted. A proposed CDit has been submitted to CO HQ for all three items. It is our understanding that the licensee plans to take prompt corrective action on each of these O
deficiencies. We also feel that the separation of the inspectors from field engineering contract administration will most certainly enhance the quality control program and help to reduce these type of deficiencies.
You will note that the licensee has agreed to prepare some comparative samples of concrete for testing to demonstrate the validity of the current concrete placement test program. SMID has not agreed to go any g-'
further than point of placement sluey tests unless the comparative tests show a discrepancy. If we desire additional testing, it will require DEL correspondence with the licensee because the code in question (ASTM-C172),
is permissive in this respect.
The next inspection has been scheduled for the week of September 14, 1970.
Mr. W. Kelly of CO:II will assist on the inspection for the purpose of reviewing radiographs and welding of the containment liner plate.
