Commissariat a l'Energie Atomique l ISPN, DAS' CEN/FAR - B.P._No. 6 4 F - 92260 Fontenay-aux-Roses France :

Dear Dr. Schmitt:
I i Dr. B. 'Mohamadioun of the CEA staff,'his consultants, Dr. M. Bouchon and Mr. .
i A. Pecker, and Mr. L. Beratan, and Dr. A. Murphy of the NRC staff and their
! contractor, Dr. R. Archuleta,.recently visited Mammoth Lakes, California,'to i examine the ongoing experiment to measure down-hole propagation of seismic strong ground motion. The soil cover at Mammoth Lakes is a glacial-till.
r Because this soil cover is so non-typical.of alluvial soils, another site in ,
3 alluvial soil underlain by crystalline rock in.a seismically active-ared was
- sought. The area agreed upon for a second down-hole experiment was Anza, ,
- California, near the San Jacinto fault which is seismically very active. ~The 4 general area for the experiment has been identified, but the specific location j- with the required approvals for access.have not yet been obtained. ,
i i
It is proposed that two large diameter holes (6 or 7 inches) will be drilled, one to the top of the rock and one to a depth of 150 to 200 meters, the final' depth to be determined on site by Dr. Archuleta. A soil boring will be made so :'
- that an accurate profile can be determined. . Soil sampling will be made by the
- i. use of a 2 inch split spoon sampler. driven by a 140 pound weight having a free i fall of 30 inches. Samples will be taken.every 10 feet'or change in soil formation. Samples taken from the. sampler will be sealed in jars for later y analysis at the Corps of Engineers Waterways Experiment Station-in Vicksburg, 3 Mississippi. Three undisturbed Shelby tube samples will be obtained from each of three soil horizons for dynamic testing (nine Shelby tube samples). See i 3
enclosure for a testing program and costs. .This experimental work is.
considered essential to the true understanding of the wave. propagation from
- rock through the alluvial soil overburden. This type of experiment has not-
j been conducted elsewhere to our knowledge and should provide data to validate l
presently used' soil structure interaction models. 1 1
In accordance with the letter-of-understanding signed by Mr. R.B. Minogue, Director, Office of Puclear Regulatory Research, USNRC, on July 8. 1985, and-l l '

- Dr. F. Cogne, Directeur, de l'Institut de Protection et de Surete Nucleaire, on August 20, 1985,;the NRC would agree to pay for the instruments to be installed ;
in the bore holes and their installation.and the maintenance of.the program for ,
three years. The estimated cost to the NRC will be $60,000/ year over three i
years for a total cost of $180,000. .The estimated cost to the CEA for borings, i sampling, logging, soil testing, transportation and handling is estimated to be <
- $69,600 U.S. dollars (see enclosure for detailed estimate). Copies of all data
- from the experiment and testing will be given to the CEA for analysis by its I experts. A copy of all analyses perfonned on the data.by the CEA and its l experts will be furnished to the NRC.
. If this is agreeable to you, please indicate by your signature below and return l a copy to me. Work on this cooperative agreement can begin immediately there 6 after. (
