T AUG 12 ggy Docket No.50-029 Mr. George Papanic, Jr.

Senior Project Engineer - Licensing Yankee Atomic Electric Company 1671 Worcester Street Framingham, Massachusetts 01701

SUBJECT:

YANKEE NUCLEAR POWER STATION - STRAIN DEPENDENT S0ll PARAMETERS The enclosed figure depicts the strain-dependent values for shear modulus and damping that the NRC intends to use for the comfirmatory seismic analysis of the primary auxiliary building at Yankee. In particular the staff plans to use the Shell data for the shear modulus ratio and the test data (D.J. Murphy et al.) for damping.

You are requested to review this infonnation and to provide your comments concerning the appropriateness of these parameters within 30 days of receipt

• of this letter.

The recording and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore OMB clearance is not required per P.L.96-511.
