Dear Colonel Friedenwald:
SubjectE Tnteragency Agreement (IA) No. NRC-03-82-107 Work Order No. One ('
When signed by the Corps of Eng,ineers (COE), this Work Order No. One (1) becomes effective under Article II entitled " Procedures for Placing Work Orders under this Agreement" of the subject IA.
The C0E shall acknowledge receipt of this Work Order No. One (1) immediately returning to the Nuclear Regulatory Commission (NRC) a copy of this letter signed below.
The COE shall perform the effort specified in Article I of the IA entitled " Statement of Work."
See Attachment A for described require-ments under this Task Order.
The level of effort is estimated at 0.1.5 staff-years over a 5-month period of performance.
Total charges under this Work Order No. One (1) are estimated at
$15,000.00 pending receipt of a proposal from the COE and subject to negotiation of the proposed costs.
The COE shall notify the Contracting Officer within 30 calendar days after receipt of this Work Order.

Earth Dam !!otion due to a !; car-field Eastern Earthqucke (V.C. Su.ner Review)
Project Manager:
L. Heller, FTS 492-8141 Background and Objective A number of nuclear power plants, some in the Eastern part of the United States, use earthern dams or embankments to impound water for operational safe-shutdown purposes.
Many of these_impoundements have induced some significant seismic activities.
For example, at the. Summer riuclear Power i
Station, series of reservoir induced seismicities have been observed since 1978 with the maximum acceleration as high as 0.34.
A practical under-9 standing of such earthquake induced motions is necessary to an evaluation.
of dam performance, functionality and safety.
Until recently, there have been no known. strong motion records of earth dam motion caused by near-field Eastern ~darthquakes.
On January 12, 1982, a Richter Magnitude 4.8 earthquake occurred in flew Hampshire.
Strong-motion records on a Corps of Engineer dam at Franklin Falls were obtained.
This dam is only 8 km. from the earthquake epicenter.
To support nuclear power plant licensing decisions on the Sumner TJuclear Power Plant, the Gcotechnical Engineering.Section, HGEB/DE/f;RR, needs a prompt interpretation of the unique strong motion records obtained at the Corps Franklin Falls dam.
This interpretation is required for the HGEB evaluation of the integrity of the dam at the Summer t;uclear Power Plant Site.
The following work requirements will provide the needed information.
