Subject:
Additional Information in Support of SEP Topic II-4.F, Settlement of Foundations and Buried Equipment
References:

Dear Sir:
Reference (b) contains our assessment of SEP Topic II-4.F, Settlement of Foundations and Buried Equipment, for the Yankee Plant at Rowe, Massachusetts. We concluded that because the plant was founded on very dense glacial till and because no detrimental effects of differential settlement had been noted in the 23 years since beginning of construction, settlement of foundations and buried equipment is not a safety problem at Yankee. We reaffirm this assessment.
There is no reason to believe that groundwater and foundation conditions have changed in 23 years.
Therefore, any significant settlement of equipment and foundations would have already occurred and manifested itself.
Reference (c) requests further information in support of our conclusion that settlement of foundations and buried equipment is not a safety problem at Yankee. Much of the information requested is not available.
However, the following letters, reports, and boring logs are provided which give detailed information on foundation design, soil types, groundwater level, and j
liquifaction potential:
