This standard presents guidelines for evaluating site-related geotechnical parameters for nuclear power sites. Aspects considered include geology@ ground water@ foundation engineering@ and earthwork engineering. These guidelines identify the basic geotechnical parameters to be consicered in site evaluation@ and in the design@ construction@ and performance of foundations and earthwork aspects for nuclear power plants. Also included are tabulations of typical field and laboratory investigative methods useful in identifying geotechnical parameters. Those areas where interrelationships with other standards may exist are indicated.
