and the data given in the applicant’s technical submittal, and determines if sufficient investigation and testing have been carried out. If criteria are given, the staff reviews them to determine if they are appropriate and have been implemented. For structures with embedment substantially deeper than conventional nuclear power plants, the criteria used to determine the depth of borings, sampling and sampling disturbance evaluation, and laboratory and field test programs are reviewed to ensure that adequate depths and sampling intervals are utilized to establish the soil profile and the general engineering soil properties used in the site response and soil-structure interaction analyses. If it is the staff's judgment that the applicant's investigations or testing are inappropriate or insufficient, additional investigations likely will be required. The final conclusion is based on professional judgment, considering the complexity of the site subsurface conditions. As part of the review, the staff must ascertain, often with the help of consultants, that 2.5.4-9 Revision 5 – July 2014 state-of-the-art laboratory and field techniques and equipment are employed in determining the material properties.
