practice for similar facilities. Site exploration, sampling, testing, and interpretation are judged with respect to completeness, care and technique, meaningful documentation, performance records for similar projects, published guidelines, and state-of-the-art practice. However, unconventional or research- oriented tests and interpretations are encouraged whenever such work aids or supplements conventional practices. Design criteria and methods are compared to similar standards published or utilized by public agencies such as the U.S. Navy Department, U.S. Army Engineers, and U.S. Department of the Interior. Design safety features, the applicant's proposed confirmatory tests and measurements, and monitoring of performance for safety-related foundations and earthworks are reviewed and evaluated on a case-by-case basis. Subsection 2.5.4.12. Techniques to improve subsurface conditions are evaluated by reviewing the applicant's specifications and techniques for performance and quality control for such activities as grouting, excavation and backfill, vibroflotation, rock bolting, and anchoring. Confirmatory data should be contained in the FSAR. 2.5.4-13 Rev. 2 - July 1981 IV. EVALUATION FINDINGS If the evaluation by the staff, on completion of the review of geotechnical engineering aspects of the plant site, confirms that the applicant has met the requirements of References 1 through 7 and the regulatory positions of References 8 through 11, the conclusion in the SER will state that the investigations performed at the site are adequate to justify the soil and rock characteristics used in the design, and that the design analyses contain adequate margins of safety for construction and operation of the subject nuclear power plant. Staff reserva- tions about any portion of the applicant's analyses will be stated in sufficient detail to make clear the precise nature of the staff concern. A typical staff SER finding follows: The site is located in the Piedmont at an average
