CON 3OLTING ENGINEERING SERVICES 1114 CIVIL ENGINEERING BUILDING URBANA. ILLINOIS 618ol 21 February 1973 FINAL REPORT ON FINAL SAFETY ANALYSIS REPORT FOR ARKANS AS NUCLEAR ONE -- UN IT I ARK /NS AS POWER AND LIGHT COMPANY AEC Docket No. 50-313 by N. M. Newmark and W. J . Hall After our review of the FSAR, including Amendments through 29, we believe that the design of the Arkansas Nuclear One -- Unit 1 plant can be considered adequate in terms of provisions for safe shutdown and containment for a Design Basis Earthquake of 0.20g transient maximum horizontal ground acceleration and capable otherwise of withstanding the effects of an Operating Basis Earthquake of half this intensity.

Our review was based on consideration of the design criteria and resul ts of analysis as presented by the applicant in the FSAR and the answers to questions accompanying the FSAR for the site foundations, dynamic analysis of reactor buildings and other Class I structures, piping, vertical earthquake excitation, buried piping, stress limits, Class i equipment in Class li s tructures , reactor internals, cri tical items of control and instrumentation,

. penetrations , and the design of the reactor l ining.

~ The procedures-employed in the design as described in the FSAR are

' in accordanc'e with'.. the state-of-the-a rt. We believe that the design will incorporate an acceptable _ range of margins of safety to resist the design seismic hazard considered.
