tors contributing to the structural integrity of the reactor vessel and conclude there are no special considerations that make it necessary to consider potential reactor vessel failure for this plant. The bases for our conclusion are that the design, materials, fabrication, inspection, and quality assurance requirements for the plant will conform to applicable NRC regulations and regulatory guides, and to the rules of the ASME Boiler and Pressure Vessel Code, Section III. The stringent fracture toughness requirements of the regulations and ASME Code Section III will be met, including requirements for surveillance of vessel material properties throughout service life, in accordance with Appendix H of 10 CFR Part 50. Also, operating limitations on temperature and pres- sure will be established for this plant in accordance with Appendix G. "Protection Against Nonductile Failure," of ASME Code Section III, and Appendix G, 10 CFR Part 50. The integrity of the reactor vessel is assured because the vessel (1) will be designed and fabricated to the high standards of quality required by the ASME Boiler and Pressure Vessel Code and any pertinent Code Cases; (2) will be made from materials of controlled and demonstrated high quality; (3) will be subjected to extensive preservice inspection and testing to provide assurance that the vessel will not fail because of material or fabrication deficiencies; (4) will be operated under conditions and procedures and with protective devices that provide assurance that the reactor vessel design condi- tions will not be exceeded during normal reactor operation, maintenance, testing, and anticipated transients; (5) will be subjected to periodic inspection to demonstrate that the high initial quality of the reactor vessel has not deteriorated significantly under service conditions; (6) may be annealed to restore the material toughness properties if this becomes necessary; and 5.3.3-6 Rev. 1 - July 1981 - (7) will be subjected to surveillance
