iled in Section XI of the Code must be met for all Class 1 pressure-containing components (and their supports). The system boundary includes all pressure vessels, pip- ing, pumps, and valves which are part of the reactor coolant system, or connected to the reactor coolant system, up to and including: a. The outermost containment isolation valve in system piping that pene- trates the primary reactor containment. b. The second of two valves normally closed during normal reactor operation in system piping that does not penetrate primary reactor containment. c. The reactor coolant system safety and relief valves. 2. Accessibility The design and arrangement of system components are acceptable if adequate clearance is provided in accordance with IWA-1500, "Accessibility," of the Code. 3. Examination Categories and Methods The examination categories and methods specified in the SAR are acceptable if in agreement with the criteria in IWB-2000 of Section XI of the Code. Every area subject to examination should fall within one or more of the examination categories in IWB-2000 and must be examined at least to the extent specified. The methods of examination for the components and parts of the pressure-retaining boundaries are also listed in the requirements of IWB-2000 of Section XI of the Code. The applicant's or licensee's examination techniques and procedures used for PSI or ISI of the system are acceptable if in agreement with the follow- ing criteria: a. The methods, techniques, and procedures for visual, surface, or volume- tric examination are in accordance with IWA-2000 of Section XI of the Code. b. Alternative examination methods, combination of methods, or newly developed techniques to those given above in a. are acceptable pro- vided that the-results are equivalent or superior. The acceptance standards for these alternate methods are given in Section XI, 1WB-3000, "Acceptance Standards for Flaw Indications." 4. Inspection Intervals The required examinations and
