h missiles. 2. Credible primary missiles including, valve hardware, retaining bolts, relief valves parts, instrument wells and reactor vessel seal rings (PWR). 3. Credible secondary missiles generated as a result of impact with primary missiles. Review Interfaces:10 The SPLB will coordinate with other branches' evaluations and reviews that interface with the overall review of this area as follows: review performed by the Structural Engineering Branch (SEB) is coordinated by the ASB and the results used to complete the overall ASB evaluation of the protection against internally generated missiles. 11 1. The Civil Engineering and Geosciences Branch SEB(ECGB) determines the 12 acceptability of the analytical procedures and criteria used for structures or barriers that protect the containment structure and liner, essential systems, and safety-related components from internally generated missiles as part of its primary review responsibility for SRP Section 3.5.3. The results of the review will be used to complete the overall SPLB evaluation of the protection against internally generated missiles. 13 2. The Mechanical Engineering Branch (EMEB) performs the review of dynamic effects associated with the postulated rupture of piping inside containment under SRP section 3.6.2. Typically included in SRP 3.6.2 is the review of any high-energy line spatial separation analyses performed by an applicant. The results of this review can be utilized to complete the overall SPLB evaluation of the protection against internally generated missiles.14 For those areas of review identified above as part of the review under other SRP sections, Tthe acceptance criteria and their methods of application are contained in the referenced SRP sections. 15 II. ACCEPTANCE CRITERIA Acceptability of the design information on protection of structures and essential systems and componentsSSC important to safety from internally generated missiles, as presented in the 16 applicant's safety analysis report
