postulated LOCA and SSE and (for a BWR) the combined loads of a postulated MSL rupture and SSE. The analysis provides adequate assurance that the combined stresses and strains in the reactor internals will not exceed the allowable design stress and strain limits for the materials of construction and that the consequent deflections or displacements at any structural elements of the reactor internals will not distort the reactor internals geometry to the extent that core cooling may be impaired. The methods for component analysis have been found compatible with those for the systems analysis. The proposed combinations of component and system analyses are, therefore, acceptable. The assurance of structural integrity of the reactor internals under LOCA conditions for the most adverse postulated loading event adds confidence that the design will withstand a spectrum of lesser pipe breaks and seismic loading events. 5. The applicant has met the relevant requirements of GDC 1 for systems and components designed and tested to quality standards commensurate with the importance of the safety functions performed by the proposed program to correlate the test measurements with the analysis results. The program provides an acceptable basis for demonstrating the compatibility of the results from tests and analyses, the consistency between mathematical models used for different loadings, and the validity of the interpretation of the test and analysis results. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and
