eria The design limits imposed on the various parameters that serve to quantify the structural behavior of the containment are reviewed, specifically with respect to allowable stresses, DRAFT Rev. 2 - April 1996 3.8.2-6 strains, and gross deformations; with emphasis on the extent of compliance with subsection NE of the Code, Section III, Division 1; and with Regulatory Guide 1.57. For each specified load combination, the proposed allowable limits are compared with the acceptable limits delineated in subsection II.5 of this SRP section. Included in these allowable limits are the following major parameters: a. Primary stresses, including general membrane (P ), local membrane (P ), and m L bending (P ) plus local membrane stresses. b b. Primary and secondary stresses (Q). c. Peak stresses (F). d. Buckling criteria. 6. Materials, Quality Control, and Special Construction Techniques a. Information provided on the materials that are to be used in the construction of the steel containment is reviewed with emphasis on the extent of compliance with Article NE-2000 of Subsection NE of the Code, Section III, Division 1. Among the major materials reviewed are the following: (i) Steel plates used as shell components. (ii) Structural steel shapes used for stiffeners, beam seats, and crane brackets. Corrosion and corrosion protection procedures are reviewed by the Chemical Engineering Branch.14 b. The quality control program proposed for the fabrication and construction of the containment is reviewed with emphasis on the extent of compliance with Article NE-5000 of Subsection NE of the Code, Section III, Division 1, including the following: (i) Nondestructive examination of the materials, including tests to determine their physical properties. (ii) Welding procedures. (iii) Erection tolerances. Special construction techniques, if proposed, are reviewed on a case-by-case basis to determine their effects on the structural integrity of the completed containment. 7. Testing and
