PALISADES REQUEST FOR ADDITIONAL INFORMATION STRUCTURAL TOPICS a
Additional information 'is needed for the following structural topics:
III-2 Wind and Tornado Loads For each safety-related structure, describe the procedures to transfer tornado data into design pressure.
III-7.8 Design Codes, Desion Criteria and Load Combinations 1.
With regard to the design of the prestressed concrete containment, provide the design specification and any design reports. This information should include those requested in items two, through five below.
2.
List the codes and standards (include edition date) used for design and construction of steel members of each safety-related structure.
3.
List all loads considered in the design of safety-related structures including any missile or pipe break effects.
4.
Provide the design and/or actual material properties (fg and fi) used for steel and concrete elements.
For concrete, also provide the age specified and any admixtures used.
5.
Provide representative stress levels (conpression, tension and shear) at critical location of each safety-related structures (e.g. base of containment internal structures) for each of the load combinations considered in the design.
III-7.C Delamination of Prestressed Concrete Containment Structures Describe the construction procedures for the prestressed containment shell including the tendon tensioning sequence.
Provide any inspection reports for the containment that may have assessed the likelihood of delamination occurring in the shell wall or dome.
If such inspections were made but not documented, describe the results of these inspections.
III-7.0 Containment Structural Integrity Tests Provide any reports that describe the procedures and results of the containment structural integrity test.
