- 1) A summary M,
eootainment analysis including scaled lead platal A~
tabulation of computed stresses for various conditions;
- 3) Typical details of diagonal reinforcing (details en large opentmas are to be submitted lacer).
The deeign and analysis ef this conereto centaimmeet is based on a series of computer runs usind the fiaf.te element, direced stiffness, maisymmetric method.
M' J'f; in the program as required for the analysis were performed by the program developer, Dr. E. L. Wilson of the Daiver-sity of California.
On December 23, 1970, DRL requested adB,Lianal infomation on the matters addressed in Design geport No. 4, " Seismic Analysis of the Primary and gecondary Containmaat."
In a February 3,1971 letter, DEL summarises the status of design hiLeise identified at the public hearing areas in which more information or review is required include:
- 1) Structural design
- 2) Logic for auto depressurisation and rod block monitor systems
- 3) Spent fuel pool cooling system
- 4) Design basis for ESF's i
In addition to chsee items, CF&L was Frovided with criteria for contrcl of hydrogen and for the instrument lines penetrating containment.
No ACRS action seems warranted.
