ENCIDSURE
AGENDA
,
1.
Briefing by PG4B describing how the criteria in Sections 3.7
ard 3.10 of the FSAR were met.
2.
Presentation by PG4E of a list of seismic Category I equipnent
and structures with discussion of how they were qualified
and by whom.
Discussion of seismic design of turbine building and htake
3.
structure, including calculational results and data.
Includes
discussion of capabilities to withstand higher accelerations
than original design value of 0.4g.
4.
Discussion of floor response spectra resulting fium the 0.5g
carthquakes analyzed in December 1974.
Includes results at
frequencies higher than 20 Hertz, if available.
5.
Discussion of seismic Category I equipnent mounted on the
base slab or on ground. Type of qualification (test, static
analysis, single degree of freedom dynamic analysis, etc).
Comparison of the input spectrum usal for analysis or test
with the inpit spectrum resulting from the 0.5g carthquakes
analyzed in Decanber 1974.
ansede
6.
Review of detailed design data and calculations for reactor
coolant pumps, steam generators and supports for these components.
7.
Discussion of design control, measures to minimize and mitigate
errors, quality assurance and responsibility for design,
verification of codes, sensitivity of modeling techniques,
review of veniors' data and application of design codes.
, , . ,
Includes discussions with designers.
i
8.
Tour of Diablo Canyon plant to examine seismic Category I
equipnent which has been qualified by test or analysis
(primarily electrical equipnent).
9.
Discussion of possibility of containment liner bulge and
seismic capability of salt kuter cooling pipes, hot shut down
panel and main control board.
