OYSTER CREEK # 2 - CDNSUllW* TTS' STELUrtEAL QUSSTIONS Atta&J is a list of questions taken from dy. Nlwmark's report on Oystei Creek #2.
Sona aspects have aircady been taken care of in our basic question list. These additienal questices nay be incorporated as a gror.p in a new Section 6.0, or indivicually in applicabl.e areas of the basic question list, as desired.

Indicates optional question location in general questica package.
6.1 Indicate tha vnricus f oundation levels with regard to existin; grace.
(1.9) finished grade, and the underlying soil strata. Also provide a discussics of tne potential for liquef acticn under the various structural foundations.
5.2 For the containment seismic design, as well as Class I equipcent and (2.4(d) ite::.s such as piping, describe the nethods fer conputing code shapes, frequencies and participatica f actors, and the =ethods for conbinin; the modal values tc obtain the design val:.es of acceleraticn, s haar,
nonent, etc.
(2.4(e)
If seiJMic Coef ficients are to be used for design in place of normal modal calysis procedures, explain the basis for selection of the coefficients and their application.
6.3 State whether earthquais stresses will be added linearly and directly (2.4 (f )
to the other applicabla stresses.
6.4 thder the f actored load design, will the load capacity be lizited to (2.1(i) yield or below? If the total stress exceeds yield, describe the criteria amployed to ensure that stresses and defcrmations are limited.
6.5 Provide Icading combinations for which the piping is to be designed and (1.10) the stress and strais criteris applied for earthquake loadings.
6.6 For the prestressing tendons, give strand details, showin; the nunter of (2.1(j) strands ps.r tendon. Also provide approxinate dimensions and spacings of anchorage zones both through the wall thickness and along the circunfer-ence of the structure.
6.7 Describe functionally the side gallery (not the prestressing gallery)
(1.12) located above the foundation slab to about grade.
6.3 Provide an organization chart for quality control and quality assurance (4.16 )
showing the lines of responsibilityforthe organizaticns and critical perscnnel involved.

Js,
, s 2-6.9 Describe design criteria which ensure that critical controls, (1.11) instrumentation, batteries, etc. will eterate properly to provida saf e shutdown under seismie or other cesign loads.
6.10 Give tha cesign criteria for desir,n of the ccoling vatar intaha (1.13) structures and associated piping critical to the saf e snutdown c' the plant under seisaic, hurricane or high water ccnditicas.
6.11 Consistency of design with the 0.22; earthquake would indicate that (l. i3 )
Class 11 structures and equipoent be designec to 2/3 of the 'Jnif trn Building Code Icne 3 require =ents.
Indicate design criteria and details for Class II structures and cc=';ctants.
