Dear Mr.- Campbell:
SUBJECT:
SEISMIC DESIGN AND-TORNADO PROTECTION OF
-THE CONDENSATE. STORAGE TANK,'ANO-1
')
On April 7 and 8, 1987, a site visit was conducted by the NRC staff and _. ,
consultants as part of the review of the subject design. In order to complete i t the review we will'need the information identified in the enclosed trip . .
report. Please provide your responses within 60 days of the date of this !
letter.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore, 0MB clearance is not required under P.' L.96-511.
Sincerely, i

. reviewed during the visit: I 1, Calc #82-0-2086-08 was performed by NUTECH under contract to APL.
The FLUSH computer code was used to coqute the seismic response of I
the tank / caisson system. The results of this cogutation are design foundation response spectra for both the OBE and SSE earthquakes.

review of th'e soil data indicate that the clay is saturated. One would expect the Poisson's. ratio fc,r a saturated clay to be larger than'O.2.
- 3. :The motion developed from the criteria design. spectra was assumed at the surface and. deconvolution methods were used to calculate a consistent bedrock motion.. This bedrock motion was then used as input to the FLUSH program. Since the primary support of the tank (especially'for. vertical and rocking motions) is the caissons which are founded on bedrock, a. more consistent' application'of NRC guidelines would be.to use the criteria motion as input to the base of- the caissons (at bedrock).
- 4. A 10-secohd duration pulse was used as input to the FLUSH model.
1 Response spectra developed from the FLUSH results were then used by.
CBI 'to calculate the effects of water sloshing. :The frequency of the -
sloshing mass was calculated to be about 0.25 cps.. It_ is . questioned !
whether the input spectra, developed from a. ten-second duration pulse, is adequate to' evaluate the response of a 0.25 cps system.
- 5. Respons'e spectra were reported.at the foundation level. These spectra were then used by CBI to evaluate stresses in the tank. 'This ,
approach neglects any inertial that would occur as a result of
- rocking of the' tank. Some rational for_ neglecting this effect is required.
- 6. The CBI calculations do not seem to account for an increase in fluid pressure as a result of the verf.ical seismic input. This increase'in pressure would result in higher hoop stresses in the tank walls.
CBI calculates a wave neight due to sloshing effects which is hip..e l 7.

It is recommended that APL be requested to provide additional information on the above issues before an assessment of the tank design is conpleted.
