Function of the VCC tiles is to provide a gap to mitigate trevice corrosion*at the base of the MSB. They are not structural supports for MSB nor VCC.

This analysis will consider; (I) the cond1tion that the VCC tiles may not b~ in full tontact with the MSB bottom plate, (2) and the shield ring assembly will be resting on top of the MSB.

<Inputs>

~SB 1o~d~d. dry weight = 63, 780 1bs* (Re~: 2. c. - Table 3. 2-1)

VCC Shield Ring = 1190 lbs (Ref. 4.c - Attachment 2)

Total Weight = 64970 lbs Tile Information:

Number of tiles = 24 (Ref. 2.a)

  • Size= 1.7 in. x 1.7 in. *x 0.3 in. (Ref. 2.a)

Area = 2.89 sq. in.

Minimum compressive strength= 30,000 psi. (Ref~-2.b)

<Calculation l>

Calculate stress on the tiles ~t full surface contact.with the *MsB bottom:

Load on each tile = 64970/24 = 2707 lbs Stress = 2707/2.89 = 936.7 psi 936.7 psi <<<< 30,000 psi min. compressive strength

<Calculation 2>

The MSB bottom may not be in full surface contact with the 24 VCC tiles due to the unevenness of the MSB bottom plate or VCC cask liner bottom. The 24 VCC tiles are equally placed on the 2 in. thick VCC bottom steel plate at 30 in.

radius: To be conserv~tive, all 24 tiles are considered to be partial contact of 1/8 in. by 1.7 in. per tile.

Calculate stress on the tiles with 1/8 in. partial contact:

<Calculation 3>

This calculation is to see* what is the minimum average contact area on the VCC tiles required* for ma i nta i ni ng the gap at the tile compressive strength* of 30,000 psi.

lri ad~ition, results are shown for the range of tile compressive strength given in tables of the Attachment 1.

If considered with Compressive strength values from the published reference books, even smaller contact area on the tiles is needed to perform the same function.

PALISADES NUCLEAR PLANT EA- SC-93-083-03 ANALYSIS CONTINUATION SHEET Sheet _4_ Rev # O Reference/Conment 6.0 CQNCLUSIONS The VCC tiles are capable'of providing the required gap to mitigate crevice corrosion at the bottom of the MSB for the following reasons:

a. The tiles used for Palisades VSC system are of porcelain ceramic and hav~ compressive strength equal to or greater than 30,000 psi used in this calculation.
b. Analysis approach is conservative by utilizing the lower limit of the tile strength and small contact area on all of .the 24 VCC tiles. * *

Subject:

Compressive Strength of Ceramic T'ale

Dear Mr. Zernick,

R~prding the subject of the compressive strength of the ceramic tile wed for supporting the ,, .

Multi-Assembly Basket(MSB) in the Ventilated Concrete ~k(VCC), I have researched SNCs files and contacted representatives of the ceramic industry for the following data:

SNCs Design Basis The input for the 2,000 psi ciush strength used for the design basis was obtained from the Ceramic Tile Institute. Typical crush strength of 2,SOO psi or* greater is required to resist typical

\ISe.* loam. SNC conservatively* used 2,000 psi.

  • MSB loaded dry weight = < 62,000 lbs VCC number of tiles = 24 ., ,

Size of tiles a 1. 75in1 .'

62,000/(1. 75)1

  • 24 = 843.S lbsfur < < 2,000 psi The tile is not an item important to safe~. The application of the tile is to provide cathodic isolation from the VCC liner. The tiles are installed 'level' to assure maximum contact with the MSB..The MSB is lowered.with great care into the VCC.
  • Ceramic Industry Data.

SNC contacted Jean Zwicker-QA Test Engineer for American Olean Tile Company. Ms.

Zwicker is currently developing an ASTM compre~ion test procedure for ceramic tile. The current American National S~dard Specification. for Ceramic Tile, ANSI A137.1, does not specify compressive strength. During the development of a compressive strength test, Ms.

Zwicker typically observed compressive strelJlth,s of 30,000 to 45,000 psi. for ceramic tiles meeting ANSI A137.1.

  • Attached published references &om engineering literature also indicate poroelan/ceramic compressive strength to S0,000 psi.

Conclusion Using the lowest observed *compressive strength value of 30,000 psi. one l.7Sin2 ceramic tile meetiIJ& ANSI A137.1, can support -90,000 lbs. During the installation of the MSB into the VCC, some spalling of the tiles initi~ contacted by the MSB may occur. Given the level imtallation of the tile, the MSB load will readily equalize over the remaining tiles .. The current VCC configuration utilizing twenty-four (24) tiles equally spaced in a level circle, shq.uld accommodate the MSB load with insigriificant tile degradation._ .

  • 1*hope *that tliiS documents the basis Qf _uti.~ the tiles for this application. Should you have any questions reprding SNCs conclusion please contact Kay Moeckel at 408/438-6444.
