JOINT AFFIDAVIT OF KENNETH S. HERRING AND DREW PERSINKO ON PGE MOTION FOR
SUMMARY
DISPOSITION WITH REGARD TO CFSP CONTENTION 22 STATE OF MARYLAND
)SS COUNTY OF MONTGOMERY)
I, Kenneth S. Herring, being duly sworn, depose and state:
1.
I am a Senior Structural Engineer, Engineering Branch, Division of Operating Reactors, U.S. Nuclear Regulatory Commission, Washington, DC 20555.
2.
I have prepared the Statement of Professional Qualifications attached hereto, and if called upon, would testify as set forth therein.
3.
I have prime responsibility for that portion of the NRC Staff's review of the proposed modifications to the Trojan Control Building which deals with the structural adequacy of those proposed modifications to bring the facility into substantial compliance with the license.
I, Drew Persinko, being duly sworn, depose and state:

I have prepared the Statement of Professional Qualifications attached hereto, and, if called upon, would testify as set forth therein.
6.
I am responsible, along with Kenneth S. Herring, for that portion of the NRC Staff's review of the proposed modifications to the Trojan Control Building which deals with the structural adequacy of those proposed modificati,ns to bring the facility into substantial compli-ance with the license.
We, the affiants Kenneth S. Herring and Drew Persinko, being duly sworn, depose and state:
7.
Within the areas of our review responsibility, we are responsible for addressing CFSP Contention 22 which states:
22.
The effect of the steel plate on displacement in the Complex has not been completely analyzed.
8.
Within the scope of our review responsibilities, we have reviewed and evaluated the proposed modificatiers to the Trojan Control Building and the Licensee's analyses of those rodifications as well as the Affi-davit of Dr. William H. White on Ccalition for Safe Power's Contention No. 22.
9.
Based on these reviews, we make the statements set forth in paragraphs, 10 to 14 as follows.
10.
We agree with. paragraph 5 of Dr. White's affidavit.
11.
We agree with paragraph 6 of Dr. White's affidavit and this was addressed under Phase I of the Control Building proceeding.
- 12.
The addition of the steel plates and three walls will stiffen the Complex in the N-S direction (parallel to the direction of the steel plate) and cause displacements to be less in the modified state of the Complex than in the unmodified state.
It was found that there was sufficient clear-ance between the Turbine and Control Buildings in the N-S direction as discussed under Phase I of the Control Building proceeding with a gap of 3 inches between buildings.
Therefore, the gap of 4 inches after the modifications should be adequate, although displacements are still not quanitfied due to the uncertainties with regard to stiffnesses used in the analyses as set forth in the Staff SER of February 14, 1980.
13.
In the E-W direction, it was shown under Phase I of the Control Building proceeding that a gap of 2 inches at El.99 feet was adequate to maintain clearance between the buildings with margin. The addition of walls and plates will not significantly stiffen the Complex in the E-W direction.
However, gaps of 2 inches at El.93 feet and 2.5 inches at El.69 feet should be adequate to preclude striking of the buildings. However, the displacements have not yet been quantified pending resolution of the concerns with regard to stiffnesses derived in the analyses as set forth in the Staff's SER.
14.
In both the E-W and N-S directions, maximum displacemengs and gaps provided are presented by the Licensee which indicate adequate clear-ances between buildings. We believe that it is not possible to concur with these displacements because of the unresolved items in the SER dealing with stiffnesses in the modified Complex. These items include the normal forces that affect stiffness which are determined by effects
. of gross overtuning, shrinkage, and temperature; single versus doubic curvature behavior; reinforcement ratios; and shear stresses. These effects can increase displacements beyond those shown in the affidavit of Dr. White.
