( S'TATEh1ENT BY{ '. CllARLES ANDERSON, P. E., ESQ.'

before the Advisor, Committee ca Reactor Safeguards l Alay 20-21,1982 Soil / Structure Interaction Problems

1. Soil Settlement i

Foundation settlement consists primarily of two parts, primary and secondary settlement. Primary settlement is usually used for design in this country and secondary is ignored. Just the opposite is the practice in Europe.

These two parts of total settlement are often roughly about the same amount.

It appears that-in this case especially the Diesel Generator Building (DGB)-

secondary settlement has not been considered. I believe settlement for the DGB is not yet completed, but will continue for some years causing further stress and cracking to the building.

~

2. Structural Integrity .

The DGB is excessively cracked from differential settlement. This crack-ing will continue for some years. The structure cons'sts of roof girders spanning to bearing walls. These bearing walls provide a box structure; however, in the case of the DGB and the Service Water Building, the classical box structure has been modified in the roof, in the floor, and especially in some walls where the box stiffness of these walls has been greatly reduced by large structural holes and cracks. The stiffness of the structure has been largely lost leaving the building without the degree of rigidity that certain representatives of Consumers Power Company have told me is there. I assure you that it is not.

Both buildings lack structural integrity today. The settling, the cracking and the further loss of structural integrity can only continue.

STATEMENT DY DR. CHARLES ANDERSON, P.E., ESQ.

Before the Advisory C imittee on Reactor Safeguards

- May 20-21,1982 Addendum f' 1, May 20,1982

~

Consumers' 11:00 a.m., May 20,1982 statement, "Dr. Anderson mistook the second floor as the roof,"is not factually correct nor is it relevant to ,

the contention ". . . stiffness of the structure has been largely lost. . ." in the first paragraph of section " Structural Integrity". The " box stiffness" referred to by me on May 20, 1982 as being reduced is in fact due, in part, to the horizontal structural plates at the t6p of the building.

It is my contention that Consumers' statement is either incompetent or

• intentionally malicious.

( STATEMENT BY DR. d .IlLES ANDERSON, P.E., ESQ, Before the Advisory Committee on Heactor Safeguards

,. May 20-21,1982 Addendum # 2, May 21.1982 After 3 days of being jerked around and lied to by Consumers Power Co.,

having been denied requested access to the Midland site, having had Consumers distort my May 20, 1982 statements before the ACBS, realizing fully Consumers general lack of good faith in their desperate situation, it is time to draw the bottom line on the Diesel Generator Building:

. Consumers erred in the placement of the fill.

. Dr. Peck erred in the pre-loading of the fill with the DGB already ,

constructed. As a result, the structure has cracked extensively, and yet secondary settlement has not been arrested.

. The building has lost its essential structural integrity and is now exposed to continued settlement and additional structural cracking.

1

. The function of the building apparently cannot be changed and is critical to the site. .

. The building cannot reasonably be made to structurally satisfy its critical function considering the troublesome site history.

. The building can only be replaced to resolve the problem of public s afety.
