l AFFIDAVIT OF RAYMOND A. SULLIVAN AND ROBERT C. CHENG I
My name is Raymond A.
Sullivan.
My business address is 160 Chubb Avenue, Lyndhurst, N.J.
I am the Principal Civil Engineer responsible for Reactor Containment Building Design employed by Ebasco Services Incorporated.
The statement of my background and qualifications is attached as Exhibit I to this l
testimony.
My name is Robert C. Cheng.
My business address is 160 Chubb Avenue, Lyndhurst, N.J.
I am the Principal Civil Engineer responsible for Reactor Containment Building NSSS Interface employed by Ebasco S'ervices Incorporated.
The statement of my background and qualifications is attached as Exhibit II to this testimony.
The purpose of this affidavit is to address John Doherty's Contention No. 5 which alleges that the control rod
drive mechanism hydraulic control units (HCUs) and the transversing incore probe (TIP) may be damaged by the hydrodynamic forces of a high vertical water swell in the Suppression Pool folleving a loss of coolant accident (LOCA).
This affidavit addresses those portions om the contention which relate to matters within Ebasco Services Incorporated's design responsibility for the Allens Creek Nuclear Generating Station.
As the affidavit of Peter P.
Stancavage explains in considerable detail, General Electric Company has performed i
extensive tests to obtain information on the hydrodynamic loads that are generated in the area of the Mark III Suppression Pool during a LOCA.
HCU Platform The steel platform supporting the HCU Modules will be located above the height at which the General Electric Test Program indicates the largest LOCA induced bulk pool swell l
loads have terminated.
The HCUs will sit on a checkered steel plate floor 22 feet and 5 inches above the normal suppression pool surface.
This floor will be approximately half an inch l
1 thick and supported by floor beams spanning between wide-i l
flanged girders approximately 27 inches deep.
These girders i
will be supported frcm the drywell wall with no connection to l
the steel Concainment Vessel.
With this arrangement, the bottom cf the floor girders will be approximately 20 feet above :
l b'1 l
N i
the surface of the suppression pool where they will be inpacted' only by the froth impingement portion'of the LOCA loads determined by General Electric.
Top mounted trusses,will;be connected to the top of the girders in this region to" resist the, load from the froth impingement effect during LOCA.
_These trus'ses will also serve as supporting structures for'the.HCU modules against lateral seismic effect.
Vibratoryresponseofthesuphortplatformwill subsequently transmit a response load to thA HCU modules.
The magnitude of this response load for Allens Creek will be computed by Ebasco in a plant unique' dynamic analysis.
This response load will subsequently be utilized by General Electric in its dynamic qualification of the HCU modules.
Tip Platform The Tip Station will be located on a concrete plat-form cantilevering about 7 feet out from the drywell wall at an elevation of about 6 feet above the normal suppression pool surface.
To reduce the pool swell loads on this structure the
- u. p cantilever will be arranged thick enough so that the bottom surface is immersed into the pool; this bottom surface will also be sloped to function as a deflector.
Therefore, with this arrangement the platicrm will experience only the LOCA bubble pressure plus drag forces, and not'the bulk swell ispact. _
