NRC STAFF TESTIMONY OF JOSEPH KANE ON STAMIRIS CONTENTION 4.3.
Q.1. Please state your name and position with the NRC.
A.
My name is Joseph Kane.
I am a Principal Geotechnical Engineer within the Hydrologic and Geotechnical Engineering Branch, Division of Engineering, Office of Nuclear Reactor Regulation, U.S. Nuclear Regulatory Commission.
Q.2 Have you prepared a statement of professional qualifications?
A.
Yes. See Attachment 1.
Q.3. Please state the duration and nature of your responsibilities with
-respect to the Midland Plant, Units 1 and 2.
A.
I have served since November 1979 as the technical monitor for the Midland portion of an interagency contractual agreement between the NRC and the U.S. Army Corps of Engineers, Detroit District (hereafter the Corps). By this contract the Corps has been assisting the NRC Staff in the safety review of the Midland Project in the field of geotechnical engineering.
In addition to, and as a consequence of, my serving as contract technical monitor, I have become directly involved in the assessment of the adequacy of the 8107240491 810723 PDR ADOCK 05000329 T
remedial measures which have been proposed by CPC to correct the plant fill settlement problem.
4 4. Please state the purpose of this testimony.
A.
The purpose of this testimony is to provide the NRC Staff response to Stamiris Contention 4.B.
Stamiris Contention 4.B. reads as follows:
Consumers Power Company performed and proposed remedial actions regarding soils settlement that are inadequate as presented because:
A....
B.
Slope stability of cooling pond dikes is not assured because they were built with the same improper soils and procedures (NCR QF172);
C....
D....
Therefore, unless all the issues set forth in this contention are adequately resolved, the licensee actions in question should not be considered an acceptable remediation of soil settlement problems.
Q.5. What is the NRC Staff response to Stamiris Contention 4.B?
A.
During the safety review of the Midland project, after it was realized that the main cause of the pl;.nt fill settlement problem was due to inadequate compaction of the soil materials, we reevaluated the adequacy of the dikes associated with the emergency cooling water reservoir (ECWR). Our concern was to obtain reasonable assurance that the slope stability of these dikes was adequate for the operation of the ECWR.
The major question requiring resolution was whether the soil materials in the dikes had been properly compacted to a deo'.'ty that assured needed shear strength properties under the various loading conditions which could
be anticipated to be imposed during the years of plant operation.
Settlement of the dikes was not the major concern.
Q.6. What portions of the cooling pond are considered to be seismic Category I structures?
A.
The two 30-inch diameter emergency discharge line conduits which exit the service water pump structure as shown on Attachment 2 are Category I.
In addition the Emergency Cooling Water Reservoir (ECWR) identified on Attachments 2 and 3 which was excavated in the natural soils, in the northeast corner of the much larger cooling pond, is also Category I.
In the event of a failure of the cooling pond dikes and loss of the larger cooling pond reservoir, the ECWR has been designed to contain a sufficient volume of water for a 30-day period without makeup. The ECWR provides water for shut down and cool down of the reactor and for mitigation of accident conditions.
Because a failure of the dikes adjacent to ECWR could potentially adversely affect the function of the Category I emergency discharge conduits and the emergency cooling water reservoir, the NRC has required that the stability of these dikes be adequately demonstrated through additional boring investigations and laboratory testing.
Investigation of potential sliding surfaces of the dike slope where it could potentially disrupt the discharge line are illustrated on Attachment 3.
4-1 y.7. Has the issue of the stability of these dikes been resolved?
A.
Separate testimony prepared by NRC consultant, Hari Singh, from the U.S. Arqy Corps of Engineers, addresses the concern expressed in Starairis Contention 4.B.

.lo nph D. Kane PROFESSIONAL EXPERIENCE SUfW.RY:
In NRC Division of Engineering, Geotechnical Engineering 1975 to Present Section, Mi'. Kane has specialized in soil mechanics and founde. tion engineering. Experiences in this position I
have included the following:
Evaluation of the foundation adequacy of proposed a.
sites for nuclear facilities with respect to design This work has included and operational safety.
evaluation of geotechnical, soils and rock mechanics, foundation and earthquake engineering related aspects.
The results of this review effort are summarized in a safety evaluation report for each of the proposed facilities which have included nuclear power plants, nuclear fuel reprocessing plants and uranium mill tailings waste systems.
Serving as a technical adviser for soil and foundation b.
engineering related aspects in the development of regulatory guides, acceptance and perfomance criteria that are intended to assure construction and operational safety of nuclear facilities.
Serving as a technical representative for the Office c.
of Nuclear Reactor Regulation on the NRC Advisory Group concerned with federal dam safety, Serving as an instructor for the Office of State d.
Programs in the training of state personnel who are responsible for construction and operational inspections of uranium mill tailings embankment i
retention systems.
During this period Mr. Kane was employed with the U.S.
1963 to 1975 Army Corps of Engineers, Philadelphia District and attained the position, Chief, Soils Design Section, Professional Foundations and Materials Branch, in 1973.
experiences with the Corps of Engineers have included l
the following:
The embankment and foundation design of four large multi-purpose earth and rockfill dams with appurtenant a.
l structures (spillways, inlet and outlet structures, l
control towers, flood protection facilities, etc.).
Responsibilities ranged from the initial planning of l
l
Professional Qualifications,
and Experience Joseph D. Kane subsurface investigations to select the most feasible sites through all design stages which were culminated in the final preparation of construction plans and specifications. This work included planning and evaluation of laboratory testing programs, studies on slope stability, seepage control and dewatering systems, settlement, bearing capacity, liquefaction, embankment safety instrumentation and slope protection.
b.
Served as a technical consultant to field offices charged with construction inspections for assuring completion of structures in compliance with design analysis and contract specifications. Participated in the development of needed modifications during construction whenever significant changed site conditions were uncovered.
c.
Lirteted the efforts of engineers in the Soils Design Section in other fields of civil work projects that included the embankment and foundation design of levees, waterfront pile supported structures and disposal basins for the retention of hydraulic dredge waste.
