ENCLOSURE Summary of Tentative Conclusions Recarding Concerns Raised by

' l. Concern: Concrete test cylinders with adequate strength were used tc represent other placements (AQC-ll).

In the absence of specific details as to which placements this alleged incident pertains to, the TRT (Technical Review Team) could not make a specific investigation of the allegation. When sample cylinders were tested, at most two extra cylinders remained for which the test results could be switched to the testing data for other placements. Therefore, even if data were improperly transferred, the significance would be small because of the consistently high quality of the concrete placed at Comanche Peak.

2. Concern: No reinforcing steel was placed around a 24 inch diameter pipe (an approximate 6' x 6' wall area) in a structure near the Squaw Creek Dam Spillway (AC-30)

The TRT inspected the structures near the Squaw Creek Dam Spillway and found two structures with a 2 to 3-foot diameter pipe surrounded by reinforced con-crete. One of them was the outlet works conduit section; the other was the return pump station. The TRT concluded your allegation concerned the return pump station based on your employment period. There are two 24 inch diameter steel pipes in the return pump station which pass througn a concrete wall. The TRT examined the concrete placement card for the walls of the return pump station. It contained the required two signatures certifying that the reinforcement was correctly placed prior to concrete place ent.

It may also be noted that when the reservoir was filled by pumping through the large pipe, the concrete wall was subjected for an extended oeriod of time to the highest static load to which it will ever be subjected. It performed without distress.

3. Concern: A spillway pillar span, or column was erected 75 degrees to 80 degrees offset (AC-29).

The TRT learned in an interview with you that the structure referred to was located in the Service Outlet Structure below the Squaw Creek Dam Spillway.

The TRT inspected the service outlet structure and found no evidence of any spillway pillar, span, or column which was erected 75 to 80 degrees offset.

The general configuration of the structure was consistent with that shown on the design drawings.

4. Concern: Fresh concrete was placed on top of crumbling concrete during the construction of the spillway. (AC-28).

There are two spillways at Comanche Peak, one located near the safe shutdown impoundment (SSI), and the other located at the Squaw Creek Dam. The SSI Spillway was eliminated because it was constructed after the period stated in your allegation. A review of placement documentation indicated that the Squaw Creek Dam Spillway was placed in a single lift, therefore, no new concrete could have been placed on hardened or crumoled concrete.

L

s

-g-a The TRT learned in an interview with you that you were more generally con-cerned with the adequacy of cold weather placement practices during con-struction of the Squaw Creek Dam and appurtenant structures. However, you were unable to identify a specific spot where specifications were violated.

The TRT examined documentation for cold weather protection for several place-ments during its investigations of other allegations.' Those examinations con-firmed that cold weather protection was adequate. Furthermore, the Squaw Creek Dam is not. a Seismic Category I structure which means that its failure would not affect safety during a safe shutdown earthquake.

tha t r-f- " buy off" on the night shift's work. Eventually told the nicht shift (
inspectors tos"lcasen up" on our inspections, or I'll start getting' rid 'of hch of yot one by one." After this meeting my crew asked me what they should do. I told them to i

ao whatever they thought they should do to p"otect their jobs, but that "if they let

up on their inspections, I'd fire them myself." I believe the NCRs decreased in

[ numoer for a while. I do not believe this incident was included in my testimcny

before the ASLS.

" own & Root, I was approached by CASE who I crovided a statement. I was later

. apoenaed to the ASL5 hearings where I testified as a reluctant witness. I believe i

.. at my testimony before the ASLS and my problems with CASE led to my ceine , 3

" blackballed" in the nuclear industry. At the time I was ha ced, successfully avoided being subpoenaed % ,

During an earlier telephonic conversation on this matter with Investigator GRIFFIN, I elected to enter into a confidentiality agreement with the NRC. In light of a recent newspaper article which indicated that the ASLB for Comanche Peak was planning to examine my ^ termination by Brown & Root, I have decided to release the NRC from the confidentiality agreement so the that incident can be thoroughly analyzed and discussed as needed by the NRC.
