II.iERVIEW MEMORAtCUM ATS fio. Elll 04-A-0081 On June 12, 1984, an individual, employed at the Celiaway fiuclear Plant, was interviewed in Columbia, Missouri. Present for the interview were W. L. Forney, Callaway Section Chief; J. H. Neisler, Senior Resident Inspector at Callaway; C. H. Weil, Investigation and Compliance Specialist, and Thomas E.

Carpenter, Representing the Government Accountability Project (GAP). The interview was recorded by Patricia J. Rowe, Registered Court Reporter. The individual stated that he wished to remain anonymous. The individual was duly sworn, and the following information was summarized from the interview.

Work History The individual has worked in construction for approximately twelve years with five years experience in highway construction and seven years in hoisting work. The individual stated that he was employed in the construction department at Callaway. (Transcript Pages 5-6.)

Sprino Beneath Fuel Building The individual stated that he worked on the crew that put in the base rock beneath the Callaway Fuel Building, and he observed an excessive amount of moisture in the base rock. The individual stated that quality control inspectors checked the moisture of the rock and found the rock was too wet.

The individual observed that the rock was still wet after the fill was complete. According to the individual the rock was wet even during dry periods in the summer and this lead him to believe that a spring existed beneath the base rock. (Transcript Pages 6; 13-15; and 21.)

Water Seepage The individual noted that the bottom level of the Callaway Auxiliary Building leaked. The individual thought the source of the water may be the spring beneath the Fuel Building base rock. The leaks were stopped by using "waterplug." The individual observed that the Callaway Reactor, Fuel and Auxiliary Buildings were separated by "Rotofoam" and at the 1974' elevation the Auxiliary and Reactor Buildings were also separated by cork. He stated that the cork in a " hot room" on the 1974' elevation of Auxiliary Building was exposed and had been damaged by the water seepage. The individual was concerned that the water seeping into the cork in the " hot room" could become contaminated with radiation and then seep into the environment. The individual thought this concern could be corrected by installing a curb or wall in the " hot room" to deflect the water into the sewer. The individual made a sketch of this concern during the interview. The sketch was retained by W. L. Forney. (TranscriptPages 8-15; 21-25.)

Fuel Transfer Canal The individual stated he was involved in pouring concrete for a fuel transfer canal sump hole. The individual stated the tank that was placed in the hole was improperly mounted and the tank broke loose from the mounting studs. The individual described the mounting studs as being inadequate to hold the tank.

The individual was also concerned that the repairs to the tank caused a concrete " cold joint" which could cause the tank plating to rupture.

(Transcript Pages 15-21.)

Cooling Tower The individual also described a situation during a concrete pour for the site cooling tower's rink footers. The individual observed " mud boiling over the reinforcing rod." The individual continued to pour concrete at his foreman's direction, as the individual thought he would be disciplined for insubordination if he stopped pouring concrete. (Transcript Pages 25-26.)

I* I f;T ERVI EU f'.EF'C RA!.DUM ATS No. RIII-84-A-0082 On June 12, 1984, a quality control inspector, employed at the Callaway Nuclear Plant, was interviewed in Columbia, Missouri. Present for the interview were W. L. Forney, Callaway Section Chief; J. H. Tieisler, Senior Resident Inspector, Callaway; C. H. Weil, Investigation and Compliance Specialist, and Thomas E. Carpenter, representing the Government Accountability Project (GAP).

The interview was recorded by Patricia J. Rowe, Registered Court Reparter.

The inspector requested confidentiality and it was granted. The individual was duly sworn and the following information was summarized from the interview. The individual was concerned about radiation escaping into the environment. (Transcript Page 3.)

Work History The inspector has been employed in the Callaway quality department in excess of five years. (Transcript Pages 2-3.)

Liner Plate Welds During the Fall 1983, a laborer (NFI) told the inspector that reactor dome liner sheet welds were corroded from acid in the air. The welds were described as having no weld metal left and " places you could stick a pencil in." (Transcript Pages 3-4; 15-17.)

Concrete Voids During 1980, a concrete inspector (NFI) told the inspector of voids in the Reactor Building liner plate. The concrete inspector "took a piece of rebar and knocked on the plates... could teli the difference with the hollow ring effect in some places." The inspector thought this observation was made on Reactor Building West - elevation 2047' and possibly lower on the "same side."

(Transcript Pages 4; 17-19.)

Winter Concrete Pours During the Winter 1982-83, the inspector overheard concrete inspectors complaining of concrete being poured on top of ice. The concrete pours were for outside slabs and some attempts were made to remove the ice. The inspector noted that "sometimes they would meet their temperature requirements by having it covered... take the air temperature. And if it was over 40 they would pour concrete, but yet the ground was frozen solid, but it was documented as acceptable temperature..." The inspector did not know if nonconformance or deficiency reports were ever written on this condition.

(Transcript Pages 5; 19-22.)

Mud in Concrete forms The following Spring (19L3) the inspector observed that a concrete pour had begun on "a wall on a cooling tower building" (pessibly a pump house) without having mud cleared from the forms. The inspector noted that approximately 4" - 12" of mud stood in the forms before it was cleared out. (Transcript Pages 5-6; 23-24.)

Electrical Cables

1. Installed and approved electrical cables in the Auxiliary and Diesel Generator Building were damaged by people climbing on the cables. This

" traffic" caused damage to the cable jackets. The inspector recalled observing this condition on black colored cables in the Auxiliary Building.

2. The inspector also stated that in 1980-81 cables were sabotaged (cut).

(Transcript Pages 6-7; 24-30.)

Structural Steel Bolting

1. Structural steel was installed, bolted and inspected; however, the crafts later removed the steel and bolts to move in equipment. The steel and bolts were reinstalled, but were not reinspected. These bolts and steel which were not reinspected were covered over with concrete or spray coating. This occurred in at least the Diesel Generator Building.

(Transcript Pages 7-8;30-31.)

2. The inspector twice assisted in inspections of structural steel bolt torque and found the bolts were overtorques. Reinspections of the plates found that not only was the torque improper, but also that the wrong nuts and bolts had been used. The reinspections also found the wrong projection existed. (Transcript pages 31 32.)
3. Many times the holes were drilled oblong, instead of round, into the steel plates. This condition could not be readily determined as washers covered the holes. This "went on for a long time before they decided it was a problem" and reinspections made. (Transcript Pages 50-52.)

Welding Inspections

1. QCP 113 required the welding department to notify quality control wherever structural steel was to be welded. The common joke was that the crafts called quality control in 1975 and have not called since. Therefore, the welders "just went around and welded wherever they wanted to."

(Transcript Pages 9; 32-33.)

2. Regarding the above allegation, "a lot of these places were concreted without the welds being checked. And when they found there was some problem with it, they went to the welding inspectors with the concrete pour cards and said, 'We've got to have a welding inspection on this. '

There are some inspectors that just signed them right off, never left the office...." (Transc_ript_Pages,9-10,;.

Water Leaks

1. "They have hco a lot of problem with the water in Icwer levels of the building, and they constantly have to pump them out. And in big rains I've seen down in lower levels they had a whole bunch of cables going outside and water just pouring in there...." (Transcript Pages 10; 36.)
2. Drains were stopped up because of the weight on top of the drains. Also drains were broken because of the heavy equipment run over the top of the drains. (Transcript Page 10.)
3. " Problem in the waste water where they had this surge in water.

Everytime it rains they have this massive water flow through the well. I don't know if you call it effluent or sewage system...they've never been able to identify where it comes from... they've been looking at it for years." (Transcript Pages 36-38.)

Lost Plans

...they lost all the plans for the plumbing."' (Transcript Pages 10-11; 38.)

Inspector Certifications

1. fio inspector " training program existed at Callaway until recently."

(Transcript Page 11.)

2. Until three years ago cheating was done on inspector certification exams. Answers were given, test takers were coached, and copies of exams were available before the exam was administered. (Transcript Pages 11-12; 38-41.)
3. Daniels International conducted an investigation into the test cheating and three people who truthfully answered the questions were fired.

(Transcript Pages 12-13; 45-46.)

Deficiency Reports

" Deficiency reports are virtually extinct out there. They just always rework and don't write deficiency reports. I don't know if I should say they rework but...is common practice not to write deficiency reports, just try to get it to meet inspection requirements and not reject it at first." "They just don't want to write DRs. It makes it look bad and they think...it looks bad for their department...Plus it's too much work and they'd rather not do it. If they find something they will just have the crafts keep doing it until they think it's good enough to sign off...." (Transcript Pages 21;49-50.)

Fuel Poc1 Liner At z. bout the time the fuel pool was to be tested a hole was found in the liner. The inspector described the hole as "six inches wide, welded through the liner of fuel pool. But I'm'sure they fixed that because they had to test it to hold water..." The inspector thought this hole may have been sabotaged as "they just had it finished, just had it cleaned...I didn't really hear this sabotage. We kind a assumed it was--that somebody-- the official word going through the bosses was that a welder fell against it..." (Transcript Pages 29; 52-53.)

Radiation Exposure The inspector stated that he was intentionally exposed to radiation from a radiographers' sources. "They... keep aiming these radiograph X-ray machines at me.... It happened a couple more times...I'd go in a little place and I'd come back out and it would be on the opposite wall.... They weren't taking any pictures. I asked them. And a couple of times I'd just walk by and they flashed an X-ray machine at me, I assume just to give me radiation...." The 4

inspector stated these incidents were not related to his job as a quality control inspector, but because he "was in an environmental group...somebody...

thought they'd run me off."

The original copy of the interview transcript is being retained in the Investigation and Compliance Specialist's files.
