? INTRODUCTION
,' Comanche Peak Steam Electric Station (CPSES), Units 1 and 2, are under
,) construction in Somerville County, Texas, near the town of Glen Rose, Texas. Texas Utilities Generating Company is the Construction Permit
.; holder with Brown and Root, Inc., as the constructor and Gibbs and Hill, Inc., as the Architect / Engineer.
v REASON FOR INVESTIGATION j The Region IV Reactor Construction and Engineering Support Branch office i received a telephone call from a fonner CPSES employee who reported i several allegations indicating a potential breakdown in the CPSES Quality g Assurance program.

SUMMARY
OF FACTS A:. .
t On March 30, 1979, the Region IV Reactor Construction and Engineering li Support Branch received a telephone call from a party who identified O himself as a fonner CPSES employee. The call was taken by an on-duty j Reactor Inspector in the Projects Section who in turn provided the y infonnation to the assigned Resident Reactor Inspector at CPSES on April 2,1979. The allegations, as received on March 30, 1979, were:
4 2
1 1. During a concrete pour on the Unit 1 containment. dome in January j
1 1979, a rain occurred which washed away part of the concrete.
The affected area was repaired by the use of grout. Workers h . involved were requested to " keep it quiet." Two workers, who
,'.yj are still at the site, have knowledge of this occurrence.
9 2. The identity of a lot of "Q" and "non-Q" pipe (6" or less) being f used for Unit I has been lost due to obliteration of heat numbers i;y by sandblasting and loss of identifying tags. Workers are guessing y as to the proper identification of the pipe.
12G d 3. A steam pipe intended for the Unit 1 turbine fell off of a truck h and struck a railroad track. It was taken back to a storage area 2 and hidden. '
$ 4. Third class helpers are being qualified in less than three months j f and are being used for safety related welding on Unit 1.

e
- 1. The concrete used for the repair was not grout as originally indi-cated but was known to contain gravel. The concrete came from the W batch plant where it was mixed on the ground and carried in a bucket
,, to a tower crane at the Unit 1 Containment Building and hoisted to the dome area. The work was accomplished sometime during the middle i of the second shift, possibly around 10:00 to 10:30 p.m. (January
? 1979, no day specified).
d Y 2. The pipe in question was not prefabricated pipe but rather bulk pipe M joints. Sometimes, the pipe is sandblasted on the outside (rate of
@ occurrence not identified) which removes all of the heat marking e used for traceability.
k
'!/ i 3. The steam pipe was being moved during the second shift from the
- i ; "Dodd's Spur" storage area to the plant area when it was dropped R off the truck. A couple of the large " cherry-picker" type cranes 5 -
were dispatched to the indicent to pick up the pipe and place it C -
back on the truck. The crew with the truck decided instead to
. put the pipe back into the storage area and leave it there for M( ,
~'
another shift to pick up and perhaps be blamed for damaging the y ,
pipe. The alleger did not know if the pipe had actually suffered g any damage. He was aware the pipe in question was "non-Q" but
.o ,, expressed a concern that if the craft could get away with a cover-
$ up cn "non-Q," they probably are also doing it on the "Q" pipe and 3 v. other equimpment. .
g l , s'., 4. The alleger indicated he was concerned with what must be incompetent
'A welders working on "Q" welds, since they could not have very much y experience and still only be considered third class labor.
p ik V CONCLUSIONS
- )
d 9 Research of various records and interviews with both craft labor and 1 Brown & Root QC personnel produced the following conclusions;
- 1. The allegation relative to the concrete placement on the dome of
@f ;: Unit 1 is essentially correct and is evidence of a breakdown in d the licensee's Quality Assurance program. The incident will be 7 considered an item of noncompliance.

k' l
- 2. The allegation relating to the loss of pipe traceability markings l could not be confinned. The Resident Reactor Inspector's finding '
was that on occasion the sandblasting, with attendant loss of readily visible markings, probably does occur through human error, but that
, there are other means which will re-establish the identity of the pipe without guessing on the part of the craft labor force.
- 3. The piping in the "Dodd's Spur" storage area is for the turbine s portion of the plant and is not safety related from a nulcear
- standpoint and is therefore not within the jurisdiction of the NRC inspection program. The more generalized concern of cover-up
- of improper handling practices is not consistent with the obser-J vations of the Resident Reactor Inspector and other NRC inspectors l made during the course of routine inspections. The allegation l d cannot be verified or refuted at this time, but should subsequent j observations verify that the alleged situation is occurring, si appropriate action will be taken.
h 4. Welders are qualified in accordance with the provisions of the
- ASME Boiler and Pressure Vessel Code,Section IX, " Welding and
}
Brazing Qualifications," as required by NRC regulations and the licensee's comitments as contained in the Safety Analysis Report 4 submitted to obtain a Construction Permit. The labor classifica-tion, and therefore the pay, of the welders is not an element of
~
.}g the ASME Code welder qualification program, only the ability of s the person being tested to weld on a specified weld coupon.

- 2. Preliminary Investication - Aoril 2-3, 1979 w
. a. Allegation 1: The Resident Reactor Inspector (RRI) initiated j ,
a preliminary investigation of the allegation as soon as f c received. The RRI was aware that a number of concrete place-i ~ .' ments had been necessary to complete the dome area of Unit 1 3 g and that a substantial portion of these placements occurred ~
U in January 1979. Schedule completion data indicated that five
.i of the total of thirteen dome placements occurred in January
- 1979. Rainfall data for January was then obtained from the i licensee's meteorology unit which indicated rain had fallen on Janaury 15,1979 (with the rainfall totalizer reset to p{ zero) and again in the period between January 15 and 22,1979, when the totalizer was again zerced. The data suggested that
/, placement 101-8805-013, the final placement on the dome, was
- - the most likely candidate since 2.72 inches of rain had occurred
- about the placement date of January 18, 1979. The RRI then f; examined the QC inspection records for the placement which stated, I
- 5 " Pour stopped at 8:00 p.m.1/18/79 due to inclement weather. Pour L,i was topped out all but to a 30' radius which was cleaned up and G finished 1/19/79."
.i The RRI then interviewed the QC inspector of record for the placement and was informed that the placement had started under good weather conditions on January 18, but that the q a

weather subsequently developed into a light mist and drizzle which did not interfere with the placement. By late evening, the weather deteriorated further. and became a full rainstorm with thunder and lightning. By 7:30 p.m. or so it was decided that the placement would have to be stopped for reasons of personnel safety. The placement area was covered to keep the rain off the fresh concrete and the second shift was instructed -
to water blast and clean up the area so the placement could be t -
i resumed the following day.
- t
- b. Allegations 2, 3 & 4: No attempt was made to perform a pre-liminary investigation of these allegations since the infor-mation was too vague. -
/: 3. Licensee / Contractor Report of Allegations 2 During the course of the above preliminary investigation, personnel 1 of the licensee's management and QA organizations approached the RRI and stated that they too had received an allegation relative to
@i the dome placement. It was stated that licensee management had received a telephone call on or about March 19, 1979, on the subject dl and that licensee management had visited the alleger at his home on j March 20, 1979, to ascertain the facts of the allegation. The alleger then was invited to visit the site and discuss the allegation, which 4 the alliger is reported to have done on March 26, 1979. On the basis y of these interviews, the licensee's Product Assurance personnel under-A a took a'n investigation which concluded that the allegation had no merit.
$ e
$ , 4. Interview with Alleger by NRC Personnel .
- s' The Region IV office made several attempts to establish contact with dj i the alleger during the period following March 30, 1979, when the j allegation was received, through April 12, 1979, when the interview J, date and location were established. The RRI and another NRC inspector
,;3 met with the alleger and a friend on April 13, 1979.
4 The alleger provided the following information about himself: ,
$ a. He had been employed by Brown & Root at CPSES for 2-1/2 to 3 H years and had quit in mid-March because he was dissatisfied with how the night shift equipment operators were being dispatched and supervised.
n 9 b. He had been an equipment operator, primarily on cherry-pickers, y and also a foreman for equipment operators at an earlier time.

9 c. . He stated that he had made the allegations to licensee management
! and Brown & Root management earlier but had not been at all sat-
, isfied with the answers he had received to his allegations.
The alleger provided the following additional information relative to .
each of the allegations: .
1 -
Allegation 1: The incident occurred well after the time that the placement had been stopped. He could not be sure of the
{ time but thought it was probably 10:00 to 10:30 p.m. when some 3 equipment was dispatched to the concrete batch plant to bring
. down a bucket of concrete to Unit 1 and thought it strange. The y concrete was taken to the dome by a tower crane. He was sure that.the concrete ,was not batched by the batch plant and certainly was not delivered by the usual concrete mix truck.
T Allegation 2: The alleger made it clear that he was not referring
- to completed pipe spools but rather to bulk pipe. The cherry-y picker operators routinely move the pipe from one location to g another on the site and that the pipe involved was bulk pipe or
, joints. He stated that the pipe was sometimes sandblasted in such 4 a way as to obliterate the heat number markings or tags and that he was pretty sure that there was a lot of unidentified pipe in i the safety systems in Unit 1. This sandblasting sometimes happened
.i to various steel fonns used to make supports.
v Allegation 3: The alleger described being dispatched with his g
( j. equipment out to "Dodd's Spur" to pick up a length of pipe that
. had fallen off a truck after being loaded. . The pip'e had fallen d , on the spur railroad track. The RRI was not familiar with the f '
- term "Dodd's Spur." The alleger stated it was the area were the in turbine components are stored. When he (the alleger) arrived at 3 the site of the incident, he was told not to reload the pipe on j the truck but to take it back into the storage area and put it down. The pipe crew indicated to him that they hoped that a day
]i shift crew would come for the pipe and would probably be blamed L for any damage that might have occurred to pipe when it fell.
y He stated that he did not know if the pipe had been damaged. He S stated that he knew it was "non-Q" pipe but thought the NRC should Q be aware that such things were going on at the site.
I.a it 5. Final Investigation - April 16-23, 1979 n.P
- a. Allegation 1. The RRI obtained the craft labor time sheets for
&q both shifts for January 18 and 19,1979. Review of the time 1 sheets for the day shift on January 18 indicated that a portion V of that shift worked on placement 101-8805-013. The records indicated that the day shift was terminated at approximately b

<3 8:30 p.m. relative to the placement as were the personnel at the concrete batch plant. The batch plant has no second shift operators.
. _ . . . . _ The RRI found that a large number of. people, well in excess of fifty,
, had then worked on the placement during a substantial portion of the 7 second shift. One crew of twelve people was shown by the time sheets i to have been placing concrete, a notation not consistent with the i~ fact that the batch plant was closed during the shift. The RRI then utilized the time sheets to develope a list of persons to be inter-
.- viewed in connection with the incident with special concentration it on the persons listed on the time sheet indicating " placing concrete 5 101-8805-013." The B&R personnel office records indicated that
[ -
eight of the ten names included in this specific crew had been terminated at various times since January 18; the records did not 2
.)
y suggest that any action was being taken to get rid of possible 1 confirmatory personnel.
Jg Late on April 17, 1979, two of the senior B&R construction manage-1 ment personnel very. informally asked the RRI how the investigation 4 of the allegations was coming along. The RRI responded that the i on-site phase appeared to be complete and that NRC personnel would g .
undertake the effort to locate and interview selected personnel t imediately since it appeared that the allegation might be well 7 founded. They asked the RRI if they could check with their people ,
? down to the General Foreman level as .to the incident the night of '
'4 -
January _18. The RRI indicated that such an inquiry on their part ij would probably not interfere with any future investigative action 4 by the NRC.
m .
f .
q On April 18, 1979, the licensee's product Assurance Supervisor informed the RRI that he had information which indicated that the 7 .:> incident had occurred and that the craft General Foreman was the
' 'ij person responsible.
-s.
j On April 23, 1979, the RRI, accompanied by another NRC Inspector, e interviewed the General Foreman and his imediate supervisor, the i: night shift B&R Building Department Superintendent. These men I related that on the night of January 18 the weather seemed to worsen j '
and got to the point where the rain was so heavy that the people d could hardly see. The freshly placed concrete developed into a problem when the plastic cover could not take the rainfall water 1 load. Some of concrete began to sag back down the dome slope and
.b i$ one small area actually washed out and fell to the ground below.
t These men related that they and their entire crew of up to about
,$ one hundred-fifty worked on into the night trying to save a very
@ bad situation. The sagged concrete was worked back into position y and the crew protected it in any way they could to allow it to
- $ take a set.

9 d
d The General Foreman went to the batch plant, got it open and operated the plant himself to make enough material to patch the washed out area. He stated that he found the design mix data
.. used for the concrete on the. dome and calculated the necessary 4
weight of ingredients to prepare a half a cubic yard of concrete.
The required data was put into the control system for the back-up dry batch plant, dropped into a skiff, and carried over to the quarter yard concrete mixer at the site test laboratory. It was
. mixed in two batches and placed into a skiff and carried to the -
i dome where most of the half yard was used as a patch in the j
washed out area.
i Both the General Foreman and his Superintendent were aware that m there were no Quality Control personnel around to observe any of y these actions since they had all gone home when the weather got e . really bad. Both men related to the RRI a picture of almost panic 4 proportions in which the presence or absence of Quality Control simply did not matter; they were going to save a concrete place-
%} ment from what they considered a disasterous situation, regardless.
They indicated that while the night shift Assistant Construction j; Project Manager was generally aware of the situation on the dome
.) that night, he probably was unaware of the fact that Quality Control personnel were not there or of the batching of the concrete l' . under the conditions indicated. -
)j In response to a question from the General Foreman as to "what happens now" the RRI stated that the NRC had no choice but to
, issue a Notice of Violation to the licensee since it had become 2 .. very clear that the licensee's Quality Assurance program had 4.{ c broken down for the entire evening of January 18, 1979, and that
< ~
L a substantial amount of concrete on the dome was of an unknown
- . quality.
c b. Allegation 2. The RRI visited the paint shop sandblasting area J during the course of the final investigation to ascertain if j this allegation could reasonably happen. The RRI interviewed a T foreman of painters who is also in charge of the sandblasting
? activity and was told that three main categories of piping
'i. material routinely are sandblasted. These are:
3 C (1) Completed carbon steel spool pieces which are blasted on the outside prior to painting. The identity of these
- pieces is on an attached stainless steel band on which F the identifying is encoded by stamping. Should the band w come off, the spool piece identity can be re-established
+: by the pipe fabrication shop since each spool is unique and is fully described by isometric drawings.

(2) Carbon steel cut lengths, but otherwise in an unfabricated l condition, are sent to sandblasting to have the inside cleaned prior to further fabrication. The outside, which usually carries the heat marking in paint-is supposed to be untouched. .
1 1
'.i (3) Bulk carbon steel pipe materials used for making equipment stands and supports is blasted and painted prior to fabrica-tion. The material is used for such items as instrument supports.
e E The RRI found a number of examples of each of the above categories as well as steel shapes in the sandblast area. During the tour of i t the area, the RRI did not find any material that could rot be !
? identified except that in category three. The RRI interviewed one E of the sandblasting personnel and came to the conclusion that the 2 person might.make an occasional mistake on category 2 material j since he seemed confused when asked what he was going to do with i.; a number of pieces ready for him to work on. It appeared that he
? might well blast the outside of a pipe when he should blast the n inside.
) .
9 Subsequent discussions with the paint shop foreman and with a T Brown and Root Quality Control inspector in the pipe fabrication shop revealed that all cut, but unfabricated material, is trans-c ferred to the paint shop by memo which details the size, schedule :
o and length of the cut section and the pipe spool isometric drawing
- involved. Should the outside of the pipe be inadvertently blasted,
? the piece can be reidentified relatively easy by measuring its size, f -
schedule and length. The isometric drawing used to make the cut t .3 length is annotated with the pipe heat number prior to the cutting
}
~
./. operation and verified by QC. It appeared most unlikely to the i RRI that two otherwise identical pieces but with different heat
?!l numbers would be inadvertently blasted within the same time period.
i The RRI concluded that the allegers remark that " workers are
,i guessing on the identity of pipe" might be true, but that there
'[ was an adequate cross-check system built into the quality assurance M program to preclude untraceable pipe from being installed in the j safety related systems.
All of the steel shapes used in safety related supports for pipe and cable tray that have been examined by the RRI and other NRC y inspectors have been sufficiently marked to establish their origin.
W These materials are also subject to a system of quality control verifications at various stages of fabrication sufficient to make
% it very unlikely that any improperly identified or unidentified i5 material is used and installed.

- c. Allegation 3: Based on the interview with the alleger, no further ,
action was taken to investigate the specifics of the allegation !
since the. pipe in questian was clearly not-safety related and therefore not within the jurisdiction of the NRC inspection pro-gram. The more general concern that the pipe handling incident was a possible indicator of the general attitude of the craft s , personnel, particularly the riggers and pipefitters, appeared to
, be unfounded. The RRI has observed durin j the past nine months (since August 1978) g many that plant tours the material hand-over
=r ling activities of the craft personnel have been accomplished i under well controlled conditions in so far as they relate to
" safety related equipment and materials. An allegation of possible 3 cover-up of improper actions by the craft personnel in behalf of
- other craft personnel is almost impossible to either confirm or Jy; completely refute. -
- d. Allegation 4: No further investigation was made into the charge P[
f i that third class welders are being used to perform safety related m piping system welds on the basis that the welders are all qualified j
under a program prescribed by the ASME Boiler and Pressure Vessel J l Code Section IX, " Welding and Brazing Qualification." The applica-6; / tion of the Section IX program has been reviewed a number of times
- 9; by the RRI and other NRC inspectors since it was implemented at 3 '
CPSES. The implementation has been found to be consistent with
- j ~
the requirements. These requirements, however, do not address b themselves to the experience or inexperience of the person seeking M qualification as a welder, but rather to whether he can accomplish
,f y a weld in one or more of the Code prescribed positions that will Js i pass the test criteria imposed by the Code: The terminology " third
.j i class," as it applies to the labor force, relates primarily to the y .
j ( pay category in which a person is hired and previous experience 4 -
\. is a factor in this determination. -

Even though no items of noncompliance with NRC requirements were identified l
[ during this investigation, we did find that the allegations were essentially ,-
. . . true. We also noted during this investigation that a thread of continuity j existed between this investigation and others recently conducted relative to ,q j alleged problems with site canagement and quality control in certain areas of construction. Although we feel that the major organizational changes you
.made in January 1978 have strengthened the QA/QC program at Comanche Peak, we .
cannot ignore the fact that we are continaing to receive allegations concerning .
^ construction practices. Taken individdally these allegations, some of which l have been substantiated, 'do not appear to have any significant adverse i= pact -
on the conformance of your plant to NRC cr-"4 tments. Ecwever, as we discussed in our meeting with you and M in our office on June 22, 1979, when :
- these allegations are taken collectively, there appears to be a morale problem l which is evidenced by several of the allegers and may be attributable, in' !
part, to co:.munication proble=s,between the workers and supervision. In our Jdne 22 neeting, you indicated that you would look into these apparent . !

- 2; INTRODUCTION Comanche Peak Steam Electric Station (CPSES), Units 1 and 2 are under construction in Somervell County, Texas, near the town of Glen Rose, Texas.
Texas Utilities Generating Company is the Construction Permit holder with Brown and Root, Inc. as the constructor and Gibbs and Hill, Inc. as the Architect / Engineer.
A REASON FOR THE INVESTIGATION The Region IV Reactor Construction and Engineering Support Branch received a telephone call from a former CPSES employee who reported several allegations indicating a potential breakdown in the CPSES Quality Assurance program and
- a possible threat to the health and safety of the public. The substance of
- , the allegations also appeared in an edition of the Fort Worth Star-Telegram
- published on May 30, 1979.

SUMMARY
OF FACTS The Region IV Reactor Construction and Engideering Support Branch received a a telephone call on May 25, 1979, from a party who identified himself as a former CPSES employee who had worked as a Boilermaker welder. The call was
- taken jointly by the Branch Chief and the Section Chiefs of the Projects
., Section and the Engineering Support Section who in turn provided the infor-mation to the assigned Resident Reactor Inspector at CPSES on May 29, 1979.
s s(.The allegations were reviewed with the alleger in an interview which took
. f place on May 30, 1979, at his home. Each of the following allegations relate to welding of stainless steel liners in the Unit 1 Reactor Containment Building or in the common Fuel Handling Building:
- 1. Allegation No. 1 1I u
? Welding and weld repairs on the liners were difficult because water from e concreting activities had run down the leak chase channels and out past
/ the backing strip into the weld area. Welds finally completed were very
% poor; some welds had been slugged with weld rod and others were so thin that if buffed a second time with 120 grit, they would not have passed PT (Penetrant Test).
- 2. Allegation No. 2
~
There are problems with the gate guide (refers to a gate in the Reactor Containment separating the refueling pool from a small storage pool and the transfer canal).
1/The statements above are the allegations as received. Clarifications obtained from the alleger during the interview of May 30, 1979, are indicated by parenthesis.

[ a. The gate guide between the large and small pool was welded in the shop. When the gate guide was installed in the pit, the end bevel was cut off so it could be fit-up. When the guide was installed,
. it was not rebeveled and where a fillet weld of 3/8" was required, only 3/16" fillet weld was made.
- b.
- The gate guide had to be welded to both sides of the liner. When welding the back side, the welder had to crawl down between the rebar to get to the weld. The position was so crowded that the welder 1 could not make a good weld. Also, the welder couldn't see what he was welding very well.
[ c. Six inches of the chase channels were left off the gate guide and added after the gate guide was installed. The rebar was so thick
$ in the areas where welding was performed that "you could hardly get your finger through, much less the welding torch." Consequently, d, the welds were not made properly.
~
3 Of 3. Allegation No. 3 2 'h 3 '
Welders have no experience. They spend as much as 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> trying to make a test weld. They finally learn how to make a weld that will pass t I the qualifying test and then when they get into the field they dca't know L what they're doing.
? . :
., 4. Allegation No. 4 5
y There is " lots" of QC coverup. QC is " buying-off" on welds over the phone.
et e, - One QC inspector bought off a seam before he ever saw the seam and it was a not a good weld because water was coming through while the weld was being s
. made. (The buy-off involvel was joint preparation and cleanliness prepar-t , atory to welding).
b 5. Allegation No. 5 Brown and Root is not following procedures in welding the liner plate.
x (The procedures referred to are welding procedures and specifically refer
. ; to use of a down-hand welding technique being used versus the procedurally e required up-hand technique).
.c f 6. Allegation No. 6
[ Some of the top seams 18" above water level on the fuel pool had backing T strips tack welded to the liner plate. There are places where the plate did not cover the backing strip. He would not guarantee the weld. The weld was probably 60% rust, air, concrete, etc.

9 CONCLUSIONS Review of the CPSES Final Safety Analysis Report, Project Specifications and
- , Engineering Drawings, as they pertain to the liner fabrication and installation,
_ have led to the following conclusions relative to each allegation stated in the a Summary of Facts above. To better understand these conclusions, the following
- considerations are necessary
The liner systems are not installed to prevent or mitigate the conse-C quences of any of the postulated design basis accidents, but rather are installed to prevent an excessive burden on the liquid waste
., collection and disposal system and to allow the wall and floor area
- to be more easily decontaminated a'fter pool usage. The liners as
- a functioning element are, therefore, not considered safety related
? and are not normally included in the NRC inspection program.
d
? The liners, as passive elements and parts of the building structure, Q are usually classified into seismic Category I since if one or more 9
of the liner plates were to become detached from the wall, serious damage could be done to stored fuel assemblies. The plates are,
- therefore, secured to the concrete supporting structure with a system N
of weld studs attached to the back of the plate and embedded into the
~,
concrete. The weld stud system is not a factor in these allegations.
r i b 1. Allegation No. 1 i
.c _.. The RRI, based on the interview with the alleger and with other welders,
{ $ has become- reasonably sure that there were difficulties encountered by 0 :. the welders with water, moisture and in some instances with concrete on
'.5 ir the weld surfaces and that in some instances, the welds may not be com-lA .; pletely sound internally. These welds, however, serve no strength purpose ig -
and need only to be smooth and leak free, factors which are established 1 by visual inspection, dye penetrant examinations, and by vacuum box tests f of the joint after it is complete. The allegation, while probably true, I
has no safety consequence.
'3 y 2. Allegations No. 2.a, b, & c -
- L These collective allegations, while probably true in a substantial sense, N also have no safety consequence. The weld joints ir questica only need to be smooth and leak free in the case of a. and b. and leak free in the case of c. The welds do not serve to lend strength to the structure.
l' 3. Allegation No. 3 h ,n The project specifications for all welding, including the pool liners,
( $ require that welders be qualified under the requirements of the American l Society of Mechancial Engineers, Boiler and Pressure Vessel Code,Section IX or a comparable requirement such as those of the American Welding

.* Society.Section IX of the ASME requires that a welder must perform a weld process involved and the as-welded coupon must pass specified tests when complete. No time limits are specified or implied as a requirement in Section IX for making the qualification test coupon weld.
The RRI has verified previously that the site welder qualification pro-gram is in full compliance with Section IX.
- 4. AIlegation No. 4
- The RRI examined the circumstances surrounding the specific portion of
., the allegation and discussed the matter with the QC inspector directly involved. It appears that this man, on occasion, was depending on the inspections performed by a fellow inspector and so recorded on the
^
appropriate weld data card. The joint was covered over with tape after
,( it had been inspected for cleanliness and fit-up and the inspector re-i leased it over the phone based on the record card entries. Water in the A leak chase channels appears to have been a constant problem. The QC
? inspector may have made a judgement error in not re-examining the joint, q but not withstanding, the joint had been inspected and found satisfactory
.h at that time. The RRI did not investigate the alleged " lots" of QC coverup y because of the lack of specifics.
x ,
a 5. Allegation No. 5 9
f 4 As noted in the Summary of Facts, the general allegation of failing to j follow procedures was subsequently refined in the interview with the 4 alleger to relate specifically to an occasion where the alleger was d: it directed by his supervision to weld down-hand rather than up-hand as i .% required by the welding procedures. ASME Section IX indicates that such c.1 p a change is in the category of a non-essential variable and, therefore, y '4 is not a prohibited change in the procedure, if recorded. It appears J , i that the change was not recorded. Interviews with other welders on the y -
same activity failed to reveal any similar experiences and supervision has denied directing the alleger to perform out-of procedure. The RRI, there-
- fore, has no mechanism by which to confirm the allegation. Again, assuming
,. that the alleger did weld down-hand instead of up-band for whatever reason, j$ the consequences of such an action are essentially meaningless as related 6 to a weld, since such a change has no effect on the finished weld of the 1 type involved.
t" 6. Allegation No. 6
,1 The particular welds in question are even less consequential than the other
$ seam welds in a functional sense. These welds, which are above the water
{h line in the pools, do not need to be leak free, just smooth for the purposes e of easy decontamination. The allegation, while perhaps true, has no conse-
. quence.

.4 DETAILS
- 1. Persons Contacted Alleger 4
The alleger, hereafter identified as Individual "A," is a former employee of Brown and Root, Inc. (the site general contractor). The person iden-cified himself as a former welder assigned to the millwright / boilermaker unit of the construction force.

- 2. Background of Allegations
, j- Individual "A" contacted the Region IV office at approximately 9:25 a.m.
- .i on Friday, May 25, 1979, to express concerns about the welding activities L
i which had taken place on the spent fuel pools, cask loading pool and the
' .f transfer canal in the common Fuel Handling Building for both Units as well as that work accomplished in the Unit i refueling pool and temporary storage y
pool installed in the Reactor Containment Building.
- The RRI was notified of these allegations on Tuesday, May 29, 1979, (May 28
? a holiday) and initiated an i==ediate investigation. The first point of contact was the licensee's site Quality Assurance supervisor who infor=ed j the RRI that he was aware of the allegations, since his company had been
$ apprised of them by a newspaper reporter employed by the Fort Worth Star-Telegram.
> The site supervisor also informed the RRI that another welder, Individual "B," had expressed similar concerns to the Project Construction Manager
% on May 23, 1979, and that concerns had been forwarded to site Quality
?!
4 Assurance for investigation. The RR1 was provided an informal memorandum giving the results of the investigation dated May 23, 1979.

1 Individual "A" also contacted the Project Construction Manager on May 24, 1979, and expressed essentially the same concerns as those expressed by Individual "B" and which in turn he expressed to the Region IV office on
- May 25,1979. It appears that Individual "A" and his supervision, up through the Project Construction Manager, had reached a substantial point
- ' of disagreement and Individual "A" voluntarily terminated his employment at the site as of May 24, 1979. The voluntary termination is a matter of record in Individual "A's" employment file.
- 3. Investigation T The RRI initiated the site phase of the investigation by extensively
- reviewing the CPSES Final Safety Analysis Report in order to ascertain 4 the safety classification of the various pools and pool liners involved j in the allegation and to review the functional descriptions. Reference y to Section 3.2, " Classification of Structures, Components and Systems,"
t in the FSAR does not indicate the liners as being safety related although y the buildings in which they exist are shown to be in seismic Category I.
3 Paragraph 3.8.3.7.1 provided a commitment to test the liner seams via a vacuum box for leak tightness and briefly described a leak chase system
?j behind the liner seams. Paragraph 3.8.4.1.3 provided a brief additional j description of the function of the liners. Figures 9.3-9 and 11.2-4 5 revealed that the extensive leak chase system has lead-out piping which s leads to a building sump and hence into the liquid radioactive waste
? collect; ion and disposal system.
e a
? The RRI then obtained Project Specification 2323-SE-18, Revision 3,
, " Stainless Steel Liners," to ascertain what requirements the design engineer
& .: had established for the liners. The RRI noted the following significant j items from the specification: -
3 j e, a. The design engineer invoked the general quality assurance requirements j -
of 10 CFR 50, Appendix B on the fabrication and installation work.
g 3 b. The design engineer provided three full pages of detail requirements
- relative to the system of studs to be welded to the reverse or concrete backed side of the liners.
L.}
W
@ c. The design engineer made reference to the inter plate seam welds only by requiring that the welding procedures and welders be qualified to f[
l ASME,Section IX. Criteria for finished welds require that, " Surfaces of all welds shall be smooth and free of any irregularities such as l%
%j serrations, ridges, crevices, or pinholes which may make it subsequently
$ difficult to achieve an effective washdown of the liner surface." Under 4 testing the design engineer provided the following, "All seam welds j shall also be tested by vacuum box for leak tightness for their entire i4
,v leath." No other quality requirements were imposed on the seam welds.

l
- d. The RRI then obtained the design engineer's drawings S-0831 through S-0834, SI-0560, MI-0581, all of which provide details of liner l fabrication and installation. In addition, the RRI obtained vendor design detail drawings for the gate guide installed in the Containment i Building between the refueling pool and the temporary storage pool.
These drawings, taken collectively, showed that the design engineer had designed a system wherein the liner plates and the gate guide
, would be supported by and anchored to the surrounding concrete walls by a very extensive system of "T" headed studs welded to the concrete
, sides of the plates and gate guide frame. The seam welds are entirely from plate-to plate and provide no attachment into the basic building
"., structure.
The RRI concluded on the basis of the above information that the liner
,. system had been designed such that resistance to seismic effect was vested L in the "T" headed stud installation and that the seam welds were necessary 7 . only to provide a very low leakage path for the pool water and that what
.? . leakage might occur would be drained to an appropriately designed method y of disposal.
U y The RRI interviewed Individual "A" on May 30, 1979, in conjunction with the 2
Region IV Reactor Construction and Engineering Branch, Projects Section Chief, in order to gain additional information relative to each of the
.g allegations received over the telephone on May 25, 1979. The additional .
. information and clarifiedtions were as noted in the Summary of Facts
,y included in this report.' In addition, Individual "A" acknowledged that he i- had only very recently become aware that the stud system existed for
'S : holding the plates in place and was, in fact, unaware that the leak A j chase channels were piped to a collection point for controlled collection j j and disposal of any leakage ,which might occur.
g
.; i
^g .i The RRI interviewed Individual "B" in the presence of the licensee's site 3 QA supervisor, also on May 30, 1979. (This arrangment was allowed since i Individual "B" only came to the attention of the RRI through the assistance of the licensee's representative.) The allegations of Individual "A" were (i-' reviewed in detail with Individual "B" who essentially confirmed Allegations 1, 3 and 6, but indicated he had not worked in the Allegation 2 area and e further indicated that he had no complaints about lack of effective QC nor lj had he been instructed not to follow welding procedures.
h
? The RRI interviewed Individual "C" on May 31, 1979, with the.same results py as those obtained in the interview with Individual "B." Individual "C" p indicated that he perhaps was one of the persons referred to by Individual "A" in Allegation 3. He also indicated that be had very limited welding
$e experience before coming to work at CPSES and none in "Heliare" weld process.
- $ He was given some forty hours of very informal training and then used fifty-two 3 hours to make his weld test coupon, a duration that he now considers to be excessive. He now thinks that he is a good welder.

. The RRI interviewed Individual "D" on May 30, 1979, and again June 1, 1979, to develop any facts relative to the specific allegation of " buying-off"
- joints over the phone. Individual "D" categorically denied that he, or to
'} his knowledge any other QC inspector assigned to this work area, had ever
" bought-off" a designated inspection point without making the required 9 inspection. On June 1, 1979, Individual "D" indicated that there had been j very few occasions when he had given consent to the welders to weld up a a se'am that, by the inspection reports, had been previously inspected for' a fit-up and cleanliness. He also indicated that he and others had repeatedly
? stopped work on welding of seams where it came to their at' ention that water
{ or moisture was interfering with good welding.
$ The RRI interviewed the Boilermaker Superintendent on June 4, 1979, relative f to his knowledge and/or participation in any of the allegations. He cate-2 gorica11y denied ever directing welders to make welds where water or moisture j was present, but acknowledged that it was a constant problem. He indicated j that he finally received engineering permission to drill holes through the y liner at the ends of the leak chase channels so that air could be blown 1 through to dry out the channels and that this action helped a great deal.
1 He indicated that he had continuely attempted to impress the welders with 4 the importance of making good seam welds.
Sy 2 4. RRI's Assessment of the Liners
,p
. .t
} The RRI observed some of the welding work 6n the refueling pool in the Unit
- . No. 1 containment during the latter part of 1978 and the early part of 1979
$ . incidental to making inspection of other activities in the same work area.
2 , ( The welding appeared to be normal and the dye penetrant examinations appeared M 3 to be properly accomplished. The finished surfaces examined have been uni-g4 ) formily smooth and appear sound. The RRI also examined some unfinished areas 3 ( in the Unit 2 spent fuel pool and can appreciate the difficulties that may be g { encountered in removing some of the concrete laitance from the vertical weld joint areas.

0, 1 INTRODUCTION Comanche Peak Steam Electric ~ Station (CPSES), Units I and 2 are under construction in Somervell County, Texas, near the town of Glen Rose, Texas. Texas Utilities Generating Company is the Construction Permit holder with Brown and Root, Inc.
as the Constructor and Gibbs and Hill, Inc. as the Architect / Engineer. ,
REASON FOR THE INVESTIGATION 4
The Region IV Reactor Construction and Engineering Support Branch Chief received a letter addressed to the Headquarters if the Nuclear Regulatory Commission in Washington, D. C., which contained alleg:tions that indicated a possible i breakdown in the CPSES Quality Assurance Program.
SUMMARY
OF FACTS A .
j .
The Region IV Reactor Construction and Engineering Support Branch Chief received j c. a letter dated August 1, 1979. The letter, which was addressed to the Headquarters j - of the Nuclear Regulatory Commission, was received by Region IV on or about q
August 14, 1979, and forwarded to the CPSES Resident Rea'ctor Inspector (RRI)
M for follow-up on August 15, 1979. The letter contained two allegations
. apparently received by the alleger from two other persons. The RRI and another b .
Region. IV Reactor Inspector interviewed the alleger on August 15, 1979. The 9 #[. following information was extracted from the letter. Additional information, f , included within parenthesis, was obtained from the alleger during the
- !j .-
interview.
(r;
$ ( Allegation 1: The letter attributes this allegation to a former CPSES 0
} ,
employee, who was the " chief welder" at one time, and stated that he knew of " numerous employees, men and women who, if they proved they could weld B i o a straight line, were allowed to weld and most didn't know the difference
( between a 5 ton weld or 25 ton weld." '(The alleger concurred that the RRI's 1 interpretation of his letter was accurate and provided a last name for
$ the welder and a means of contacting him. The alleger was of the opinion H (
that the NRC did not need to be concerned with this allegation since 3 \ it had been addressed in one of our previous investigation reports.)
& Allegation 2: The letter attributes this allegation to a CPSES employee b now retired for health reasons and relates to an event that occurred during 1 a Christmas party held December 1978. It was alleged in the letter that an individual, who worked for Brown and Root during the month of December 1 1978, was on the job and attended a Christmas party being given for the
!! employees. This occurred December 2, 3 or 4th. The letter stated that
'I the individual observed " considerable drinking and all employees were i quite drunk, except for the individual whose job was to drive a vehicle H 3

.a .
d to take the employees home when they became too drunk to stand." During the party, a load of " cement" came in to be poured. The foreman, without supervision, made the workers pour the " cement" into the forms after he
- had the men clean up the area and put the trash, garbage, bottles and cans in the forms. The letter implies that. the concrete placement took place on or in one of the two Reactor Buildings at CPSES. (The alleger m provided the IE inspectors with specific directions on how to locate the individual and affirmed that the alleged incident took place in a Reactor Building.) -
o 1, CONCLUSIONS sl l The following conclusions are based on known conditions at CPSES, review of
{
E.;
indicated records and an interview with the individual involved in Allegation 2 which took place on August 16, 1979, in'the individual's home.
2 y Al' legation 1: This allegation was determined to be without merit. There j is not now, nor can it be established that there ever has been a " chief
- welder" at CPSES. The terminology "5 ton or 25 ton weld" is unfamiliar among j ,
IE personnel with individual and collective years of welding engineering j or inspection experience. IE inspectors have determined that all welders l'J ".'
at CPSES are qualified to either the requirements of the American Welding
/ Society or the American Society of Mechanical Engineers prior to performing
$ production welding. The implementation of the welder qualification program 1,) at.CPSES has been the subject of several routine inspections by IE inspectors 3 .g since welding began at CPSES. No major deficiencies have been identified
.S .: 1 in the program.by these inspections.
u 3 ,
y /. Allegation 2: This allegation could not be fully substantiated nor ' refuted,
,j j.; but for the reasons delineated below, it apper.rs that there is a small likelihood that the allegation has substance:
~
r
'j w
- a. The individual from whom the alleger states he received the
- i information denied having ever participated in a party on
'} CPSES property or that he ever had knowledge of such a party.
- h He also denied having given any such information to the alleger.
S i ?,) b. The only Reactor Containment Building concrete placement that
-y took place in the specified time period was on Unit I and occurred Y on December 3, 1978. Examination of the Brown & Root t.iue
- ,3 keeping records for that day established that the individual was not on payroll status that day and it is very unlikely that
?h he would have been allowed on the station as a visitor.
- 9
'- c. The RRI was able to establish telephone contact with one of the former Brown & Root employees shown by the time sheets s to have in some capacity been involved in the concrete placement in question. This person stated in the telephone conversation

rather in an unspecified cupport capacity. lie stated that he was unaware of any parties on the site during that time
- frame- and doubted- that such a party-had taken place.
- d. Considering Brown and Root's policy in regard to worker discipline, it is not likely that Brown & Root would sponsor S such a party for any or all of the more than two hundred workers on the station that day nor would such a party even be condoned if sponsored by the workers themselves.

- 2. Background Information
?
0 The alleger sent a letter dated August 1,1979, to the Nuclear Regulatory Commission, Washington, D.C. The letter was received by the Chief, Reactor p Construction and Engineering Support Branch, Region IV in Arlington,
? l.. Texas, on or about August 14, 1979, and was immediately forwarded to
? ;
the Comanche Peak Station (CPSES) Resident Reactor Inspector (RRI) for
? 1[;
. investigation. The RRI determined that the letter contained two 3 :.
different allegations made by two individuals, neither of whom was the
- j . ; alleger. In summary, the allegations were as follows
'i a. Individual A is indicated in the alleger's letter as having been a " chief welder" at CPSES. Individual A is stated to have indicated 1 to the alleger that "anyone, man or woman, who could weld a y straight line, was allowed to weld, but most would not know
..j ( the difference between a 5 ton weld and a 25 ton weld." -
k b. Individual B is stated in the letter to have been a former e Brown and Root employee who is on a pension from Brown and Root for medical reasons. Individual B is stated as having attended y a Christmas party on the site during December 1978 given by
.h Brown and Root. Individual B's job that day was to drive 3 home the workers who became too drunk to drive. During the
/< party, a supervisor required the workers to clean up all the
- " trash, garbage, bottles and cans" and place them in the form J work of an ongoing " cement" pour. The alleger implied, in the
? text of the letter, that the incident took place during a
- Reactor Building concrete placement and specifically states that it occurred on December 2, 3, or 4, 1978.

y 3 3. Interview with the Alleger E
{ The RRI and another Region IV Reactor Inspector visited the alleger during
- the afternoon of August 15, 1979, in order to obtain the identity of J. Individual A, which was not given in the letter, and to obtain the j address of Individual B, who was identified in the letter. The alleger 1 provided a last name for Individual A and the name and telephone number
? of another person through whom Individual A could be contacted. The
{ alleger also stated to the IE inspectors that it would not be necessary 1 to further check out the allegation relative to welding since he, the 4 alleger, had reviewed a recent NRC investigation report that addressed 1 the issue to his satisfaction. During the discussion, the alleger affirmed y the implication that the " concrete party" allegation did involve one IT of the two Reactor Containment Buildings at CPSES but indicated he did j not know which. The alleger gave the IE inspectors explicit instructions p on how to locate Individual B in a nearby town.
h
.a
- 4. Interview with Individual B m
j The IE inspector immediately drove to the nearby town following the alleger's 4 instructions. The residence was at the time unoccupied although apparently t lived in. The residence next door, occupied by Individual B's father, 3 according to the alleger, was found locked and/or boarded up and was
$ apprently abandoned. The IE inspectors visited the local police depart-g ment where it was learned that Individual B generally was listed by his y second name rather than his first. No address was available, but a d telephone number was obtained. The number was not answered during'the j g period of the visit, but the RRI did succeed in contacting the person g .f
. during the evening of August 15 and arranged for an interview on s -
A.ugust 16.
$- c;, The two IE inspectors interviewed Individual B at his home (not at the f'Ni location given by the alleger) on the afternoon of August 16, 1979. Also attending the interview was Individual B's wife. Individual B stated
$ that he was aware of the allegation attributed to him since a reporter h for a major national newspaper had visited him on or about Sunday, August 12.
/ Individual B indicated that the alleger had sent a copy of the letter to g the newspaper. Individual B also stated to the IE inspectors that the 4 allegations attributed to him were completely false in every aspect. He h stated that he was not sure how the alleger, who was well known to him, got g the story of the party, but that it wasn't from him. He also stated that 7 while he had recently had major surgery, he was not being given a pension by Brown and Root nor was he receiving any other money from Brown and Root.
W y
- 5. Investigation Allegation 1: No investigation was performed of the allegations purportedly 2)
U. made by Individual A for the following reasons:
~..,.
y '
- a. The alleger had stated to the IE inspectors that no further
, investigation was necessary.

- b. CPSES does not have nor has ever had a person identifed as a
" chief welder."
s' c. The allegation deals with the idea that the welders employed by Brown and Root are not qualified since they, the welders, would not know the difference between a 5 ton weld and a 25 ton weld. The RRI contacted several experienced welding engineers and inspectors in the NRC about the terminology, none of whom were familiar with it. Reference to the six volumes of the " Welding Handbook" published by the American
{ Welding Society failed to reveal any reference to the strength or quality of welds in terms of " tons" value.
- d. It has been well established that welders employed at CPSES
- are now, and were during the period of employment of
- Individual A at CPSES, tested and qualified in accordance with the standards of either the American Welding Society or the D
American Society of Mechanical Engineers, as appropriate, for W the work involved.
i
( Allegation 2: During a review of records at CPSES, the RRI established the following facts:
4.: -
3 a. No concrete placements were made on Saturday, December 2, 4 1978. i
~:1
- b. A single placement of concrete was made on Sunday, i s December 3,1978. This placement was the second lif t of ly .i concrete on the dome of the Unit 1 Reactor Containment
{ Building and involved a placement of slightly over three
- hundred cubic yards of concrete at an elevation approximately j J(- two hundred feet above ground elevation.
2..
- c. Two relatively small placements of concrete were placed on Monday, December 4, 1978. These placements, totaling approximately sixteen cubic yards, were in the Safeguards Building of Unit 1 and in the common facility Auxiliary Building.
3 "
- d. Working on the basis of the affirmed implication that the party took place during a Reactor Building placement, the RRI checked the labor crew time sheets, including those of the
+ crew to which Individual B was known to have been assigned.
!/p Individual B's name does not appear on any of the records for Sunday, December 3,1978, and therefore, it appears very unlikely that he could have been on the site to drive the
" drunks" home. Had such a party taken place, Individual B
_ would have had no first hand knowledge of it. s l

M
., e. The RRI interviewed Individuals C and D who were the Brown and Root quality control inspectors assigned to the concrete -
- placement on December 3, 1978. Both emphatically denied that a any such party took place then or at any other time on site 1 property.
m
- f. The RRI interviewed the Assistant Construction Project Manager relative to Brown and Root policy for construction
- ( employees in good standing who became seriously ill for
$ prolonged periods. He stated that after a short period of 1 time, such as a week, they are considered terminated, but 4 subject to rehire if they can return with a medical 1 released-to-work certification.
m
.) g. Utilizing the above mentioned time sheets and current 4 employment records, the RRI identified five individuals Z who may have been involved in the concrete placement 6 -
on December 3,1978, and were no longer employed on the y site. Review of the employment records for these five
- q people indicated a reasonable possibility that contact 4 -
could be established with three of them. The RRI
( interviewed one of these persons over the telephone
( on August 27, 1979. The person indicated that he U had not actually been placing concrete in the form work Z but was in the area. He stated that he was unaware 2 of any party at that time. The only party that he
,.] -
acknowledged took place the day before the Christmas w '
c holiday job shutdown when Brown & Root sent all those
. persons home who wished to do so at approximately
]9 t 10:00 a.m. This event, the RRI was aware of, and is y
( .
j considered a normal event in the construction field.
The person refrained from agreeing to a personal t interview with NRC personnel, apparently because he
] had no knowledge not already given the RRI over the
{g telephone. Attempts to contact the other two persons were without success.

, -l) j INTRODUCTION Comanche Peak Steam Electric Station (CPSES), Units 1 and 2, are under construction in Somervell County, Texas, near the town of Glen Rose, Texas. Texas Utilities Generating Company is the Construction Permit holder with Brown and Root, Inc. as the Constructor and Gibbs and Hill, Inc.
as the Architect / Engineer.
REASON FOR INVESTIGATION As a result of allegations in regard to the quality of construction at the CPSES facility by a former Quality Assurance inspector, whose comments are
,' contained in the University of Texas at Arlington (UTA) " Shorthorn" newspaper dated July 18, 1979, an investigation was initiated in order to assess their validity and impact on safety-related components and systems.
SUMMARY
OF FACTS
'i
- 1. Allegation No.1 On Wednesday, July 18, 1979, the UTA " Shorthorn" contained a front page article entitled, " Peak Construction called ' Sloppy,' Former Inspecter Cites Defects." The article, by Mike Hinshaw, a UTA staff writer, contained the results of an interview held by the writer with a former Brown and Root employee and currently a student at UTA. In the article, the former 9 employee alluded to examples of the lack of job site coordination. shoddy workmanship, poor supervision, and a waste of construction materials. In
~
- - i~ddi tion , he inoicated that hundreds of defects have not been identified dErine construction of the facility.
i Allegation No. 2:
- During the course of an interview by the IE inspectors with the former
.< employee, he alleged that he was told by an individual (unidentified) that a radioactive material / source (nondescript) was dumped into the Comanche Peak cooling lake.
Allegation No. 3:
The alleger also stated that he was told that improper welds were made on Primary Coolant System, Field Welds FW-19 and FW-20.
Allegation No. 4:
o In addition, he stated that he was told that a 6" check valve weld deficiency had been repaired without correct procedural instructions.

,d CONCLUSIONS
- 1. Allegation No. 1: Matters Identified in Newspaper Article Although the alleger related to instances of what he termed " shoddy" wqrkmanship, poor supervision and poor job site coordination, he could '
_. not provide any additional information, beyond conjer.,ure and hearsay, that would support his allegations of undetected defects in the con-1 struction activities at the Comanche Peak facilities.
- 2. Allegation No. 2: Allegation that Radioactive Material / Source was Dumped into the Comanche Peak Lake
$ Although the alleger was requested to have his unidentified source I[ contact the NRC Regional office, no such person has done so. Sources k whose partial identity met the descriptions given by the alleger were 4 interviewed. They had no knowledge of such an event, nor could they g imagine such an event happening without their being aware of it.
4 . .
7 This allegation appears to have no merit.
$ 3. Allegation No. 3: Alleged Impropen Welds on Primary Coolant System Q ,
~
The reference made to Field Welds FW-19 and 20 by the alleger regarding
{
- improper repair appears to be hearsay. The allegation has no merit in D '
that witnesses and records of the repairs do not substantiate improper
?/ repair.
n . 4. Allegation No. 4: Four or Six Inch Check Valves - Disassembly Without
- .# Proper Procedure D
E The witness identified by the alleger was interviewed. The witness
",; stated that the valve in question was a 6" check valve and that pro-
"i per repair and resolution of the initial discrepancy was complete and 1! documented. Furthermore, there is no evidence that would suggest d' that the procedure discrepancy cited by the alleger would have a
- potential detrimental impact on the health and safety of the public.
{
.. Since the witness, who had first hand knowledge of the valve repair, refuted the allegation, the IE inspector concluded that the allegation
, could not be substantiated.

" 2. Investigation
- a. Allegation No. 1: Matters Identified in Newspaper Article O On September 7, 1979, two IE inspectors met with the alleger at ljj .; his apartment on the campus at the University of Texas (UTA),
N . Arlington, Texas. The interview was prearranged through a tele-a phone conversation with the alleger on September 5,1979.
Q .
'.' , In attendance duru.g the interview were guests of the alleger
-, who were introduced as members of an organization known as Citizens
[ for Fair Utility hates.
y
.( The alleger and his guests requested that the interview be tape
( recorded, utilizing a cassette tape recorder and operated by the guests. There were no objections to the request as presented.
The IE inspectors identified the " Shorthorn" article as the specific area of concern to the IE Regional Staff. Particular reference was made to the last few paragraphs which state:
e
" Asked if there's a possibility defects .in Comanche Peak construction have not been caught, the alleger said yes.

31 "'It goes all the way across the board ' he said, , 'from piping jl , systems to electrical systems to electronic systems.'"
j
- Findings G '
$ The IE inspectors asked the alleger if he could be more specific in g identifying the defects he was alluding to in the article. He responded with an affirmative statement and proceeded in relating, quite emphat-t ically, numerous incidents that involved, in his opinion, work activi-ties being done by unqualified and unconcerned workmen. Subjects
'[s
- alluded to by the alleger included rigging, protection of installed I equipment, setting of diesel generator components, control room panel 1 discrepancies, etc. However, aside from material wastes in each of J the incidents related by the alleger he acknowledged that, in every case involving safety-related components, corrective action and/or 1l measures were taken to his satisfaction and that what he may have
& considered as " defects" did not go uncorrected. He further acknow-( ledged, that despite his frustrations in accomplishing his assign-ments, he was functioning as the job description dictates as a 4',' Quality Assurance inspector.
{ b. Allegation No. 2: Radioactive Material / Source was Dumped into the Coranche Peak Lake Reservoir In addition to the matter identified in paragraph 3 above, the alleger stated that an Equipment Dispatcher (whom he knew personally,

a but refused to identify) told him that, sometime between j the period September 1978 and November 1978, the dispatcher had g received an urgent telephone call from the warehouse area, possibly Westinghouse, "to dispatch a truck and cherry picker ASAP."
The dispatcher responded accordingly. After some unspecified time lapse, the equipment operators returned and told the dispatcher that they had just dumped nondescript containers or objects marked
" Radioactive" into the lake. .
/ The alleger could be no more specific than that stated above. He 9 insisted on not identifying his source of information, but he y did agree to contacting the person and attempting to encourage the person to contact the NRC Regional office.
} Findings
-m g (1) Interview with Individual "B" - Equipment Dispatcher j
j Individual "B" was interviewed by telephone September 18, 1979.
A e Individual "B" acknowledged being one of the Equipment Dis-y patchers during the period September 1978 through November 1978.
g Individual "B" stated that the incident, related to by the f4 alleger was unidentifiable to Individual "B", however, Indivi-dual"C",als;oanEquipmentDispatcherduringthesametime 4 span, may have some knowledge concerning the alleged event.

- On September 20, 1979, through information provided by
.; Individual "B.", Individual "C" was interviewed telephonically.
Q i Individual "C" acknowledged employment as an Equipment j ;, Dispatcher during the time frame indicated by the alleger.
? Individual "C" could not recall such an incident or event
) alluded to by the alleger. Individual "C" indicated that such an' incident would be remembered and would have been 3 known to Individuals "B" and "C". Furthermore, given the if situation described,no other individuals would be dispatching j the equipment involved other than individuals "B" and "C".
1 j The allegation appears to have no merit.

- c. Allegation No. 3: Improper Welding / Repair Process (j
F '
The alleger was asked by the IE inspectors if he had knowledge
,? of any " defects" in other areas that he was aware of that went y uncorrected. He stated that a welder (whom he would not identify) 9 told him that he, the welder, improperly repaired a Steam Genera-
.g tor-to-Reactor Coolant Pump weld during a field weld repair.
The alleger stated that the field weld was either FW-19 or FW-20.

n .
0, 3 Asked if he could be more specific concerning the defective repair, the alleger stated that he was not that familiar with the welding process, but that the matter involved grinding through the stain-less material into the carbon steel, thereby contaminating the stainless with carbon. The IE inspectors informed the alleger that follow up would be performed in regard to the matter.
. The alleger further stated that Individual "A" would be a knowledg'eable witness concerning this matter.
Findings
}
Interview with Individual "A" During the interview with Individual "A" on September 12, 1979, he
[l stated that with reference to field welds W-19 and W-20, he had 7 monitored.the repair activities of the specific welds on a daily basis. To his knowledge, there was no area of repairs that would y( have penetrated into the carbon steel material. The work was y completely controlled by the on-site Westinghouse Representatives
+ who worked closely with each repair. Repair procedures were h developed by the Westinghouse, Pittsburgh office. All work was a
done properly and all defects were properly removed and properly documented. Individual "A" stated that he could not agree with
$ the alleger. :
.~.
In addition, during a routine on-site inspection conducted j October 11, 1979,l/ the IF. Resident inspector reviewed yj the record documents and radiographs of the two field welds,
{ !- W-19 and W-20 during his review of the piping installation i activities. There were no discrepadcies observed.
This allegation could not be substantiated.
Y .
- d. Allegation No. 4: Disassembly of 4" (or 6") Check Valve Without a Procedure An additional matter, specifically identified by the alleger,
,;. involved a repair to a weld that required, as he stated, "The
.x valve body disassembly in order to accomplish the proper repair."
k He related that a 4" or a 6" stainless steel check valve, located in the borated water system, in the area of the component cooling system, had a Nonconformance Report (NCR) written against the
- weld. The NCR indicated that the inside surface of the weld had a not been properly purged during welding and there was evidence
., of oxide on the inside surface. The alleger further stated that, although the inside surface of the weld was correctly repaired by grinding, there was no evidence that a written procedure was used in dismantling the valve: A repair that he contends could only have been accomplished by dismantling the valve body. The alleger specifically identified Individual "A" as the QC inspector with first hand knowledge of the specific uncorrected " defect."
