Cleaning Units manufactured

by The Bahnson

Company for CTI-Nuclear

(CTIN) to be supplied to Carolina

Power and Light (CP8L).

The inspections

as-indicated

below, were conducted

using criteria established

to the

applicable

Ebasco Specification

(CAR-. SH-BE-31),

CTIN Drawings, Seismic

gualification Reports,

and

CPRL drawings, to determine whether the

During the inspection

the following conditions were obser ved:

(1)

The weld requirements for attaching

the High Energy Particulate

Absorption

(HEPA) filter rack (Item 2 on CTIN Drawing 32735A)

to the unit housing are for a continuous fillet weld and an

interrupted

(2-10) flair bevel weld,

(shown in Section

C-C of

the drawing).

Contrary to the above,

both

HEPA filter racks are attached

to

the unit housing with an intermittent (2-10) fillet weld and

a continuous flair bevel weld.

This condition existed

on both

R-2 units examined.

(2)

The weld requirement for attaching

Item 27 to Item 28, both

3" x 3" x 3/16" angle,

on CTIN Drawing 32629 is

a square

bevel

partial penetration butt, welded from both sides,

(shown in

section

Z-Z of the drawing).

Contrary to the above,

the welds attaching

Item 27 to Item 28

are welded from one side only.

This condition exists in four

p1aces

on the

1B-SB

E6 unit examined.

(3)

The inspectors

reviewed the documentation

packages

for the Air

Cleaning Units to determine whether or not the nonconformances

noted above

had been

documented

and evaluated.

There was

no

documentation

to indicate that the nonconformances

had ever been

detected.

The inspectors

informed

CP8L management

that failure to identify

and evaluate

nonconforming welds in purchased

equipment is contrary

to 10 CFR 50, Appendix B, Criterion VII as

implemented

by CPSL

PSAR

section 1.8.5.7.

10 CFR 50.55(f)(1) requires

CP8L to implement the

gA program documented

in the

PSAR.

This is an example of the findings

which led to Potential

U

Weldin

Li uid Penetrant

Examination

The inspectors

selected

a -portion of a weld for reexamination that,

fabrication records

indicated,

had been liquid penetrant

examined

by

Bahnson

as required

by Ebasco specification

CAR-SH-BE-31.

This

reexamination

was

made to determine whether the .surface

was suitable

for liquid penetrant

examination

and acceptable

to the applicable

acceptance

criteria.

The weld selected

was

a portion of the continuous flair bevel weld

attaching

the upstream

HEPA filter rack to the top of the 2A-SA-28-SB

'2

unit. housing.

This examination

was performed

by a"CPSL, Level II,

liquid penetrant

examiner,

using the solvent

removable

method in,

accordance

with,CPSL Procedure

201 Revision 2.

(This was the

same

type of liquid penetrant

examination

performed

by Bahnson - color

contrast,

solvent removable.)

As a result of the liquid penetrant

examination,

the inspectors

observed

the following conditions:

4

c ~

.(1)

The surface

was suitable for liquid penetrant

examination.

s

(2)

An area of lack of fusion at the toe of the weld between

the

weld and the

HEPA filter rack was identified.

(3).

An area of undercut at the fusion line between

the weld and the

HEPA filter rack was identified.

Later measurement,

by a

CP8L

welding inspector,

revealed

the undercut to be in excess of

- 1/64".

(4)

Paragraph

16,,of the

HVAC Addendum A, to Ebasco Specification

CAR-SH-BE-31, "Air Cleaning Units", prohibits any lack of

fusion, and undercut in excess of 1/64".

The inspectors

reviewed

the documentation

packages for the Air Cleaning Units to determine

whether or not the nonconformances

noted in (2) and (3) above

had been

documented

and evaluated.

There was

no documentation

to indicate that the nonconformance

had ever been detected.

The inspectors

=informed CPSL management

that failure to identify

and evaluate

nonconforming welds,in purchased

equipment is contrary

to 10 CFR 50, Appendix B, Criterion VII as

implemented

by CPSL

PSAR

section 1.8.5.7.

10 CFR 50.55(f)(l) requires

COL to implement the

r

Boltin

Visual Ins ection

The inspectors

made

a visual examination of selected

connections

for appropriate fastener material

type, size, traceability,

and

material.

No violations or deviations

were found in this area.

Review of ualit

Records

The inspectors

reviewed the documentation

packages for the 1A-SA-IB-SB

and 2A-SA-2B-SB R-2

MVAC air cleaning units to determine

conformance

with procurement,

storage,

and fabrication specifications,

and

regulatory requirements.

The review revealed

the following conditions:

(1)

Records. for the liquid penetrant

examination

performed

by

- Bahnson

on July 16, 1982,

and partially reexamined

as

described

in paragraph

c, above revealed

the following

statement:

".Item 2 to housing,

Typ. area,

100K, reject

. RM July 16, 1982, Repair Accept July 16, 1982."

It should

be noted that there are

two number

2 items installed in

each

R2 unit and there are welds

on both the upstream

and down-

stream sides of each

item 2, attaching

them

( Item 2) to the unit

housing, that require liquid penetrant

examination,

as specified

by'TIN drawing 32735-A Section

C C.

At the time of this

inspection, it could not be determined whether the above statement

.meant that all of the welds attaching all of the Item 2s to the

housing of the 2A-SA-2B-SB R-2 unit had been repaired or just

'ome of them.

The licensee

indicated that they would investigate

. the above matter and make

a determination

as to the number of

'- welds repai,red.

Pending,

NRC review of the licensee's

investi-

gation, this matter will be identified as unresolved

item

400/84-05-01:

"HVAC Weld Repairs."

(2)

The 2A-SA-2B-SB R2 unit was subjected

to a vigorous receipt

inspection

by CP&L which resulted in the issuance

of DDR-1053.

DDR-1053 accepted

"as-is" all weld defects

including two cracks,

on the 2A-SA-2B-SB R2'unit.

At the time of this inspection the

licensee

could not provide

a justification for leaving the two

cracks uncorrected

in the unit.

Pending resolution of the

above

issue this matter will be identified as unresolved

item

400/84-05-02:

"Cracks in R2

HVAC Unit."

(3)

The "Preventative

Measures"

block of the Corrective Action

Report for DDR-1053 was marked

"NA", Not Applicable, with an

accompanying

note which stated that preventative

measures

were

not applicable

because

the Air Cleaning Unit inspected

and

rejected

was the last unit in production.

No reinspection of

. previously received units of Bahnson

equipment

was initiated.

The inspectors

informed

CP&L management

that failure to perform

adequate

corrective action is contrary to 10 CfR 50, Appendix B, .

Criterion XVI, as

implemented

by

CP&L PSAR section 1.8.5.16.

10 CFR 50.55(f)(l) requires

CP&L to implement the gA program

documented

in the

PSAR.

This is an example of the findings

which led to Potential

Enforcement Action 2.

HVAC Air Handlin

Units

The inspectors

performed detailed inspections, of 17 of the 47 safety

related

HVAC Air Handling Units manufactured

by The Bahnson

Company

'or

CP&L's Shearon Harris Project.

The inspections

were conducted

using criteria established

in the applicable

Ebasco Specification

(CAR-SH-BE-08),

Bahnson

.Drawings (drawing only. available for four

units),

and Seismic gualification Reports to determine whether the

fabrication, receiving inspection,

and storage were-

consistent with applicable drawings,

procedures,

specifications

and regulatory requirements.

All the Air Handling Units inspected

had been accepted

by CP&L.

The Bahnson

Company considers their drawings proprietary

.

information and therefore

CP&L did not have copies of

the drawings.

CP&L did request that The Bahnson

Company

supply drawingS for three units selected

by the

NRC

inspectors,

units AH-15, AK-28, and.AH-85.

The remaining

units were inspected for weld location and joint design

based

on typical weld details contained

on the drawings

for units AH-15, AH-28, and AH-85.

At the time of this

inspection, it could not be determined,

except for units

AH-15, AH-28, and AH-85, with 100K confidence that the welds

listed as missing in the remaining units were required

by the drawings=for the specific unit.

However, the welds

listed as missing

on side panel

frames were typically

required to be welded all the way around

and were actually

only welded on two or three sides.

The licensee

indicated

that they would investigate

the above matter and make

a determination

as to the

number

and location of missing

welds.

Pending

NRC review of the licensee's

investigatiorl,

this matter will be identified as unresolved

item

400/84-05-03:

"Missing HVAC Welds", except for those

welds found missing

on Unit AH-28 (IB-SB) [see para.

6.a.(3)].

(2)

.Inspection of weld quality was based

on Ebasco Specification

CAR-SK-BE-05, Addendum A, "guality Assurance

Requirements

for Nuclear Safety Related

HVAC Equipment", which invokes

AWS 01.1

and specifically prohibits cracks,

crater s, lack

of fusion, and undercut which exceeds

I/64".

As noted in

the listing above there were seven Air Handling Units which

did not meet the acceptance

criteria for welds.

(3)

The inspectors

reviewed the documentation

packages

for the

Air Handling Units to determine whether or not the missing

welds in Unit 28 (1B-SB) and the weld quality nonconformances

in the other units

had been .documented

and evaluated.

There

was

no documentation

to indicate

the nonconformances

had eyer been detected.

The inspectors

informed

CP&L

management

that failure to identify and evaluate

noncon-

forming welds in purchased

equipment is contrary to 10 CFR 50, Appendix B, Criterion VII as

implemented

by CP&L PSAR

section 1.8.5.7..

10 CFR 50.55(f)(1) requires.CP&L to

Review of ualit

Records

(I)

The inspectors

reviewed the Ebasco

procurement specifica-

tion, Bahnson general

arrangement

drawing and Bill-of

Material

(BOM} for unit AH-17 (I-4A-SA) to establish=- material

requi rements.

The Certified Material Test Reports

(CMTR)

or Certificates of Compliance

(COC) supplied with the

documentation

package for the unit were, then compared with

the material

requirements.

The review revealed 'the following

conditions:

(a)

The

BOM and procurement specification were inconsistent

on material

requirements

in the following areas:

- Interior Casing

(Fan and Coil Sections)

Specification

required

20ga

ASTM A240, Type 304.

The

BOM specified

20ga

304 stainless

steel with no ASTM designation.

- Floor (Coil and

Fan Sections)

Specification

required

20ga

ASTM A240, Type 304.

The

BOM specified

10 ga,304 stainless

steel with no ASTM designation.

- Drain Pan Liner Specification required

10ga

ASTM A240,

Type 304.

The

BOM specified

20ga stainless

steel

with no

ASTM designation.

(b}

The following questions

or inconsistencies

resulted

from

reviewing the data

package:

- An Edcomb Metals

COC was for 18-8 Type 304 stainless

steel with no ASTH designator.

- No material

CMTR's or COC's were provided for the..fan

~

.

.

housing which was supplied

by Westinghouse

an'd required

to be

ASTM A283.

- COC's or CMTR's for the following materials,

specified

in the

BOM could not be found;

Unit Casing Exterior - 14ga

ASTM A366

Interior Casing in fan and coil sections - 20ga

Type 304 stainless

steel

-9-

Drain Pan Liner - 20ga Type 304 stainless

steel

- The Ebasco

release for shipment report was signed

and

stated that there were no special

conditions

and deviations

from purchase

contract;

however, there

was

an open

DDR (No. 80-00?0)'nd

attached

correspondence

'permitting shipment with .open documentation

and

without fan motors.

The inspectors

did not identify any violations, but did

inform the licensee that the material substitutions identi-

fied by the

NRC are considered

unresolved

items.

Pending

the licensee's

evaluation

and

NRC review during a subsequent

inspection, this matter will be identified as unresolved

item 400l84-05-04:

"Material Substitutions".

CP8L instituted

a

l00% receipt inspection at the Shearon

Harris Plant site in approximately

September

1982.

Bahnson

supplied air handling units AH-85, AH-86, AH-92, and AH-93

were received after the institution of. the

100K receipt

inspection

program.

The inspectors

reviewed the

CPSL

receipt inspection reports

and accompanying deficiency

documentation

reports.

CPIWL had rejected all the units

for a combination of nonconforming weld quality, weld joint

configuration,

and missing welds.

At the time of the

inspection,

Units AH-85, AH-86, and AH-93 had already

been repaired

and accepted

by CPKL.

However,

CPKL had not

performed

any kind of reinspection

on air handling units

received prior to i'nstituting the 1005 receipt inspection.

The inspectors

informed

CPSL management

that failure to

perform adequate

corrective action is contrary to 10 CFR 50,

Appendix B, Criterion XVI, as

implemented

by CPEL

PSAR

section 1.8.5.16.

10 CFR 50.55(f)(l) requires

CP8l

to

implement the gA program*documented

in the

PSAR.

This is

an example of the findings which Ied to Potential

Enforcement Action 2.

The inspectors

reviewed reports of Ebasco facility evaluations

and Bahnson

commitment to corrective actions

to cited

deficiencies for 19??,

19?8,

1980,

and 1983.

The review

revealed

the following conditions:

The corrective actions

committed to by Bahnson indicated

a

lack of adequate-measures

to prevent'ecurrence

of the

problems;

however; most commitments

were never questioned

by Ebasco

and there

was. no evidence that Ebasco

performed

followup to review implementation of corrective action

until the next facility evaluation

was performed.

The

following areas of Bahnson's

gA program were repetitively

cited by Ebasco

and reflects

a lack of adequate

corrective

action by Bahnson

and

a lack of vendor control by Ebasco:

- 10

-.

- Failure to maintain adequate

vendor program control

for nuclear suppliers

- Failure to maintain adequate

controls of procedures

and

personnel

relating to performance of the quality function

including NDE.

This is an example of. the findings which led to Potential

Enforcement Action 2.
