Subject: Fuel Nozzle Tip 10 CFR Part 21 - Interim Reports

Gentlemen:

The following provides a status of activities and corrective actions associated with the subject 10 CFR Part 21 that have taken place since the initial report dated April 5, 1991. Several interim reports have been delivered to Mr. Walter Haass by telephone since that date.

A meeting took place on was being performed by

June 14, 1991 to review the status of analysis that Houston Light and Power.

DISCUSSION:

1. Data gathered from tests performed by HL&P was reviewed during the meeting. It was determined that there are several attributes that contribute to the failed fuel nozzle tips. However, not all of the attributes are present in every failure. Those that contribute to fuel nozzle tip failures (i.e. cracked in operation, cracks identified during 10 CFR Part 21 investigation, failed dimensional inspection performed at Haynes to support 10 CFR part 21 investigation) include:

Page 2 • QCG-8309

July 23, 1991

0 Ligament thickness at the tip. "* Ligament thickness at the base. "* Ligament area in square inches. "* Ratio of case hardening depth to core size. * Engine induced stress and clogged injector holes (isolated

occurrence). Manganese sulfide inclusions in the base metal (isolated occurrence).

2. It was suggested that the nitride depth be minimized and possibly eliminated.

Subsequent to the Houston meeting this subject was addressed to Mr. Bill Morton of Hayes Corporation Engineering. He stated that the nitride operation is required for improved wear characteristics and hardness of the seat. He indicated that it could not be eliminated.

3. Current Haynes process controls were discussed. They perform a first part destructive test after set up of the nozzle fuel holes drilling process. In addition they perform 100% bore scope examination of the fuel nozzle tips; and, inspect them with a special gauge to ensure that the location and angle of the fuel holes is within tolerance.

4. HL&P personnel stated that the NRC had visited them during the previous week. An isolated failure has been detected in lot number 150009. This went undetected during the eddy current NDE that was performed by HL&P. Discussion with the NRC personnel and application of a conservative approach has prompted HL&P to remove all fuel nozzle tips from stock that fall into the 1500xx lot number series. The following lots have been removed by HL&P.

150003 removed this year (No failure noted) 150004 removed this year (No failure noted) 150006 removed this year (Generic failure) 150008 removed earlier (Generic failure) 150009 removed this year (Isolated failure) 150010 removed this year (Isolated failure)

001110 removed this year (No failure noted) 001124 removed earlier (Generic failure)

Page 3 QCG-8309 July 23, 1991

Thirty-six nozzle tips were selected from various lot numbers and transmitted to Haynes Corporation for inspection. Haynes Corporation was asked to use tool gauge #44-703039 to verify the dimensional location of the fuel port holes. The inspection took place on June 14th, 1991 and was witnessed by Mr. Corliss U. Laisure, a contract auditor that works for Cooper-Bessemer. The attached report documents the results of that inspection. It is noted that all fuel nozzle tips from the 150006 lot failed the dimensional inspection. In addition, one fuel nozzle tip from lot number 150003 failed the inspection. The gauge was introduced after manufacture and deliver of the failed nozzle tips.

A tool gauge patterned after the one used by Haynes Corporation has been ordered by Cooper-Bessemer to verify the dimensional location of the fuel port holes. It's usage will be incorporated into appropriate quality control receiving inspection plans.

Cooper-Bessemer has performed an investigation to identify and locate all fuel nozzle tips (i.e. part number 2-50F-003-023) and holder assemblies (i.e. part numbers KSV-13-2A#4 and KSV-13-2A#6) purchased from Bendix Corporation and/or Haynes Corporation. A total of 2417 fuel nozzle tips were identified by CES serial numbers. 197 Of the 2417 were not traceable to a specific customer. This is explained by the fact that Cooper-Bessemer has delivered 26 commercial KSV engines to various customers. Fuel nozzle tip traceability is not maintained for commercial customers.

Cooper-Bessemer has a high degree of confidence that the attached investigation results capture the total population of fuel nozzle tips delivered to nuclear customers.

Further activities relative to determination of the full scope of the problem are being considered by involved organizations. As corrective action plans/recommendations are further developed a status report will be forwarded to you.

Sincerely,

Controller 7!

Inter-Office Correspondence

Date: June 21, 1991

To: K-6e Haynes Corporation

From: Corliss U. Laisure

Subject: QCG-9095 Cooper Energy Services Purchase Order 3421N1537

Ref: QCG-9018

Surveillance over performance of the activities required by

the referenced purchase order was performed on June 14, 1991.

Requirements of the surveillance were basically to observe the

gauging of the fuel port holes in 36 nozzle tips using tool

gauge #44-703039, recording of results, and maintenance of

serialization of the individual tips. The following personnel

were contacted during this surveillance:

Mr. Dave Langford, Quality Control Manager Mr. Bill Morton, Senior Engineer Mr. Kurt Leutz, Customer Service Mr. Don Moore, Senior Inspector

Gauging of the nozzle tips was performed by Mr. Langford and

Mr. Morton.

Nozzle tips were manufactured to Drawing 10-375927A, "Blank,

Spray Nozzle Body Type N4SE". This drawing was created by The

Bendix Corporation, Electrical Components Division, Sidney,

New York, and was approved 7-25-75. The drawing specifies the

three fuel port holes be concentric with the center bore of

the tip on a circle with an "0.875" diameter. Fuel port holes

are bored at an angle of 5 degrees 5 minutes to the centerline

of the center bore. True position tolerances are used in the

manufacture and gauging of the fuel port holes.

Each nozzle tip was removed from its plastic bag and was

gauged using the specified gauging tool (Tool No. 44-703039).

OCG-9095 June 21, 1991 Page 2

The tip lot number (Haynes lot number), identification

information on bag, including HL&P exam number and results of

the gauging were recorded on the data sheets provided. Upon

completion of the gauging, the nozzle tip was returned to its

original bag. When a bag contained more than one nozzle tip

an HL&P exam number was arbitrarily assigned to each one and

marked on the tip to correlate each tip with the data. A copy

of the data sheet is attached.

All nozzle tips from Lot Number 150006 failed this inspection.

In all cases with this lot, the gauge failed to go into all

three of the fuel port holes. Visual examination during

gauging indicates the holes are to close to the center bore as

noted on the data sheet.

One of two nozzle tips from Lot Number 150003 failed this

inspection (HL&P Exam Number 102). The gauge failed to go in

two of the three fuel port holes. As noted on the data sheet,

visual inspection indicates these fuel port holes are to far

from the center bore.

Both nozzle tips from Lot Number D87001 passed this

inspection, however, the gauge fit snugly in all holes in the

tip identified as HL&P Exam Number 211.

Tool gauge number 44-703039 was manufactured to drawing number

44-703039 dated 11-1-88 and is identified within the Haynes

Corporation calibration control system as functional gauge

number 54910. Calibration of this gauge was checked. The

gauge was entered into the Haynes Corporation calibration

control system on 11-13-89 and is on a 180 day calibration

cycle. Recalibration is due 6-30-91. At my request, three of

the drawing dimensions of this gauge were checked; diameter of

center pin, diameter of fuel port pin, and angle of fuel port

pin bushing with respect to centerline of center pin.

Diameters were checked at three locations along the length on

each pin using a calibrated micrometer. Dimensions were

within tolerance and indicate no taper:

Drawing Dim. Measurements

Gauge Center Pin .3070+/-.0001 .3071 .3071 .3071

Fuel Port Pin .1150+/-.0001 .1150 .1150 .1150

OCG-9095 June 21, 1991 Page 3

Fuel port pin is inserted into the gauge through a hardened

bushing at an angle of 5 degrees 5 minutes to the centerline

of the tool. This angle was measured by inserting the pin

into the gauge and measuring the limits of the angle of the

pin and the gauge centerline on an optical comparator. (Note:

There is a small amount of play between the pin and the

bushing). This angle measured 5 degrees minimum and 5 degrees

10 minutes maximum.
