10 CFR PART 21 REPORT REGARDING FAULTY RESISTANCE TEMPERATURE DETECTORS |
| | | |
The following text is a portion of a facsimile received from PYCO, Inc.:
"A deviation has been detected in that a limited number of 200 OHM DUPLEX RTD assemblies have been fabricated by PYCO using THIN-FILM RTD sensors instead of the WIRE-WOUND RTD sensors specified for the assembly. RTD assemblies fabricated using wire-wound sensors have been tested and qualified by PYCO for nuclear use under our nuclear qualification test program. RTD assemblies fabricated using thin-film sensors have not been tested by PYCO to IEEE-323 and IEEE-344 requirements."
"Externally, thin-film and wire-wound RTDs have the same physical appearance, shape, and electrical characteristics. Both the wire-wound and thin-film sensors meet the requirements of the International Industrial Standard IEC-75 1, 'Industrial Platinum Resistance Thermometer Sensors'."
These RTDs have been sold to Carolina Power and Light and South Carolina Electric and Gas for use at the Robinson, Brunswick, and Summer plants.

Re: | 10 CFR PART 21 - Notification of Deviation |
PYCO
PENNDEL, PENNSYLVANIA 19047
215-757-3704
As required by 10 CFR Part 21, the following information is to provide notification of deviation in connection with certain 200 OHM duplex Resistance Temperature Detectors (RTD's) supplied to Carolina Power & Light - Robinson Plant and Brunswick Plant and South Carolina Electric & Gas - V.C. Summer Station:
1. | Name and Address of individual informing Commission: |
| Mr. John V. Metzger Jr. - President & CEO - PYCO Inc. 600 E. Lincoln Hwy. Penndel, PA 19047 |
2. | Basic Component Supplied: |
| - 200 OEM duplex Resistance Temperature Detector (RTD) Assemblies
- PYCO Pan Numbers/Customer Part Numbers - See Attachment A
- Customer Purchase Order (PO) - See Attachment A
- PYCO Serial Numbers (S/N) - See Attachment A
- PYCO Shop Order (SO) - See Attachment A
|
3. | Identification of the Firm supplying the basic component |
| PYCO Inc, 600 E. Lincoln Hwy. Penndel, PA 19047 |
4. | Nature of Deviation |
| A deviation has been detected that a limited number of 200 OHM DUPLEX RTD) assemblies have been fabricated by PYCO using THIN-FILM RTD sensors instead of the WIRE-WOUND RTD sensors specified for the assembly. RTD assemblies fabricated using wire-wound sensors have been tested and qualified by PYCO for nuclear use under our nuclear qualification test program. RTD assemblies fabricated using thin-film sensors have not been tested by PYCO to IEEE-323 and IEEE-344 requirements. |
| Externally thin-film and wire-wound RTD's have the same physics appearance, shape and electrical characteristics. Both the wire-wound and thin-film, sensors meet the requirements of the International Industrial Standard IEC-751, "Industrial Platinum Resistance Thermometer Sensors". |
5. | Date Detected: |
| January 25, 1999 - Completion of Engineering Evaluation Based on a query from our Purchasing Department to our supplier, it was identified that 200 OHM duplex Thin-Film RTD's were supplied for an open Purchase Order. |
| PYCO utilizes WIRE-WOUND RTD's for Nuclear use. Our Purchasing Department notified our Quality Assurance Department. |
| Quality requested an evaluation of the acceptability of the Thin-Film RTD's for nuclear use. The research was completed by our Engineering Department. PYCO High Reliability RTD's were qualified for nuclear applications through type testing in accordance with our nuclear qualification test program. All RTD assemblies qualified by the tests were fabricated using wire-wound RTD sensors. Thin-Film RTD assemblies have not been tested by PYCO in our nuclear qualification test program to equipment qualifications as defined in IEEE-323 and IEEE-344, therefore Engineering finds the Thin-Film RTD sensors unacceptable for use in fabrication of Nuclear RTD assemblies at PYCO. |
6. | Location of Components: |
| A. | Known locations of nonconforming assemblies: |
| | 1. | Carolina Power & Light H B Robins Steam Plant Highway 151 and SC 23 Hartsville, SC 29550 |
| | 2. | Carolina Power & Light Brunswick Steam Electric Plant NC Highway 87 North Southport, NC 28461 |
| B. | Potential locations of nonconforming assemblies |
| | 1. | South Carolina Electric & Gas V.C. Summer Station Highway 215 Jenkinsville, SC 29065 |
7. | Corrective Action: |
| A. | Identify 200 OHM Duplex RTD assemblies supplied to nuclear utilities Activity Completed 02/04/99 |
| | - Completed review of Nuclear QA Documents, for all projects
- Attachment A identifies the "Known and Potential" assemblies using the Thin-Film 200 OHM duplex RTD sensor.
|
| B. | Review PYCO Purchase Orders to supplier and identify PO's with thin-film RTD's by supplier part numbers. |
| | Completed 01/27/99 |
| C. | Notify nuclear utilities affected by the deviation. |
| D. | Contact nuclear utilities to identify existing status (stock, in-service, out-of-service) of PYCO assemblies supplied with a 200 OHM Duplex RTD. |
| E. | Generate a checklist to track replacement of nuclear utility stock and inservice 200 OHM duplex RTD elements manufactured by PYCO as identified in Attachment A. |
| F. | Review all applicable PYCO procedures for RTD sensors in connection with procurement, receiving and manufacturing. |
| G. | Generate Sales Orders for replacement of customer identified in-stock and in-service 200 ohm duplex RTD elements manufactured by PYCO as identified in Attachment A. A. |
8. | Advise Related to Deviation: |
| A. | The deviation identified is limited only to 200 OHM duplex RTD assemblies as identified in Attachment A, KEY-A. Assemblies identified in Attachment A, KEY-B indicate that a potential exists that the 200 OHM duplex RTD sensors used in the fabrication of the assemblies may be thin-film rather than wire-wound. |
| B. | All other RTD assemblies fabricated by PYCO, including 100 OHM platinum simplex and duplex RID's, meet the requirements of IEEE-323 and IEEE-344- |
| C. | As per manufacturer's documentation, both the wire-would and thin-film RTD sensors meet the requirements of International Industrial Standard IEC-751, Industrial Platinum Resistance Thermometer Sensors". |
| Sincerely, John V. Metzger Jr. - President & CEO PYCO Inc. |
