| AMERSHAM RADIOGRAPHY CAMERA DRIVE CABLE BROKE OFF |
| |
| Radiographers from Calumet Testing Services Inc., out of Griffith, Indiana, |
| were taking radiography shots at NIPSCO Electric Generating Station located |
| in Michigan City, Indiana. They were using an Amersham A424-9 radiography |
| camera with a 660B exposure device. The radiography camera contains a 90 |
| curie Iridium-192 source. The end of the drive cable broke off at the tip. |
| The Radiographer and his assistant placed lead shielding over the tube |
| containing the source. The Radiation Safety Officer (RSO) was informed of |
| this incident and he took extra lead shielding and a extra crank out to the |
| site. On arrival to the site the RSO had extra lead shielding placed over |
| the source. The back of the camera was removed and a 6 to 8 foot retrieval |
| device was used to pick up the exposure tube and drop the source out the |
| front of the tube. The retrieval device then was used to retrieve the |
| source and place it in its stored position in the camera. The RSO stated |
| that this is the second time in the last couple of years where the end of |
| the drive cable has broken off. Film badges of the individuals that were |
| exposed to the source will be read later today. The estimated exposure to |
| the following individuals were taken from their pocket dosimeters: |
| radiographer received 200 millirems, radiographer assistant 40 millirems, |
| person who retrieved the source exposure was 200 millirems and the RSO |
| received 10 millirems. |

| 24-HOUR OPERATING LICENSE NPF-12, SECTION 2 REPORT DUE TO EXCEEDING LICENSED |
| POWER LIMIT |
| |
| "V. C. Summer Station experienced a plant transient as a result of a |
| feedwater heater level transmitter failure. The transient resulted in core |
| power exceeding licensed limit of 2900 megawatts thermal (MWT) at 1531 hours |
| on May 1, 2001. Preparations were underway to reduce power when the |
| feedwater heaters were reset and power stabilized at less than 2900 MWT. The |
| duration of the transient was less than seven minutes. |
| |
| "The loss of feedwater heater string resulted in a lowering of steam |
| generator feedwater supply temperature and subsequent drop in reactor |
| coolant system Tcold (cold leg temperature). |
| |
| "Subsequent investigation by Engineering and Independent Safety analyses |
| Group personnel indicated core power reached 102.7% of maximum power as |
| indicated by core differential temperature (delta T). Core delta T was |
| determined to be the most reliable indication of core power during this |
| transient. |
| |
| " The cause of the feedwater heater level transmitter failure is currently |
| under investigation. No automatic load reduction or other safety actuation |
| occurred." |
| |
| The licensee informed the NRC resident inspector. |

| "NOTIFICATION OF POTENTIAL DEFECT PER 10 CFR 21 K-LINE CONTROL DEVICE CLOSE |
| COIL HAIRPIN RETAINER |
| |
| "On 01/25/01, Grand Eagle Service reported a failure to close of K-Line |
| circuit breaker during 'as found' service testing due to a malfunctioning |
| replacement control device. The cause of the malfunction was determined to |
| be the use of an inadequate hairpin retainer in the control device. |
| Specifically, the retainer on the close coil armature pivot pin becomes |
| dislodged from its slot allowing the pin to wander from the proper position |
| inside the armature. |
| |
| "The cause of this failure was determined to be a design change oversight. |
| In November of 1998, Engineering Change Notice number 5319 was issued |
| specifying a change from hairpin retainer part number 53152C00 to part |
| number 53152D00 in K-Line 708392T## series Control Device assemblies. This |
| change was made in the interest of ease of assembly. For the purpose of this |
| notice, this issue affects only K-Line circuit breakers which have a |
| mechanical 'black box' control device containing an internal close coil. |
| |
| "Corrective action for this incident has been taken. On February 16, 2001, |
| ECN number 5999 was issued reversing the 1998 change and specifying the use |
| of Hairpin Retainer part number 53152C00. All control device Assemblers and |
| Team Leaders were informed of the ECN and trained on the use the correct |
| hardware. All of the D type retainers were removed from the control device |
| assembly station and replaced with the C item. Additionally, all |
| applicable control devices in the manufacturing facility, either installed |
| in production or completed circuit breaker units or in component stock, were |
| pulled and reworked. |
| |
| "This report of defect, once again, is only applicable to K-Line Type |
| circuit breakers with a mechanical Control Device containing an internal |
| close coil purchased between November 1998 and February 15th, 2001. All |
| circuit breakers containing the defective control device are subject to this |
| failure mode. Those control devices should be repaired or replaced as soon |
| as feasibly possible. |
| |
| "This Part 21 report is the second report regarding mechanical Control |
| Devices that has been issued in the last six months. All replacement control |
| devices ordered as a result of the Part 21 report dated December 20, 2000 |
| are subject to this defect if shipped from the Florence, South Carolina |
| manufacturing facility prior to February 16th, 2001. |
| |
| "ABB will notify all customers who purchased this product." |
| |
| HOO NOTE: See previous report #37663. |
