German cargo ship 'Big Lift' | | | | "ABSTRACT: (as reported by licensee's representative) A radiographer and | | Assistant Radiographer were performing radiography at the Port of Tacoma, on | | a German cargo ship Big 'Lift' on March 5, 2003, at approximately 10 PM | | [PST]. The work required the radiographers to use a cherry-picker type | | lifting vehicle to access the work area since the area was about 100 feet | | above deck level. The Radiographer and Assistant were both in the lift | | bucket, 2 feet apart, at the time of the incident. The industrial | | radiographic device (Amersham Corporation Model 660B, containing | | approximately 70 curies of iridium 192) with connected guide tube, | | collimator and control cables had been lifted into position and secured in | | the area of the intended exposure. The exposure device had been made ready | | for the exposure. The operation required the Radiographer and Assistant to | | move the lift as far from the exposure area as possible while extending the | | control cable. | | | | "As the lift was being positioned away from the work area it swayed, this | | startled the radiographer who dropped the control cable. The sway also | | caused the lift's engine to stall. The action of dropping the control cable | | to the extent of its length and resulting sudden stop at the end of the drop | | caused the source to become unshielded. Their survey meter immediately went | | off scale on the highest scale and their alarm-rate meters were alarming. | | | | "It took the radiographers, by their estimate, about 30 seconds to restart | | the [lift] vehicle, move the bucket so they could recapture the control | | cable and secure the source. When they were able to check their pocket | | ion-chambers, they found them off scale. Work was stopped for the day and | | both film badges were sent for processing. | | | | "Results from film badge processing and analysis indicated the Radiographer | | received a whole body exposure of 1600 millirem. This coincided with the | | calculations made by the Radiographer after the incident. The film badge for | | the Assistant indicated an exposure of 1,423,000 millirem. When the badge | | processor was contacted and asked to reanalyze the film they stated they got | | the same exposure. | | | | "Since both radiographers were within 2 feet of each other in the lift | | basket and calculations confirmed that the Radiographer's exposure was 1600 | | milliRem, it appears the exposure to the Assistant was incorrectly | | determined. In addition, the Assistant is not exhibiting any signs of an | | excessive exposure. The company is submitting a report of the incident. The | | Division is performing an investigation. Media, at present, are not | | involved. | | | | "What is the notification or reporting criteria involved? WAC 246-221-260, | | Reports of overexposures and excessive levels and concentrations. | | | | "Activity and Isotope(s) involved? 70 curies of Iridium 192. | | | | "Overexposure? Until the investigation indicates otherwise, the process | | report of the Assistant's film badge indicates a whole body exposure of | | about 1,423,000 milliRem. The over exposure is apparently not real since | | calculations using exposure time, distance and source activity and a second | | film badge, worn by another individual closely associated with the first all | | indicate exposure is unusual but much lower. Staff will investigate." | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |General Information or Other |Event Number: 39670 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: WESTINGHOUSE |NOTIFICATION DATE: 03/14/2003| |LICENSEE: ABB INC |NOTIFICATION TIME: 15:47[EST]| | CITY: PITTSBURGH REGION: 1 |EVENT DATE: 03/14/2003| | COUNTY: STATE: PA |EVENT TIME: [EST]| |LICENSE#: AGREEMENT: N |LAST UPDATE DATE: 03/14/2003| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |DAVID AYRES R2 | | |MARK SHAFFER R4 | +------------------------------------------------+JACK FOSTER NRR | | NRC NOTIFIED BY: HANK SEPP |BRIAN MCDERMOTT R1 | | HQ OPS OFFICER: YAMIR DIAZ |KENNETH O'BRIEN R3 | +------------------------------------------------+ | |EMERGENCY CLASS: NON EMERGENCY | | |10 CFR SECTION: | | |CCCC 21.21 UNSPECIFIED PARAGRAPH | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | 10 CFR PART 21 REPORT REGARDING FAILURES OF ABB CIRCUIT BREAKERS | | | | Circuit breakers manufactured by ABB Inc. and used for Class 1E applications | | by Westinghouse were shipped to the Calvert Cliffs Plant with model 5 | | operating mechanisms installed.
