ENS 41033 | 9 September 2004 16:10:00 | The following information was received from Texas Department of State Health Services: At approximately 8:45 a.m. the gauge operator had just completed a density test on the site of Wheatley High School, where a new high school is being constructed, when a bulldozer, belonging to another contractor working at the job site, made a sudden and unexpected move toward the operator, who was performing calculations beside the gauge. During the movement the bulldozer operator dropped the blade of the vehicle which impacted the Troxler Model 3430, Serial No. 25129 moisture density gauge. The gauge was crushed with damage to the housing. The gauge contained two sealed sources: Cs-137, nominal 8 millicuries, Serial No. 75-7305 and Am-241/Be, nominal 40 millicuries, Serial No. 47-21337. The sources were not damaged nor leaking. The gauge control rod was in the up and locked. A survey of the area determined that no leakage where the gauge was crushed or to the blade of the bulldozer. The gauge was transported to Component Sales and Services (L02243-000) for leak testing and determination of possible repair. The gauge was determined to be not repairable. The gauge was transferred to Component Sales and Services for disposal. The gauge was last leak tested on April 4, 2004, with negative test results. Texas Incident No. I-8161. |
ENS 40864 | 12 July 2004 14:38:00 | After performing services to determine the oil/water contact interface and the gas/oil interface levels the wireline with the source was being retracted. The wireline was attached to 1 11/16" tool in the salt dome. During retraction, the source evidently got hung on entry to the hole to the surface. It is felt that the crew was inattentive or possibly did not use proper procedure. The 'stuck' source broke loose of the wireline at the established weak point of connection between the tool and the wireline. Retrieval of the source is deemed unrecoverable. This is the second incident of this type in the same field. The source is a Gulf Nuclear, Model CSV-F74, Cs-137, 100 millicurie source. The probable depth of this source is estimated at approximately 4,000 feet. Investigation on site continues. A written report will be submitted to this Agency (Texas Department of Health). Texas Incident No.: I-8142 Event Location: Bryan Mound Strategic Petroleum Reserve, Brazoria County, Texas, Well # BM 104B |
