A Report Of The U.S. Atomic Energy Commission: The SL-1 Accident, Phase 3 Pt. 1 of 2
04:17:57 Man at desk introduces film “..first fatal nuclear reactor accident in the United States (03Jan61)...an uncontrolled nuclear excursion...” “All three men performing maintenance were killed.” Phase 1 retrieving bodies etc. Phase 2 determining nuclear safety status...w/ remotely operated equipment. Separate motion picture has been released. Phase 3 was aimed at “what caused the nuclear excursion...” Contract awarded to General Electric. Still photograph showing before accident. Cut-away drawings of reactor building. Photos of post-accident
04:22:31 Film of workers removing pieces & remotely filming etc. Briefing workers before investigating & working. First personnel into building; draining water tank, measuring radiation. Engineers discussing.
04:26:45 Clean up activity ca November 1961. Wearing many radiation badges; face mask; disposable plastic suit over double coveralls w/ dosimeters on suit. Working w/ vacuum cleaner in top of reactor building, cans of high debris removed; large pieces remove. Covering radiation w/ heavy steel plate. Exterior stairwell built to allow access to top.
04:31:21 Cutting ducting, fan etc. for removal; Crane lifting pieces from roof. Men checking equipment for radiation. Digging pit for burial of equipment & moving equipment by hoist & truck & placed in burial trenches; covered w/ several feet of soil.
04:33:29 Boring into core area prior to extraction of reactor. Photos showing reactor room. Trial lift of 13 ton reactor. Cutting hole in ceiling, lifting out out portions & cutting & removing wall sections. Test lift of same size & weight & test hauled in concrete cask. Rubberized canvas placed to wrap vessel as extracted. Photographers. Removing & lowering onto truck & metal top put over.
04:37:27 30Nov61 Truck & cask steam cleaned & truck leaving w/ caravan. Arriving at Hot Shop & backed inside into shop originally used for aircraft nuclear propulsion program. Men discussing next step; large portions of contaminated building removed, cut & trucked off. CU cutting of base & gravel removed by scoop & dump truck. Superstructure removed prior to dynamiting concrete slab on steel supports.
04:41:05 Concrete slab on remaining steel supports prior to dynamiting. Explosion. Bulldozer dragging slab to burial ground. Remaining gravel & steel baseplate removed.
04:42:35 Cleaning adjacent buildings, mopping, vacuuming, brushing & bagging. Dumping into waste pit. Salvageable telephones & equipments taken for cleaning. Hosing of buildings; site ground scraped; hot spots shoveled. Men monitored in steel cubicle to measure radioactivity outside of background radiation. Man w/ chart noting measurements. CU 18 badges on badge belt for Beta radiation. Graph of wholebody & skin exposure.
Environmental Cleanup; Radioactivity; Radioactive; Engineering Problems; AEC; Testing; 1961; Safety;
NOTE: Any continuous 16 minute section sold at per reel rate.
