Serology unit of the FBI laboratory gathers and analyzes blood samples from a crime scene

Technicians working at the serology unit of the FBI (Federal Bureau of Investigation) laboratory. A technician collects blood sample from a shirt belonging to a suspect. The examiner drops benzidine reagent and dilute hydrogen peroxide into the blood sample in cotton swab. The blood sample turns blue. The examiner writes down notes and cuts a sample from the shirt for microchemical hemoglobin test. He places the sample on the microscope slide. The examiner applies a reagent on the sample in the microscope slide. The slide is warmed before being placed under a microscope. The examiner uses the microscope. Red crystals indicating the presence of hemoglobin found under a microscope. The examiner runs test for origin and blood group of the sample. The examiner also gathers samples from the unstained part of the cloth. The samples are placed on test tubes which are placed on a rack. The examiner marks the locations where the samples were taken in the clothing. The examiner writes notes on his worksheet. Blood serums are added to the samples. The rack containing samples are placed inside a refrigerator overnight. The examiner brings out a vial containing liquid blood sample from the same refrigerator. The liquid blood sample is centrifuged, and samples are gathered for a liquid blood grouping slide. Testing solutions are added to the samples. The slide is agitated to expedite the grouping reaction. The examiner reads the slide through a microscope. The examiner brings out vials of samples from blood-stained fabric gathered the day before. The test tubes are placed on the centrifuged machine. Blood samples on vials are placed in small rack. The examiner determines blood sample to be of human origin. Centrifuged grouping samples are placed in grouping slides to determine blood type. Examiner reads samples microscopically. A technician fills out a worksheet. Law enforcement officers read a laboratory report from the FBI.

Animation shows the mechanism of the core tank in the Sodium Reactor Experiment nuclear power plant

The Santa Susana Mountains in Southern California. The Sodium Reactor Experiment nuclear power plant at the Santa Susana Field Laboratory near Simi Valley, California. Facilities inside the Sodium Reactor Experiment also known as the SRE. A miniature model of the SRE showing its sodium graphite reactor. Miniature pipes show the movement of liquid sodium into the reactor. Animation shows the core tank and the reactor fuel is metallic uranium contained in clusters suspended within the core of the reactor. The animation shows the layers of the core tank, the flow of liquid sodium into the core tank, and a diagram showing the transfer of energy from the core tank to steam plant that produces electricity.

Engineers and scientists working on development work during the construction of the Sodium Reactor Experiment

Atomics International engineers working on test and development work on reactor components during the construction of the Sodium Reactor Experiment nuclear power plant at the Santa Susana Field Laboratory in California, United States. A scientist studies the weight of a metal tube. Scientists study mockup fuel elements irradiated in the thermal column of a research reactor. A hydraulic loop was used to simulate sodium flow conditions on top of a tower. Scientist inserts a hydraulic loop. Sodium flowing as seen from the hydraulic loop experiment. Full scale mockup of the fuel handling system was checked mechanically. A prototype coolant pump being studied using a temperature sodium loop. A scientist pushes some buttons of a machine. Machine gauge measures temperature in Fahrenheit. A scientist in protective suit turns a wheel. Scientists lower heavy tube.

Scientists conduct safety tests ensure the durability of the Sodium Reactor Experiment (SRE) nuclear power plant

Scenes in Brandeis California at the Sodium Reactor Experiment site. A man removes and washes solid uranium slugs contained in rod clusters. The slugs are put on paper towel to dry. Men inspect the rod clusters. A man inserts the slug into the rod. A thin-walled stainless steel jacket encloses the slugs. Chemical compounds travel through glass tubes. Chemicals pour into a retort flask. Sodium potassium medium is used for heat transfer from the fuel slug to the jacket. The bonding material were admitted under an inert atmosphere. A jacket is sealed on each end by a welded stainless-steel plug. Scientists employ ultrasonic inspection. A scientist takes off welding mask. The six outside rods are spirally wrapped with stainless steel wire to prevent the fuel rods from touching each other or the coolant channel. Scientist pulls out a rod wrapped in stainless steel wire. The rod is inserted into the sodium cooler. A man in white inspects the moderator assemblies. Reactor grade graphite is machined into a hexagonal shape before being sealed into the zirconium cans. A machine presses panels of zirconium before the panels are machined into the specified width. A Heliarc welding is used for longitudinal welding. Scientists pull out the filler rod so the seams could fuse together. They carry the rod away. Scientist leak test a moderator can. A scientist inserts a well into an x-ray to check for porosity and contamination. They insert three graphite blocks to comprise the moderator element for each can. Short sections of moderator cans are tested for durability of welded head assemblies. Scientists conduct further safety tests to ensure the durability of the Sodium Reactor Experiment (SRE) nuclear power plant. A scientist uses a wrench. A stainless-steel grid plate near the bottom of the core tank supports and locates the moderator assemblies. The holes space the lower ends of the moderator cans and fuel elements on a triangular lattice. Stainless steel core tank contains the core. A welder welding bottom head. The side of the tank with 3 ring section. The animation shows the layers of the core tank of the Sodium Reactor Experiment. Casting of low carbon steel to form seven rings that comprise the thermal shield. View of the thermal shield of the sodium reactor core tank. Animation shows the rotatable top shield on top of the core tank. Man installs moderator assembly on top of the rotatable top shield. The top shield is filled with dense concrete. Man with sodium pump or modified hot oil pumps. The pump rotates.

Construction of the Sodium Reactor Experiment nuclear power plant in Southern California

The Santa Susana Mountains in Southern California. Bulldozers clear trees in the Santa Susana Mountains. Explosives blasting cleared land to build the foundation of the planned Sodium Reactor Experiment nuclear power plant at the Santa Susana Field Laboratory. Construction workers build the core cavity liner of the Sodium Reactor Experiment nuclear power plant. The core cavity liner of the sodium reactor before concrete is poured to make the foundation. A man welds steel pipes in the outer surface of the core cavity. A large circular hole for the inlet and outlet piping. Workers set up basic structures after the core cavity liner and foundation are built. Some workers are digging near concrete columns. A worker pushes a wheelbarrow. Concrete poured into wheelbarrow.
