Nuclear Reactors in Space and the California Nuclear Disaster of 1959

Santa Susana Nuclear Disaster America’s China Syndrome, nuclear cloud spread over Simi and San Fernando Valleys

With the recent press about placing a nuclear reactor on the moon, the environmentalists are reacting to this as if it was a new thing. Neil Armstrong armed a nuclear reactor on the Moon during the Apollo 11 landing which is still in operation on the moon. It is used as a measuring device to measure the distance from the earth to the moon and thus help in navigating in space.

Boeing and Atomics International developed the SNAP reactors at Santa Susana which is in the hills just south of Simi Valley. One of the reactors melted down in 1959 causing the largest and most deadly nuclear accident in US history if you don’t count the nuclear tests. Here is a documentary explaining what happened when the nuclear reactor, the salt cooled reactor melted down and exploded causing a radioactive cloud to encompass Simi Valley and across San Fernando Valley. There was no containment, no shielding.

Also they burned radioactive waste so that it would be dispersed on the wind because the red tape made it “impractical” to bury it properly in disposal sites. Note that again this smoke was deposited over Simi and San Fernando Valleys.

4 reactors blew up over the course of many years of the SNAP reactor project. The reactors were being developed for spacecraft and airplanes. The airplane engine program was halted when the military decided it was a bad idea because if a plane crashes, we would have just given the enemy a working nuclear reactor.

Film: First Nuclear Reactor In Space 71502
From Internet Archive:
“Made in 1965 by the U.S. Atomic Energy Commission, this rare film discusses the design of SNAP-10A, an experimental nuclear reactor launched into space in 1965. The Systems Nuclear Auxiliary Power Program (SNAP) reactor was developed under the SNAPSHOT program overseen by the U.S. Atomic Energy Commission.

SNAP-10A was launched from Vandenberg AFB by an ATLAS Agena D rocket on April 3, 1965 into a polar low Earth orbit altitude of approx. 1,300 km. Its nuclear electrical source, made up of thermoelectric elements, was intended to produce over 500 watts of electrical power for one year. After 43 days, an onboard voltage regulator within the spacecraft — unrelated to the SNAP reactor — failed, causing the reactor core to be shut down, after reaching a maximum output of 590 watts. The reactor was left in a 700-nautical-mile (1,300 km) earth orbit for an expected duration of 4,000 years. In November 1979 the vehicle began shedding, eventually losing 50 pieces of traceable debris. The reasons were unknown, but the cause could have been a collision. Although the main body remains in place, radioactive material may have been released. ”

“The first nuclear power system in space was SNAP 3B, a 2.7-watt radioisotope unit fueled by Pu [Plutonium], which was launched in June 1961. The first reactor power system in space was SNAP 10A, a 500-watt unit, which was launched m April 1965. To date, five radioisotope units with power levels up to 25 watts and one 500-watt reactor unit have been used in the U. S. Space Program.” page 19

SNAP 27 Nuclear Reactor for NASA’s Apollo Missions

Re-entry vehicle for nuclear fuels

NASA planned on regular missions to fuel a space station where they would send nuclear fuel up to orbit and back down again. This involved creating a device that could land and safely return the fuel elements of a reactor without breaking. This led to the creation of the Space Shuttle. The question is how much nuclear materials were on the Space Shuttles that crashed to the earth and should the local populations of the crash sites be concerned?

Burbank CA Nuclear Accident January 18 1968 Placing a Demon Core on a Lathe

US. Nuclear Corporation in Burbank California had a problem, without any authorization they decided to try to remove the outer casing of a Plutonium Beryllium device that produced Neutrons, a DEMON CORE that was used for training in the US Navy for sailors to train to find atomic bombs and this training was on every ship and base including at Treasure Island.

They placed the core onto a Lathe which is used to spin wood or metal to make rounded cuts into objects, just as if you were to make a staircase knob, you cut into it as it spins to make rounded objects. So naturally they decided to do this with the most dangerous thing in the world a Demon Core of Plutonium and Beryllium.

When the Atomic Energy Commission was tipped off about this incident by an anonymous source they came into the facility where the US Nuclear Corporation employees had just bought an industrial vacuum cleaner to clean up the site. They also failed to mention the accident to the AEC as required by law (see below)

Yeah that would not cut it.

The Demon Core was made popular in the movie “Fat Man and Little Boy” which combined two separate incidents where the scientists at Los Alamos were showing off and caused fission to take place killing in each case the show off scientist. It should be noted that spinning plutonium at high speed is not something that you want to do.

The Pu-Be core was made with pellets of Plutonium and the Berylium reflects the neutrons so you can create measured levels of neutron radiation, the radiation of fission found in nuclear reactors and atomic bombs. The US Navy Radiological Defense Lab had two of these devices as of 1960 which were about the size of a casing for a old movie projector and they used it to bombard ships with it to see how far into a ship the neutron radiation would penetrate, in order to make ships safer. When they turned it on they made sure everyone was in a separate building in shielding to protect themselves from the radiation. Not the public, just them. It is the same radiation found in a nuclear power plant or a nuclear detonation.

US Nuclear Corporation decided all on their own without any authorization to divide up the Plutonium into smaller amounts to make more devices.
