Borax Destructive Meltdown Test Contaminated Foot of Soil For Acres

I just heard about the Borax experiments from Atomic Arnie Gundersen on Infowars when he said Fukushima Reactor 3 explosion was a moderated prompt critical explosion like Borax. While I'm concerned that Arnie is being promoted by a pro-enemy disinformation outlet, the Borax failure sounds very much like the Fukushima meltdown scenario where a meltdown led to release of radioactive contaminants 1 foot deep into the soil which is simply covered up by six inches of gravel before they continued business as usual. The design proved the basis for both boiling and pressurized reactor designs, as well as the fatal SL-1 design which also exploded, killing two when it powered up too fast by accident by two people trying to adjust it.

The BORAX Experiments were boiling water reactor experiments conducted by Argonne National Laboratory  in the 1950's and 1960's at the National Reactor Testing Station in Idaho.[1] They were performed using the five BORAX reactors that were designed and built by Argonne.[2]

This series of tests began with the BORAX-I nuclear reactor, which proved Samuel Untermyer II's 1952 theory that a reactor using direct boiling of water would be practical, rather than unstable, because of the bubble formation in the core. Subsequently the reactor was used for power excursion tests which showed that rapid conversion of water to steam would safely control the reaction. The final, deliberately destructive test in 1954 produced an unexpectedly large power excursion that "instead of the melting of a few fuel plates, the test melted a major fraction of the entire core." However, this core meltdown and release of nuclear fuel and fission products provided additional useful data to improve mathematical models. The tests proved key safety principles of the design of modern nuclear power reactors. Design power of BORAX-I was 1.4 megawatts thermal. The BORAX-I design was a precursor to the SL-1 plant, which was sited nearby and began operations in 1958. The principles discovered in the BORAX-I experiments helped scientists understand the issues which contributed to the fatal accident at SL-1 in 1961.
Built in 1954, the BORAX-II reactor proved the principles of pressurized water reactors, with a design output of 6 MW(t).
BORAX-II, modified into BORAX-III with the addition of a turbine, proved that turbine contamination would not be a problem. It was linked to the local power grid and for about an hour on July 17, 1955, it provided 2,000 kW to power nearby Arco, Idaho (500 kW), the BORAX test facility (500 kW), and partially powered the National Reactor Testing Station (after 2004, the Idaho National Laboratory) (1,000 kW). Thus Arco became the first city solely powered by nuclear energy. The reactor continued to be used for tests until 1956.
BORAX-IV, built in 1956, explored the thorium fuel cycle and uranium-233 fuel with a power of 20 MW thermal. This experiment utilized fuel plates that were purposely full of defects in order to explore long-term plant operation with damaged fuel plates. Radioactive gasses were released into the atmosphere.
BORAX-V continued the work on boiling water reactor designs, including the use of a superheater. It operated from 1962 to 1964.

When BORAX-I was intentionally destroyed, the reactor breached containment, causing the "aerial distribution of contaminants resulting from the final experiment of the BORAX-I reactor" and the likely contamination of the topmost 1 foot of soil over about 2 acres in the vicinity.[3] The site needed to be cleaned up prior to being used for subsequent experiments. The 84,000-square foot (7,800 m2) area was covered with 6 inches of gravel in 1954, but grass, sagebrush, and other plants reseeded the area since then. The BORAX-I burial ground is located about 2,730 feet (832 m) northwest of the Experimental Breeder Reactor-1, a publicly-accessible national monument. Since 1987, the United States Environmental Protection Agency has classified the burial ground as Superfund site Operable Unit 6-01, one of two such sites (along with SL-1) at the Idaho National Laboratory. In 1995, the EPA ordered the primary remedy of the burial ground should be: "Containment by capping with an engineered barrier constructed primarily of native materials."[3]

Steam was RELEASED TO THE ATMOSPHERE




dean w notes:


One of the first major tests was performed at the Idaho National Engineering Laboratory. The BORAX test demonstrated that when the reactor core loses water, the reactor automatically shuts itself down. This phenomena is observed because water is both the coolant and the moderator in the reactor therefore when the water is lost the amount of thermal neutrons present decreases. During the test, the BORAX 1 reactor was deliberately destroyed through large reactivity insertion. BORAX was the first test that showed that a light-water moderated reactor could not explode like a bomb because the expulsion of cooling water during the excursion would stop the fission reaction before it reached an explosive rate.
when the water was lost the reactor automatically shut down.. due to the water acting as a moderator and prevented the thermalization of neutrons
