The SRE accident occurred in July 1959 when there was an accidental blockage of sodium coolant in some of the reactor coolant channels. This resulted in the partial cladding melting of …

In July 1959, tetralin seeped into the primary coolant system through a pump seal and was decomposed by the high-temperature sodium. The decomposed tetralin clogged several …

Jul 5, 2016 · Workers suspected that radioactivity was leaking from a penetration through the reactor’s top for an instrument monitoring the level of liquid sodium inside the reactor. They …

On July 26th, 1959, the SRE near L.A. shut down due to abnormal temperature readings. It was discovered that tetralin leak had caused coolant blockages and caused some fuel to thermally …

accident that occurred at the Sodium Reactor Experiment (SRE) in July 1959, and present my views regarding the accident. I begin with several general observations.

• Fission products were released from the fuel into the reactor’s primary sodium coolant • Primary reactor vessel did not fail, but so me gaseous radionuclides escaped into reactor 21

In fact, from July 12 through July 26, 1959, an unknown amount of radioactive gases were intentionally vented to prevent the Sodium Reactor Experiment from overheating and exploding.

Jul 12, 2019 · That was the next day, July 13, 1959, when a power surge was barely contained. The Sodium Reactor Experiment (SRE) was on its way to becoming the worst partial nuclear …

Jul 12, 2016 · Unit 1 at the Enrico Fermi Atomic Power Plant had a fast breeder reactor cooled by liquid sodium. The operators achieved initial criticality of the reactor on August 23, 1963. An …

An expert opinion elicitation has been used to evaluate phenomena that could affect releases of radionuclides during accidents at sodium-cooled fast reactors. The intent was to identify …
