#SouthernCalifornia #wildfires force evacuations, and one is threatening a #nuclear facility
Evacuations remain in place for fires burning in #Ventura and #Riverside counties. The Sandy Fire in #SimiValley is burning near the #SantaSusanaFieldLaboratory, a former #NuclearReactor site, raising #AirQuality concerns.

Excerpt: "Due to the Sandy Fire’s proximity to the Santa Susana Field Laboratory, a former nuclear reactor and rocket testing facility, officials are conducting air quality monitoring around the fire perimeter.
" 'Monitoring equipment has been proactively deployed to establish background air quality readings and to help assess conditions should the fire advance further into the area,' according to CAL Fire. 'At this time, the fire has not crossed into the Field Laboratory property.'
"Nuclear cleanup continues more than 50 years after a nuclear reactor mishap at the #Rocketdyne site. Fire crews are prioritizing the protection of the facility and the surrounding communities. "

#LAFires Could Transform Former #Rocketdyne Site into #FEMATrailerPark
January 2025
"#Radiation and chemical vapors on 47-acre #CanogaPark site are too toxic for housing, but could be mitigated to safely house residents displaced by January 2025 fires in above-ground trailers.
- Gross site contamination and development encumbrances prohibit residential housing
- Hundreds of #FEMATrailers, mobile homes and even shipping containers could be placed on site safely and temporarily house thousands of #LosAngeles disaster victims [Or maybe a potential #DetentionCenter? Hmmmm...]
- Efforts to clean up polluted west Valley groundwater could emulate 2024 agreement to remediate fouled east Valley aquifer and provide billions of gallons of clean water"The former Rocketdyne Canoga Park facility in the western #SanFernandoValley is so contaminated that it is nearly impossible to build anything on it other than light industry even though a developer wanted to construct homes on the site.
"#Chemicals and #radiation severely contaminate the land and #groundwater in and around the site according to documentation obtained by EnviroReporter.com.
"According to astonishing information never before covered in the media, areas offsite and around #RocketdyneCanoga are hot with high amounts of gross alpha and uranium radiation."

Warum nicht mal einen Raketenantrieb der Wasserstoff, flüssiges Lithium und Fluor verbrennt?
https://www.youtube.com/watch?v=KX-0Xw6kkrc
> The #Rocketdyne tripropellant engine, tested for NASA in the late 1960's may very well be the most dangerous chemical engine ever tested.
Und das brennt dann auch noch so heiß dass Funksteuerung auch keine Option mehr ist.
#Schwefelsäure bei 5000ºK aus einer sich selbst auflösenden Rakete verschießen klingt… äh…
Hydrazin war euch zu sicher, oder?

The story of the #Rocketdyne Tri-propellent test #Rocket Engine.
The SI was over 500 but the engineering challenges were formidable, to say the very least 😳🤦♂️
Have you Hazard Bingo Card on hand and see how many you can cross off before the end of the episode 🫨😣
That anyone was actually so ridiculously stupid enough to test this concept says all you need to know about safety standards in that time period
Not quite the most dangerous Rocket engine concept ever conceived, but it gets close.

The #engine section of a #Delta II #rocket.
The main engine is a #Rocketdyne #RS27A that burns kerosene and liquid oxygen.
On either side of the center engine nozzle, the two yellow and white portions that seem covered in fabric with red openings are #vernier thrusters to maintain attitude control.Get a print or other item at https://heronfox.pixels.com/featured/1-delta-ii-engine-section-heron-and-fox.html

Massive #SantaSusana Lab #Contamination Deliberately Hidden Since 1981
By Michael Collins • on April 30, 2023
"This active conspiracy to deceive the public has lasted 42 years. Thousands of pages of documents have revealed shocking tales of #environmental crimes that are all the more alarming considering that #NASA will leave most of its deadly goo behind, fouling the water and land for hundreds of years to come. That land is now surrounded by over 700,000 residents within ten miles."

During a tour of #NASA’s Kennedy Space Center #KSC, #journalists and #photographers were brought to a room to be shown some hardware. It was completely ignored in favor of the #restored S-3D #rocket #engine. The presentation was derailed, much to the chagrin of NASA’s Press Office.
But really, it was their fault. They basically brought a bunch of magpies into a room with something shiny. What did they expect to happen? For us not to gawk at the #shiny #rocket #engine?
And then they didn’t even tell us anything about it. They just gave their presentation while glaring at the magpies they willfully brought into a room with a rocket engine in the corner.
The S-3D is an #ancestor of many engines. It powered the #Atlas rocket until the Atlas III, the #Saturn I & IB, the #Thor missile/#SLV, and became the #Rocketdyne RS-27 on the #Delta and #DeltaII #rockets.

Why Is the #SantaSusana #Nuclear Accident Still Being Covered Up?
Excavating Six Decades of Buried Secrecy, Neglect, and Flat-Out Lies in the #SanFernando Valley
By Warren Olney, January 13, 2022
"The Field Lab (#SSFL) opened in 1947, at the onset of the Cold War, and the reactor accident happened in 1959. The Atomic Energy Commission (AEC) and a nuclear contractor kept it secret for 20 years, but there was no denying the evidence we revealed on local TV, discovered in AEC archives by the watchdog group Committee to Bridge the Gap.
"Today, that accident is still news, as Gov. Gavin Newsom appears to be backing away from enforcing a cleanup of nuclear contamination that remains on the site. Sixty-three years since the accident, Santa Susana should remind us of the perils not only of nuclear materials but also of our short memories. This story’s hardest lesson is that when dangerous secrets get buried you often have to keep excavating them, over and over.
"Over the years, #residential development moved closer to the Field Lab, but no one ever told the public about the release of radioactive contamination which would remain dangerous for thousands of years. In 1989, a local newspaper reported on secret government studies showing extensive contamination at the site. That drew attention from unsuspecting homeowners, and a community group called the #Rocketdyne Cleanup Coalition sprang up to oppose re-licensing of site facilities. Nuclear operations at Santa Susana finally halted in 1990."

Brandeis-Bardin Groundwater Toxins Hit Historic Highs

#SantaSusanaFieldLab #radiation and #chemicals plague popular Jewish camp as Los Angeles Water Board prepares to end #SSFL surface water testing
"Cesium-137, radium-226, arsenic and mercury" found in "ever-increasing concentrations". Many have hiked in the nearby canyons, "where these readings were found the well-water."
