Based on the information which is publicly available, the Southern California Woolsey fires near LA appear to include the old Santa Susana Field Lab, which, as of a year ago, was reportedly still contaminated with radioactive materials and toxic chemicals.
Update: On November 9, 2018, 1:30 am, the Department of Toxic Substances Control issued an update stating: “The Woolsey Fire burned through a portion of the Santa Susana Field Laboratory (SSFL) yesterday. At this time, it is no longer burning within the SSFL site, and is moving away from the site…” https://www.dtsc.ca.gov/upload/Community-Update-on-Woolsey-Fire-and-SSFL.pdf However, the maps further below suggest that it continued to burn. “Dr. Robert Dodge, President of Physicians for Social Responsibility-Los Angeles, shares the community’s concerns. “We know what substances are on the site and how hazardous they are. We’re talking about incredibly dangerous radionuclides and toxic chemicals such a trichloroethylene, perchlorate, dioxins and heavy metals. These toxic materials are in SSFL’s soil and vegetation, and when it burns and becomes airborne in smoke and ash, there is real possibility of heightened exposure for area residents.” https://www.psr-la.org/woolsey-fire-burns-nuclear-meltdown-site-that-state-toxics-agency-failed-to-clean-up/
Between 1949 and 1988: 10 nuclear reactors and related facilities were operated at ETEC that resulted in chemical and radiological contamination, according to the US EPA: https://19january2017snapshot.epa.gov/www3/region9/superfund/santasusana/SSFL3_08Legal.pdf
This included a partial meltdown of an experimental sodium reactor: https://en.wikipedia.org/wiki/Sodium_Reactor_Experiment
“There’s one thing that everyone agrees on. The Santa Susana Field Lab (SSFL) is contaminated with radionuclides and toxic chemicals.” (See NBC News: “Cleaning Up the Santa Susana Field Lab is All About the Numbers: State regulators, Boeing and community advocates offer different visions for a cleanup” By Matthew Glasser Oct 10, 2017 http://web.archive.org/web/20180807040132/https://www.nbclosangeles.com/news/local/LA-Nuclear-Secret-Santa-Susan-Field-Lab-450098253.html

According to the US EPA: “Between 1949 and 1988, Boeing operated 10 nuclear reactors and related facilities that resulted in chemical and radiological contamination at ETEC”
Although it wasn’t Boeing at the time, the original companies became part of Boeing: https://en.wikipedia.org/wiki/Energy_Technology_Engineering_Center
