On July 10, 1951, Ground was broken on the first building in the facility. A 4-square-mile (10 km 2) site about 15 miles (25 km) northwest of Denver on a windy plateau called Rocky Flats was chosen for the facility. The AEC chose the Dow Chemical Company to manage the production facility. History 1950s Undated aerial photograph looking down on the plant from above.įollowing World War II, the United States increased production of nuclear weapons. However, a protectiveness deferred determination was made for PFAS. The latest Five-Year Review for the site, released in August 2022, concluded the site remedy is protective of human health and the environment. Environmental Protection Agency, and Colorado Department of Public Health and Environment review environmental data and other information to assess whether the remedy is functioning as intended. The Refuge (also known as the "Peripheral Operable Unit") was determined to be suitable for unrestricted use. Department of Energy, and (2) the Rocky Flats National Wildlife Refuge, owned and managed by the U.S. The site of the former facility consists of two distinct areas: (1) the "Central Operable Unit" (including the former industrial area), which remains off-limits to the public as a CERCLA " Superfund" site, owned and managed by the U.S. Four groundwater treatment systems were also constructed. The cleanup effort decommissioned and demolished over 800 structures removed over 21 tons of weapons-grade material removed over 1.3 million cubic meters of waste and treated more than 16 million US gallons (61,000 m 3) of water. Ĭleanup began in the early 1990s, and the site achieved regulatory closure in 2006. At the time, the fine was one of the largest penalties ever in an environmental law case. Operators of the plant (Rockwell) later pled guilty to criminal violations of environmental law. Plutonium pit production was halted in 1989 after EPA and FBI agents raided the facility and the plant was formally shut down in 1992. Atomic Energy Commission (AEC), succeeded by the Department of Energy (DOE) in 1977. Operated from 1952 to 1992, the complex was under the control of the U.S. The facility's primary mission was the fabrication of plutonium pits, which were shipped to other facilities to be assembled into nuclear weapons. manufacturing complex that produced nuclear weapons parts in the western United States, near Denver, Colorado. Worker holding plutonium "button" in glove box Precision plutonium foundry mold, 1959 Room damaged by 1969 Rocky Flats Fire Control panel, Critical Mass Laboratory, 1970 I don’t want to hijack this thread - I’m sorry if I did, I’ll leave you to your regularly scheduled broadcast - but, one last time.39★3′N 105☁2′W / 39.89°N 105.20°W / 39.89 -105.20 The situation is made a little more confusing, because although Nuke 11 can read and pass through the B-Stream that chromaticity metadata, it’s actually of a specific type (vec2) of Metadata that isn’t supported on the Metadata edit node. … but if you’re not, or if you’re not sure, please don’t render “as ACES” unless you’re certain! I have a ticket in with Foundry about this, and I think they’re gonna, like, include a tooltip to warn people against just blindly ticking that box… Which is fine, if you’re certain that you are actually writing out AP0… The write node, if you check on “Make ACES-compliant” or whatever it’s called, it will indeed write to the constrained ACES container (I think) but it also writes out EXR/chromaticity metadata as AP0. Not 100% on topic, but a word of warning about Nuke 11 and ACES: If anyone has any suggestions it would be much appreciated. Writenode - colspace - ACES-ACEScct/ exr with ‘write ACES compliant EXR’ checked on. Maya layer (tiff seq as it’s an outline only renderable by Maya software) - colspace - Input-Generic-sRGB Here is my nuke setup - I must be making an error hereįootage read node - colSpace - ACES-ACEScct I can get the footage in and out of Nuke without any change, and I can composite my layers but when I output the composite and send it to the post facility, the 2 things arent balanced. I am working on an HDR monitor in Nuke11.1 The summary of the task is compositing 3D renders from Maya over HDR footage provided in an ACEScct exr sequence. I’m researching and reading what I can but wondered if somebody could help me with a few basics? I need to test an ACES pipeline in Nuke for an HDR delivery and I’m a generalist at a small studio - in no way an expert in colour and this is my first encounter with HDR.
