Call of Duty: Black Ops II is a 2012 first-person shooter video game developed by Treyarch and published by Activision.It was released for Microsoft Windows, PlayStation 3, and Xbox 360 on November 12, 2012, and for the Wii U on November 18 in North America and November 30 in PAL regions.
Reactor-grade plutonium (RGPu) [1] [2] is the isotopic grade of plutonium that is found in spent nuclear fuel after the uranium-235 primary fuel that a nuclear power reactor uses has burnt up. The uranium-238 from which most of the plutonium isotopes derive by neutron capture is found along with the U-235 in the low enriched uranium fuel of ...
Plutonium recovered from LWR spent fuel, while not weapons grade, can be used to produce nuclear weapons at all levels of sophistication, [25] though in simple designs it may produce only a fizzle yield. [26] Weapons made with reactor-grade plutonium would require special cooling to keep them in storage and ready for use. [27]
Call of Duty: Black Ops is a 2010 first-person shooter game developed by Treyarch and published by Activision. It was released worldwide in November 2010 for Microsoft Windows, the PlayStation 3, Wii, and Xbox 360, with a separate version for Nintendo DS developed by n-Space. Aspyr later ported the game to OS X in September 2012.
Weapons-grade plutonium is defined as containing no more than 7% 240 Pu; this is achieved by only exposing 238 U to neutron sources for short periods of time to minimize the 240 Pu produced. Plutonium is classified according to the percentage of the contaminant plutonium-240 that it contains: Supergrade 2–3%; Weapons grade 3–7%; Fuel grade ...
Call of Duty: Black Ops Cold War is an exemption (comparing to Black Ops 6), utilizing a highly modified version of the Black Ops III and 4 engine. [29] Call of Duty: Vanguard was powered by the same engine used in Modern Warfare and Warzone with enhancements from developer Sledgehammer Games. [30] [31]
Contamination due to 240 Pu is the reason plutonium weapons must use the implosion method. Theoretically, pure 239 Pu could be used in a gun-type bomb, but achieving this level of purity is prohibitively difficult. 240 Pu contamination has proven a mixed blessing.
