Mark 17 Nuclear Bomb
The Mark 17 and Mark 24 were the first mass-produced hydrogen bombs deployed by the United States. The two differed in their "primary" stages. They entered service in 1954, and were phased out by 1957. Design and development Design and development originated when Los Alamos National Laboratory proposed that a bomb design using lithium deuteride with non-enriched lithium was possible. The new design was designated TX-17 on February 24, 1953. The TX-17 and 24 were tested as the "Runt" ( Castle Romeo shot) device during Operation Castle in 1954. After the successful tests, basic versions of the Mk 17 and 24 were deployed as part of the "Emergency Capability" program. The MK 17/24 bombs were long, diameter. They weighed 21 tons. The Mark 17 had a yield of .Gibson 1996, p.92. 200 Mk 17s and 105 Mk 24s were produced, all between October 1954 and November 1955. The Mark 17 and Mark 24 were identical in all respects save for the design of their primary section. They were the largest ...

Nuclear Chain Reaction
In nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235U). A nuclear chain reaction releases several million times more energy per reaction than any chemical reaction. History Chemical chain reactions were first proposed by German chemist Max Bodenstein in 1913, and were reasonably well understood before nuclear chain reactions were proposed. It was understood that chemical chain reactions were responsible for exponentially increasing rates in reactions, such as produced in chemical explosions. The concept of a nuclear chain reaction was reportedly first hypothesized by Hungarian scientist Leó Szilárd on September 12, 1933. Szilárd that morning had been reading in a London paper of an experiment in which protons f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashland, Nebraska
Ashland is a city in Saunders County, Nebraska, United States. The population was 2,453 at the 2010 census. History Ashland is located at the site of a low-water limestone ledge along the bottom of Salt Creek, an otherwise mud-bottomed stream that was a formidable obstacle for wagon trains on the great westward migrations of the late 1840s and 1850s. The Oxbow Trail, a variant route of the Oregon Trail, ran from Nebraska City (on the Missouri River) to Fort Kearny (on the Platte River), where it joined the main route of the Oregon Trail. The limestone bottom of Salt Creek at Ashland made it an excellent fording site. Ashland was established in 1870 and named after Ashland, the estate of Henry Clay. Today, Ashland benefits by its proximity to Interstate 80 and the cities of Omaha and Lincoln. While in some respects Ashland is becoming a "bedroom community" of those much larger cities, it retains a rural character. That coherence as a community, and a 30-minute drive to eithe ...
