Nuclear fuel

Nuclear fuel is material used in nuclear power stations to produce heat to power turbines. Heat is created. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission; the three most relevant fissile isotopes are Uranium-233, Uranium-235 and Plutonium-239. When the unstable nuclei of these atoms are hit by a slow-moving neutron, they split, creating two daughter nuclei and two or three more neutrons; these neutrons go on to split more nuclei. This creates a self-sustaining chain reaction, controlled in a nuclear reactor, or uncontrolled in a nuclear weapon; the processes involved in mining, purifying and disposing of nuclear fuel are collectively known as the nuclear fuel cycle. Not all types of nuclear fuels create power from nuclear fission. Nuclear fuel has the highest energy density of all practical fuel sources. For fission reactors, the fuel is based on the metal oxide. Uranium dioxide is a black semiconducting solid, it can be made by reacting uranyl nitrate with a base to form a solid.

It is heated to form U3O8 that can be converted by heating in an argon / hydrogen mixture to form UO2. The UO2 is mixed with an organic binder and pressed into pellets, these pellets are fired at a much higher temperature to sinter the solid; the aim is to form a dense solid. The thermal conductivity of uranium dioxide is low compared with that of zirconium metal, it goes down as the temperature goes up. Corrosion of uranium dioxide in water is controlled by similar electrochemical processes to the galvanic corrosion of a metal surface. Mixed oxide, or MOX fuel, is a blend of plutonium and natural or depleted uranium which behaves to the enriched uranium feed for which most nuclear reactors were designed. MOX fuel is an alternative to low enriched uranium fuel used in the light water reactors which predominate nuclear power generation; some concern has been expressed that used MOX cores will introduce new disposal challenges, though MOX is itself a means to dispose of surplus plutonium by transmutation.

Reprocessing of commercial nuclear fuel to make MOX was done in the Sellafield MOX Plant. As of 2015, MOX fuel is made in France, to a lesser extent in Russia and Japan. China plans to develop fast breeder reactors and reprocessing; the Global Nuclear Energy Partnership, was a U. S. proposal in the George W. Bush Administration to form an international partnership to see spent nuclear fuel reprocessed in a way that renders the plutonium in it usable for nuclear fuel but not for nuclear weapons. Reprocessing of spent commercial-reactor nuclear fuel has not been permitted in the United States due to nonproliferation considerations. All of the other reprocessing nations have long had nuclear weapons from military-focused "research"-reactor fuels except for Japan. With the fuel being changed every three years or so, about half of the Pu-239 is'burned' in the reactor, providing about one third of the total energy, it behaves like U-235 and its fission releases a similar amount of energy. The higher the burn-up, the more plutonium in the spent fuel, but the lower the fraction of fissile plutonium.

About one percent of the used fuel discharged from a reactor is plutonium, some two thirds of this is fissile. Worldwide, some 70 tonnes of plutonium contained in used fuel is removed when refueling reactors each year. Metal fuels have the advantage of a much higher heat conductivity than oxide fuels but cannot survive high temperatures. Metal fuels have a long history of use, stretching from the Clementine reactor in 1946 to many test and research reactors. Metal fuels have the potential for the highest fissile atom density. Metal fuels are alloyed, but some metal fuels have been made with pure uranium metal. Uranium alloys that have been used include uranium aluminium, uranium zirconium, uranium silicon, uranium molybdenum, uranium zirconium hydride. Any of the aforementioned fuels can be made with plutonium and other actinides as part of a closed nuclear fuel cycle. Metal fuels have been used in water reactors and liquid metal fast breeder reactors, such as EBR-II. TRIGA fuel is used in TRIGA reactors.

The TRIGA reactor uses UZrH fuel, which has a prompt negative fuel temperature coefficient of reactivity, meaning that as the temperature of the core increases, the reactivity decreases—so it is unlikely for a meltdown to occur. Most cores that use this fuel are "high leakage" cores where the excess leaked neutrons can be utilized for research. TRIGA fuel was designed to use enriched uranium, however in 1978 the U. S. Department of Energy launched its Reduced Enrichment for Research Test Reactors program, which promoted reactor conversion to low-enriched uranium fuel. A total of 35 TRIGA reactors have been installed at locations across the USA. A further 35 reactors have been installed in other countries. In a fast neutron reactor, the minor actinides produced by neutron capture of uranium and plutonium can be used as fuel. Metal actinide fuel is an alloy of zirconium, uraniu

Neotinea ustulata

Neotinea ustulata is a European terrestrial orchid native to mountains in central and southern Europe, growing at up to 2,400 m elevation. The plant is considered Endangered in Great Britain and Least Concern internationally based on IUCN Red List criteria; the burnt-tip orchid was voted the county flower of Wiltshire in 2002 following a poll by the wild flora conservation charity Plantlife. Neotinea ustulata grows from two spherical tubers with thick roots, it is believed. Plants have 3 to 9 cm leaves with prominent veins, along with a couple of leaves around the flower stem, which can reach 28 cm, though less than 13 cm tall. Flowers are born in a dense cylindrical pattern, with individual plants capable of producing up to 70 flowers; the sepals and petals form a 3 mm hood, reddish-brown, over a white crimson-spotted lower lip, 4 mm. Flowers have a strong fragrance, described as similar to honey, though flowers do not produce nectar. N. ustulata flowers from May with the subspecies, Neotinea ustulata subsp..

Aestivalis blooming in July in England. The late flowering subspecies has a unpleasant aroma, indicating different pollinators; the common name comes from the tips of the flower buds having a burnt appearance. Seed set for flowers is low, at around 20%, but each seed capsule may contain 2000-4000 seeds, which are dust-like and travel hundreds of kilometres on the wind. Neotinea ustulata is distributed throughout central and south Europe, with its main populations in Spain and Greece in the south, reaching England and southern Sweden in the north, reaching as far east as the Caucasus and Ural mountains, it grows as high as 2,400 m elevation in the Alps. It grows on chalky subsoil in grassland; the plant's largest population in northwest Europe is in Wiltshire, England. The early-flowering subspecies Neotinea ustulata var. ustulata is pollinated by a tachinid parasitic fly Tachina magnicornis. The late-flowering subspecies Neotinea ustulata var. aestivalis is pollinated by the longhorn beetle Pseudovadonia livida and also by bees.

Neotinea ustulata is restricted in which species of mycorrhizal fungi it can partner with, relying upon species in the Rhizoctonia group. One study has indicated that partnership with a species of Ceratobasidium occurs; as this species is one of the smallest European orchids, it relies on low intensity grazing to compete with other plants for light. It is however, not spared by grazers. Wild boar sometimes consume them; the genus Neotinea is named after an Italian botanist, Vincenzo Tineo, Director of Palermo botanical garden and the Chancellor of Palermo University. His published works include'Plantarum rariorum Sicilae' and'Catalogus plantarum horti'; the specific epithet ustulata comes from the Latin "ustulus", meaning burnt. Referring to the appearance of the flower spike, as the common name does. Media related to burnt orchid at Wikimedia Commons Data related to burnt orchid at Wikispecies

Tidal Enterprise Scheduler is a job scheduler created by Tidal Software, Inc. It is now owned by the Dillon Kane Group, who purchased it from Cisco Systems and renamed it to Tidal Workload Automation. More this category of software is labeled as "workload automation", an industry term for the next generation of job scheduling applications, it is comparable to BMC Control-M or CA Workload Automation AE. The core functionality of TWA is the ability to schedule batch jobs, it is designed to carry out repetitive tasks as defined in a schedule based upon calendar and event conditions. A calendar can be intricate depending upon design. Tidal works as a distributed system that can be controlled from a centralized location which agents connect to; this allows batch jobs to be unattended in the background across a list of servers. It has helped to define the industry, it is in use by over 400 organizations. Tidal Workload Automation is one of the oldest enterprise batch schedulers still in active production.

It dates back to 1979 when it was created by Tidal Software in Palo Alto, California. In 2009 it was renamed to Cisco Workload Automation. On Nov 16, 2017, Dillon Kane Group completed acquisition of Cisco Workload Automation, renamed to Tidal Workload Automation. Batch jobs are scheduled and run across different operating system platforms and business application environments. Agents are supported on the following platforms: Windows Linux z/OS OpenVMS Beyond running jobs, in the background, on a schedule, a more elaborate set of functionality is provided: Dependencies Users, authentication Master/Agent architecture - distributed environment Clustering with Master/Backup/Faultmon to prevent single point of failure Notable issues may include GUI performance and lag during user interaction. Performance of the interface may degrade when displaying large lists of agents. No studies or benchmarks showing performance data have been published. Performance concerns may be dependent on underlying hardware and architecture implementations.

Tidal is geared towards supporting new technologies including cloud and big data. It is designed for automation, it has been built to work as a component with Cisco's other technologies. List of job scheduler software

The Counterfeit Plan

The Counterfeit Plan is a 1957 British crime film directed by Montgomery Tully and starring Zachary Scott and Peggie Castle. A gang of criminals, led by sociopath Max Brandt, escape from France and set up a counterfeit operation to make British £5 and American $1 notes in the cellar of a large English country house now owned by Louie Bernard. Brandt forces Bernard, who worked for the British Government during WW2 making foreign counterfeit currency, to make the master die plates by holding his daughter, Carole, an artist, as a hostage; when Bernard finds out that Brandt has tried to rape his daughter and has killed his housekeeper, because she witnessed the attempted rape, he anonymously posts one of the forged £5 notes to the police with a letter describing the counterfeit operation. When Brandt is told about this by Duke he confronts Bernard. Meanwhile, the police close in on the gang's headquarters; the film features professional snooker world champion Horace Lindrum in a small role playing himself.

This is used as cover for one of the meetings with other criminals to discuss the sale of the forged British £5 notes to them. Another similar meeting is camouflaged as a boxing match. Zachary Scott as Max Brant Peggie Castle as Carole Bernard Mervyn Johns as Louie Bernard Sydney Tafler as Harry Flint Lee Patterson as Duke Eric Pohlmann as Frank Wandelman Robert Arden as Bob Fenton Chili Bouchier as Gerta John Welsh as Police Inspector Grant Aubrey Dexter as Joe Lepton David Lodge as Sam Watson The film was the first of three between Amalgamated Productions and Anglo-Amalgamated, it was popular in the UK.
