CRITICAL DISCHARGE [6 records]

Record 1 2009-10-07

English

Subject field(s)
  • Nuclear Fission Reactors
OBS

These early plutonium reactors were crude affairs with the main objective being to get the weapons material as quickly as possible. Each "pile" was a honeycomb of carved graphite blocks. Hundreds of horizontal channels ran from the front(charge face) of the reactor to the rear discharge face. Some 35, 000 aluminium cans of uranium were pushed into these channels to assemble the critical mass for the chain reactions to burn away.

CONT

Description sommaire de la pile plutonigène n° 1 de Windscale [.] La conception des piles plutonigènes était très rustique; elles avaient pour objet essentiel de produire du plutonium de qualité militaire par irradiation, dans un empilement octogonal, de 15,2 m de diamètre et de 7,6 m de longueur, constitué de blocs de graphite, de boîtiers d'aluminium.

CONT

Critical lip pressure method... If hot water or a water/steam mixture is discharged at sonic velocity through an open-ended pipe, and if the pressure is measured at the discharge lip of the pipe, this pressure is a measure of the heat flow of the discharged fluid.

PHR

Critical lip pressure.

CONT

Méthode de la pression critique de bordure. Si de l'eau chaude ou un mélange eau/vapeur est dégagé à la vitesse du son à travers un tuyau à extrémité dépourvue de filetage, et si la pression est mesurée à la bordure du dégagement du tuyau, cette pression est une mesure du flux de chaleur du fluide dégagé.

PHR

Pression critique de bordure.

PHR

Mesurer une pression de bordure.

Subject field(s)
  • Water Treatment (Water Supply)
  • Environmental Management
CONT

The Importance of Clean Water Treatment. The importance of clean water should not be under-estimated. On a local level, reports from the Environmental Protection Agency(EPA) list 5, 000 to 10, 000 of 55, 000 communities in the U. S. that are currently in violation of the Safe Drinking Water Act at any given time.... The Association of Metropolitan Water Agencies estimates that $2 trillion is needed over the next 20 years for repair, rehabilitation, operation, and maintenance of the U. S. water and wastewater treatment infrastructure. The importance of effective water treatment is also critical from an economic standpoint as health concerns and impure water can ruin a product and discharge violations can lead to major fines.

Séminaire de sensibilisation/formation au traitement des eaux propres et des eaux usées industrielles en Afrique, Paris, France, du 22 novembre au 9 décembre 1994. [...] Le projet vise à améliorer les compétences et qualifications des responsables (ingénieurs et techniciens supérieurs) d'unités de traitement d'eaux propres et d'eaux usées industrielles en vue d'assurer une meilleure protection de l'environnement, des économies d'eau et une amélioration des [procédés]industriels. Le projet s'inscrit également dans le cadre des recommandations du programme agenda 21 adopté lors de la conférence des Nations Unies pour l'environnement et le développement qui s'est deroulée à Rio de Janeiro en Juin 1992 et qui insistent sur l'utilisation des technologies appropriées pour la prévention de la pollution.

Subject field(s)
  • Corporate Security
  • Electrical Engineering
  • Security
CONT

Critical standby power battery backed installations need to perform instantly when called upon during an outage. To ensure maximum reliability from the considerable investment made a number of rules should be observed. Once installation has been completed, the battery must be commission charged and a full autonomy discharge/recharge cycle test undertaken to establish the ’as new’ performance.

CONT

Critical lip pressure method... If hot water or a water/steam mixture is discharged at sonic velocity through an open-ended pipe, and if the pressure is measured at the discharge lip of the pipe, this pressure is a measure of the heat flow of the discharged fluid. James has deduced... [a] formula expressed in f. p. s. units... Where the two phases of a water/steam mixture are segregated by means of a cyclone separator the water can be measured either by a cooled orifice or, after allowing for the flashed steam, by means of a V-notch or weir. Alternatively, however, the water may simply be discharged at sonic velocity through an open-ended pipe and measured by applying... [James] formula. By measuring the temperature of the water leaving the separator its enthalpy is made known, and... [the flow] can be deduced from... [the critical lip pressure].
