xenon | Definition, Properties, Atomic Mass, Compounds .

Xenon, chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colorless, odorless, and tasteless.

The Chernobyl Disaster

The Chernobyl Disaster

Because Xenon built up due to a rapid shut-down mainly caused by nearby coal plant problem, operators at Chernobyl retracted the control rods all the way out of the core only to notice power instabilities due to the inherent positive coolant void coefficient of the RBMK reactor and reinsert them.

"Xenon Poisoning" or Neutron Absorption in Reactors

Xenon Poisoning. A major contribution to the sequence of events leading to the Chernobyl nuclear disaster was the failure to anticipate the effect of "xenon poisoning" on the rate of the nuclear fission reaction in the Chernobyl nuclear reactor.. Neutron absorption is the main activity which controls the rate of nuclear fission in a reactor - the 235 U absorbs thermal neutrons in order to .

Xenon 135 - Nuclear Power

Xenon 135 - Nuclear Power

Production and Removal of Xenon 135. In general, there are two ways of xenon 135 production in the reactor:. Decay of 135 I.Most of xenon 135 is produced by beta decay of 135 I (γ I,total = 6.4%). In fact, the 135 I is a direct fission product (γ I = 3.1%) and a decay product of tellurium 135 (γ Te = 3.3%), but the half-life of tellurium 135 is so short (~ 19 sec), that iodine-135 can be .

Xenon Transients - Response to Reactor Power Changes

Xenon Transients - Response to Reactor Power Changes

The most spectacular and well known phenomenon associated with xenon 135 is the behaviour of a reactor after a reactor shutdown. Recall, the proportion of 135 I (6.6h) and 135 Xe (9.2) half-lives is very important and determines these transients, especially those with power reduction, where the xenon buildup rate is higher than xenon decay.

Xenon poisoning in naval nuclear reactors? | Yahoo Answers

Xenon poisoning in naval nuclear reactors? | Yahoo Answers

Nov 06, 2006 · Xe-135, a secondary fission product, has a voracious appeitite for neutrons, and a civilian power reactor, once shut down, cannot be restarted until the xenon is sufficiently decayed. Such a delay would be unpleasant for any ship, and unacceptable for a warship. What methods are used to increase reactivity in naval nuclear propulsion to avoid this problem?

Interesting Xenon Facts and Uses in Chemistry

Xenon-135 is used to absorb neutrons in nuclear reactors. In addition to headlamps and ion drive engines, xenon is used for photographic flash lamps, bactericidal lamps (because it produces ultraviolet light), various lasers, moderate nuclear reactions, and motion picture projectors. Xenon can also be used as a general anesthetic gas.
