Probability of an explosion

The most significant hazard of this process is the probability of an explosion if the concentration of ammonia in the reactor is inadvertently allowed to reach the explosive range, > 14 per cent. 

Venting Venting is the process that is used to deal with liquids or liquefied compressed gases where a danger, such as an explosion or mechanical rupture of the container or vessel, is considered likely. The method of venting will depend on the nature of the hazardous material. In general, it involves the controlled release of material to reduce and contain the pressure and diminish the probability of an explosion. 

Weathered LNG on water. Erratic results were reported. The highest probability of an explosion resulted when the most weathered LNG was used. 

The probability of an explosion was 100% if the sodium carbonate were mixed with more than 7 wt. % NaCl or 10 wt. % NaOH. 

Explosions with green liquor were more violent than those with water, and, for both, an increase in temperature reduced the severity and probability of an explosion. 

Higher aluminum temperatures usually increased the probability of an explosion. This was especially true if the depth of water in the water tank were also increased. 

No explosions resulted if the water depth exceeded about 70 cm (but this depth could vary with the size of spill studied). For intermediate depths, the probability of an explosion was related both to the depth and to the initial aluminum temperature. For deeper pools, a higher temperature was necessary. 

Generally, soluble oils prevented explosions except in very cold water. Some wetting ents increased the probability while others decreased the probability of an explosion. 

The size of the square water vessel was varied from 16.5 cm to 61 cm on a side with little variation in the probability of an explosion. A few tests carried out in vessels 122 cm on a side led to explosions which appeared to be milder. (The effect of water depth was noted earlier.)... 

The E l module did not have gas detection which, if located in the air intake, would have significantly reduced the probability of an explosion. Gas detectors should be fitted in the HVAC supply to all nonhaz-ardous areas where ingress of released hydrocarbon gas is credible. There was no automatic production shutdown from fire or gas (F G) detection in production modules. 

Does the average distance a neutron travels through fissionable material before escaping increase or decrease when two pieces of fissionable material are assembled into one piece Does this assembly increase or decrease the probability of an explosion ... 

Sensitiveness A measure of the relative probability of an explosive being ignited or initiated by a prescribed stimulus. 

The fireball is considered to be the gravest outcome. Therefore flash fires are not treated. The conditional probability of an explosion is 0.6 and that of a fireball 0.4. 

An alternative method is to compute the theoretical probability of an explosion event within the radius rp in each scenario the wind direction will move the explosive gas mixture to the plant. The advantage over the lee is that each scenario gives a contribution to the...

In addition to the probability of an explosion, two other factors must be conridered in order to estimate the threat of radionuclide release or diemical hazard rdease (chemical hazard release is dealt vnth in Section 8.2). They are ... 

Radiolysis hydrogen in the air space of the reactor may be accumulated in the event of failure of the gas system. The probability of an explosion in this situation is rather low because of the increased vapour content of the air however, the reactor cover has been provided with rupture devices to release the medium from beneath the reactor cover to the reactor hall. 

Reducing the probability of an explosives mishap from occurring...
