NOTE: Smoking while doing this would be a bad idea

Accident Analysis and Mitigation: The Safety Analysis Report (SAR) for the NWCF identifies two unlikely, but credible accidents that could result in fatalities to site workers. These accidents are associated with explosions of kerosene in either the calciner cell that houses the equipment or the calciner vessel in which the HLW solution is calcined to ceramic particles. An explosion in the calciner cell is possible if the kerosene spray is not ignited when introduced into the vessel and allowed to accumulate. If ignited, the accumulated kerosene could cause a large and potentially fatal explosion. The primary means of preventing this accident is a temperature interlock. Kerosene flow cannot be initiated prior to the vessel temperature reaching 340\ufffdC, which is approximately 10 percent above the auto-ignition temperature of kerosene.

A similar event, involving a small kerosene fire, occurred at the NWCF in December 1992 when kerosene leaked from a spray nozzle on the calciner vessel and ignited inside the calciner cell. The cause of that incident was a faulty nozzle and improper installation. The contractor corrected these problems by making upgrades to the equipment and revising maintenance procedures.

Cigarettes are a lot hotter than 340 C.

It's not a good idea even if 99/100 times nothing bad will happen...

Cheers,
Scott.

You know, like a fuel injector. === Purveyor of Doc Hope's [link\|http://DocHope.com\|fresh-baked dog biscuits and pet treats]. [link\|http://DocHope.com\|http://DocHope.com]
