Good discussion Gentlemen,
1 - Welding or soldering a pipe with water inside of it can be done, it only requires a greater heat source than that the little propane tank and soldering torch you purchase at your hardware store - but it just does not produce the ideal joint.
2 - For U235, the...
Errata
Gentleman,
My decay heat values given above are incorrect.
The decay heat value initially after shut down is about 7% and after a week 0.2%.
So the initial heat generated is 238MWt.

My apologies.
Gentleman,
A couple items to be added to the definition of "melt down" that are paramount in reactor safety are:
1 - When zirconium melts is gives off hydrogen gas - hence the explosion.
2 - If enough uranium pellets fall to the bottom of the reactor there is the potential for self...
Sujins,
1) Yes, The volumetric flow rate through a pipe is constant.
When a restriction (orific)is placed within the pipe, it impedes that mass flow, to maintain the volumetric flow constant the velocity of the fluid across the restriction increases.
This increase in fluid velocity produces a...
Though its not required by NEC, here's what we use in the US:
480V System - brown, orange, yellow, with grey for the neutral
240V System - black, red, blue, with white for the neutral.
DC System - Blue.
Systems powered form an outside source (interlocks) - yellow.
Any elementary text on Nuclear Engineering would provide you with point source equations. As is stated above radiation follows the inverse square law, similar to light and gravity propagation.
You will need the initial source concentration to calculate the intensity.
Teck90 is an pvc jacked interlocked armored cable (IAC) and the armor can be either steel of aluminum. Also, the conductors are enclosed in a overall pvc jacket within the IAC jacket. It is essentially a tray cable inside IAC jacket. Its construcrtion, durability, and cost make it an excelent...
