Talk:Loss-of-coolant accident

As a student in Nuclear Engineering I have been following and making modifications to this wiki for months. It has been a very educational experience, and has woken me up to the power of this media. Very useful if you know how to use the information, and as long as good references are made!

It's a myth that a mixture of graphite and air caught fire at the Chernobyl accident. Graphite as used in nuclear reactors are highly resistant to oxidation (fire) even at extremely high temperatures (well above accident temperatures). The characteristic red glow from the core seen on aerial pictures are the graphite glowing caused by the high temperature of the core material, not graphite burning.

ECCS systems
I can't speak for PWRs, but for BWRs the ECCS systems typically consist of two independent trains of LPCS or LPCI (low pressure core spray or -injection) and two independent trains of HPCS or HPCI (high pressure core spray or -injection). The ABWR has three ECCS systems. Simesa 02:31, 14 April 2007 (UTC)
 * Just semantics I guess - in CANDU all of these components are collectively called the ECCS. Whitlock 03:45, 14 April 2007 (UTC)

Normal Loss
I am wondering if anyone knows if there is a normal loss of water through sublimation, etc that occurs in a closed loop? Do nuclear reactors need water added to either of the closed loops? — Preceding unsigned comment added by Philfromwaterbury (talk • contribs) 14:08, 29 August 2014 (UTC)
