Passive cooling, turbine-driven cooling[edit]

The "Essential Service Water System" - that's the normal water circulation if I understand it correctly? It seems that all cooling systems mentioned in the article requires electrical power to operate? I've heard that newer power plants are supposed to have three layers of emergency cooling in case the active cooling should be lost; passive cooling (which would keep the core below melting temperatures for at least 24 hours without any power or work done, and infinitively if the water is replenished), turbine-driven cooling (cooling circuits kept going by the reactor heat itself, self-sustaining for as long as the reactor needs to be cooled down) and air-cooling ... — Preceding unsigned comment added by Tobixen (talk • contribs) 20:33, 29 March 2011 (UTC)[reply]

Suffering metal? As a core catcher[edit]

The current version calls a metal body beneath the core, designed to melt with corium and dilute it, increasing the heat dissipation, a "suffering metal"... Nothing but really horrible music videos result from a Google search for this term. So, changing it to "target" and assuming this is the result of a translation difficulty.

safety system failure probability[edit]

it would be worth putting together a section on failure probabilities for these systems.

Scramming PWRs vs. BWRs[edit]

"PWRs can also scram the reactor completly with the help of their control rods" This sentence ist not correct. PWRs have according to their design base less control rods than have the BWRs. They shut down the reactor by using auxilliarly their normal boration system too. Please correct this. Thanks--2A02:1206:4596:4A10:F829:2C30:7992:9902 (talk) 15:27, 7 January 2018 (UTC)[reply]
