Question about Midland Cogenerating Nuclear Power Plant

  • #1
Midland Nuclear Power Plant was going to have two nuclear reactors from Babcock & Wilcox. Unit 1 was to have a capacity of 460 MWe, while Unit 2 was to have a capacity of 808 MWe. Were the reactors twins that simply had different steam machinery due to the cogeneration requirements or were they two unrelated designs? Were both reactors to be used for cogeneration (perhaps with Unit 2 as a backup unit) or was Unit 2 intended only for electricity generation?

It appears that both units had the same thermal power rating (2468 MWt) but Unit 1 was rated at 492 MWe (net) and Unit 2 was rated at 818 MWe. I believe the units had cores with 177 assemblies of 15x15, which was standard for B&W at the time. The reactors were similar to the units at Oconee, TMI, Davis Besse, Crystal River, ANO-1 and Rancho Seco.

Some repercussions

It seems that the responsible parties failed to stabilize the ground before they started construction the containment building and other major structures. Of course, the redesign and retrofitting in the wake of TMI's accident caused a substantial increase in cost.
