Wes, et al:

Thanks for posting these pics.  I loved the pic of the wall of gauges.  

Although not a rector HP, during the course of my career I have been to many plants of different kinds in various countries, PWR, BWR, HTGR, graphite core, swimming pool, small research...  I believe these are graphite block reactors, technology same as Chernobyl as Peter said.  I was in a similar nuke plant in Lithuania in about 1990.  It was not quite so clean looking as this, I think due to ugly foam that looked like after the fact fire added protection or insulation.  I didn't see the reactor core area.    Not everyone going into the reactor I went into was given individual monitoring, but the Russian scientists working there had TLDs.  

The reason the pond has great fishing is probably because it is not reserve water but they are releasing their secondary side coolant water in the pond.  I had heard from the workers at the plant that I visited that the secondary side water was used to heat the town - indeed I found it quite warm temperature wise in the hotel!

Would love to see more people's input about pics.

"fairly new"....   this is a typical RBMK-1000, of which they have 2 of
eneration 2 (=Chernobyl 3+4)(pic. 1) and one of generation 3 in Smolensk.
ll definitively obsolete technology.
he pictures seem to be taken in unit 1 or 2, according to the design,
hich I know from Chernobyl. On picture 28, panel 1T, you can see the
in)famous AZ5 button (the red one under the protective cover)(I think at
n pic. 40 you can see the flow scheme of the primary loop quite well.
ote the four drum steam separators; the red lines (labelled "par na TG")
ead to the turbines. Lower left and right you see the feedwater pumps, of
hich the engine heads are shown in pics. 16 and 17.
 find pic. 39 particularly interesting, this seems to be a relatively new
eature (I haven't seen it so far). The curve on the left side seems to be
he axial power distribution, while the big graph (a layout of the reactor
ore) seems to display enrichment. 
ote also the fuel changing machine, pics. 19 and 23, which allows
efuelling during operation.

I came across this web site with dozens of pictures of a fairly new
nuclear power reactor. The author is clearly not highly skilled in nuclear
technology, but has taken some spectacular inside pictures.


Can the power reactor types on Radsafe compare and contrast this site with
US and other power reactors? I was impressed with how clean it seems.
