A 14-month Count of Nuclear Plant Shutdownsgreenspun.com : LUSENET : TimeBomb 2000 (Y2000) : One Thread |
For what it's worth, here is my count of nuclear plant shutdowns since December 1998. As source reference, I used:http://www.nrc.gov/NRR/DAILY/drlist.htm
My criteria for exclusion were:
Refueling Outage;
Storm Outage (hurricane, flood, lightning strike, etc.);
Biological Cause (seaweed, fish, turtle, etc., clogging of intakes);
Shutdowns occuring for or during planned maintenance;
Shutdowns occuring during a startup cycle after an earlier shutdown.
Dec98: 7 shutdowns Jan99: 6 shutdowns
Feb99: 4 shutdowns
Mar99: 6 shutdowns
Apr99: 11 shutdowns
May99: 12 shutdowns
Jun99: 14 shutdowns
Jul99: 7 shutdowns
Aug99: 9 shutdowns
Sep99: 10 shutdowns
Oct99: 4 shutdowns
Nov99: 6 shutdowns
Dec99: 8 shutdowns
Jan00: 16 shutdowns
Note: The plants counted here do not mean that they were shut down permanently; rather, they were shut down suddenly (and usually for only a few days or weeks) because of a variety of unexpected technical "gliches". These data are presented for month-to-month comparison only.
Enjoy!

Sorry for the lousy formatting. Anyone want to try their hand at graphing this, just for fun?Spindoc'

I wonder who has the data at their fingertips that might correlate high shutdown rates (April, May, June, September) with Y2K upgrade deadlines set by the NRC. If I remember correctly, June 30 was a final upgrade deadline for nuke facilities: June, here shown with 14 shutdowns.These figures for January 2000 don't seem to establish much -- unless some of the highs for the preceding months can be ignored as reprsenting these upgrade shutdowns. In that case, the January figures are 2-4 X the average -- that would be significant. Recall that John Krempasky said that if there were more than 9 shutdown in January he would absnet the Board and never repost, etc. S**t, this is not a lot to go on, and nuclear things seem to have grown much quieter over the last two weeks .....

Squirrel Hunter,You might want to check out the large number of "refueling" outages occuring during October 1999, in comparison with other months.

So what's your point? Went through a bunch of these Event Reports and didn't see the first one blamed upon an "unexpected technical glich". I'm sure you put in quite a bit of work compiling this info but perhaps you should provide a detailed listing (at least for Jan 2000) so that the true cause is examined before people start drawing the wrong conclusion (which they probably already have).Nukieman

Refueling outages are usually done in Mar/Apr or Sept/Oct because those are the times of least demand on the utility--not the hottest or the coldest months. That's why you'd find so many then--it's simply a matter of load and economics. There's usually an 18-month gap between RFO's, so if you shut down in Mar. of one year, it'll be Oct. of the next until you do it again, and so on.

Yea, there was a lot of 'refueling' goin' on in January, 2000.
