Near Misses are defined in terms of the chances of core meltdown.
Worse accidents are based on ``lost lives" and/or cost associated with the incident, possibly inlcuding the cost to restore working reactor. Worse accidents are based
You could pour thru the NRC records but there are other organizations who do the hard work. ``Greenpeace ss the largest independent direct-action environmental organization in the world." [Example: Correlation between seimic activity and nuclear plants] But independent of whether you want to save the whales, the organization collects solid data and makes it available freely. But it would appreciate your money and active support. That is your decision. Here I use their data. An American Chernobly: Nuclear ``New Misses" at US Reactors Since 1968
Greenpeace has organized nearly 200 US ``near misses" since Chernobyl. First table below is significant near misses. After the date, is the risk assessment in ppt (part per thousand of core meltdown) and final where the NRC was aware of the possible as a result of their inspection process:
|2002 Feb 27||6.0||NO||Davis Besse, OH||Vessel Head Degradation src|
|1991 Aprl 3||6.0||NO||Shearon Harris, NC||High Pressure Injection ???|
|1986 June 13||3.0||NO||Catawba 1, SC||Small Preak Loas of Coolant Accidnet|
|1994 Sep 17||3.0||NO||Wolf Creek, KS||Reactor Coolant System Blow Down|
|1996 Feb 6||3.0||NO||Catawba 2||Loss of Offsite Power (LOOP)|
|1986 Dec 27||2.1||YES||Turkey Point 2, FL||Control Rods Failed to Insert|
|1990 Mar 20||1.0||NO||Vogtle 1, GA||Loss of Offsite Power during shutdown|
|1990 Mar 20||1.0||NO||Vogtle 2, GA||Loss of Offsite Power during shutdown|
Greenpeace identified 42 important near isses-- risk of meldown greater than 100 ppm. Only one (1) was on the NRC radar.
More important are repeat offenders that have mutliple near misses. A likely suggestion is that there are several design flaws that are not being actively monitors -- not even by the NRC.

The nervous person would be concerned that nuclear reactors are as dangerous as they were 20 years ago when Chernobyl scared millions to the ``realigies" of badly designed reactors. But no US reactor is as badly designed as Chernobyl. Indeed a review of world reactors doesn't turn up. However Greenpeace doesn't believe this and strongly warns of an American Chernobyl.
