This is a good discussion of systems d...Gentleman,<br /><br />This is a good discussion of systems dynamics; however, I suggest that there is one ambiguity that I'm not sure how you would clear up.<br /><br />Why "safety culture" effectiveness rather than "protection" or better yet "performance" (as the systems integral of "production" & "protection")?<br /><br />While there are lots of models of accident dynamics, I've yet to see one where "safety" is modeled as an outcome (I may be being a bit glib here saying never). <br /><br />Unlike protection I doubt that "safety" is a scalar variable even by analogy - for me its a go/no-go emotional state. As you point out snapshots of safety climate appear to be doable, but these rarely offer risk insights of momentum (functional direction and rate of decay). <br /><br />Risk insights about mission performance momentum are what risk managers need and if they don't develop them internally as a matter of course they generally prove resistant to being told about them by consultants or oversight bodies.<br /><br />As a case study, look at the Entergy Confirmatory Order that came out of some radcon problems at Fitzpatrick. Did the Entergy or NRC analysts of this handful of events correctly identify the ailing function (i.e. radcon); does the reported rate of functional failure appear to correspond to the scale of Entergy response?<br /><br />I would contend that NRC was looking for a developmental Safety Culture tightening-up guinea pig, and Entergy volunteered - on behalf of the entire US NP operations sector. This may prove a "useful" experiment for NRC; but were I a VPN at Excelon I'd not be too confident that Entergy has the "right stuff" leadership-wise to be recommending proposed changes to NEI-09-07. <br /><br />What became of INPO, it thought industry-wide performance improvement was their turf?Bill Mullinsnoreply@blogger.com
