Sharing of Good Industry Practices in Criticality Safety–Panel

Fundamental to the successful operation of any nuclear site is a first class safety culture which strives to continually improve in response to operating experience feedback and good industry practices. Speakers will provide an example of a specific good practice at their site, following which an audience discussion will be initiated on alternative good practices in these areas.

Panelists:

Deborah Hill (NNL)
Catherine Percher (LLNL)
