t-DEFINING PRINCIPLES 1
There is a level of licensee safety performance that could warrant decreased NRC interaction It should not be expected that any process could provide a " leading" indication to every plant event caused by the failure of an SSC or human error The process should establish risk-informed thresholds that would trigger early interventions to arrest declining performance prior to it l
becoming unacceptable i
Performance indicators (PIs) (supplemented with some inspection) will i
form the rebuttable presumption for licensee assessment t
Pls and their thresholds should be risk-informed (maximize) i
{
To account for the varying quality of licensees' PRAs, Pls should be selected generically to the maximum extent possible. Site-specific thresholds for these Pls would be set if necessary.
The goal is to develop responsive, concurrent Pls ATTACHMENT 3 i
l
I DEFINING PRINCIPLES (continued) i Risk-significant inspection findings and other information sources will be j
used, when appropriate, to develop a compelling case to cverturn the indicator results j
A risk-informed baseline inspection program should cover those j
risk-significant attributes of licensee performance not adequately j
covered by Pls The inspection program will also verify the adequacy of the Pls and j
provide for event response l
Enforcement actions taken (e.g., number of cited violations, amount of l
civil penalties) should not be an input into the assessment process 4
i I
1 -
POLICY ISSUES Integration of Pls and inspection results t
No clear consensus on how (but, consensus that Pls and inspection results should not be artificially merged / integrated)
Current PPR and'SMM processes could perform this function, but i
objectivity and scrutability would continue to present a challenge i
i Treatment of licensee self-assessment results.
Voluntary reporting program is preferable to rulemaking Implementation issues (mechanism, frequency)
Policy issues l
l l
i
L NEXT STEPS t
3 Teams Framework team (responsibilities include: performance indicators, I
inspection bases, thresholds)
Inspection team (responsibilities include: scope, depth, frequency,.
resources) l Assessment team (responsibilities include: integration methodology, action, communication, follow-up, resolution)
I Team Leaders j
Framework team: Pat Baranowsky, AEOD Inspection team: Bruce Mallett, Region ll l
Assessment team: PIPB, NRR l
Staffing i
Framework and inspection teams assemble at headquarters and begin work on October 19,1998 Assessment team is scheduled to begin work in early November ATTACHMENT 4 4
