Reduce outage scope and complexity through single-train outages, made possible with extended Surveillance Test Intervals balanced with more on-line maintenance using Extended Completion Times.
Reduce maintenance, operations resources, and accumulated radiological dose by extending the intervals between many Technical Specification-required Surveillance Tests.
Minimize regulatory interactions through Risk-Informed Extended Technical Specification Completion Times.
Re-categorization of system risk-importances potentially minimizing component replacement costs.
Demonstrable evidence of a Risk-informed culture though the reliable and “fast” real-time risk monitor used by the Work Management and Control Room Operators to identify and manage plant risk.
over
24 hours
of savings in Outage Critical Path Time by performing single train of Integrated ESF/LOOP Test Sequence per outage. Similar savings through on-line EDG maintenance to address outage DID.
Annual Savings of OVER
24
hours
outage time
outage time
Plus 4 Engineering Man Months just for selected battery parameter testing; much more available through other surveillance test extensions
OVER
$1 million
savings per shutdown per day.
One plant avoided 6 shutdown challenges without Enforcement Discretion and without one-time Technical Specifications changes over 3 year period.
up to
$400K
savings per unit per year
by eliminating labor and materials for maintenance, tests, & inspections.
over
$600K
of costs avoided at one U.S. site.
Processes to clearly identify, assess and manage risk were used to address an emergent issue during planned maintenance, reducing a potential cited violation to an observation by the regulator.
