The TracWorks® data management system provides nuclear
plant operators, engineers, and administrators with a comprehensive, current,
single source of fuel- and component-related information.
Background
In most cases, utilities manage the various
fuel assembly data sets (Special Nuclear Materials data, inventory information
or refueling campaign information) as separate entities and integrate the
various pieces by hand. The same information required by different organizations
can have different sources, histories, and pedigrees, which may lead to
inconsistencies and the potential for errors. TracWorks provides life-cycle
tracking, data management, and reporting for all fuel assemblies and components.
Benefits
- The TracWorks system provides an exceptional level of protection against
costly, time-consuming errors in assembly selection and placement. It also can
help to reduce the time needed to perform both routine and specialized plant
operating, maintenance, and administrative activities.
- It can significantly reduce the probability of fuel selection errors such as
selecting the wrong assembly or attempting to place a spent assembly in an
occupied storage location during refueling, eliminating the time required to
resolve errors and reducing the possibility of NRC involvement.
- The effort spent in generating and checking the fuel shuffle can be reduced
by several man-weeks (versus preparing the shuffle by hand) and the shuffle
itself can be optimized to potentially minimize critical path refueling time.
- TracWorks virtually eliminates the effort required to generate SNM reports
for the NRC.
- The administrative controls required, even for very complex burnup credit
racks, can be automated to reduce the required effort and improve reliability,
as well as to provide support for whatever controls might be required to account
for absorber degradation.
- The availability of the fuel rod and fuel assembly manufacturing data can
significantly reduce the time required on-site for an audit of the manufacturing
plant.
- TracWorks provides a single, universally available, controlled access source
of the various fuel assembly data.
Description
TracWorks software streamlines tracking,
data management, and regulatory reporting for the entire life cycle of fuel
assemblies and core components. It collects, maintains, and provides information
about assembly and component locations and movements during the refueling
process and operation, assembly burnup, and isotopic inventory (both in-core and
out-of-core), fuel rod burnup and isotopics for fuel that has been removed from
its original assembly, fuel assembly and component inspection results, and
manufacturing data.
TracWorks has three baseline modules and three additional
modules:
- Inventory management for assembly and core components from delivery to final
disposal
- Fuel properties tracking for up-to-date information about individual fuel
assemblies, including isotopic histories and burnup histories
- Reporting for regulatory requirements
Additional Modules
- Fuel movement planning
- Move sequence tracking
- Manufacturing data integration
Available services include continuing hardware procurement
services, the support of the initial historical data load, base or full
Engineering System Control Module (ESCM) installation, upgrades, and
maintenance.
TracWorks can be integrated with the Westinghouse APA core
design system and the BEACONâ„?core monitoring system. It uses the APA-developed
final core loading plan information to make sure that the reload move sequence
provides the proper in-core fuel and component arrangement. BEACONâ„?provides
TracWorks with burnup and isotopic information during core operation for current
inventory and depletion information, move sequence generation, burnup credit
compliance monitoring, and SNM reporting.
