NRC/PG&E MEETING Humboldt Bay Power Plant Special Nuclear Materia I Control & Accountability Project January 19, 2005 1
AGENDAlo d Scope of Special Nuclear Material (SNM) Project
- Status of SNM Project d Completion of A-49 objective d SNM Project final report d Future communications 2
SCOPE OF SNM PROJECT
- Obtain full accountability and control of all SNM at HBPP 0 Accurate 742 inventory report, including fuel fragments I Procedures and controls to ensure inventory accuracy and positive control maintained in the future
- Address unaccounted for A-49 fuel segments U Locate A-49 segments or identify, analyze, and assess likelihood of possible locations of A-49 segments (scenarios) o Public and worker health and safety significance evaluated for possible scenarios o History of processes and controls over SNM at HBPP - cause analysis of SNM accountability issues and A-49 discrepancy 3
STATUS OF SNM PROJECT
- Completed work:
- Procedures revised/developed for handling and accounting of fuel fragments
- Technical Specifications amended to incorporate fuel fragments in licensing basis 0 Tabulated and characterized all found fuel fragments for SNM accounting o 742 Report expanded to include fuel fragments o Stored all found fuel fragments for positive SNM control o Updated spent fuel pool (SFP) map to identify physical locations of all found SNM 4
STATUS OF SNM PROJECT (cont.)
- Work to be completed in January 2005 o SFP search for fuel fragments and A-49 segments o Onsite non-SFP search for A-49 segments o Tabulation of fuel fragments for SNM accounting
- Storage of fuel fragments for SNM control
> Analysis of possibility that A-49 segments have been found o Current SNM control and accountability finalized o Theft or diversion of A-49 rod segments evaluated
- Completion of SNM full accountability & control objective o Update of SFP map to identify SNM physical locations o Perform physical inventory o Issue 742 Report including fuel fragment accounting information 5
COMPLETION OF A-49 OBJECTIVE mJanuary through April activities o Complete documentation search o Complete interviews o Development and resolution -of scenarios
- SNM Project final report by May 15
. LER revision by June 15 o Includes final SNM Project report information 6
SNM PROJECT FINAL REPORT m Scenarios/possible locations for the three A-49 rod segments m Level of detail for scenarios
- Discrepancies, inconsistencies and missing information in the historical control and accountability of SNM 7
Scenarios/Possible Locations for the Three A-49 Rod Segments o In the SFP o Onsite storage outside SFP o Licensed Low Level Radioactive Waste storage facilities
- Hanford
- Barnwell
- Beatty o Other direct shipments
- Nuclear Fuel Services
- GE Vallecitos
- Battelle Laboratories o Theft or Diversion 8
Level of Detail for Scenarios
- Screens o Plausible/Not Plausible Determination
> Low Level Radioactive Waste shipments from outside SFP
> Low Level Radioactive Waste shipments from SFP
- Time frame
- Physical size
- Properties
- Plausible scenario probabilities o Highly improbable
- Possible but unlikely o Reasonably possible
- Public and worker health and safety significance evaluated for possible but unlikely and reasonably possible scenarios 9
Discrepancies, Inconsistencies and Missing Information in the Historical Control and Accountability of SNM
- Comprehensive records review and interviews
- Additional record discrepancies, if any, identified and resolved o Additional information on SNM accountability identified
- Discussion of history of control and accountability of SNM at HBPP o Review of processes, procedures and controls employed at HBPP o Discrepancies discovered o Missing information identified o Cause analysis for A-49 rod segments o Corrective actions 10
I.
FUTURE COMMUNICATIONS
- Meet with Community Advisory Board to provide project updates and future actions U Status updates to and discussions with stakeholders
- Issue press release associated with completion of SFP search
- Continue bi-weekly conference calls until SNM Project final report issued m Continue weekly status reports until SNM Project final report issued m Meet with NRC as necessary m Public meeting(s) in Eureka as NRC desires 11
