Corporation Project Experience

Principal Consultant, 1992 – present
Tetra Tech Advent, Ann Arbor, MI

Provides extensive support to the nuclear power utility industry in several diverse areas.

Fire Protection/Appendix R
Assisted in Fire Protection and 10CFR50 Appendix R analyses for three utility companies.  Prepared design calculations supporting safe shutdown strategies, as well as associated current licensing basis documents.  Carried out manual action feasibility studies in support of post-fire safe shutdown analyses.  Conducted fire code compliance reviews in support of audit and self-assessment activities, and prepared Fire Protection Engineering Evaluations (GL 86-10 evaluations).  Prepared for and provided direct support to licensees during NRC Triennial Inspections.  Served as lead design engineer for fire protection and as the Fire Protection member of the Integrated Safety Analysis team at a gas centrifuge uranium enrichment facility.  Current member of the Nuclear Energy Institute (NEI) Multiple Spurious Operation Task Force.

Design Basis Reconstitution
Principal author of four Design Basis Documents (DBDs), each prepared for a different utility company, and lead validator (independent system design assessor) for five DBDs.  Involved in various technical capacities with two additional DBDs, and was a major contributor to design basis open item resolution tasks for two utility companies.  Prepared change documentation for Updated Final Safety Analysis Reports (UFSARs).  

Thermal-hydraulic Analysis
Developed spreadsheet models that predict nuclear steam supply system (NSSS) response under various postulated conditions.  Developed other spreadsheet models that predict room temperature response to a variety of postulated scenarios.  Performed room heatup analysis and equipment operability analysis to spatially link the consequences of room cooling failures on core damage mitigation systems for a Level-1 plant PRA.  Documented the PRA performance analysis in PRA system notebooks and cataloged supporting references in companion PRA reference packages.  Assisted in defining new strategy for room heatup related support system states and for binning offsite power recovery consistent with new decay heat removal timelines and associated equipment operability.  Prepared and/or checked revisions to fluid system design basis calculations.

Training
Developed and provided formal training and examinations involving the use of Fire Dynamics Tools in support of GL 86-10 evaluations.  Developed and provided training on maintenance practices and the Maintenance Rule (10 CFR 50.65).  Developed and provided training on the history and development of fire protection regulations for nuclear power plants.

QA
Served as an auditor during several Quality Assurance audits.  Evaluated the suitability of Secondary Record Storage Locations.
