U.S. NRC Regulatory Support

ChesNuc has supported the US NRC in developing Regulatory Guides and supporting licensing reviews for new nuclear plants.

FSAR Chapter 11 (Radioactive Waste Management) review and dose calculations
FSAR Chapter 12 (Radiation Protection) review and calculations
Regulatory Guides supporting implementation of 10 CFR 20 (Radiation Protection Standards)

We have also assisted NRC for its Environmental Assessments for In Situ Uranium Recovery.

Radiation Protection Programs and Assessments

Our staff has CHP and NRRPT certifications as well as ANSI qualified Radiation Protection Managers and INPO/WANO qualified assessors. Our experiences in operational health physics/radiation protection program management allow us to provide practical and efficient solutions in solving operational issues.

RP Program Assessments and Bases - ALARA, internal dosimetry and bioassay programs, external dosimetry, air sampling, respiratory protection.
Assessment Capabilities - Radiation transprot (MCNP) and shielding analysis (Microshield, QAD, Skyshine), VARSKIN for shallow dose assessment
Emergency Response - Offsite dose assessment methods, Emergency Action Level decision trees, drill scenario support
Radioactive Waste Management- Processing Assessments, 10 CFR 61 Waste Classification, 10 CFR 20.2002 Alternative Disposal
