Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

It is necessary to apply cyber security functions to control system in nuclear power plant complying with Regulatory Guide 5.71. According to the regulations, B.4.9 Cryptographic Module Authentication of Appendix B, technical security controls, Critical Data Asset ( CDA ) s authenticate cryptographic modules has to accord with FIPS 140 2. The specification explains the cyber security functional requirements are e valuated at the Common Criteria ( CC evaluation assurance. Thus, the security function algorithms for encryption and decryption developed in Nuclear Instrumentation and Control ( I&C control system have to consider a cryptographic module validation program ( which is validation scheme in Common Criteria Standard. As regulatory guide 5.71, many cyber security technical functions have to be developed and applied to CDAs. The functions are most going to utilize the encryption and decryption functions. The refore it must be important for satisfying the functions to validation process on the developed encryption and decryption algorithms. There has been no experience to apply and evaluate the cyber security functions to control systems in nuclear power plant I&C. The standards for each cryptographic algorithms p rovide the test vector s and process of validation. In case of Korea CMVP standards and National Institute of Standards and Technology (NIST) CMVP , they include validation objects, target modules, valida tion baselines, process schemes, process terms, validation test cases. This paper proposes modeling schemes to perform the procedure of validating test vectors among CMVP procedures for thecryptographic algorithms to be developed in the nuclear control system such as Programmable Logic Control (PLC) and Distributed Control System (DCS). By utilizing the proposed methodologies, it is possible to further validate the stability of the algorithm implementation function as well as the test vectors of the necessary procedures with standard test methodologies and standard documents which must be satisfied.
