Barbara has been with NWT since June 1992. She currently manages the production, verification and distribution of chemistry samples manufactured by the NWT Laboratory. She has authored Q-Chem procedures detailing each step in the manufacturing process, with emphasis on quality assurance and traceability. In addition to her sample production responsibilities, Barbara is a fully qualified analyst providing technical support for most aspects of laboratory operations. Her duties include preparation and/or review of technical reports issued by the laboratory in connection with the Q-Chem program.

From 1968 to 1974, Mr. McNea was a member of the U.S. Navy, advancing from Foreman to Machinist Mate First Class in the Submarine Service. He was stationed aboard the Fast Attack Submarine U.S.S GURNARD from July 1971 to the end of his enlistment. His major duties were in the chemistry and radiation protection areas. Mr. McNea completed the U.S. Navy Nuclear Power School, Nuclear Power Plant Operator Training, and Engineering Laboratory Technician Training courses. In 1975, he joined NWT as a Consultant. Since that time, he has contributed to numerous consulting and research projects at BWRs and PWRs including measurements of oxygen, peroxide, and ECP at BWRs and primary and secondary chemistry monitoring programs at PWRs. He also has been involved in numerous test programs on condensate polisher system performance, radiotracer feedwater flowmeter calibrations at the Monticello, FitzPatrick and Limerick BWRs, turbine performance tests at Ringhals 1, and tracer MCO tests at Millstone, McGuire, Catawba, and Calvert Cliffs.

Mr. Helmholz began his nuclear industry career in 1951 at Hanford. He subsequently joined the Case Institute of Technology where he organized the radiochemistry program and taught courses in nuclear chemistry. After several years at KAPL and at NRTS at Idaho Falls, where he supervised the S5G chemistry laboratory, he joined GE-Vallecitos and assumed responsibility for design and performance of chemical test programs at operating BWRs. Since joining NWT in 1981, he has had responsibility for numerous projects in the chemistry and radiochemistry areas including development of radioanalytical procedures, laboratory reviews, training course development and presentation, and assessments of solid waste radioassay techniques, radwaste dose rate to curie conversions, ventilation monitoring, and fuel failure modes.

Dr. Palino has been a Principal Consultant with NWT since 1979. From 1974 to 1979, he was associated with General Electric's Nuclear Energy Division. Prior to joining GE, Dr. Palino taught chemistry, radio-chemistry and engineering courses at San Jose State University, at Harvey Mudd College and at the Federal University of Rio de Janiero. Since joining NWT, Dr. Palino's responsibilities have included technical management of PWR primary and secondary system chemistry studies and BWR radiation level assessment and control programs. He also has developed and presented training courses for BWR and PWR chemistry staffs and has worked in the areas of radwaste treatment, volume reduction, tracer calibration of flowmeters, condensate demineralization and quantification of moisture carryover from PWR steam generators.

Mary joined NWT Corporation in March 1989 as a laboratory chemist. She currently administers the NWT Q-Chem program, a nuclear utility interlaboratory validation effort to comply with 10CFR50 requirements. She also trains NWT laboratory personnel, authors and reviews laboratory procedures, oversees the NWT laboratory safety program and manages the laboratory when required. In addition to her laboratory responsibilities, Mary has participated in several moisture carryover measurement programs at PWRs using the Na-24 radiotracer technique.

Since joining NWT in 2000, Mr. Leonard has participated in a variety of activities relative to impurity transport and corrosion in PWR and BWR systems. He has been involved primarily in crevice and surface solution chemistry, hideout return, corrosion product transport, and PWR fuel deposit modeling efforts. He has participated in several plant gamma scans and a feedwater flowrate/moisture carryover tracer evaluation. Mr. Leonard also has responsibility for test loop operation and sampler/ECP electrode fabrication. Contact Mr. Leonard at maleonard@nwtcorp.com maleonard@nwtcorp.com

Mr. Miller joined NWT in 1981. Currently, he is supervisor of the NWT laboratory and is responsible for application and development of advanced analytical procedures to support NWT and client needs. His emphasis has been on methods development for analysis of low concentration impurities in power station waters including adaptation of graphite furnace atomic absorption and ion chromatography techniques. His accomplishments in related areas include development of a radiotracer based resin leakage procedure and modification of commercial TOC instrumentation for in-line plant applications. Mr. Miller is responsible for NWT's in-house laboratory QA/QC program and its BWR and PWR Q-CHEM programs which provide samples of unknown concentration for plant chemist analysis to assist utilities in demonstrating conformance to 10CFR50. Over 50 plants currently are participating in this program in partial satisfaction of 10CFR50 requirements. Mr. Miller also provides customized training at utility sites on low level impurity analyses in nuclear systems employing primarily ion chromatography and atomic absorption techniques.
