PWR Operational Chemistry: Problem Assessment and Diagnosis

The PWR Operational Chemistry course was developed by NWT to assist plant and corporate chemistry personnel in the following areas:

This course has been developed by senior NWT personnel who have been involved in PWR and BWR water chemistry, corrosion, water treatment, and activity transport control for 20 or more years. Their experience base has been complemented by consideration of the underlying chemistry and engineering principles in each area of instruction. Because of the nature of the course, senior NWT personnel provide all instruction (see Class Lecturers).

The course is intended for PWR chemistry personnel involved in data review, problem identification and diagnosis, and development of corrective actions.

Class Lecturers

Steve Sawochka

Dr. Sawochka currently is President of NWT Corporation. He has been involved with consulting and R&D projects in the fields of water chemistry, water treatment, corrosion, and radwaste processing in BWR and PWR systems for over 50 years. He previously was Manager of Water Chemistry Development for General Electric's BWR Systems Department. Dr. Sawochka has authored numerous publications in the referenced areas and has been an active member of EPRI committees that have developed guidelines for BWR and PWR chemistry control.

Jerry Palino

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.

Hank Helmholz

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.
