93 U.S. Senate Committee on Environment and Public Works Statement of Edward E. Purvis, III Assisted by Dr. Marvin Goldman July 22, 1992 57-583 - 92 - 4\
94 Statement of Edward E. Purvis, III Principal Engineer Los Alamos Technical Associates, Inc. July 22, 1992 Mr. Chairman, my name is Ed Purvis. I am a principal engineer with Los Alamos Technical Associates (LATA), an environmental sciences and engineering firm that provides technical services to industry and government agencies. Our principal work is in the fields of hazardous and radioactive materials handling and processing, national security, the environment, and nuclear safety. LATA has appeared in the Inc. 500 . an elite group of the nation's fastest growing companies, and has been in the Enoineering News Record's list of the top 500 design firms since 1 981 . programs in Russia and in Ukraine. LATA is cun-ently involved in nuclear safety and nuclear cleanup In 1986, I led the Department of Energy's Analysis Team's work to understand the Chernobyl-4 accident. Subsequently, we did extensive and detailed analyses and reviews of the safety of the Chernobyl type reactors, of the various models of WERS (Soviet designed pressurized water reactors) and other Soviet designed nuclear facilities. Results were published in DOE/NE-0076, which addresses the Chernobyl accident, and DOE/NE-0084 and DOE/NE-0084 which address WERs. My recent activities have included waste management, nuclear safety, and work related to cleaning up the aftermath of the ChernobyI-4 accident. I was assisted in the preparation of this statement in regard to health effects of the Chernobyl accident by Dr. Marvin Goldman, who is extremely knovirfedgeable in this area. He is the leader of the US/USSR joint working group on health effects. He is Emeritus Professor of Radiology at the University of California at Davis, recipient of the Health Physics Society's Distinguished Scientific Achievement Award, and has chaired many committees assessing health effects of radiation. I appreciate this opportunity to discuss the Chernobyl accident and its results, the current status, the continuing threat posed by the results of the accident, particularly in the area near the sarcophagus covering Chemoby1-4. It Is necessary to understand the accident sequence in order to understand the resulting and current situation.
