Perma-Fix Announces Sixth Annual Nuclear Waste Treatment Forum

OAK RIDGE, Tenn., Dec. 7 /PRNewswire-FirstCall/ -- Perma-Fix Environmental Services, Inc. (Nasdaq: PESI; BSE: PESI; Germany: PES.BE) - today announced it will hold its sixth annual Nuclear Waste Treatment Forum December 11-14, 2006 in Nashville, Tennessee. This year's forum theme is how a small business can find big solutions to the complex waste management issues facing the nation's nuclear industry. With renewed national interest in nuclear power and the possibility of the United States return to reprocessing spent nuclear fuel, there is great interest in ensuring that complex waste streams can be properly and safely managed. Perma-Fix is an innovator in finding solutions for many of the wastes that have been generated from nuclear power and nuclear weapons development by working closely with waste generators to solve their problems.

The Nuclear Waste Treatment Forum is a venue where many of the nation's waste management experts can work together to share lessons learned and their experiences for dealing with waste streams and successful completion of clean- up projects. This year's conference brings together an exciting lineup of speakers to discuss innovations in nuclear waste treatment, regulatory issues, and how to cope with competing priorities and shrinking budgets. The last day of the three-day forum will include tours for two of the Company's Tennessee treatment facilities.

Dr. Louis F. Centofanti, Perma-Fix chairman and chief executive officer said, "Each year our Treatment Forum has grown in popularity. This year we will have nearly 200 experts from around the U.S. and Canada sharing their experience in dealing with the most challenging waste management issues for the nuclear industry. We have been successful in working with our customers to safely treat large volumes of their legacy waste streams, and as we move into the future we will deal with newly generated wastes that pose new challenges for Perma-Fix and other commercial companies in our industry."
