i l Nursery School Tots Entertain at Lions Christmas Party An entertaining Christmas pageant by the Bow- 19th at the Lions Centre. The group of youngsters manville Nursery School students was a highlight is shown above during a re-enactment of the story of the Bowmanville Lions Club's annual Christ- of Bethlehem, mas party held on Monday evening, December Science Lectures Start Jan. 17th at Durham The Durham Board of Education and Durham College College are again sponsoring a series of Science Lectures. The Science Lecture series was established six years ago to provide up-to-date information information on science and science-related topics of current interest. This year there will be talks on the issues of nuclear radiation, radiation, AIDS, computer security and factors affecting our long- term weather conditions. The first talk will be held on January 17 at 8:00 p.m. in the Durham College Lecture Theatre. Professor Kenneth G. McNeill will speak on "The Human Body and Nuclear Radiation." It is known that high doses of radiation will cause biological biological damage. At lower levels delayed biological effects can occur, and these effects will be discussed largely in the context context of nuclear explosions. The talk is most topical inasmuch as it will address many of the questions raised by the recent television spectacular "The Day After", which dramatized what could happen after a nuclear attack. Professor NcNeill lectures at the University of Toronto in the areas of physics and medicine. He is also a technical technical advisor for the Nuclear Contingency Plans at Pickering Pickering and Bruce Generating Stations. Other speakers in the Science Lecture Series include Dr. Stanley Reid of the Hospital for Sick Children on the topic AIDS, a baffling and deadly disease -- on February 7 at Henry Street High School in Whitby; Dr. Ron Mullin of tHe University of Waterloo on Computer Security Systems on February 28 at Durham College; and Terry Alsopp of Environmental Canada on El Nino and other factors affecting affecting our weather on April 10 at Henry Street High School in Whitby. All lectures start promptly at 8:00 p.m., and there will be informal discussion and refreshments refreshments following the presentations. presentations. The Durham Science Lecture Lecture series is coordinated by Ambrose Samulski of Durham College's Food and Drug Department; Joe Hircock, a Durham Board of Education Science Consultant; Alan Monks of the Dunbarton High School Science Department; Prof. Kenneth G. McNeill and Ron Ennis, Mathematics Consultant with the Durham Board. 1984 PLYMOUTH RELIANT Station Wagons... haul-ability and value!

Section Two The Canadian Statesman, Bowmanville, January 11,1984 5 Speaker Says Hydro Deserves Praise Not Criticism by Peter Parrott Ontario Hydro frequently finds itself on the front pages of newspapers for the wrong reasons, members of the Bowmanville Men's Canadian Club were told last week. Guest speaker George Wieckowski told the club that Ontario Hydro should be singled out not for criticism criticism but for praise. Mr. Wieckowski, an engineer engineer with 20 years of experience experience in the Canadian nuclear industry, spoke to the club last Wednesday, January 4, at the Trinity United Church. He is currently currently serving as quality assurance assurance superintendent at the Pickering Nuclear Generating Station. "I can speak to you about matters nuclear from first-hand knowledge," said Mr. Wieckowski. Wieckowski. He assured his audience that Ontario Hydro is doing a good job and he added that much of the criticism of Ontario Hydro is unjustified. unjustified. Referring to the latest mishap in which a tube at the Pickering Nuclear Generating Station ruptured ruptured and resulted in the shutdown of a reactor, Mr. Wieckowski noted that it is incorrect to call the incident incident a nuclear accident. He compared it to what happens happens when a car develops a knock in the engine and it is driven safely to a garage for repairs. During a question-and- answer session following last week's Canadian Club meeting, the guest speaker pointed out that the Atomic Energy Control Board sets a limit for the amount of nuclear nuclear radiation which may be released by power stations. stations. Ontario Hydro continually continually operates at less than one per cent of the amount of radiation it would be allowed to emit. Mr. Wieckowski said that he is proud of the way nuclear nuclear operators responded to the incident at Pickering and he credits their response response to first-class training. training. Each year, operators spend 10 days at a control room which can simulate various problems at a nuclear nuclear station. "The operators just went by the book and did everything right," said Mr. Wieckowski. But that incident has led to the closing of two Pickering Pickering units until the reasons for the ! mishap are discovered. discovered. By shutting down these units until the cause of the problem has been investigated investigated Hydro has been saddled with an increased financial burden. The utility utility must pay an additional George Wieckowski, an engineer with Ontario Hydro's Pickering Nuclear Generating Station, shows members of the Men's Canadian Club what a uranium fuel bundle looks like. The bundle in this photo does not contain any uranium. However, However, one which has been loaded with the material contains enough fuel to replace 400 tons of coal. Mr. Wieckowski was guest speaker at a meeting of the Bowmanville Men's Canadian Club on Wednesday, January 4. Shown here, from left, are; Bert Snowden; Mr. Wieckowski; Canadian Club President Lloyd Down, and Tom Pleasance. The guest speaker was introduced by Mr. Snowden and thanked by Mr. Pleasance. half million dollars every day to replace power from the closed Pickering reactors reactors with coal-generated electricity. In making the case for nuclear nuclear energy, the Ontario Hydro representative told the Canadian Club that nuclear nuclear power has three advantages. advantages. First of all, it is based solely on resources available within Ontario and eliminates the need to import costly natural gas or oil. Secondly, the industry is clean and safe. Moreover, nuclear energy is generated at about 60 per cent of the cost of coal-fired electricity. electricity. He noted that Ontarians are among the most energy- hungry persons in the world and yet they lack many home-grown resources for producing energy. He pointed out that only water power and uranium fuel are available within the province. province. In 1981, it cost Ontario $11 billion to import energy, Mr. Wieckowski noted and he added that nuclear energy will help Ontario reduce reduce its dependence on imported imported energy. "About six years ago, the government of Ontario decided the province province must make strenuous efforts to get off oil," said Mr. Wieckowski. The Hydro engineer also gave a brief description of how a nuclear power station station operates. He pointed out that the heart of the system system is the reactor which contains fuel bundles consisting consisting of uranium. The fuel is contained within tubes surrounded by heavy water. It is this heavy water which allows a nuclear reaction to take place and it is this reaction which produces heat. The heavy water is used to boil regular water, which turns into steam that powers the turbines used in generating electricity. CARNATION FLOWER SHOP HOSPITAL and SYMPATHY ARRANGEMENTS"**!^ Flowering Plants and Cut Flowers 623-7141 33 Division St., Bowmanville A single bundle of fuel contains enough energy to equal 400 tons of coal. A fuel bundle can be handled safely before it is installed in a nuclear reactor. However, However, when it is removed it is highly radioactive. The issue of radioactive wastes led to a few questions questions from the audience. The guest speaker noted that it is possible to dispose of this material in rocks that have been stable for millions millions of years. However, he noted that since the process used at generating stations extracts only one per cent of the energy contained in nuclear fuel, it may be ad- viseable to keep this mate rial available for re-proces- sing in the future. As for the dismantling of nuclear power stations once they wear out, Mr. Wieckowski noted that since 99.9 per cent of the radioactivity resides in the fuel, disposing of fuel is the main solution. Reactors could be disassembled and taken to special disposal sites, while the remaining building materials could be removed in conventional methods. "I believe that nuclear power can supply energy at a low cost for a long time to come," said Mr. Wieckowski. Wieckowski.
