It was a busy July meeting for the Cleve District Probus Club with plans for the district rally outlined by entertainment co-ordinator David Reed.
Prior to morning tea four new members were inducted into the club by president Shirley Dennis.
Anthony Page who has retired in Cleve was introduced by Mary Leonard, Dean Darling was introduced by Rex Kobelt who said the former builder had been in the district a long time.
David and Janys Asser lived in Salisbury for many years before recently moving to Cleve.
Ms Asser was formerly in partnership in a tool making business and Mrs Asser was a florist. They were introduced by Maurice Smith.
Guest speaker was Momina Butt from Saskatchewan, Canada.
The daughter of Cleve doctor Mateen Butt, Miss Butt recently graduated with an Honours Bachelor of Science in Physics with a concentration in Nuclear Science.
Miss Butt was surprised to find Australia had no nuclear power plants, yet it is one of the biggest sources of uranium in the world.
Nuclear Power provides 5.7 per cent of the world’s power and 13 per cent of the electricity.
There are 437 nuclear plants in use world wide plus another 60 under construction.
She said it was the cheapest source of energy without harmful emissions and human error has been the main cause of nuclear accidents.
Miss Butt explained her research on three accidents, Tokaimura Japan in 1999, Three Mile Island USA 1979 and Fukushima Japan 2001.
All accidents revealed design faults, location problems and communication difficulties between workers and experts.
Tokaimura Japan 1999 was a category seven accident. There was a major release of energy and one person died.
Three workers were enriching uranium making it stronger causing uncontrolled nuclear fusion.
Fukushima, Japan March 11, 2001 was a category seven accident, caused by an magnitude nine earthquake followed by a tsunami.
There were five plants in the disaster zone and a wall had been built in case of a tsunami but it was not high enough and the plant was disabled and two workers died.
Backup generators were flooded and there was nothing to control the plant. There was discussion among the managers and operators about evacuation.
Two days later a valve was opened and it exploded, releasing radioactive gas into atmosphere.
TAt hree Mile Island USA March 28 1979, while cleaning out grids with water pressure, a decision was made to turn water off, causing a partial melt down of the reactor core, and eventual release of radioactive gases.
Judy Kraehe gave a vote of thanks for a most interesting and confident young speaker.
