nuclear energy sounded wonderful when it was first developed,
of its expected low cost lack of
pollution. Safety was a concern and was taken seriously _
careful precautions were usually taken, and in most cases these did'actually
result in a low chance of an accident. , nothing is perfect,
including safety systems, and when problems do happen, the consequences
are extremely serious. , although actual operation of a
nuclear reactor produces little visible pollution, disposal of the radioactive
materials that are produced is extremely difficult and expensive,
consequently nuclear power is now considered too
expensive in many countries. , many governments have
stopped planning to build more nuclear reactors. This example clearly
shows that the miracle of yesterday may become the disaster of tomorrow.
Not every scientific advance has the expected result.
