is nuclear power reliable?

yes extremely ; its generates a lot of electricity when we want it

what is the key disadvantage of nuclear power plants

they contain highly dangerous radioactive materials

what may happen if there is an accident with the nuclear power plants

the radioactive materials could be released into the enviroment - which would be disastrous

what has to happen to a nuclear power plant at the end of it's life

has to be decommissioned/dismantled

why does a nuclear power plant having to be decommissioned/dismantled a disadavantage

takes many years, and is extremely expensive

what is done with the dangerous large amounts of radioactive waste generated from nuclear power plants

stored for thousands of years

why does the radioactive waste have to be stored for thousands of years

so it's safe

is this a disadvantage?

yes
