Jovial,
have you got any idea of how much pressure is inside a nuclear reactor?
To me it's like a pressure cooker bomb ready to explode when neutron embrittlement causes the metal to break.

Quote:

Light water is used as the primary coolant in a PWR. Water enters through the bottom of the reactor's core at about 548 K (275 °C; 527 °F) and is heated as it flows upwards through the reactor core to a temperature of about 588 K (315 °C; 599 °F). The water remains liquid despite the high temperature due to the high pressure in the primary coolant loop, usually around 155 bar (15.5 MPa 153 atm, 2,250 psi). In water, the critical point occurs at around 647 K (374 °C; 705 °F) and 22.064 MPa (3200 psi or 218 atm).[7]

Waste can be treated with the CSIRO Sincrete process then deeply buried. Can’t see why costs would be prohibitive.

Building a sophisticated underground nuclear waste storage facility could cost up to $33 billion
.........
The total capital cost of constructing, decommissioning and then closing the facilities at the end of the 120-year life has been estimated at $41 billion

Reply #92 - Jul 24^th, 2017 at 9:43pm We already have the space underground in Broken Hill, Mt Painter etc. The waste depository can also handle the waste from more than one nuke reactor.

Nuclear has risks. So does coal fired power generation.

ohhh please. You want to try to compare the two?

What happens if Lucas heights were to leaks compared to a coal powered generator?

The new generation of nucs are very very safe.

How safe will the be when Kim jung Ill drops a missile on one? Or an earthquake tears one apart? And you have to store the waste for 100 000 yrs.

You don't think technology will advance enough in 100000 years, let alone 100 to deal with it?

The earth will have been converted to Islam by then so hopefully there's a huge nuclear disaster to wipe them all out.

Theres no need to use coal, Australia has some of the biggest gas reserves in the world with significant infrastructure in place to extract that gas. We also have huge untapped resources of solar energy. This is a no brainer , going nuclear would be plain stupid.
