Bruce Power was paid around $60 million in 2010 for contracted, but unused power. This highlights the importance of having a clear understanding of power generation costs.

The contracted price for electricity generated at Bruce Power began at CA$65.73 per megawatt-hour (MWh) in 2016. This price is adjusted annually to account for inflation and wage growth.

In addition to the base price, Bruce Power receives a small payment for its ability to curtail up to 2400 MW of generation via steam bypass operation during periods of surplus generation. This unique ability allows the company to optimize its power output.

The price of electricity generated at Bruce Power is expected to increase in steps to cover individual reactor refurbishment costs. Each increase will start 12 months prior to the start of each refurbishment and will last only until the refurbishment costs have been recovered.

The average price per MWh that will be paid to Bruce Power for all electricity generated from 2016 to 2064 is estimated to be approximately CA$80.6/MWh in 2017 dollars. This is a significant increase from the contracted price of CA$65.73/MWh in 2016.

In comparison, the estimated average price of nuclear electricity from all three Ontario nuclear plants during the same period was CA$80.7/MWh in 2017 dollars. This highlights the importance of considering the overall cost of power generation.

Cobalt-60 production is a significant aspect of Bruce Power's operations. The company has been producing Cobalt-60 since the 1980s.

Bruce Power produces Cobalt-60 by using adjuster rods made of Cobalt in their CANDU reactor. These rods are transmuted into Cobalt-60 via neutron activation.

The Cobalt-60 adjuster rods are harvested after one to three years of use and are later processed into sealed Cobalt sources by Nordion.

As of 2007, Bruce supplied over 40% of the world's Cobalt-60, making it the single largest supplier. This rose to over 50% by 2016.

Bruce Power began producing High Specific Activity (HSA) Cobalt in 2016, designed for highly specialized medical uses such as cancer treatment.

The Bulk Steam System was a massive operation that ran from 1972 to 2006. It was one of the largest in the world, producing 5,350 MW of medium-pressure process steam.

This system was incredibly complex, with over 6 km of piping. I can only imagine the challenge of maintaining such a vast network.

The Bruce Power nuclear plant has been at the center of a significant event in the past, the Northeast Blackout of 2003. During this blackout, three Bruce B units continued running at 60% reactor power and 0% grid electrical power for hours.

These units were able to keep running because they had steam bypass systems that allowed the reactor output to be decoupled from the generator electrical output. This was a crucial design feature that enabled the plant to operate independently of the grid.

The Bruce A and B stations were designed to operate indefinitely while disconnected from the grid, a testament to the plant's robust design and engineering.

The Northeast Blackout of 2003 was a significant event in the history of power generation. Three Bruce B units continued running at 60% reactor power and 0% grid electrical power for hours.

These units were able to do so because they had steam bypass systems designed to de-couple the reactor output from the generator electrical output. This allowed them to operate independently of the grid.

The three units were reconnected to the grid within 5 hours, showing that nuclear plants can operate indefinitely while disconnected from the grid, provided specific engineered systems are included in the plant design.
