NPD Reactor Tour


Take a visit to Canada's first power reactor!

The 20 MW Nuclear Power Demonstration (NPD) reactor was Canada’s first nuclear power reactor to supply electricity to Ontario Hydro’s electrical distribution grid. NPD began operations in 1962 and for 25 years served as an important training facility for future reactor engineers and operators. 

The reactor was permanently shutdown in 1988, and is presently in the Storage with Surveillance phase of decommissioning under a licence issued by the Canadian Nuclear Safety Commission (CNSC).

This tour will provide you an opportunity to learn more about the former operations of this facility, and the proposed in-situ approach to decommission the reactor over the coming years.

The NPD site is located on the south bank of the Ottawa River near the town of Rolphton Ontario, roughly 3 km downstream from the Des Joachims Generating Station and approximately 25 km upstream from the Chalk River Laboratories (CRL).

The tour has reached capacity. Thank you for your interest.

For the 2017 Open House, we are able to offer guided tours of the reactor.   Space on these tours is limited; should you wish to attend please indicate your interest on the registration form.  If space is available, we will be in touch by email with the specific details to complete your registration and identify your tour time.

Transportation to and from the NPD reactor site is not provided. Specific access instructions will be provided by email should you be selected for a tour.

This is a one-hour walking tour, and does require some extended periods of standing. As such, it is not recommended for those with mobility concerns.  Please note that you must be at least 12 years old to participate.
