Question

All alterations to boilers and pressure vessels and all repairs that are not inspected and certified by an owner-user must be?

Option 1: Registered with ABSA.

Option 2: Approved by the manufacturer.

Option 3: Documented in the equipment log.

Option 4: Conducted by ABSA.

Answer 1

Repairs and alterations to boilers and pressure vessels not certified by an owner-user must be registered with ABSA to adhere to safety regulations.

Step-by-step explanation:

All alterations to boilers and pressure vessels, as well as repairs that are not inspected and certified by an owner-user, must be registered with ABSA (Alberta Boilers Safety Association). It’s essential for ensuring compliance with safety regulations and standards. Notably, Option 3: Documenting in the equipment log is also an important step, but this by itself does not suffice for compliance purposes—all such changes must still be officially registered.

The reactor, steam generator, and condenser are three water systems that are kept separate to ensure the integrity and safety of the system. In particular, the water within the reactor is radioactive and remains within a containment structure to prevent contamination, while the water in the steam generator and the condenser is nonradioactive. This is fundamental in the operation and maintenance of these systems.
