Summary
Currently, the 900 MWe class Improved Pressurized Heavy Water Reactor (PHWR),
which is a type of CANDU reactor based on the systems and components of
operating CANDU plants, is under development. The improved PHWR has a 480 fuel
channel calandria, uses 37 element natural uranium fuel bundles and has a single unit
containment Adaptation of a steel-lined containment structure and improved
containment isolation systems permit a reduced exclusion area boundary (EAB)
compared to the existing larger capacity CANDU reactors (Darlington, Bruce B).
The Improved PHWR buildings are arranged to achieve minimum spacing between
reactor units. Plant safety and economy are increased through various design changes
based on the operating experience of existing CANDU plants.

Abstract (About 300 words)
Currently, the 900 MWe class Improved Pressurized Heavy Water Reactor
(PHWR), which is a type of CANDU reactor based on the systems and
components of operating CANDU plants, is under development The improved
PHWR has a 480 fuel channel calandria, uses 37 element natural uranium fuel
bundles and has a single unit containment Adaptation of a steel-lined
containment structure and improved containment isolation systems permit a
reduced exclusion area boundary (EAB) compared to the existing larger capacity
CANDU reactors (Darlington, Bruce B). The Improved PHWR buildings are
arranged to achieve minimum spacing between reactor units. Plant safety and
economy are increased through various design changes based on the operating
experience of existing CANDU plants.
