A fundamental requirement to make HTMR100 plants viable especially for remote areas, due to its transportability. Centralized manufacturing facilities with Quality Assurance (QA) procedures in place will be responsible of building the Reactor Pressure Vessels (RPV), which later will be transported to the reactor sites. This transportability requirement imposes a limit in the RPV outer diameter, which in turn limits the maximum diameter of the pebble bed as well as the height.
The steam turbine and helium blowers along with various other components will be purchased straight off the shelf from a number of different suppliers; this modularity allows the HTMR100 Nuclear Power Plant to be built in a short period of time. The construction of the buildings can continue independently from the supply of the critical components. Most of the sub-systems will be constructed in skid mounted units, ready for coupling when delivered to site.
