The PALLAS-reactor is a pool-type reactor, which is able to deploy its neutron flux more efficiently and effectively than the HFR.  The most important feature of the PALLAS-reactor is its operational flexibility. The core of the reactor can be set up very flexibly for production of various medical isotopes and hence respond to changing markets.

In the design process special attention will be focused on the reactor core and all nuclear systems involved. To get the appropriate design the PALLAS organisation has prepared a document with functional requirements. This is called the “Technical Requirements” (in short TR). This document will be used by the designer (Designer Nuclear Island, DNI) – the Argentinian-Dutch company ICHOS (INVAP and the TBI companies Croonwolter&dros – Mobilis) – to make the final design of the PALLAS-reactor.

The design process includes many interim steps towards the final design. Every substep will be extensively tested according to the latest international regulations of the International Atomic Energy Agency (IAEA) and the specific Dutch requirements regarding the safety of the design and business operations.

Thus, the reactor building (the containment) has to be designed to withstand potential external hazards, such as airplane accidents or earthquakes.
