The goal of the Integral, Inherently Safe Light Water Reactor (I2S-LWR) Research Project is to design a more inherently safe reactor. This reactor is capable of cooling the core with no external power and no operator action.[1] In the I2S-LWR design, micro-channel heat exchangers (MCHX) facilitate heat transfer from the reactor to the steam generation system (SGS), where steam is used to produce electricity.1, 2

The I2S-LWR design requires the use of a “flashing” drum to produce steam, and the flashing drum and its impact on the SGS must be evaluated for safety before it can be incorporated into future designs. If it can be demonstrated that using a flashing drum can increase the safety of a nuclear reactor, other future nuclear designs may also include a flashing drum in their SGS.
