WebPurpose and Operation of Reactor Vessel Head Venting System (RVHVS) To remove non-condensable gases or steam from the reactor vessel head. Vents to containment atmosphere. Two vent lines with orifices to limit the flow of H2 and limit flow to within the capacity of one CCP in the event of a rupture or inadvertant opening. Webhead vent penetration in place of the manually delivered tool used previously. Similarly, decontamination is simplified because of the overall decrease in inspection equipment located within the reactor head stand and because the Gemini robots can be relocated during repairs.

WebRPV head is mainly determined by the reactor compartments venting system. The contribution of convective in-vessel heat transfer is of the order of 10%. The venting system was modelled by a given heal: transfer coefficient of 12.5 W,/m 2/K as agreed in [4]. 4. Scenario without creation of a steam bubble under RPV head WebFeb 22, 2016 · The center of any chemical process is the reactor, where chemical reactions are carried out to transform feeds into products. Reactor design is a vital step in the overall design of a process. It is important to ensure that the equipment specified will be capable of achieving the desired yields and selectivity.
