CROSS-REFERENCE TO RELATED APPLICATION BACKGROUND USE OF ISOLATION CONDENSER AND/OR FEEDWATER TO LIMIT CORE FLOW, CORE POWER, AND PRESSURE IN A BOILING WATER REACTOR [0001] The present application claims priority to U.S. Application No. 16/38 1, 147, filed April 11, 20 19, the entire contents of which are incorporated herein by reference. [0002] The present disclosure relates to the use of an isolation condenser and / or feedwater to limit core flow, core power, and pressure in a boiling water reactor. [0003] This section provides background information related to the present disclosure which is not necessarily prior art. [0004] A boiling water reactor is a light water nuclear reactor used for the generation of electrical power. Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. The steam is directly used to drive a turbine after which it is cooled in a condenser and converted back to liquid water. This water is then returned to the reactor core, completing the loop. [0005] In conventional boiling water reactors, the feedwater enters into a downcomer or annulus region and combines with water exiting the Field Description of Related Art
