The staff members has reviewed the information in Section five.1 of Appendix A towards the LRA and additional information and facts submitted through the applicant in response towards the team's RAIs.
In the event that the IA and PA compressors come to be unavailable, for example pursuing load shedding on account of a security injection actuation sign (SIAS), two protection-similar SWA compressors will provide a backup supply of compressed air to most safety-related components. These compressors are mechanically begun on receipt of the SIAS and can be operated from a neighborhood panel. The SWA compressors supply the SWA header that distributes air to all saltwater (SW) isolation valves for that service h2o warmth exchangers, element cooling heat exchangers, and also the crisis Main cooling program pump home air coolers.
On the basis of the critique, the personnel finds that there is acceptable assurance that each of your miscellaneous tank and valve enclosures that household SR products with the CCNPP web site have been appropriately recognized because of the applicant as staying within the scope of license renewal in accordance with the necessities of 10 CFR fifty four.4.
The turbine creating for your CCNPP is frequent to both models and is oriented parallel into the Chesapeake Bay shoreline between the North Service Making as well as the auxiliary making. It is a steel composition with metallic siding supported on strengthened-concrete foundations. The turbine making is a seismic Class II construction.
Throughout the first step of its analysis, the employees reviewed portions of your UFSAR, such as the flow diagrams to the EDG procedure, to determine if there were any method components that the applicant didn't detect as inside the scope of license renewal but that were required to carry out among the discovered supposed functions of your EDG procedure.
As described in the LRA, the MS procedure (which include SGBS piping and isolation valves, as applicable) serves because the stream path for SG output steam to the main significant-pressure turbines, the humidity separator reheaters, key feedwater pump turbines, the AFW pump turbines, and the steam seal regulator. The procedure also this website offers overpressure protection to the SGs and automatic removal of nuclear steam offer process (NSSS) stored Vitality and wise heat subsequent a turbine and reactor trip.
As explained in Appendix A on the LRA, the functionality on the RCS is to get rid of heat from the reactor Main and reactor inner parts and transfer it towards the secondary (steam generating) procedure. The RCS of each unit, which is situated fully inside the containment building, consists of two warmth transfer loops related in parallel across the reactor strain vessel (RPV). Just about every loop has 1 steam generator (SG), two reactor coolant pumps (RCPs), connecting piping, and move and temperature instrumentation.
The employees has reviewed the information submitted in Area five.eight of Appendix A to your LRA and additional information and facts submitted via the applicant in reaction towards the team's RAIs.
One machine kind, flow transmitter, consists of 16 stream transmitters which can be inside the scope of license renewal.
For environmental qualification -- Offer info used to This Site evaluate the environs and plant disorders for the duration of and just after a collision.
Some elements inside the containment program are frequent to a number of other plant methods (e.g., structural supports address for piping, cables, electrical Handle, and energy cabling) and are actually mentioned by the applicant in independent sections on the LRA that deal with Individuals factors as commodities for the whole plant.
This SER summarizes the effects from the workers's protection assessment of the Calvert Cliffs license renewal software and delineates the scope with the technical information thought of in analyzing the safety elements of its proposed operation for a further 20 years beyond the time period of the current operating license.
The applicant has explained the security-relevant percentage of the following subsystems that perform their meant perform without transferring areas or without modifications in configuration or Attributes and classified those constructions and factors into product varieties topic to an AMR (detailed in Table five.thirteen-1 of Appendix A to your LRA).
The ECCS pump rooms are served by a air flow subsystem to control area temperature and provide proper cooling of the security injection and containment spray pumps. The subsystem is made of a person cooling unit for each ECCS pump place, cooling unit enthusiasts, and an ECCS pump room exhaust program which contains a roughing filter, a HEPA filter, a charcoal filter, and dampers. Saltwater is circulated with the air cooling coils to eliminate heat.
