As explained in Appendix A towards the LRA, several techniques Use a containment isolation perform and, for that reason, have containment isolation valves, containment penetrations, and related piping and test connections. The elements that conduct the containment isolation function in programs which might be evaluated in other sections on the LRA are provided in All those sections.
The applicant also stated that some components from the EDG system which have been common to numerous systems happen to be included in the separate commodity report sections in the LRA which tackle Individuals parts for the whole plant. Therefore, the following elements weren't A part of the person technique sections:
In 1982, the NRC held a workshop on nuclear electric power plant growing old, in anticipation with the curiosity in license renewal. That led the NRC to determine a comprehensive software system for nuclear plant getting older study (NPAR). Based on the effects of that analysis, a technical evaluate team concluded a large number of aging phenomena are commonly workable and don't pose technical challenges that may preclude life extension for nuclear ability vegetation.
The turbine building with the CCNPP is widespread to both models and is particularly oriented parallel towards the Chesapeake Bay shoreline concerning the North Service Building as well as auxiliary building. It's a steel structure with metal siding supported on bolstered-concrete foundations. The turbine building is often a seismic Category II composition.
People structural supports for piping, cables, and factors from the RCS that happen to be subjected to an AMR are evaluated for the results of growing old in Section 3.
For submit-accident checking-- Give facts accustomed to evaluate the condition in the plant and its environs through and next an accident.
On The idea of your meant method features mentioned over, the applicant emphasised that the portions of your ABHVS process which might be in the scope of license renewal contain all safety-connected factors while in the process (electrical, mechanical, and instrumentation) as well as their supports. The applicant explained the subsystems and these associated equipment as accumulators, Examine valves, and dampers. The applicant recognized forty six gadget kinds. With the 46 unit varieties connected with the ABHVS program the applicant recognized twenty five system varieties that have only active capabilities and do not demand an AMR. With the 46 unit styles, 10 usually do not involve an in depth evaluation of precise getting old mechanisms mainly because they are thought of Element of a posh assembly.
As described earlier mentioned, the employees has reviewed the information in Part five.1 of Appendix A on the LRA and the extra facts submitted by the applicant in anchor reaction to your staff members's RAIs.
On The idea in the meant functions listed earlier mentioned, the portions from the RMS which might be identified by the applicant as in the scope of license renewal incorporate the next tools sorts: piping, factors, ingredient supports, instrumentation, panels, and cables related to the next radiation monitors: containment location radiation monitors, containment significant-vary gamma radiation monitors, wide-assortment effluent gasoline radiation screens, containment environment radiation screens, CCS radiation check, SRW method radiation monitor, Manage place ventilation radiation observe, and principal steam effluent radiation monitors. The shaded areas of Figures five.14-one by means of five.14-8 of Appendix A for the LRA suggest the portions of the system within the scope of license renewal. The applicant determined a total of 33 gadget styles inside the scope of license renewal for This technique.
To offer air flow for, and remove possibly radioactive contaminated air from, the ECCS pump home in reaction into a find here DBE;
Deliver structural and/or purposeful guidance to non-safety-associated equipment whose failure could right stop satisfactory accomplishment of any of your essential protection-similar capabilities; and
The workers reviewed portions in the UFSAR, which include Segment nine.eight, "Plant Ventilation Programs," to determine if there have been any portions from the program the applicant did not identify as throughout the scope of license renewal that should have been so identified. The staff members also reviewed Segment nine.eight on the UFSAR to determine if there were any protection-connected technique capabilities which were not discovered as intended capabilities while in the LRA and to determine if there were any buildings and components getting intended features that might are already omitted from thing to consider inside the Our site scope of license renewal.
The team reviewed this area with the LRA to ascertain whether or not There is certainly fair assurance the applicant has correctly discovered the RPVs and the CEDMs/electrical system components and supporting structures throughout the scope of license renewal in accordance with ten CFR fifty four.
On The idea from the supposed capabilities listed over, the parts of your CVCS that are throughout the scope of license renewal include all factors (electrical, mechanical, and instrument) and their supports together the subsequent technique flowpaths:
