In Part five.twelve, "Primary Steam, Steam Generator Blowdown, Extraction Steam, and Nitrogen and Hydrogen Devices," of Appendix A into the LRA, the applicant explained the recognized methods, their supposed functions, and the linked constructions and parts of every technique that are throughout the scope of license renewal, and identified which of All those structures and elements are topic to an AMR. As described while in the LRA, the applicant's major steam (MS) Process AMR report includes the extraction steam and nitrogen and hydrogen units in its scope. The steam generator blowdown process (SGBS) is considered Element of the MS procedure as well as the parts on the SGBS that are Within the containment are A part of the scope of the area of the LRA as Section of the main steam technique.
The RMS comprises the next forms of kit: piping/tubing (supplies process flowpath and maintains stress boundary), pumps (offer motive force to move fluids getting sampled), valves (give containment isolation and technique alignment/isolation), filters (filter air to protect downstream components), and instrumentation/factors (deliver facts to operators and signals to regulate machines).
Detect smoke, retain ventilation in unaffected zones, and remove smoke/offer fresh air to afflicted zones in the celebration of a hearth within the Management space or cable spreading rooms.
Drains from your RCS piping to your radioactive waste processing method are presented for draining the RCS for maintenance operations. A link is likewise offered over the quench tank for draining it to the radioactive waste processing program next a relief valve or security valve discharge.
Radioactive miscellaneous waste sampling subsystem hand valves inside the invested fuel pool filter and demineralizer sampling strains such as the sample coolers; and
The New Gas Elevator--The new gas elevator is utilized to reduce new gas assemblies in the SFP exactly where the invested gas dealing with machine (SFHM) will be able to grapple and transfer the gas to the specified pool area. The new gasoline elevator is found during the Device one close of the SFP.
Within the July 2, 1999 letter, the applicant mentioned which the bodies with the solenoid valves inside the containment spray method usually do not complete a tension boundary meant function, i.
Function a pressure boundary or perhaps a fission products retention barrier in the function of the design-basis occasion.
To maintain electrical continuity and/or deliver protection of your electrical method, To keep up the stress boundary of the process (liquid and/or gasoline), and
The team concentrated its evaluation of your applicant's approach for defining the applicability of the AMR for your containment construction and containment technique on the issue of irrespective of whether the necessities and intent of 10 CFR 54.four and 54.21(a)(one) are fully complied with. The team reviewed Every in the 44 element sorts noted higher than to the containment structure and containment method to verify that this stuff are Portion of the containment framework plus the containment method. The personnel even further verified which the applicant experienced not omitted any merchandise from an AMR which can be Element of the containment framework and containment process, and that perform an supposed perform devoid of relocating pieces or and not using a transform in configuration or properties and so are not issue to replacement dependant on a qualified life or specified time frame.
The applicant also indicated that some components that happen to be popular to several programs have already been included in the separate commodity stories that deal with All those blog elements for the whole plant. As a result, the subsequent elements weren't included in the individual system sections:
The next FHE and HLHC components are resolved for his or her structural meant purpose(s) as parts of the building in which They're housed in Segment 3.3 of Appendix A into the LRA, and therefore are, for that reason, not reviewed in this section: Personal computer girders
In accordance with Element official site fifty four, BGE submitted information and facts of their renewal application that identifies all plant programs, structures, and elements: (one) that happen to be check over here basic safety-relevant; (two) whose failure could impact basic safety-related capabilities; and (three) that happen to be relied on to reveal compliance Using the NRC's polices for fireplace security, environmental qualification, pressurized thermal shock, anticipated transients with no scram, and station blackout. BGE's application also describes how the results of aging will be managed in this kind of way the intended capabilities of People constructions and factors might be taken care of for the twenty-year period of prolonged Procedure.
All through the first step of its analysis, the workers reviewed parts of the UFSAR, such as the movement diagrams for the DFO procedure, to determine if there have been any parts on the DFO program piping or other components Which may perform supposed features which were not explained during the LRA. Essentially all portions of the DFO system have been decided to carry out at the very least just one intended perform and, as a result, fundamentally all parts and factors of your DFO method are within the scope of license renewal and therefore are determined therefore by the applicant, either in Area 5.seven of Appendix A to your LRA or in other sections on the LRA. The team reviewed the few remaining elements from the DFO technique to verify that they do not have any meant features. The personnel also reviewed the UFSAR to determine if there have been any extra system capabilities which were not identified as meant features during the LRA and confirmed that Individuals supplemental features did not fulfill the scoping prerequisites of ten CFR 54.4. Nonetheless, while in the LRA, the applicant discovered a non-safety-linked line from FOST No. 21 to diesel making room squander oil gathering tank (WOCT) No. eleven as not within the scope of license renewal. The applicant also did not detect or examine a non-protection-related line in the concrete enclosure of FOST No. 21 that, according to the UFSAR, can be utilized to provide the EDGs within the event from the FOST's rupture.
