On the other hand, in the low flow areas, the dose rate generation may be largely controlled by particulate deposition leading to “hot ... sustainment thought process of rdsp
Monitoring for shaft cracks on reactor recirculation pumps
WebA review of the BWR recirculation pump seals was conducted as the first step in the possible development of a new pump seal with improved sealing capability and service life. The first task of this study was the identification of the major seal failure mechanisms. A new seal specification was written. Existing seal designs were then investigated. WebJan 1, 2024 · BWR/6 jet pump recirculation system (BWR/6, 1980). With the jet pump recirculation system it became possible to reflood the core region of the vessel up to the top of the jet pump. This also provided an ECCS safety improvement, in that no recirculation line break could prevent reflooding to the core up to this level. 4. WebPiping of reactor recirculation and residual heat removal systems were partly or entirely replaced with 316NG or 316L stainless steel at 12 BWR plants through 1999. The weld … sustainment thesaurus
