Passive Autocatalytic Recombiner (PAR) Requirements for PWRs: Value Impact Assessment

Objective: Determine whether it is cost-effective to update the existing § 50.44 requirements on combustible gas control to require passive autocatalytic recombiners for all PWRs with large-dry containment buildings. Under this approach, a backfit would be required of licensees with plants that have large dry containments in that they would have to install PARs and maintain them for the duratio...

Ssrl Rf System Upgrade*

The Stanford Synchrotron Radiation Laboratory started its operation as a parasitic light source in 1973, becoming a fully dedicated user facility in 1992. A project was approved in 1998 to upgrade the storage ring to a third generation source. In order to sustain higher current in a tightly reconfigured magnetic lattice, it became necessary to upgrade the RF system from the present 5-cell cavit...

The LHCb Upgrade

Future flavour physics experiments will be required in the second half of the next decade to either elucidate the flavour structure of new particles discovered at the LHC or to probe new physics at the multi-TeV scale. The planned upgrade of the LHCb detector involves at least five years of operating at ten times the current design luminosity, i.e. at about 2×10 33 cm −2 s −1. The aim is to col...

Luminosity Upgrade of Hera

After six years of operation the electron proton collider HERA had reached a luminosity of 1:4 10 cm s , very close to the design value. We present an overview on the HERA upgrade project that pursues the goal to further increase the luminosity three-fold by the year 2000. The increase is achieved by reducing the beam cross sections at the IP to 120 30 m (RMS values). If furthermore design curr...
