Reports that ten years after a marathon public inquiry and dcs ite an UMXpetted final obstacle, Sizewell B is due to be connected to tKe grid early next year. The Sizewell B station staff have set themselves challenging targets, as they aim to make Sizewell one of the top ten nuclear power stations in the world during the first year of operation. France’r first N4 unlt at Chooz B neara rtartup 95/00429 Rippon, S. Nuclear News, Jul. 1994, 37, (9), 42-43, 46.

Reports that during a recent instrument calibration at Georgia Power Company’s Edwin I. Hatch nuclear plant in Baxley, Ga., a acking nut from an instrument isolation valve came loose, depressurized tge line! actuated the scram instrumentation, and caused a reactor scram. On a different occasion, a technican set a iece of monitoring equipment on a rack near another instrument line. -!he monitor fell off the rack, hit a valve, depressurized that instrument line, and caused another reactor scram. From 1991 through 1993,7 of 18 reactor scrams at Hatch-l, a 742-MWe (net) General Electric boiling water reactor,and at Hatch-2, a 761~MWe GE BWR, were caused by the failures of a single piece of equi ment. In an effort to reduce plant downtime and identify likely initiators oP.smgle-failure scrams, Hatch management has assembled a Single Point Failure Scram Analysis Team. 95100432 lgnallna RBYK-1500: A source book Almenas, K. et al., Lithuanian Energy Institute, Breslaujos 3, 3035 Kaunas, Lithuania, Free of Charge, 129 pp. The authors are from the Ignalina Safety Analysis Group.

Reports that the UKAEA e ovemment Division have been tasked with decommissioning the redundant facilities created by forty years of nuclear development in the UK. 95100434 Llrt of scheduled outagea at US. nuclear power plants Nuclear News, Jul. 1994, 37, (9). 33-37. The list includes refuelling, mid-cycle, and maintenance outages at U.S. nuclear power plants that are scheduled to occur anytime from July 1994 through the end of June 1995. 95/00435 Los Alamos Jolnte Rurslan tranamutatlon efforl Nuclear News, Sep. 1994, 37: (11), p. 103. Reports that Los Alamos National Laboratory will collaborate with Russian physicists to design particle accelerators to transmute weapons-grade lutonium and commercial nuclear waste into stable isotopes, under a grant !rom the Moscow-based International Science and Technology Center. 95100436 Numrrlcal study on the turbulence structuree In closely spaced rod bundle rubchannels Wu, X. Numerical Heat Transfer, Part A, Applications, Jun. 1994, 25, (6), 649-670. Fully developed turbulent tlow through simulated rod bundle subchannels formed by a rod-trapezoidal

This column, the final one in this series, presents the highlights of S. Israel’s report titled ‘Insights from Common-mode Failure Events’. His study looked at 62 common-mode failure events, 50 of which occurred in 1990.
