The UK’s Dounreay Site Restoration Limited (DSRL) announced on 5 August that some 68t of the liquid metal coolant, a blend of sodium and potassium (NaK) have been removed from the primary circuit of the Dounreay Fast Reactor (DFR) and destroyed over 10 years. Most of the NaK had been removed by 2012, since when work has been under way to remove the last of the coolant from the difficult to access pipework and base of the structure.

Battelle Energy Alliance, LLC (BEA), Management and Operating Contractor of the Idaho National Laboratory, seeks an expression of interest from qualified subcontractors to design functionally equivalent replacements for four nuclear instrumentation subsystems at the Advanced Test Reactor (ATR). The four subsystems are 1) the Log Count Rate Meter (LCRM) subsystem, 2) the Wide Range Neutron Level (WRNL) subsystem, 3) the Neutron Level (NL) and NL No. 8 subsystem, and 4) the Log-N Period subsystem. The following components are included in the design effort: the detectors, displays/recorders, amplifiers, associated electronics of each subsystem, and all appropriate equipment interfaces.
