The Zarya module is 41.2 feet long and 13.5 feet wide at its widest point. It has an operational lifetime of at least 15 years. Its solar arrays and six nickel-cadmium batteries can provide an average of 3 kilowatts of electrical power. Using the Russian Kurs system, the Zarya will perform an automated and remotely piloted rendezvous and docking with the Service Module in orbit. Its docking power will accommodate Russian Soyuz piloted spacecraft and unpiloted Progress resupply spacecraft. Each of the two solar arrays is 35 feet long and 11 feet wide. The module’s 16 fuel tanks combined can hold more than 6 tons of propellant. The attitude control system for the module includes 24 large steering jets and 12 small steering jets.

... there is a need for a less expensive but equally durable control and "burnable poison" rod "spider" that will not obstruct fuel rod inspection, but will expose the individual rods for examination without imposing a need to dismantle the entire fuel assembly. There is, of course, a further need for a more flexible control and "burnable poison" rod assembly that will permit optimum fuel element relocation with the reactor core without requiring specific modifications or producing undesirable thermal effects.  3, record 53, English, - burnable%20poison%20rod%20assembly

A primary control system operates each primary control rod assembly to maintain reactor criticality by adjusting the quantity of neutron absorber or poison material(typically boron carbide) in the active core region and to effectuate shutdown in normal and abnormal operations. Typically, the absorber material(often contained in rod bundles) of each primary control assembly is reciprocated vertically within the core between several adjacent fuel assemblies to control reactivity.  1, record 54, English, - neutron%20absorber%20rod%20bundle

Les détecteurs mobiles sont du type chambres à fission. Ce type de capteur neutronique est une chambre d'ionisation classique et utilise comme matière sensible aux neutrons, l'uranium. Celui-ci, enrichi à 90 % en uranium 235, est déposé sous forme d'une couche d'oxyde. Chaque détecteur [...] est constitué d'une électrode centrale (anode), d'une deuxième électrode (cathode) qui détermine le volume de mesure, et d'une enveloppe de protection externe.
