A nuclear instrumentation system includes a source range channel, an intermediate range channel, and a power range channel. Each channel includes one detector installed around the pressure vessel. The detectors of the power range channel and the intermediate range channel both include several fission chambers. The detectors of the intermediate range channel and power range channel share several fission chambers. Since some detectors employ fission chambers, the Gamma radiation resistance property, anti-noise property, and anti-electromagnetic interference property are improved. Sharing fission chambers reduces the number of detectors to be installed, thus relieving the installation workload and the positioning of a follow-up detector. Further, the system increases the number of some channels, which increases redundancy and improves system reliability.

An enhanced digital light processing-based mask projection stereolithography method and apparatus are disclosed, where the apparatus comprises: a control platform capable of slicing a model of a to-be-prototyped object into layers, converting the layer into a bitmap, and further dividing the layer into a main body area and boundary filling areas; a digital light processing unit that is controlled by the control platform and capable of emitting a first light beam used for the corresponding main body area of the layer of the to-be-prototyped object; and a laser marking unit that is controlled by the control platform and capable of emitting a second light beam used for the corresponding boundary filling areas of the layer of the to-be-prototyped object. The present invention can not only implement high-speed prototyping but also avoid an edge distortion, thereby improving precision of object prototyping.
