{{#Wiki_filter:f: , 4.0 ' SITE AND DESIGN FEATURES. 4.1 Site l~ The reactor'and associated equipment 'is housed in the Washburn Laboratories L . located between West Street and Boynton Street on the campus of Worcester
. Polytechnic Institute in Worcester, Massachusetts.- .
i 4.2 Restricted Area and Exclusion Area The reactor room shall constitute a restricted area as defined in 10 CFR 20 and shall be controlled' by partition's and normally locked doors, in addition, two small areas, one each on the second and third floors of Washburn Laboratories, directly above the reactor control drives, shall
.become. restricted areas whenever the reactor is operating at power levels in excess in 1 kW and radiation levels in any of the rooms exceed those !
specified in 10 CFR 20.105. The exclusion areas, as defined in 10'CFR 100, shall consist of the reactor room and the areas above the reactor. ; 4.3 Reactor Building and Ventilation System The reactor shall be housed in a closed room that is designed to restrict i leakage. The ventilation system shall provide at least two changes of air per hour in the reactor room whenever the reactor is operating. 4.4 Reactor Core Fuel Elements: Standard fuel elements shall be flat plate type consisting of. uranium-aluminum alloy clad with aluminum. The width and depth of each. fuel element shall be 3 in. x 3 in. Each element shall have an active
. length of 24 in. There shall be a maximum of 18 g of U-235 in each fuel plate and not more than 140 g or U-235 in any fuel element. Standard fuel elements may be of two types: (1) with 10 fuel plates, each plate 0.099 in. thick including a clad thickness of 0.030 in.; (2) with 18 fuel plates, ,)
each' plate 0.060 in thick with a clad thickness of 0.015 in. on each side. A maximum of 27 standard fuel elements may be installed in the core. l Not more than two experimental fuel elements with eight removable fuel i plates similar to type (1) fuel plates and fitted with removable top end boxes may be installed in the core. These elements may be used as part of the core assembly either as complete elements or as partial assemblies, loaded with from 2 to a total of 10 fuel plates each. 4.5 Reactor Safety and Control Systems The safety system shall be designed so that no single electrical fault that partially or completely disables the automatic scram function can, in any manner, impair or disable the manual scram function, and vice versa. The safety system shall be fail safe with respect to loss of voltage. 8708200350 870810 8 PDR ADOCK050g4 P . l Worcester Tech Specs 1
