ARMY GAS-COOLED REACTOR SYSTEMS PROGRAM. PRELIMINARY HAZARDS SUMMARY REPORT FOR THE ML-1 NUCLEAR POWER PLANT

Technical Report · Wed Apr 22 04:00:00 EST 1959

OSTI ID:4212974

The ML-1 (mobile, low power) nuclear power plant is described with particular emphasis on the neutronic characteristics, the control and instrumentation system, equipment description and plant safety considerations. The site is described with reference to geology, mate, and population density. Hazards which would sult from both normal and abnormal operation are alyzed in detail with emphasis given to possible exursions and to the distribution of any resultant radioctive products. The hazards described include those rising from power plant operation at the ML-1 site and those involving transport of the shutdown reactor to other sites within NRTS for maintenance. It is concluded that a condition which would be hazardous to the surrounding area could only resuli from gross physical changes in the reactor core. The maximum credible accident would produce such a change and could only result from a catastrophic failure of the gas piping coupled with the unlikely procedural error of having clear water, rather than borated water, in the operating neutron shield.
