Integrating the Safety Evaluation for a Molten Salt Reactor Operation and Fuel Cycle Facility Application

Assessment of Adequacy and Completeness of Standards Endorsed by Regulatory Guides to Molten Salt Reactors

“…Salt-fueled MSR facilities are significantly different from previously licensed nuclear fuel and reactor facilities. Salt-fueled reactors are further subdivided into thermal-spectrum and fast-spectrum designs [9]. The types of radiological systems and locations of fissile material vary significantly by MSR concept.…”

“…Different designs are currently under development to achieve different performance objectives [11]. For example, some designs focus on consuming the actinides in spent LWR fuel to reduce long-term radiotoxicity, whereas others seek to implement a modernized version of the MSRE technology to minimize their development risks [9].…”

“…Molten salts are an attractive medium for heat transfer as compared to other heat transfer mediums, such as water, liquid metal, or gas [9]. Fluoride and chloride salts have been demonstrated to be very stable thermodynamically with no radiolytic decomposition in the liquid phase.…”

“…In summary, there are a number of key aspects that differentiate an MSR design from traditional LWR designs [9]:…”

Density Measurements of Molten LiF–BeF2 and LiF–BeF2–LaF3 Salt Mixtures by Neutron Radiography

“…19,20 The temperatures of interest in MSRs span from the FLiBe salt's freezing point (732.2 K 21 ) to temperatures approaching 1,100 K. FLiBe systems are commonly designed to operate at 900 K to 1,000 K. The highest temperatures may be encountered during off-normal conditions. 22 There are several complications for measuring the temperature-dependent solubility of species in molten halide salts. First, salts must be handled under inert conditions because they readily absorb oxygen and moisture.…”
