It is widely known that frequent contact and exposure to radiation are hazardous to human health and detrimental to the equipment. Therefore, many radiation shielding applications have been installed to protect people and the working facilities from the harmful rays as well as to comply with work-safety regulatory requirements.For a long time, lead has been the leading material used in radiation shielding structures and applications. However, lead has come under severe criticism in recent years due to its disastrous impacts on people and the environment. Research shows that lead can negatively impact human’s nervous and reproductive system, weakening the muscles and damaging the brain. Therefore, the need for lead replacement and lead substitute materials is highlighted when selecting radiation shielding materials.

Tungsten as the new material is being developed to serve as lead replacement material that is100% lead equivalent in radiation shielding efficacy. Tungsten, which is a hard and rare metal and often exists in the form of chemical compound, serves as an efficient lead replacement material. Tungsten alloys have high density and hardness, in fact almost 60 percent higher than lead, which are desirable characteristics for radiation shielding applications. They can be used to mitigate X-ray and gamma rays. Other benefits of tungsten-based materials include their high temperature resistance and environmental friendly.

Three Mile Island and Fukushima have both demonstrated accident situations where the pressure and temperature inside the reactor were unknown to operators. Conventional pressure sensors and conventional temperature sensors fail when exposed to those harsh conditions, which include high pressure, temperature, and radiation. That lack of information regarding internal state can negatively affect how an accident is handled. In order to prevent any future accidents from ever reaching a similar severity, a new self-powered wireless dual-mode sensor with a composite tungsten-boron-carbide material had been produced.

Temperature and pressure sensors are vital pieces of monitoring equipment in a nuclear reactor, especially during accident conditions where temperatures and pressures can reach 1400 degrees Celsius and 10,000 PSI respectively. Unfortunately, conventional sensors cannot operate under the high temperatures, pressures and radiation conditions that occur during an accident. By choosing to work with a composite tungsten-boron-carbide material, harmful neutron and gamma ray radiation would be effectively attenuated for the langasite sensor to operate under normal operating conditions as well as extreme accident conditions. The maximum neutron fluence was determined using a TRIM simulation which was the basis for the decision of optimal material composition and thickness of the shielding, which was determined using MCNP simulations.

The shielding material for the system were chosen as composite of tungsten-boron-carbide to effectively shield neutron and gamma radiation. The design of the radiation shield is cylindrical as shown in the figure. Appropriate thickness and the material composition of the shielding material are determined through MCNP simulation. This radiation shield enables the sensor to be functional for five years inside the core.
