In this paper, a fiber Bragg grating (FBG) pressure sensor was designed and fabricated using 3D printing method for the measurement of vertical pressure. The raw material used for the fabrication of this new pressure sensor was Polylactic Acid (PLA). The effectiveness of embedding FBG sensors inside printed PLA material was first examined taking into account different infill densities. It is found that the FBG sensor can be successfully embedded into PLA material without sacrificing its sensing performance. The change of infill density has no influence on both peak and residual wavelength change of FBG sensors during and after the printing process. All FBG sensors printed inside PLA prototype with different infill density values exhibit almost the same peak and residual wavelength rise values in the printing process. In addition, the higher the density value, the longer the time required to finish printing process. A simple FBG pressure sensor was designed and fabricated according to the successful experience of embedding FBG sensors into printed PLA. Measurement performance of this FBG pressure sensor was examined in laboratory cyclic loading tests. Calibration tests indicate that the maximum measured vertical pressure of this new pressure sensor was 2000 kPa with a measurement sensitivity of 13.22 kPa/pm. INDEX TERMS Fiber Bragg grating, 3D printing, polylactic acid, vertical pressure, encapsulation method.

“…FBGs have been used to measure pressure between 0 to 70 MPa (Mihailov 2012), which is a useful range for AdvSMRs. The wavelength-pressure relationship is also linear across this range, which makes calibration much easier (Shen et al 2007). As shown in Figure 6.2, an increase in radial pressure on a fiber will cause compression.…”

Energy Research and Development Roadmap and industry stakeholders by evaluating optically based instrumentation and control (I&C) concepts for advanced small modular reactor (AdvSMR) applications. These advanced designs will require innovative thinking in terms of engineering approaches, materials integration, and I&C concepts to realize their eventual viability and deployment. The primary goals of this report include:1. Establish preliminary I&C needs, performance requirements, and possible gaps for AdvSMR designs based on best-available published design data.2. Document commercial off-the-shelf (COTS) optical sensors, components, and materials in terms of their technical readiness to support essential AdvSMR in-vessel I&C systems.3. Identify technology gaps by comparing the in-vessel monitoring requirements and environmental constraints to COTS optical sensor and materials performance specifications.4. Outline a future research, development, and demonstration (RD&D) program plan that addresses these gaps and develops optical-based I&C systems that enhance the viability of future AdvSMR designs.The DOE-NE roadmap outlines RD&D activities intended to overcome technical barriers that currently limit advances in nuclear energy. As part of this strategy, DOE-NE is sponsoring research on advanced reactor supportive technologies to reduce the identified barriers. Key challenges that must be overcome include the high capital costs to develop nuclear power plants, maintaining safety performance as the reactor fleet expands, minimizing nuclear waste, and maintaining strong proliferation resistance. AdvSMR designs are a major component of this strategy, because these designs offer a number of unique advantages. The modular and small size of AdvSMR designs naturally lead to reduced capital investments and, potentially, construction savings through factory fabrication. However, new economic and technical challenges accompany the many attractive features offered by AdvSMR designs. Specifically, the modest power output of AdvSMRs does not provide the economy of scale afforded by large reactors. In addition, many of the AdvSMR designs operate at much higher temperatures than lightwater reactors and require instrumentation to withstand harsh, in-vessel environments arising from unconventional, chemically aggressive coolants and unique reactor system configurations.Addressing these I&C challenges will be critically important to the AdvSMR development program to ensure the viability and future success of advanced reactor designs. Solutions will likely be found through evolution of conventional reactor technology, and the development of entirely new concepts. Early pressure/boiling water reactors used conventional I&C technologies (e.g., thermocouples, ionchambers, strain-gauge pressure sensors) to satisfy design requirements. Because these technologies worked well in the relatively low-temperature reactor designs, the demand for alternate I&C technologies was limited. At the time, optical-based reactor monitoring concepts were g...

In this paper, we have proposed and demonstrated a simple fiber-optic temperature sensor based on the bending loss of a TEC(thermally expended core) fiber attached to a bi-metal. The deformation of the bi-metal caused by the change in its temperature induces the bending loss of the TEC fiber. The experimental result shows that the temperature sensitivity and operation temperature range of the device are controllable through the adjustment of the structure of the expanded core fiber. The fabrication procedure of the device is described in detail.
