This study has outlined the fiber bragg grating (FBG) temperature sensors signal processing
for data communications by using OptiGrating simulation software. The reflectivity of the …

Fiber Bragg grating (FBG) sensing is currently one of the leading measurement
technologies, but has made only minor inroads into nuclear diagnostics due, for the most …

This paper presents the novel results on fiber Bragg grating temperature sensor deployment
in high radiation and hazardous chemical environment of nuclear fuel recycle facility. The …

In-core temperature measurement is a critical issue for the safe operation of nuclear
reactors. Classical thermocouples require shielded connections and are known to drift under …

Wavelength-division multiplexed fiber-optic links could find applications in various radiation
environments. The space industry, for example, could benefit from radiation-tolerant high …

R2SUNED is a code system implementing the mesh-based Rigorous-two-step method for
shutdown dose rates calculations, making use of MCNP and ACAB codes. In addition to the …

In this paper we describe the main characteristics and experimental results, recorded in
more than four years of data acquisition, of a temperature and strain monitoring system …

In this work, we analyze the absorption spectra of silica fibers doped with erbium (Er) and
usual codoping atoms such as aluminum (Al) and germanium (Ge). This study is performed …

Fibre Bragg grating (FBG) temperature sensors have already shown short-term radiation
tolerance in nuclear environments. However, the effect of long-term irradiation needed to be …
