Abstract

This research was approved optical fiber bending sensors with good characterization and variations in the concentration of ammonia solution. This research uses experimental methods in the laboratory. The technique was done by stripping multimode optical fibers (cladding measuring 125 ?m and core 62 ?m) which is exfoliated cladding then replaced by polydimethylsiloxane (PDMS) and bending with the combustion process. The concentration of ammonia solution used in this research varies from 1-10%. Measurement of fiber optic sensors using optical power meter (OPM) with a wavelength of 1310 nm and 1550 nm, and light source (LS) at a frequency of 0 Hz, 270 Hz, 1000 Hz, and 2000 Hz. The result showed that ammonia solution caused instability in light intensity. However, the higher the frequency of light. The lower of the intensity with the difference in intensity produced is very small.Keywords: ammonia, bending, cladding, optical fiber, polydimethylsiloxane (PDMS).

Abstract

The calculation of fission and capture reaction rate with and without filter has been done using REACT of SRAC. In material 1 fission reaction rate with and without filter were increased by increasing percent of U233. The highest fission reaction rate with filter was 5,7194x10-2reaction/cm3sand without filter was 6,1361x10-2 reaction/cm3s. Meanwhile capture reaction rate with and without filter were decreased by increasing percent of U233. The highest capture reaction rate with filter was 2,2156x10-2 reaction/cm3s and without filter was 2,4906x10-2 reaction/cm3s. In material 3, fission and capture reaction rate with and without filter were decreased by increasing percent of U233 in material 1. The highest fission reaction rate with filter was 1,5218x10-2 reaction/cm3s and without filter was 1,6293x10-2reaction/cm3s. The highest capture reaction rate with filter was 2,2156x10-2 reaction/cm3s and without filter was 2,3993x10-2reaction /cm3s. Neutron reaction rate with filter was smaller than neutron reaction rate without filter

Abstract

The calculation of fission reaction rate and capture reaction with and without filters have been done using the REACT of SRAC. The calculation of fission rate on fuel 1 and 2 were 5,39 x 10-2 reaction/cm3s with filter and 6,35 x 10-2 reaction/cm3s without filter, then of capture reaction rate with filter on fuel 1 and 2 were 2,91 x 10-2 reaction/cm3s, without filter on fuel 1 was 3,9 x 10-2reaction/cm3s and fuel 2 was 3,78 x 10-2 reaction/cm3s. The calculation of capture reaction on cladding with filter was higher than without filter was 2,15 x 10-3 reaction/cm3s, on moderator with filter was lower than without filter was 3,18 x 10-3 reaction/cm3s. The highest neutron spectrum with 1% enrichment of experiment 1 in thermal energy was 6,31 x 10-6 MeV-1 and in fast energy was 6,44 x 10-6 MeV-1, and decreased constantly. Meanwhile of experiment 2, neutron spectrum in thermal energy was 1,37 x 10-5 MeV-1 and in fast energy was 6,91 x 10-6 MeV-1, and decreased significantly from 1% to 2% enrichment then decreases constantly until 5% enrichment
