Generalized configuration of a fiber-optic communication system Information Input The information input may be in any of the several physical forms, e. Therefore an input transducer is required for converting the non-electrical input into an electrical input. For example, a microphone converts a sound signal into an electrical current, a video camera converts an image into an electric current or voltage, and so on. In situations where the fiber-optic link forms a part of a larger system, the information input is normally in electrical form. Examples of this type include data transfer between different computers or that between different parts of the same computer. In either case, the information input must be in the electrical form for onward transmission through the fiber-optic link. The modulation of an optical carrier may be achieved by employing either an analog or a digital signal. An analog signal varies continuously and reproduces the form of the original information input, whereas digital modulation involves obtaining information in the discrete form. In the latter, the signal is either on or off, with the on state representing a digital 1 and the off state representing a digital 0. These are called binary digits or bits of the digital system. The number of bits per second bps transmitted is called the data rate. If the information input is in the analog form, it may be obtained in the digital form by employing an analog-to-digital converter. Analog modulation is much simpler to implement but requires higher signal-tonoise ratio at the receiver end as compared to digital modulation. Further, the linearity needed for analog modulation is not always provided by the optical source, particularly at high modulation frequencies.

Therefore, cooling and shielding are required for spent fuel.

After nuclear fuel is unloaded from the reactor, it is stored in a spent fuel pool SFP to prevent criticality accidents. The depth of the typical SFP is about 12 m and the height of the storage rack is about 4 m.

There is about 8 m of water above the top of the storage racks to provide substantial radiation shielding and cooling even when a spent fuel assembly is being moved above the rack [ 1 ]. In the SFP, the water level is maintained at more than 7 m above the top of the spent fuel. As mentioned above, the spent fuel should be cooled to prevent heat-up to high temperatures from radioactive decay because it still continues to produce decay heat.

Therefore, reliable real-time monitoring is essential to measure safety related parameters, such as temperature and water level, inside the SFP [ 3 , 4 ]. Conventionally, thermocouples and resistance temperature detectors RTDs are used to measure the temperature of the water and coolant in nuclear facilities, including the SFP, vessel, and piping.

In the case of the water level inside the SFP, it is normally measured by using an ultrasonic water level meter.

However, there are difficulties in measuring temperature and water level using existing electronic sensors due to their limit of measurable distance, and high electromagnetic interference EMI or radiofrequency interference RFI.

In addition, the conventional sensors installed in nuclear facilities cannot operate when it is not possible to closely access the SFP during a loss of power accident because they usually require an alternating current AC power supply. Arashizil Sponsored products related to this item.
