検知することが必要不可欠である。It is essential to detect fires in the GB, which are used to safely handle nuclear fuel materials and prevent radioactive contamination of the work environment and the surrounding environment, in order to ensure the safety of facilities and workers. is there.
従来、火災の感知器には消防法で認定されている熱感
知式、煙感知式及び熱煙感知式がある。Conventionally, there are heat detectors, smoke detectors, and heat smoke detectors that are certified by the Fire Service Act.
熱感知式はある設定温度、例えば60℃以上における空
気の膨張、金属の膨張、金属の融解、或いは熱電対の熱
起電力等を利用する方式が採られている。The heat sensing method employs a method of utilizing expansion of air, expansion of metal, melting of metal, or thermoelectromotive force of a thermocouple at a certain set temperature, for example, 60 ° C. or higher.
また、煙感知式はラジウム等、密封された微量の放射

電極間のイオン電流の煙に含まれる微粒子の存在による
変化を利用する方式、或いは煙の微粒子に光が衝突し、
散乱した光をフォトセルで受けて信号を出す方式等が採
られている。The smoke sensing method uses a change in ion current between two electrodes facing each other in the air ionized with a small amount of sealed radioactive material such as radium due to the presence of fine particles contained in smoke. Or, light collides with smoke particles,
A method of receiving scattered light with a photocell and outputting a signal is adopted.
これらの火災感知器からの検知信号があると火災報知
器から火災警報が発せられるようになっている。When there is a detection signal from these fire detectors, a fire alarm is issued from the fire alarm.
しかしながら、従来の熱感知式のものは、ある設定温

ならず、ほこり、霧或いは蒸気等でも反応するが、GB内
では粉末状の核燃料物質を取り扱ったり、また酸蒸気の
発生等があるため、感知器がこれらに反応して誤って火
災警報を発してしまうことが考えられる。In addition, the smoke-sensing type reacts not only with fine particles due to smoke at the time of fire but also with dust, mist, steam, etc., but since GB powder is handled, and acid vapor is generated, etc. It is conceivable that the detector may accidentally give a fire alarm in response to these.
したがって、これらの感知器はGB内の温度監視、火災
の感知には不適当である。Therefore, these detectors are not suitable for temperature monitoring in GB and fire detection.
また、GB内の雰囲気特性はGB内での取扱物質、設置機
器によって異なるため、施設で使用する火災感知器を一
種類に統一することは困難である。Also, since the atmosphere characteristics inside the GB differ depending on the substances handled within the GB and the equipment installed, it is difficult to unify the fire detectors used in the facility into one type.

ガスが放出されるようになっている。In the figure, GB is made airtight by a stainless steel can body, a window plate, gloves and the like. Since the can body is made of stainless steel, if a fire occurs in the GB, it is the window plate and the glove that affect the airtightness of the GB. Normal,
An acrylic plate is used for the window plate, and the heat distortion temperature of the acrylic plate is 90 to 100 ° C as a catalog value and 95 to 105 ° C as an experimental value. The experimental temperature limit of neoprene gloves is about 180 ℃. The temperature sensor installed in the GB is composed of at least two types of sensors having different measurement principles, such as a platinum resistance temperature detector 1a and a thermocouple 1b. Then, the output of the temperature sensor is converted into a current value by the temperature converters 3 and 4 and taken into the computer 9 as temperature data, and is also input to the alarm setters 7 and 8. When the temperature exceeds the set temperature, the fire extinguishing equipment 12 is turned on. It is designed to work. Fire extinguishing equipment 12
Is composed of a halon control panel 12a, a starting gas cylinder 12b, and a halon cylinder 12c, and when a fire signal is input, the starting gas cylinder 12b is first actuated by the halon control board 12a,
This operation drives the halon cylinder to release halon gas into the GB.

）。The outputs from the two types of temperature sensors 1a and 1b are converted into current values (4 to 20 mA / 0 to 100 ° C.) by the temperature converters 3 and 4. Digitize the output current value of these temperature converters
It is taken into the temperature monitoring computer 9 in GB. Then, from at least one of the platinum resistance temperature detector 1a or the thermocouple 1b, for example,
When a current value of 6.4 mA corresponding to 40 ° C is input, the warning alarm 10 issues a warning warning to notify the operator of the abnormality (Fig. 2 ~). The set temperature at this time is to notify the temperature abnormality in the GB at an early stage, and is set to a value corresponding to the state where a fire has not yet been reached. The operator visually confirms the site with this warning alert, and when the cause is clarified, it is removed and the process ends (Fig. 2,

作業が行われることになる（第２図〜）。The outputs of the temperature converters 3 and 4 are input to the AND circuit 11 via the alarm setters 7 and 8, respectively. When the abnormal temperature condition in GB is not improved and the temperature further rises, for example, the set values of the alarm setters 7 and 8 are set to 60.
When both sensors detect the temperature, the GB fire alarm 6 is sounded, and at the same time, a GB fire signal is output to the halon control panel 12a of the halon fire extinguishing facility 12. The setting value of 60 ℃ is
It is a value set to be on the safer side based on the heat distortion temperature of the acrylic plate. Since the detection of the set value of 60 ℃ is detected by two types of sensors with different measurement principles, the probability of false detection is high. Is significantly reduced. And Halon control board 12a is G
B When a fire signal is input, a halon release signal is output to the starting gas cylinder 12b, and as a result, the halon cylinder 12c is activated to release halon gas into the GB and fire extinguishing work is performed. (Fig. 2-).
