Design and construction of a system to measure rod drop time
Creators
Description
The measurement of rod drop time in any nuclear reactor is very important from nuclear safety point of view. This measurement should be carried out periodically once a week to be sure of the drop time value which is greater than orequal to 0.5 sec according to the safety report. Such a facility dose not exsist in the instrumentation and control system of the IRT-5000 reactor. The new system was designed and constructed in the control section it consists of: 1-An oscillator which generates 1 MHZ square wave., 2-Time base counter which devides the frequency by (10k) to introduce a clock with 100 HZ., 3-Display circuits which consist of five stages of synchronous decade counters, and five stages of BcD to 7 seg. decoder. Their outputs are connected to five stages of seven segment displays
