(5 Marks) Question 2: Briefly explain the term plant availability in nuclear technology. Consider a nuclear power plant with an output rating of 1000MW_(e) . During a one- year period of operation , the plant delivers 200 .000 MWd of electric power to the utility grid. During this time the plant was down as follows: 30 days for refueling; 50 days for maintenance and repairs. Calculate the plant capacity and plant availability during the year.

Plant availability in refers to the percentage of time that a nuclear power plant is operational and capable of producing electricity. It is a measure of the plant's reliability and efficiency in delivering power to the grid.To calculate the plant capacity and plant availability during the year, we need to consider the total number of days in a year and the number of days the plant was down for refueling and maintenance.Plant capacity is the maximum power output that a achieve under ideal conditions. In this case, the plant has an output rating of 1000 MW_e.Plant availability is calculated by dividing the number of days the plant was operational by the total number of days in a year, and then multiplying by 100 to get the percentage.In this case, the plant was down for 30 days for refueling and 50 days for maintenance, totaling 80 days of downtime. The total number of days in a year is 365.Plant availability = (Number of operational days / Total number of days) * 100= (365 - 80) / 365 * 100= 285 / 365 * 100= 78.08%Therefore, the plant capacity is 1000 MW_e, and the plant availability during the year is 78.08%.
