Examine the Fuel Size Effect on Nuclear Power Reactor Safety (Published)

The mass of fuel in the operating reactor could contribute to the safety of the reactor. To investigate the cooling problem of the fuel, safety margin test was conducted on design decay heat and design volume of the fuel in the reactor core. Linear Regression Analysis Techniques was applied on some typical Water-Cooled Reactor Design (WCRD) models. The results of the statistical analysis on these types of nuclear reactor models reveals that the WCRD models promises stability under application of small size of uranium (fuel) at 9g and below than large size of uranium (fuel) at 12g and above. Meanwhile, at 9g of fuel element the reactor seems to be most stable and safer as the regression plot was optimized. The safety margin prediction of 0.62% was validated for a typical WCRD model as an advantage over the current 5.1% challenging problem for plant engineers to predict the safety margin limit. The implication of this research effort to Nigeria’s nuclear power project is discussed

Investigating the Effect of Loss-Of-Pressure-Control on the Stability of Water-Cooled Reactor Design Models (Published)

To investigate loss-of-pressure-control on the stability of a typical water-cooled reactor design models during operation in terms of normal applicable pressure within reactor core and abnormal applicable pressure within reactor core. Linear Regression Analysis Techniques was applied on a typical water-cooled nuclear reactor design models, viz Water-Cooled Reactor Design with Normal Pressure (WCRD NP) flow rate within the reactor and Water-Cooled Reactor Design with Abnormal Pressure (WCRD AP) flow rate within the reactor. Empirical expressions are obtained for WCRD NP model and WCRD AP model. The results of the statistical analyses on these two types of nuclear reactor models reveals that the WCRD NP promises to be more stable than WCRD AP. The implication of this research effort to Nigeria’s nuclear power project is discussed
