“…There are many reports available in literature based on reactivity insertion analysis of research reactors (Vertullo and Gimenez, 2003;Mirza et al, 1998;Nasir et al, 1999;Abou-El-Matty and Abdelhady, 2009) which are basically on calculation of reactor thermal hydraulic safety parameters from different points of view with different types and ranges of reactivity insertions. Most of these simulations were carried out so far by the use of PARET code.…”
