N2  - The key parameter in radio-isotopes production in research reactors is the neutron  flux. Also the long/short term plans for operation basically designed according to economical balance between utilization and cost, which made the key parameter in  this balance is the consumption rate. On the other hand, the safety operation limits and condition should be satisfied in all cases. In this study searching procedures for  the optimum core of Pakistan Research Reactor 1 (PARR-1) that provide neutron  flux suitable for isotopes production is investigated. All cores proposed are based  on the configuration of the first equilibrium core of (PARR-1). The objectives of  this optimization process is to maximize the neutron flux or minimizing the consumption rate, under the constraints of the maximum discharge burnup and the maximum power peaking factor limitations. To reach the desired objectives three modifications are examined; change of the fuel density, change of the reflector configuration and change of the fuel shuffling strategy. The results show that, by  increasing fuel density neutron flux decreased in the in-core irradiation positions, while by changing the reflector configuration the neutron flux increased in in-core irradiation positions, and by modifying the fuel shuffling strategy neutron flux is not  clearly changed but the fuel burnup and power density distribution be better than the  original one from the safety point of view
