Development And Implementation Of Post Graduate Nuclear Engineering Education In Nigeria

Nigeria has abundant energy resources that include natural gas, large hydro, coal, nuclear, small hydro, solar (PV and PT), and wind. However, the country\u27s per capita electricity consumption is lower than the African continent’s average. Therefore, there is a need for the diversification of the electricity supply in Nigeria. The government of the Federal Republic of Nigeria has acknowledged that nuclear energy would play a significant role in enhancing the per capita electricity generation. Consequently, the Nigeria Atomic Energy Commission (NAEC), as the national focal agency for developing and harnessing peaceful uses of nuclear energy in Nigeria, developed a strategic plan for the implementation of nuclear energy known as the National Nuclear Power Programme (NNPP). The NNPP plan was approved by the federal government of Nigeria in 2007. A critical component of the NNPP is the construction and operation of a nuclear power plant. Nuclear power plants are huge national engineering assets that require a plethora of human resources. In order to meet this need for knowledgeable and capable individuals, the NAEC, in partnership with four Nigerian universities, developed a curriculum for master’s programs in nuclear science and engineering. This paper discusses the master’s program in nuclear engineering that was implemented at the University of Port Harcourt. The program lasts for 15 months and consists of 20 core courses, 4 electives, and one research project. To date, 13 students have graduated from the master’s program and acquired the necessary competencies with three of these graduates already enrolled in PhD programs for nuclear engineering outside Nigeria. In addition, nine papers have been published in international journals from the research work carried out by these student

Prediction of Pressure Drop in Subsea Pipeline Using Pipesim Software

The number of offshore developments for which long-distance tie-back is usually implemented has increased recently, leading to increasing pressure loss concerns from such systems. In the literature, it revealed that pressure drop in multi-phase transport is quite complex to compute manually. Hence the need for multi-phase flow simulation software. PIPESIM is a leading industry software currently used in the oil and gas industry for multiphase flow simulation. In this study, a 64km subsea pipeline system comprising two sections; 23km, 22.064in ID and 41km, 24inch ID, coated with 3mm (0.003m) polyethene insulation and transporting multiphase hydrocarbon fluid in an ultra-deep-water field was modelled in PIPESIM. Network simulation for the base case was carried out at 114barg (114MPa) inlet pressure and 18.7MMSCfd gas flowrate. The observed system pressure drop was dependent on pipeline inlet pressure, flowrates, and internal pipe diameter. 13.8barg (13.8MPa) was lost from the system for the base case simulation. Sensitivity analysis carried out using Gas volumetric flowrates of 3, 12 and 18.7 MMSCFd. The inlet pressures of 57, 114 and 171barg combined with six different pipe diameters generated a unique combination of 81 data points that were used in the development of a pressure drop correlation using the LINEST regression analysis tool in Microsoft Excel. At high flowrate and high inlet pressure, the pressure-drop observed was minimal and vice versa. Also, at constant flowrates and inlet pressures, the pressure drop was observed to increase with increasing pipe sizes. An R2 value of 0.9226 was obtained from the analysis. The plot of Predicted Pressure-drop against Calculated pressure-drop similarly gave an R2 value of 0.8025. Both results showed usefully, and hence the developed correlation can be used as an estimate in the absence of PIPESIM software for pressure drop prediction purposes.

Industrialization of Fermented Food Processes: How Far in Nigeria?

837-843Studies on selected fermented foods, indigenous to Nigeria, viz. ogi, gari, fufu, lafun, iru, ogiri, ugba and okpeye, are reviewed. A brief description about their production process is presented. The evaluation about their commercialisation is given. It is observed that only iru, ogi and gari have been commercialised to some extent, the other products are still made as a traditional family art. Efforts made so far towards identifying the microorganisms implicated and the biochemical changes that occur, are described. It is pointed out that areas such as development of appropriate starter cultures, effect of process variables and scale-up strategies need further investigations
