حول قسم الهندسة النووية

تم إنشاء قسم الهندسة النووية كأحد أقسام كلية الهندسة عام 1974م وتم قبول أول دفعة في العام الدراسي 1977م كما شهد عام 1981م تخريج أول دفعة. ويهدف قسم الهندسة النووية وهو القسم الوحيد بالجامعات الليبية إلى إعداد الكفاءات العلمية المؤهلة والقادرة على استيعاب التطورات التي تحدث في مجال العلوم النووية المساهمة في إدخال أساليب التقنية النووية وتطويعها للاستخدامات السلمية في كافة المجالات ذات العلاقة.

شعب القسم: يضم القسم حالياً شعبتين هما:  شعبة الطاقة وتهتم باستخدامات المفاعلات النووية. وشعبة التطبيقات الإشعاعية وتهتم بتطبيقات الإشعاع النووي .

Evaluation of vertebral fracture assessment images for the detection of abdominal aortic calcification

Dual-energy x-ray absorptiometry (DXA) is an established modality for the assessment of bone mineral density. DXA has also been used for the detection of abdominal aortic calcification (AAC) using lateral images taken for vertebral fracture assessment (VFA). In this phantom study, the capability of VFA for the detection of AAC was investigated. A Perspex phantom of variable width in the range 15-30 cm was used to simulate abdominal soft tissue. Aluminium strips of thickness 0.05-2.0 mm were sandwiched between two halves of the phantom to mimic aortic calcification. VFA images of the phantom were acquired in single-energy mode and analysed by placing regions of interest over the aluminium strip and an adjacent area of Perspex. For each phantom width, the minimum detectable aluminium thickness was assessed visually and related to contrast-to-noise ratio (CNR). Linearity of pixel value with aluminium thickness was tested by linear regression and correlation. Repeatability was measured with five repeated scans for selected phantom configurations. The minimum thickness of aluminium that could be visualised increased with phantom width and varied from 0.05 mm at 15 cm Perspex to 0.5 mm at 30 cm Perspex; the CNR threshold was about 0.03. At all phantom widths, the variation of pixel value with aluminium thickness was strongly linear (r²>0.98, p

RTC-method for the control of nuclear reactor power

In this paper, a new concept of the Reactivity Trace Curve (RTC) for reactor power control is presented. The concept is demonstrated for a reactor model with one group of delayed neutrons, where the reactivity trace curve is simply a closed form exponential solution of the RTC-differential equation identifier. An extended reactor model of multigroup (six groups) of delayed neutrons is discussed for power control using the RTC-method which is based on numerical solution of the governing equation for the RTC-differential equation identifier. In this numerical solution, an impeded analytical solution for the RTC-identifier in every sampling time step is used. Finally, the concept is applied to a more rigorous reactor model, namely; a model of multigroup of delayed neutrons with temperature feedback. The simulation studies for all of the above mentioned cases demonstrate the validity of the concept for reactor power control with absolute elimination of power shootings.

Assessment of Image Quality Parameters for Computed Tomography in Tripoli, Libya

Computed tomography (CT) is a powerful imaging technique widely used. In Libya, the performed CT examinations are increasing, and the high doses associated with those CT examinations must be controlled. The aim of this study is to investigate the performance of several CT scanners image quality used in different medical clinics in Tripoli.Philips CT phantom (Serial Number: 4535-671-35962) was used to acquire images, under the same imaging parameters (120 kVp, 200 mAs, image size of (512 x 512) by implementing the IAEA standards for image quality control (QC). Images were obtained in the DICOM format from each CT.Results showed that there was no major difference in uniformity between the selected regions of interest ROIs in X and Y- directions within all obtained scans, with the coefficient of variation %CV varying between 0.330 and 0.528. The linearity test of all scans exhibited the same trend as it was provided by the phantom manual; the lowest mean pixel intensity value was 956.678 for polyethylene and the highest mean pixel intensity value was for Teflon 1945.347. The contrast C and CNR, between the water layer and Teflon was the highest value varied between 172.913 and 262.199, and the lowest value, varied between 0.844 to 19.015.
