[en] On 2nd Apr. 2011, highly contaminated water which flowed into the cable trench of unit 2 brought ambient dose rate up to 1,000mSv/h at the cable pit near the sea water intake of the unit. This was the first sign of the leakage of contaminated water

[en] The measured sensitivity of the cavity was evaluated and it is full consistent with the measured values. It was explored that the tuning system (the fog structure) has a significant contribution to the cavity sensitivity. By using ribs or by modifying the rigidity of the fog we may reduce the HWR sensitivity. During cool down and warming up we have to analyze the stresses on the HWR to avoid plastic deformation to the HWR since the Niobium yield is an order of magnitude lower in room temperature

[en] The file contains the presentations of the 27 annual conference of the nuclear societies in Israel. The subjects of the conference are: aspects of nuclear energy and nuclear technology, applications of radioisotopes and radiation, radiation measurements, issues in radiation protection and radiation in medicine, the consequences of the Fukushima accident. During the conference awards will be given for outstanding student works

[en] The faculty members in the Nuclear and Radiation Engineering Program have made significant contributions to the placing of PhD and MS students in various programs at the national laboratories and US government. The success and foundation of the program is based on a strong collaboration with staff members at these various laboratories, per-reviewed publications, and continued financial support

[en] Rotem Industries is one of the partners in the JHR project .The Project deals with research reactor facilities. To train future employees for recruitment, The Company supports and assists students in undergraduate and master's degrees. This work is part of an MSc thesis accompanied by Rotem Industries instructors

[en] The gamma spectrum of a 252Cf neutron source holds a large number of peaks from the FP, their products and other Cf isotopes present in the spectrum. The differences between a new and an old 252Cf neutron source gamma spectrum are mainly in the size of 661, 388 and 177 keV peaks from 137Cs, 249Cf and 251Cf, respectively

[en] The article presents a preliminary risk analysis of the main features in NPP (Nuclear Power Plant) that includes SMR - Small and Modular Reactors, given an extreme threat scenario. A review of the structure and systems of the SMR is followed by systematic definitions and analysis of the threat scenario to which a preliminary risk analysis was carried out. The article outlines the basic events caused by the referred threat scenario, which had led to possible failure mechanisms according to FTA (Fault-Tree-Analysis),critical protective circuits, and todetecting critical topics for the protection and safety of the reactor

[en] The LORELEI (Light-Water One-Rod Equipment for LOCA Experimental Investigation) test device is dedicated for the study of fuel during a Loss of Coolant Accident (LOCA). The safety of this project is been done with a collaboration between the Israeli and the French teams and will have to be authorized by the French regulation authority (ASN). The main challenges in safety are: 1. Preparing a safety reports according to the French regulations and standards. 2. Learning and obtaining knowledge on the safety philosophy of experimental devices in French

[en] Activity deposition pattern of outdoor explosive RDD experiments were discussed and analyzed. In cases of fine, respirable size, aerosols dispersion, most of the activity deposited inside a circle of up to 4 fireball radii around the detonation point. About an order of magnitude less was deposited in the rest of the wide open area, in the downwind direction. The effects of different RA particles size distribution on the ground deposition pattern is still being studying under the framework of GF project

[en] The major x-ray procedures that expose the medical staff at hospitals are angiography and heart catheterization. Most of those procedures take place while the medical staff is standing to the right side of the patient (the patient is lying on his back). It is possible to change some of those examinations and make those invasive procedures on the left side of the patient instead of the right side of his body
