Checking the Integrity of CCTV Footage in Real Time at Nuclear Facilities
Authors: Bobok I. , Kobozeva A. , Maksymov M. , Maksymova O. 
Published: February 2019

Video surveillance has become an important constituent part of the integrated security system of nuclear power plants. Due to this, the integrity and authenticity of the video transmitted by the surveillance camera are extremely important, and so is the possibility to identify violations of these categories of information in real time.
The authors propose a new method to detect one way of violating the integrity of the video sequence — “camera loop” hijacking. The proposed method based on identifying the perturbation in matrix of the current frame of the original video sequence in transition to the next frame ensures the efficiency of the method that is not dependent on the specifics and characteristics of the analyzed video sequence. The high efficiency of the method is confirmed by results of a computational experiment, under which type I and type II errors were not found. The practical value of the proposed method is the possibility of its work in real time because it is a polynomial of degree 1, as well as the simplicity and multiplatform implementation.

Authors: Pogosov O. , Derevianko O. 
Published: February 2019

The paper focuses on the fact that nuclear failures and incidents can lead to radioactive contamination of NPP premises. Nuclear and radiation hazard may be caused by malefactors in technological processes when applying computers or inadequate control in case of insufficient level of information security.
The researchers performed analysis of factors for reducing risks of nuclear and radiation accidents at NPPs considering specific conditions related to information security of NPP physical protection systems. The paper considers connection of heterogeneous factors that may increase the risk of NPP accidents, possibilities and ways to improve adequate modelling of security of information with limited access directly related to the functioning of automated set of engineering and technical means for NPP physical protection. Within the overall Hutchinson formalization, it is proposed to include additional functional dependencies on indicators specific for NPPs into analysis algorithms.

Authors: Gerliga V. , Kravchenko V. , Prityka I. , Ghanem Hussam 
Published: February 2019

The paper presents the technology of industrial waste purification based on the use of natural mineral bentonite sorbent with a large specific surface area, achieved by a cavitation crushing method, partially up to nanosize particles. The possibility for the purification of liquid radioactive waste (LRW) is shown by the example of floor drains with a significant content of salts, as well as organic mineral oils and surface-active substances. In addition to sorption of radionuclides, the used nanostructured sorbent has the ability to sorb heavy metals, salts, borates.
The proposed technology contains several stages: ultrasonic treatment of ozonized LRW with the addition of sorbent; centrifugation or precipitation of the resulting mixture; obtaining a sorption-crystalline precipitate and condensate by evaporation. The final stage of processing — evaporation and vitrification in detail in this paper are not considered.
The research presents the method of purification of actual LRW solutions for subsequent treatment with sorption-crystalline concentrate for vitrification. Coefficient of activity decrease equals to 103. The cost of technology is negligible, because it is based on the use of cheap bentonite. The proposed method can be used also for cleaning general industrial waste.
Distribution of gaps between fuel assemblies in the VVER 1000 core
Authors: Abdullayev A.M. , Zhukov A.I. , Maryokhin S.V. , Riabchykov S.D. 
Published: February 2019

The safety of fuel loading of VVER reactors is justified by calculations of the neutronic characteristics of the forthcoming campaign. These calculations are based on the design parameters of fuel assemblies (FA) — fuel enrichment, materials, design features, etc. However, during operation, some parameters change in an uncontrolled manner. In particular, FA can deform — bend or twist, this leads to the appearance of increased gaps between the fuel assemblies. These regions filled with a moderator lead to an increase in comparison with the calculations for the generation of thermal neutrons and, as a result, to a surge in the power of the fuel rods surrounding these regions. Safety requirements limit the power of fuel rods. Therefore, design capacities are increased by means of the so-called engineering margin factor to account for random outbursts. The deviation of the size of the water gaps between the fuel assemblies from the design ones should be known to calculate this coefficient, for example, the size distribution function of the gaps. This information is most often obtained by modeling the mechanical state of fuel assemblies in the reactor core. Other approaches are based on experimental data. Measurements in the core during the campaign are not possible. Therefore, the geometric parameters of the fuel assembly after the discharging from the core are measured. The presented paper uses the data of such measurements obtained after the 24th fuel campaign of ZNPP unit 4.
It is assumed that the fuel assemblies tend to retain the form they have in the “free” state, and mechanical interaction with neighboring fuel assemblies leads to a certain equilibrium state that can be easily analyzed. In contrast to similar calculations, the elastic energy functional of interacting fuel assemblies is proposed whose minimum gives the required size distribution function of the gaps. 24 and 25 campaigns were modelled; the role of inter-sector FA shuffling was studied.
The distribution of the gaps between the fuel assemblies in VVER-1000 core is calculated based on the measured deformations of the fuel assemblies discharged from the core and the elastic characteristics of the fuel assemblies. It was demonstrated that 95 % of gaps in the cores both with FA-A and FA-WR do not exceed 7.6 mm. The results can be used to calculate the engineering margin factor in determining the peaking factors of energy release.

Abstract: This research aims to determine differences in student anxiety levels based on gender and the relationship between students' anxiety levels before facing a mathematical test with achievement and then dig deeper information about the causes of anxiety in students. This research uses a mixed method with a sequential explanatory approach. The subjects of this study were students of class X MIA Kerinci Senior High School 2 totaling 100 students. The results of the research showed that students experiencing anxiety before taking a math test as the cause of anxiety is experience, intelligence, preparation, and family. Differences in levels of anxiety based on gender indicate that there is no significant difference between the level of anxiety experienced by male and female students but male students are more anxious than female students the cause is that there have been similar thoughts and goals in terms of achievement so as to make male students neither men nor women experience significant differences in anxiety levels. There is a relationship between the level of anxiety with learning outcomes of 0.43 which is in the category enough and has a positive relationship, namely the higher the level of anxiety, the higher the student learning outcomes. Descriptions of quantitative data indicate that there is no certainty for someone who has an anxiety level will get a definite value.

Background: Intravenous dexamethasone may produce perineal pruritus in some patients when administered as premedicant before induction of anesthesia.
Objectives of study: This randomized, double-blind study was done to evaluate the efficacy of pretreatment of lignocaine on the incidence and severity of dexamethasone-induced perineal pruritus.
Materials and methods: 100 patients were enrolled in this study and allocated randomly into two equal groups. Then, patients received intravenous medications in the following sequence before induction of anesthesia: in group I, injection lignocaine 1mg/kg diluted in 5 ml normal saline and in group II, 5 ml normal saline (placebo group), then one minute later, intravenous dexamethasone sodium phosphate 10 mg was given in all groups in 3 seconds and was observed the patient's response about perineal pruritus. The severity of perineal pruritus was graded based on the visual analog scale (VAS) as none (VAS 0), mild (VAS 1-3), moderate (VAS 4-6), or severe (VAS 7-10), and recorded the incidence and severity of perineal pruritus. Then general anesthesia was induced and continued as usual.
Results: In terms of demographic data, the results of this study showed that there was no significant difference between patients in both groups (P>0.05). Overall incidence and severity of perineal pruritus in lignocaine group was significantly less, when compared with placebo group (P<0.05).
Conclusion: It can be concluded that pretreatment with 1mg/kg intravenous lignocaine may effectively reduce the incidence and severity of dexamethasone induced perineal pruritus.

Authors: Naser Md Fazal , Rahman Mizanur , Khan Md Rokonuzzaman , Rahman Md Mostafizur , Hossain Md Muazzem 
Published: February 2019

Background: Retrocaval ureter also referred to as circumcaval ureter or preureteral venacava is a rare congenital anomaly with the ureters passing posterior to the inferior vena cava (IVC). The ureter classically course medially behind the inferior venacava winding around it and then passes laterally in front of it to then course distally to the bladder. Though it is a congenital anomaly, patients do not normally present with symptoms until the 3rd and 4th decades of life from a resulting hydronephrosis. This hydronephrosis may be due to kinking of the ureter. The ureteric segment is a dynamic or compression against the psoas muscle. It was initially considered as aberration in ureteric development; however current studies in embryology have led to it being considered as an aberration in the development of the inferior vena cava.
Objectives: The aim of our study was to explore the safety, feasibility and usefulness of retroperitoneoscopic surgery for retrocaval ureter performed in a single centre and to assess the short-term outcomes of patients treated with this surgical approach.
Materials and methods: Eight patients underwent retroperitoneoscopic transposition of ureter between March 2014 and November 2016, A 3-port, ballon-dissecting, retroperitoneal approach was used, no open conversion was required. Follow-up studies were performed with intravenous urography and ultrasonography.
Results: Mean operating time was 121 minutes (range 92-178) and mean anastomotic time was 56 minutes for all cases. Blood loss was minimum. None of the patients required blood transfusion. No intraoperative complications occurred. Hydronephrosis in all patients were decreased substantially after surgery.
Conclusion: Our results have demonstrated that retroperitoneoscopic transposition of ureter is an excellent minimally invasive treatment option for a retrocaval ureter that can be accomplished quickly and safely.
