Authors: Kukhotskyi O. , Dybach O. , Iešmantas T.
Published: February 2019

Uncertainties are very important in risk analysis and should be considered in the decision-making process. This paper proposes the methodology for estimation of PSA uncertainties in risk-informed decision-making. The methodology allows solving the complex task of identifying the sources of uncertainties, assessing their range, and providing an approach for consideration of PSA results with uncertainties in combination with other factors underlying risk-informed decision-making. The levels of uncertainties are proposed to be classified using the variation factor. The authors applied the developed methodology to assess alternatives of post-Fukushima safety measures.
Analysis of criticality of melt during severe accidents in reactor vessel
Authors: Kovbasenko Yu. , Bilodid Yevgen
Published: February 2019

The article investigates the possibility of a self-sustaining chain nuclear fission reaction during the development of a severe accident in the core at nuclear power plants with reactors WWER-1000 of Ukraine. Some models for calculating a criticality at different stages of the severe accident in the reactor VVER-1000 vessel were developed and calculations of multiplication properties of fuel containing masses were performed.

The severe accident in the VVER-1000 core approximately divided into seven major stages: the intact reactor core, beginning of cladding damage (swelling), cladding melting and flowing down to the support grid, melting of constructional materials, homogenization of the materials at the bottom of the reactor vessel, stratification of corium at the bottom of the reactor vessel, the exit of the corium from the reactor shaft. It was shown that at the beginning of an accident, if fuel rods geometry is maintained, criticality might appear even if the emergency protection rods is triggered. With further development of the accident, the melt of fuel and structural materials will be deeply subcritical if water cannot penetrate into the pores or voids of the melt. In the case of the formation of pores or voids in the melt and the ingress of water into them, a recriticality may arise. A compensating measure is the addition of a boric acid solution to a cooling water with a certain concentration.

According to the results of the computation analysis, a reactor core loaded with TVSA fuel (Russian production) requires a higher concentration of boric acid in water to compensate the multiplication properties of the fuel system in emergency situations compared to the core loaded with TVS-WR fuel (manufactured by Westinghouse), i.e. TVS-WR fuel is safer from the criticality point of view.
A Data Scatter for a Shift of the Ductile to Brittle Transition Temperature for WWER-1000 Reactor Pressure Vessel Materials
Authors: Revka V.
Published: February 2019

In the most countries that operate the nuclear power plants with reactor pressure vessels a safety margin accounting a data scatter is applied for a conservative evaluation of a radiation shift of the ductile to brittle transition temperature for RPV metal. This scatter is to a significant extent due to material inhomogeneity and errors in determining the temperature shift and neutron fluence. In the regulatory practice of Ukraine, the obsolete approaches are used that can lead to an underestimation or overestimation of the transition temperature shift depending on the number of test data points.

In order to use the updated regulatory approaches that will be consistent with international practice, it is necessary to know the magnitude of the data scatter on the transition temperature shift which is characterized by a standard deviation. Therefore, the aim of the research work was to estimate the data scatter for WWER reactor pressure vessel materials using statistical methods.

The paper presents the results of a statistical analysis for a large array of surveillance test data for WWER-1000 reactor pressure vessels of NPP units which are operated in Ukraine. The data scatter for RPV base and weld metal has been estimated using a statistical treatment for the dependencies of a transition temperature shift, ΔTF, on the fast (Е > 0,5 MeV) neutron fluence. The ΔTF values have been derived from the Charpy impact tests. The Charpy V-notch specimens have been irradiated in the nuclear power reactors within a neutron fluence range of (3,0 ÷ 92,2)·1022 m-2 in the frame of a national surveillance program.

The analysis has shown the data scatter relative to the average regression line for RPV materials is characterized by a standard deviation of 5,5 °С. Based on the results obtained, it was suggested to use a double standard deviation of 11 °С as a safety margin to provide a conservative estimate for the radiation shift of the transition temperature of the WWER-1000 reactor pressure vessel materials.

Published: February 2019

The study analizes the requirements for instrumentation and control systems of NPP units, which are currently under modernization in accordance with the state program for long-term operation of Ukrainian NPP units. The requirements established in the documents that regulate reliability and quality of performing functions by these systems emphasize the importance of developing methods to improve the accuracy of parameter measurements, methods to increase reliability of assessing safety and reliability indexes of NPP unit operation, as well as the accuracy of personnel decisions in the presence of many uncertainties and inaccuracies in the description of initial data that affect implementing necessary management actions by personnel. The paper presents the examples of the impact of initial data uncertainty on solving the tasks of safety and reliability assessment for NPP units. The study analyzes existing methods to account and describe initial data uncertainty and modeling uncertainty in the tasks of safety and operational reliability assessment for NPP units. The possibility of applying mathematical methods and tools of interval analysis to improve reliability of solving the issues of assessing safety, reliability and efficiency of NPP unit operation under conditions of initial data uncertainty was justified. The study presents the basic principles of interval calculations, which allow considering inaccuracies when specifying the initial data, parameter uncertainties and multi-mode nature of functioning of such complex technical systems as NPP units. The prospects of applying the main theoretical provisions of interval analysis and their implementation in the form of numerical methods and models to solve current issues of assessing safety, reliability and efficiency of accident-free operation of NPP units in compliance with the state program for long-term operation were specified.
A Study of the Ageing Effect on Onsite Power System Risk Assessment for Nuclear Power Plants
Authors: Agwa A. M. , Hassan H. M.
Published: February 2019

Ageing is a general process in which properties of a component gradually changes with time or use. Ageing is one of the phenomena that effects the availability of Nuclear Power plant (NPP) electrical systems. Ageing can cause the failure rate of components to increase over time as the component wears out. Operating experience has demonstrated many components failures that have occurred as a result of ageing mechanisms such as corrosion, erosion, embrittlement, fatigue, vibration and wear. In this paper, the influence of ageing on Probabilistic Safety Assessment (PSA) results is estimated for Advanced Power Reactor (APR1400) onsite power system. Models for component ageing failure rate including surveillance test and replacement ageing control are presented for utilization. Time-dependent system unavailability due to ageing is evaluated. The average increase of system unavailability due to the ageing of system components is estimated. Components are prioritized regarding their influence on the change of system unavailability and relative increase of their unavailability due to ageing. The analysis is performed using Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE-8) software. The obtained results show the significant increase in average system unavailability after incorporating ageing effect, and the surveillance test and replacement activities can reduce this effect. Detailed time plot over plant lifetime is obtained showing the progression of ageing impact on system unavailability. The timedependent results show when, in a plant's lifetime, ageing effects become significant from a risk standpoint, and whether components are being replaced frequently enough. System components are ranked in accordance with their risk significance. As the components age, the contribution of some components in system unavailability increases, while it decreases for the others. The method presented is applicable for identification and ranking of the components that should be considered in the ageing management program.
Investigations of Neutron Radiation Shielding Properties for a New Composite Material Based on Heavy Concrete and Basalt Fiber
Authors: Romanenko I. , Holiuk M. , Nosovsky A. , Vlasenko T. , Gulik V.
Published: February 2019

The paper presents a new composite material for radiation shielding properties. This material is based on super-heavy concrete reinforced with basalt fiber, which could be used in biological protection systems for neutron radiation sources. The simulation of the neutron transport in the presented material was performed using the Monte Carlo Serpent code. Two types of heavy concretes were considered in the present paper: 1) with ordinary rubble coarse aggregate and 2) with barite coarse aggregate. For each type of concrete, the basalt fiber with dosage from 1 kg/m3 to 50 kg/m3 was added. The current transmission rates were obtained as a result of the neutron-physical modelling for neutron transport from source to detector through the proposed concrete samples with different thicknesses. The obtained modelling results were analyzed from the viewpoint of effectiveness of the radiation shielding properties. Also, elastic and capture microscopic cross-sections were considered for some isotopes and as a result, some aspects of the radiation shielding properties were clarified. The concrete with ordinary rubble coarse aggregate has better radiation shielding properties in case of low concrete thicknesses due to better neutron scattering on light nucleuses. In contrast to this, the concrete with barite coarse aggregate has better radiation shielding properties in case of high concrete thicknesses due to better neutron absorption. It is shown that the addition of basalt fiber to concrete not only improves its mechanical properties and reduces the number and size of microcracks, but also increases the ability to protect against neutron flux. The proposed composite material could be recommended for use with the following neutron sources: (D, T) neutron generators, plasma focus devices, fusion reactors and fast reactors. This research was carried out with the financial support of the IAEA, within the terms and conditions of the Research Contract 20638 in the framework of the Coordinated Research Project (CRP) “Accelerator Driven Systems (ADS) Applications and use of Low-Enriched Uranium in ADS (T33002)” within the project ‘The Two-Zone Subcritical Systems with Fast and Thermal Neutron Spectra for Transmutation of Minor Actinides and Long-Lived Fission Products’.

Definition of mutual thermal influence of containers with spent nuclear fuel at the open storage site
Authors: Alyokhina S. , Kostikov A. , Lunov D. , Dybach O. , Dimitriieva D.
Published: February 2019

The problem of spent nuclear fuel handling in Ukraine is a key issue. A half of spent nuclear fuel is currently stored in Ukraine at the open-site dry storage facility at Zaporizhzhya NPP. Thermal safety analysis should be performed as a part of the storage facility safety assessment. Thermal analysis of a container group is a poorly investigated area. As literature review shows, current results do not clearly identify mutual influence of the containers and influence of weather conditions on the thermal condition of stored spent nuclear fuel. This type of analysis could be performed using the multi-stage methodology proposed by the authors. Thus, mutual thermal influence of the containers and boundary conditions at the inlets to the ventilation duct of each storage container should be identified. Thermal processes in the container group where spent nuclear fuel is stored that are described in this paper are analyzed by solving the conjugate heat transfer problems. A row of containers under wind influence is simulated and the structure of ventilation airflow inside the containers is identified. The mutual thermal influence of the containers is absent under calm conditions, and heated air does not come from one container to another. Resulting from the simulation, boundary conditions at the inlet of the ventilation duct are specified and can be used in the iterative modelling methodology for spent fuel thermal condition. The dependence of the velocity of the inlet ventilation air in the ventilation duct of each  container in the row was defined. The container placement methodology with the purpose of decreasing the wind influence on the thermal condition of spent fuel storage was proposed. Thermal studies are carried out for the containers and storage conditions of the dry spent nuclear storage facility at Zaporizhzhya NPP.
Determination of 234U isotope in uranium-bearing materials by high-resolution gamma-spectrometry
Authors: Kutnii D. V.
Published: February 2019

The paper presents research of the existing methods of non-destructive quantitative determination of 234U isotope content in uranium bearingmaterials. Also alternative method is proposed, which is based on the approach of detector calibration on “intrinsic” efficiency. The method is based on finding the ratio of the 234U and 235U isotopes activities using their most intense gamma lines in the energy range of 120...210 keV and as a consequence does not require an estimate of the absolute efficiency of registration of the gamma detector. Certified reference standard samples of uranium-bearing materials CRM 969 and CRM 146 were used as research samples (interval of investigated enrichments on 235U 0,3…93 %), measurements were performed by means of broad-energy detector based on high-purity germanium BeGe 3830 (Canberra, USA) with area 36 cm2 and thickness 3 cm. It was shown that using of the up-to-date software products for isotopic analyses of uranium (MGAU, FRAM) it is difficult to perform of reliable estimation of 234U isotope content in depleted and natural samples due to significant measurement error (from 35 % to 100 %). In case of analyses of enriched uranium the software code MGAU systematically underestimates the content of 234U on 20…30 %. Use of alternative approach for calibration of detector on “intrinsic” efficiency for analyses of 234U results in decrease of measurement error up to 7,5 % in the whole range of enrichment on 235U (0,3…93 %) and investigated concentrations of 234U (20…9800 μg/g). The proposed method does not demand standard samples for equipment calibration and not depend on physical (chemical) form of investigated material and geometry of measurements.

Published: February 2019

This paper presents a verification of the performance of the stormwater drainage system in Gaj and Tarnogaj residential developments in Wrocław with regard to climate changes, by means of a calibrated hydrodynamic model created within the SWMM software. The verification was carried out for two criterial rainfalls: the Euler model rainfall with occurrence frequency C = 3 years and an actual rainfall with C = 5 years. Two parameters: degree of flooding (DOF) and specific flood volume (SFV) were adopted to indicate potential system overloads. The simulations showed numerous outflows from the sewers, which means, that the investigated system needs adapting to climate changes. The causes of this should be sought in the too small diameters of the sewers and so in the insufficient hydraulic capacity of the sewerage system dimensioned in the past using methods which are inadequate today.
Multi-Dimensional Cultural Safety in Academic Libraries
Authors: Dudley Michael Quinn
Published: February 2019

Over the past decade, the field of Library and Information Studies (LIS) has promoted cultural competence as a means of improving services to multicultural or traditionally underserved populations. However, critical LIS scholars have noted that cultural competence and diversity are viewed predominately as a matter of skill acquisition on the part of the library worker, rather than as one that involves a critique of the forces of structural racism, discrimination, and colonialism in society. In response, this paper proposes adapting frameworks from other professions for the library context: Multi-Dimensional Cultural Competence (MDCC) from counselling psychology, and cultural safety (CS) from Indigenous nursing. The former views cultural competence in terms of diversity factors, components, and multiple levels of foci, while the second is premised in postcolonial understandings and respect for Indigenous knowledges. The proposed synthesis, Multi-Dimensional Cultural Safety (MDCS), is established by first identifying the epistemological and ideological shortcomings of cultural competence, focusing on the need for institutional critiques as well as a recognition of racialization and power structures. Next, the two existing frameworks are explained in terms of their origins, content, and professional contexts, noting how each addresses the shortcomings of cultural competence as well as each other’s shortcomings. The proposed framework is then elaborated upon in an LIS context and illustrated with hypothetical examples.

Local implant-based delivery of rationally selected combination of chemotherapeutics has some major advantages for the treatment of glioblastoma such as: (a) 100 % bio-availability locally in brain can be achieved at the tumor site (b) avoid systemic leakage and associated toxicity, and (c) simultaneous inhibition of multiple, mutually exclusive cancer mechanisms is possible. Here, we report a polymeric brain implant capable of delivering two different drugs in recur-rent glioma cells. We have selected a combination of clinically used DNA alkylating agent, Te-mozolomide, and a DNA mismatch repair protein (Ligase IV) inhibitor, SCR-7, and delivered simultaneously into tumor spheroids formed by rat glioma cells, C6. The dual-drug loaded polymeric wafer, prepared by lyophilization method, could deliver both the drugs in a controlled fashion. To test the efficacy of this system, we have optimized an in vitro recurrent model of glioma spheroids wherein, the implant released both the drugs in a sustained fashion, thereby continuously exposing the cells to DNA methylation while inhibiting the DNA repair pathways. This leads to synergistic toxicity and inhibition of tumor recurrence for extended duration compared to free drug combination.

Authors: Rahman Mohammad Arifur , Islam ASM Shariful , Saha Jayanta Kumar , Rahman Md Lutfar , Rahman Mezanur , Quashem Md Abul
Published: February 2019

Background: Coronary artery bypass surgery (CABG) with cardioplegia has been considered the gold standard operation for coronary revascularization. Activation of compliments system after CABG surgery involves C-reactive protein (CRP). Patients with preoperative increased CRP levels have significantly higher CRP levels on postoperative days and are at increased risk of developing postoperative complications. High sensitivity CRP ( hs-CRP ) is lower concentration of CRP measured by the hs-CRP test. It is more sensitive and more useful in predicting the potential risk level for cardiovascular disease, heart attacks and strokes.

Objective: To assess the association of preoperative hs-CRP level with the incidence of postoperative arrhythmia, low output syndrome and sternal wound infection following on pump CABG surgery.

Materials & Methods: The study was cross sectional analytical study. A total of 70 patients were selected. For the purpose of analysis the study subjects were divided into two group; Group A patients with preoperative hs-CRP level <3mg/l (n=35) and Group B patients with preoperative hs-CRP level >3mg/l (n=35). The incidence of early outcome- arrhythmia, low output syndrome and sternal wound infection were observed within 30 days of surgical procedure.

Results: The incidence of arrhythmia, low output syndrome and sternal wound infection were significantly less in group A than those in group B. Logistic regression analysis showing significant correlation of hs-CRP with arrhythmia, p value is 0.005; with low output syndrome, p value is 0.003 and with sternal wound infection, p value is 0.004.

Conclusion: Preoperative hs- CRP is an important determinant of post operative outcome after CABG surgery and might be useful as predictive marker in risk stratification for postoperative complications in patients scheduled for on pump CABG surgery.

Kontribusi Tafsir Maudhu'i dalam Memahami al-Quran
Authors: Muslimin Muslimin
Published: February 2019

Secara singkat tafsir maudhu’i atau tafsir tematik dapat diformulasikan sebagai suatu tafsir yang berusaha mencari jalan keluar dari masalah-masalah yang timbul seputar al-Quran tentang kejadian-kejadian baru dengan jalan menghimpunkan ayat-ayat yang berkaitan dengannya. Kemudian dianalisis melalui ilmu-ilmu bantu yang relevan dengan masalah-masalah yang dibahas, sehingga dapat melahirkan konsep-konsep baru yang akurat dari al-Quran tentang  masalah yang dibahas. Metode yang relatif baru dan dianggap aktual dalam penafsiran al-Quran berangkat dari satu kesatuan yang logis dan saling berkaitan antara satu sama lainnya. Jadi tidak ada satupun kontradiksi ayat-ayat al-Quran, hal ini semakin jelas sebagaimana yang ditegaskan pula di dalam al-Quran itu sendiri. Asumsi dasar ini berkaitan dengan prinsip yang sangat masyhur di kalangan mufassir, yaitu bahwa sebagian ayat al-Quran dapat ditafsirkan dengan ayat yang lain. Sedangkan analisis tentang kelebihan dan kekurangan tafsir maudhu’i adalah sebagai berikut: kelebihan tafsir maudhu’i adalah dapat menjawab tantangan zaman, lebih praktis, sistematis, dinamis dan mudah dipahami secara utuh. Sedangkan kelemahan dari tafsir maudhu’i biasanya adalah memenggal ayat al-Quran dari rangkaiannya dan membatasi pemahamannya disesuaikan dengan pokok bahasannya.
