On Forecast of Future Glaciations in Terms of Disposal Safety of Radioactive Waste
From the point of view of disposal safety of radioactive waste, especially high radioactive waste, and also spent nuclear fuel, one of the tasks is forecast of glaciations which can render adverse influences both on a disposal site, and on waste. In the work the attempt is undertaken to consider an opportunity of recurrence of glacial periods for the 65-th parallel of the Northern Hemisphere in the future. Thus as the basic reason of climate change on the Earth the authors have accepted the so-called astronomo-physical hypothesis which explanes climate changes by space processes, in particular, the theory of Рњ. Milankovich. The received results show that the nearest appreciable glaciation is possible approximately in 16 ka, and comparable by the temperature parameters with the last glacial period taking place in the Earth (as Vurm-3) - approximately in 55 ka.

Minimization of the radiation impact of inhabitants resulted from the underground storage facility for non-processable spent nuclear fuel in the crystalline rock of the Kola Peninsula (2 stage)
The results of the 2nd final stage of investigations within RFBR N 03-05-96161 Project have been presented in the paper, the studies being carried out in the radiation impact of the regional inhabitants resulted from the underground storage facility for non-processable spent nuclear fuel (SNF) placed in the crystalline rock of the Kola Peninsula. This underground facility for long-term SNF controlled storage has been assumed to be attacked by terrorists, thus, becoming a final disposal facility. The results of numerical tests of dissolved radioactivity migration from the storage facility in the geosphere have been given. The analysis of dynamics of the concentration of the basic dose-contributing radionuclides and dose rate for people supplied with water from water intake points has been carried out. The location of the underground SNF storage at over 100 m depth has been shown to be more safe even in case of an accident for hydraulic gradient range typical for the region candidate sites.

On the safety of underground regional repository for radioactive waste (RW) on the Kola Peninsula
The paper presents the results of investigations of a safe underground regional repository for radioactive waste (RW) in the North-West Russia. The approaches, initial data on the level of radiological dangerous nuclides' activity, model representations of a repository (near field, far field, biosphere) have been described. The results of numerical experiments which allowed to the authors of the Project to make preliminary conclusions about the adequacy of all the sites examined for a RW-repository disposal have been considered.

On diffusion transfer of long-lived radionuclides in engineered barriers of an underground spent fuel and radioactive waste disposal facility
The paper has analyzed the development of Russian personalizm and formation of its basic tendencies. Profound influence of the ideas of mental substantiality and the monad doctrine of Leibniz on Russian philosophers has been shown. Kant teaching and its influence on formation of traditions of Russian personalizm have been considered in the paper.

The analysis of the probabilistic scenario "Pumping well"
The diffusion transfer of long-lived radionuclides in engineered barriers of an underground spent fuel and radioactive waste disposal facility has been studied. Two schemes of barriers have been considered: the constant thickness of the excavation disturbed zone of a rock mass and the constant thickness of the near-field zone. Concrete and bentonite are considered as materials to be used in engineered barriers' construction. The choice of nuclides, the parameters for their migration in the studied media, the time period of investigation and the underground facility parameters has been substantiated for consideration. The scenario of normal evolution is taken as a scenario of evolution of an underground radiation-hazardous materials disposal facility. According to this scenario, diffusion is considered to be the transfer mechanism dominating in the near-field zone of the facility. Using the PORFLOW code, an algorithm of numerical solution of a diffusion equation have been chosen as an mathematical apparatus of the models proposed, taking the mechanism of radioactive decay into account. As a result, the spatial distributions of radionuclide concentrations through the thickness of the barrier system as well as the migrating isotopes' concentration dynamics in the near-zone of the underground facility have been calculated. The results analysis has enabled, firstly, to estimate the maximum radionuclide concentration in the conjugate zone between the "excavation disturbed zone" and "host geological formation", and, secondly, to show "in digits" the decrease in the radionuclide concentration due to the concrete and bentonite thickness.

Underground hydrosphere pollution analyzed for different scenarios of evolution of an underground radioactive materials disposal facility
During long-term series of instrumental observations in the natural and man-caused system "Khibiny" an abnormal character of the modern differentiated movements around the Saamsky fault has been discovered. The internal zone of the fault is stably uplifting in relation to the containing massif of rocks in conditions of the insignificant variable-polarity fluctuations. Such character of massif deformations in the Saamsky fault area is probably caused by influence of the high subhorizontal pressure and simultaneous influence of the man-caused factors. In particular it was caused by the non-uniformity of deep mining in different parts of the deposit Kukisvumchorr (Kirovsk and Yukspor mines).

Analysis of coefficients of tracer concentration reduction by protective barriers
The results analysis of numerical experiments of ground waters pollution at potential sites of underground radiation-hazardous object location has been carried out. The authors have considered three object evolution scenarios (normal evolution and two alternative ones: with convection stream of ground waters over object engineering barriers and error in radionuclides sorption properties determination in materials of engineering barriers and host rock).

Modeling of thermal mode of underground object of long-term storage of spent nuclear fuel
On the basis of studying geological sections, petrographic thin sections and also recalculation for the petrological indexes-diagrams of chemical analyses of Triassic basalts and liparites of the Middle Transural, the conclusion about fractioning acidic melts magma from initial tholeitic bР°salt magmas has been made. Similar processes are supposed in oceanic lavas of Iceland, Easter Island and Hawaian Islands as well.

Effect of "conductive" bore in porous medium
The numerical experiments of ground water contamination have carried out for horizontal mining working put out of operation and turned to be unsealed. Spatial-temporal contamination distribution has been studied under constant hydraulic gradient but under different coefficient of hydraulic conductivity in the mining working. It has been shown that from the environmental perspective it is not allowed to leave the mining workings unsealed after its closure.
