Reactivity margin evaluation software for WWR-c reactor [PDF]

Nuclear Energy and Technology, 2018
The WWR-c reactor reactivity margin can be calculated using a precision reactor model. The precision model based on the Monte Carlo method (Kolesov et al. 2011) is not well suited for operational calculations. The article describes the work on creating a software package for preliminary evaluations of the WWR-c reactor reactivity margin.

Status of UCN Source at WWR-M Reactor [PDF]

KnE Energy, 2018
The WWR-M reactor at PNPI is going to be equipped with an ultacold neutron source of high density. Method of UCN production is based on their accumulation in the super fluid helium due to particular qualities of that quantum liquid. The possibility of maintaining the temperature T = 1.371K with a thermal load of P = 60W was shown experimentally, while ...

Understanding BIPV performance with respect to WWR for energy efficient buildings

Energy Reports, 2022
Globally, the building sector absorbs 40% of energy, which is expected to reach double or triple by 2050. Building-integrated Photovoltaic (BIPV), known to the use of PV to replace long-established building envelopes such as windows, roofs, and walls which will create energy while simultaneously protecting the inside the structure from the harsh ...

Optimization of conditions for topaz irradiation in the WWR-K reactor [PDF]

Nukleonika
Abstract Activation of impurities in topazes happens due to irradiation with thermal neutrons (induced radioactivity occurs), which complicates their further handling. This leads to the need for their long cooling for safe use. The Institute of Nuclear Physics (Kazakhstan) is conducting R&D to develop a method for the effective ...

Concept of UCN Source at WWR-K Reactor (AlSUN)

Physics
We present the concept of an ultracold neutron (UCN) source with a superfluid He-4 (SF 4He) converter located in the thermal column of the WWR-K research reactor at the Institute of Nuclear Physics (INP) in Almaty, Kazakhstan. The conceptual design is based on the proposal of accumulating UCNs in the source and effectively transporting them to ...
