The ISKRA-5 pulse laser device is assigned for research in nuclear fusion.
It has 12 channels working synchronously against common load to provide different
As the main power supply it uses the stored capacitor energy.
The power used (67 MJ) is sufficient to cause fatal damage.
Thus, safety must be guaranteed.
Therefore ensuring of power supply reliability is one of main functions of control system.
This requirement can be satisfied by improving power supply viability,
the stability increase using optimal mode of the capacitor battery charge and by emergency
energy discharge when one of the capacitor sections fails.

VNIIEF is the pioneer and world's leader in the development of and research
on nuclear-pumped lasers, the systems that convert fission fragments' energy
directly to light. To show feasibility of self-contained reactor-laser systems
having continuous wave operation and generating light, particularly,
laser radiation other than traditional energies, there was an idea to develop
and test a multi-unit laser module to be operated by BIGR reactor under pump-through
conditions as exist in the nuclear power reactor cores. Two years ago,
this BIGR - operated module was launched and tested.
This was the first demonstration of a nuclear laser device's continuous-wave
operation during 1.5 s (the quasi-pulsed operation time of BIGR reactor).
The performance was shown to be nearly as predicted, and thus proved the
physics concepts and approaches embodied in CW power reactor-laser can meet
the needs of the latest industrial technologies.
Currently this system is a prototype of a self-contained nuclear-to-optical converter,
and nuclear light station in the future.

20 km Sarova Map
Arzamas-16 is located on the lands of the former Sarov Monastery,
75 km south-west of Arzamas in the Nizhegorod region,
approximately 400 km from Moscow. The old town of Sarova was known for its monastery built
in 1654 on the site of a Tatar fortress abandoned in the 15th century.
The monastery's most famous resident was St. Seraphin Serovsky, one of three principal
saints in the Russian Orthodox church who lived from 1759 to 1833.
Historically, the monastery town was called Sarov for St. Seraphim Serovsky.
When the Soviet nuclear weapons program started, the town name was changed to Arzamas-60,
a postal code designation to show that it was 60 km from the city of Arzamas.
But the '60' was considered too sensitive, and the number was changed to 16.
In 1947 the city of Sarov (Arzamas-16) disappeared from all official Russian maps.
Boris Yeltsin visited the site in February, 1992 and the existence of the area was made public in 1994.
Located within a hexagonal restricted area of 232 km2, surrounded by an outer defensive ring 25 miles out.
The township of Sarov occupies 29 km2 and is located in the northern part of the restricted area, south of the airport.
VNIIEF's main administration building is located near the Sarov Monastery, the symbol of Arzamas-16.
There are several protected areas within the city, which are probably associated with VNIIEF.
The Avangard plant is located in the western part of the restricted area.
The southern part of Arzamas-16 is covered with woods and contains multiple experimental facilities and storage areas.
