About approval of Requirements to the utility power systems important for safety of nuclear power plants
According to articles 22 and 24 of the Law of Ukraine "About use of nuclear energy and radiation safety" and for the purpose of enhancement of regulatory legal acts on regulation of nuclear and radiation safety of nuclear installations I order:
1. Approve Requirements to the utility power systems important for safety of nuclear power plants which are attached.
2. (Grigorash O. V.) to provide to department on safety issues of nuclear installations submission of this order on state registration in the Ministry of Justice of Ukraine in accordance with the established procedure.
4. I reserve control of execution of this order.
Approved by the Order of the State inspection of nuclear regulation of Ukraine of December 24, 2015 No. 234
1. These Requirements establish requirements to the device and the operation of utility power systems important for safety of nuclear power plants (further - AS).
2. These requirements extend to all AS which are designed, reconstructed, under construction and are operated.
3. These requirements are obligatory to execution for the legal entities and physical persons performing or planning implementation of the activities connected with designing, installation, adjustment, operation of the utility power systems important for safety of AS, and also designing, production of the equipment and elements for them, according to the Laws of Ukraine "About use of nuclear energy and radiation safety", "About allowing activities in the field of use of nuclear energy" and taking into account requirements of General provisions of safety of the nuclear power plants approved by the order of the State committee of nuclear regulation of Ukraine of November 19, 2007 No. 162, registered in the Ministry of Justice of Ukraine on January 25, 2008 at No. 56/14747 (with changes) (further - Conditions).
4. Amounts and terms of reduction of the utility power systems important for safety of the operating AS, in compliance with these requirements are proved by the operating organization in each case and are approved with Gosatomregulirovaniya.
5. In these requirements reducings which have the following values are used:
AB - the rechargeable battery;
AVR - automatic input of reserve;
AZ - emergency protection;
BShchU - block control panel;
RDES - reserve diesel power plant;
RShchU - reserve control panel;
SAE - system of emergency electric utility service;
SESN - utility power system of own needs;
SUSA - management system and protection.
6. In these requirements terms are used in the following values:
own needs - the size of power consumption the equipment and mechanisms in case of engineering procedure of production of electricity by the power unit;
the main scheme of the AS electric connections - set of transformers, distribution and switches, high-voltage power lines which are necessary for transfer to the electrical energy made by generators of power units EXPERTS to the integrated power system, and also ensuring own needs of power units with tension of the scheme from external sources of the electric power;
additional resources of electric utility service - the additional equipment which is provided by the AS project for providing consumers of security systems with alternating current of required capacity for the purpose of accident prevention (or reduction of their effects) with damage of nuclear fuel during de-energization of the power unit and failure of the system of emergency electric utility service;
power unit de-energization - loss of electric utility service of alternating current from all sources of electric utility service of normal operation (working and reserve transformers of own needs) of the power unit EXPERT;
self-start - capability of AS electric motors in case of electric utility service recovery (the minimum size of tension regulated by manufacturing plant) automatically to reach the rotation frequency, initial or close to it;
