DECLARATION
Czechoslovak Atomic Energy Commission
of 10 October 1990
on ensuring the quality of selected installations in terms of nuclear safety of nuclear installations
The Czechoslovak Commission on Atomic Energy pursuant to Section 21 of Act No. 28 / 1984 Coll., on State Control over Nuclear Safety of Nuclear Equipment, provides:
INTRODUCTORY PROVISIONS
Subject matter and purpose of the Order
The Decree sets out the essential requirements for ensuring the quality of equipment, machinery, parts and materials, construction parts and structures, means of automated management of technological processes, including technical and software equipment and electrical power supply systems relevant for nuclear safety (1) (hereinafter referred to as "selected equipment ') of nuclear installations (2), and determines binding procedures for implementing technical and organisational measures related to the quality of the selected equipment in order to ensure nuclear safety of nuclear installations.
Basic concepts
(1) The quality of the device is a summary of the characteristics of the device which make it conditional on its ability to meet the specified needs in accordance with its designation.
(2) By establishing the quality of the equipment selected, for the purposes of this decree, it means establishing the requirements for its characteristics which make it conditional on the performance of the functions for which it is intended.
(3) The quality assurance of the selected equipment shall be a summary of the activities planned and systematically carried out to ensure that the selected equipment complies with the specified quality requirements.
(4) For the purposes of this decree, the quality assurance programme shall mean a dossier containing a summary of the technical and organisational measures and activities, including controls, related to the achievement and maintenance of the specified quality of the selected equipment.
(5) For the purposes of this decree, the quality assurance documentation shall mean the list of selected establishments, the individual quality assurance programmes, including their annexes and the documentation related thereto, in particular the quality documentation and the normative technical documentation.
(6) For the purposes of this Order, quality documentation shall mean documentation containing evidence of the quality of the elements and equipment, of the performance of the activities affecting the quality, the characteristics of the materials, welds or elements and equipment and of the results of the activities carried out to evaluate the condition and the quality of the selected equipment.
(7) The operation of a nuclear installation for the purposes of this Decree covers activities from the entry into service of a nuclear installation to its final decommissioning, including the operation of shut-down operations, maintenance, fuel exchanges, inspections, tests, inspections and the like.
(8) For the purposes of this decree, operational checks shall mean all checks on selected installations carried out during the period of operation of the nuclear installation.
(9) Security functions for the purposes of this Decree are those functions which are necessary to prevent or mitigate the consequences of an accident on a nuclear installation.
(10) For the purposes of this decree, normal operation shall mean all the states and operations of the planned operation of the nuclear installation, respecting the operating limits and conditions for its safe operation. These are mainly the launching, steady operation and shutdown of the nuclear reactor, increasing and reducing its performance, its partial and full load, maintenance, repairs and fuel exchange.
(11) Abnormal operation means, for the purposes of this decree, unplanned stocks, operations and events but the occurrence of which can be expected to occur when a nuclear installation is operated. They are mainly emergency shutdown, sudden drop in load, turbine failure, power loss from the mains. However, such operational conditions shall not lead to damage to the fuel cells or to a breach of the integrity of the pressure circuit of the nuclear reactor coolant and, after they have been completed or their causes and consequences removed, the nuclear device shall be capable of normal operation.
(12) For the purposes of this decree, emergency conditions shall mean all events caused by failure or breach of construction structures, technological files and equipment, external influences or operator errors which adversely affect the safety of the operation of the nuclear installation and lead to a breach of operating limits and conditions and may cause a breach of fuel cells.
(13) For the purposes of this Decree, safety systems are those which are essential to nuclear safety, which are designed to ensure the safe shutdown of the nuclear reactor under any conditions, to remove heat from the core zone or to reduce the consequences of abnormal operation and emergency conditions.
SELECTED EQUIPMENT
Principles for the breakdown of selected installations
Selected installations shall be subdivided into three safety classes according to their importance for the safe operation of the nuclear installations, the safety functions of the system of which they are part and the severity of the consequences of any failure.
Safety classes of selected devices
(1) The provisions of paragraphs 2, 3 and 4 apply to equipment for the storage, processing, storage and transport of nuclear materials which are consumed in a fissile chain reaction or arising from the operation of a nuclear reactor, as well as to investment and operation units which include a nuclear reactor which operates on the principle of fissile chain reaction by heat neutrons and is moderated and cooled by light water. In the case of other nuclear installations, the security classes shall be determined by the Czechoslovak Atomic Energy Commission (hereinafter referred to as the Commission) according to the nature of those installations and the purpose for which they are intended.
(2) Selected devices classified in Security Class 1 are devices forming the limit of the pressure circuit of the nuclear reactor coolant, except those devices whose damage can be compensated by a normal coolant replenishment system.
(3) The selected equipment in Security Class 2 is nuclear fuel and equipment:
(a) forming the limit of the pressure circuit of the nuclear reactor coolant which does not belong to safety class 1;
(b) for the decommissioning of a nuclear reactor under abnormal operation in states likely to lead to emergency conditions and for the decommissioning of a nuclear reactor in order to mitigate the consequences of emergency conditions;
(c) to maintain sufficient coolant for cooling the core of the nuclear reactor during emergency conditions in which the pressure circuit of the nuclear reactor has not been breached and even after these conditions;
(d) for heat removal from the core of the nuclear reactor (3) in breach of the reactor coolant pressure circuit in order to reduce fuel damage;
(e) for the removal of residual tepla3) in normal and abnormal operation and in emergency conditions where the integrity of the pressure circuit of the nuclear reactor coolant has not been breached;
(f) necessary to limit the leakage of radioactive substances from the protective envelope under and after emergency conditions;
(g) intended to limit the penetration of ionising radiation outside the protective envelope in and after emergency conditions;
(h) necessary for the performance of safety functions for the supply of energy or for the control of other components included in safety class 2.
(4) Selected installations in Security Class 3 are:
(a) to prevent unacceptable transition processes associated with changes in reactivity;
(b) to maintain the nuclear reactor under conditions of safe weaning, after each weaning;
(c) to maintain sufficient coolant for cooling the core of the nuclear reactor in normal and abnormal operation;
(d) draining heat from safety systems up to the first accumulation volume (4) sufficient for the performance of safety functions;
(e) necessary to maintain the exposure of the population and workers of nuclear equipment under specified limits during and after emergency conditions associated with the leakage of radioactive substances and ionising radiation from sources located outside the protective envelope;
(f) necessary to maintain environmental conditions within the nuclear installation, necessary for the operation of safety systems and for the access of workers to safety-critical activities;
(g) to prevent radioactive releases from irradiated fuel transported or stored inside a nuclear installation outside the nuclear reactor cooling system during all normal and abnormal operations;
(h) for the removal of disintegration heat from irradiated fuel stored inside a nuclear installation outside the nuclear reactor cooling system;
(i) necessary to maintain sufficient undercriticism of the fuel stored inside the nuclear installation outside the nuclear reactor cooling system;
(j) necessary to limit discharges or releases of solid, liquid or gaseous radioactive substances and ionising radiation below the limits laid down during all normal and abnormal conditions of operation;
(k) necessary for the performance of safety functions for the supply of energy or for the control of other components included in safety class 3;
(l) necessary for the performance of safety functions to ensure the performance of other components included in safety classes 1, 2 and 3 which are not related to power management or supply;
(m) intended to prevent or reduce the consequences of disturbances of other components or structures of safety systems classified in Security Class 1, 2 or 3.
