1. Regulations and rules on ensuring nuclear and radiation safety "The organization and accomplishment of welding works on subjects to use of atomic energy" (further – Rules) establish the main technical requirements to safe handling of radiation objects, and also to the activities connected with operation of subjects to use of atomic energy including to welding production, quality control of welding works (welding), carrying out certification of personnel of welding production and production certification of technology of welding (further – production certification) the companies having special permission (license) for the right of implementation of activities in the field of use of atomic energy and sources of ionizing radiation (further – the companies), to the welding equipment, welding materials in case of production, installation, repair of systems, elements and devices of nuclear installation and (or) Item of storage.
2. The equipment and pipelines are classified by groups A, B and C which correspond 1, to 2 and 3 classes of safety according to the regulations and rules on ensuring nuclear and radiation safety "General provisions of safety of nuclear power plants" approved by the resolution of the Ministry of Emergency Situations of the Republic of Belarus of April 13, 2020 No. 15.
The group A turns on the equipment and pipelines carried to elements of 1 class of safety.
The group B turns on the equipment and pipelines carried to elements 2 classes of safety, and also the equipment and the pipelines carried to elements 3 classes of safety, failure or destruction of which leads to unremovable regular means of subject to use of atomic energy to leakage of the heat carrier which is directly contacting to the fuel elements or to failure to carry out by any security system of the functions.
The group C turns on the equipments and pipelines carried to elements 3 classes of safety which did not enter into group B failure or destruction of which brings to removable regular means to leakage of the heat carrier which is directly contacting to the fuel elements requires enforcement of security systems and leads to failure of one of channels of any security system.
3. If any element at the same time contains signs of different classes (groups) of safety, then it shall be carried to higher class (group).
4. The sites dividing elements of different classes (groups) of safety shall be carried to higher class (group).
5. For welded connections of the equipment and pipelines of nuclear installations with pressurized water reactors the following three categories of welded connections are established:
The I category – welded connections of the equipment and pipelines of group A;
The II category – the welded connections of the equipment and pipelines of group B working constantly or periodically in contact with the radioactive heat carrier;
III category – the welded connections of the equipment and pipelines of group B which are not working in contact with the radioactive heat carrier and also welded connections of the equipment and pipelines of group C.
Depending on working pressure welded connections II and III of categories are subdivided into the following subcategories:
IIA subcategory – the welded connections working under pressure of over 5 MPas;
IIV subcategory – the welded connections working under the pressure up to 5 MPas inclusive;

1. Regulations and rules on ensuring nuclear and radiation safety (further – Rules) establish technical requirements to safe handling of radiation objects, and also to the activities connected with operation of subjects to use of atomic energy including to preparation of production and technology of welding works, determine categories of welded connections, methods and amounts of control and regulation of quality evaluation of welded connections when designing, designing, production and installation, and also repair of elements of the localizing security systems (further – LSB) nuclear power plants (further – the NPP).
2. For the purposes of these rules the following terms and their determinations are used:
defect – inadmissible variation from the requirements established by these rules;
depression – difference between pressure in the vacuum camera and atmospheric pressure.
The list of defects is determined in appendix 1.
3. Project and design documentation shall be developed taking into account need of control of welded connections according to these rules, except as specified, of the these rules specified in Item 7.
4. Control of the LSB welded connections shall be made according to the technology documentation (further – TD) developed according to requirements of these rules which shall be approved with the specialized organization (further – SO).
5. The list of the specific details and designs which are subject to control and also methods and amount of control of welded connections are established by the project (design) organization according to requirements of these rules and specifies them in specifications (further – TU) product, design (project) documentation (further – KD).
6. Control by each method (nondestructive and (or) destroying) should be carried out on state standards. In the absence of the specified state standards monitoring procedure according to technology instructions, developed SO is allowed.
7. In case monitoring procedure or in necessary amount technically is impossible for one of the provided methods or when correction of defective welded connection can reduce its operational reliability, the allowed departures draw up in the form of the technical solution approved with the project or design organization, the manufacturer or the mounting organization (further – the company), SO, the customer.
