Releases of off-gases, whether radioactive or non-radioactive, are permitted only within the following technical limits and conditions. Uncontrolled releases are prohibited. Releases of uncontrolled gaseous radioactive effluents are prohibited, with the exception of the diffuse releases cited in paragraph IV of Article 12.
Facilities are designed, operated and maintained to limit effluent emissions to The atmosphere. These emissions shall be collected at source, channelling and, if necessary, processed in accordance with paragraph IV of Article 2, so that the corresponding discharges are kept as low as reasonably possible.
Conditions for The collection, treatment and release of off-gases are such that they do not cause any risk of ignition or explosion or the production of new polluting substances due to the mixing of the effluent.
Effluent Discharges In no case shall gaseous radioactive material add actinides to the environment.
I.-Treatment devices are designed to cope with variations in the flow, temperature, or composition of the effluent to be treated, in In particular on the occasion of the start or stop of the installation causing the discards.
II. -Releases to the atmosphere are evacuated, after treatment, through chimneys or exhaust systems designed to allow for good release of releases. The form of the pipes, especially in their nearest part of the outlet to the atmosphere, is designed to maximize the ascent and diffusion of the effluent into the atmosphere. These ducts are implanted in such a way as to prevent the discharge of discharged effluent into nearby ducts or intakes.
The operator must take into account the local meteorological parameters for gaseous radioactive releases Concerted and spread them for the greatest possible dilution.
I.-Radioactive effluents from the Nogent nuclear site are released by two chimneys known as "chimneys of nuclear auxiliaries (BAN)". They are intended to reject all radioactive gaseous emissions from reactor installations. These emissions are collected, filtered and eventually stored before release to the atmosphere. These chimneys are attached to the reactor buildings.
Off-gases from the effluent treatment building are released from the stack 1 stack.
These stacks have the following characteristics:
-height Minimum above ground: 70 m;
-inside diameter: 3 m.

The gaseous radioactive effluents from the Nogent nuclear power plant are rejected exclusively by the chimneys referred to in paragraph I of Article 9. For this purpose, the operator shall, in particular, ensure the correct lineage of the ventilation circuits. On the one hand, the operator may, on the one hand, carry out permanent discharges (ventilations of buildings) with continuous monitoring and, on the other hand, concerted discharges of radioactive effluents previously stored in reservoirs And the deflating of a reactor building (BR) and requiring prior checking before discharge.
For any operation leading to the communication to the atmosphere, via the ventilation circuits, of any capacity Containing radioactive waste, the flow rate shall be adjusted to promote dilution and avoid exceeding the stack alarm threshold. In this context, gases must be characterised directly or indirectly (e.g. through primary activity) in advance of the discharge. These precautions apply in particular to the following operating operations:
-oxygenation of the ball from the primary circuit volumetric control circuit;
-the primary circuit.
Opening the pressurizer man hole Should lead to similar precautions.
Before discharge, radioactive hydrogenated effluents must be stored for a minimum period of time, unless prior agreement has been reached by the DGSNB, thirty days.
Minimum total capacity of tanks Storage of hydrogenated gaseous radioactive effluents (RS tanks) is 1500 m³ per unit reported under standard conditions of temperature (273.15 Kelvin) and pressure (101.3 kg Pascal). It is distributed in at least three tanks, identified RS1-1, RS1-2, etc., for Band 1, and RS2-1, RS2-2, etc., for Band 2. The temporary unavailability of a reservoir must be the subject of a prior agreement of the RSNB.
All provisions must be made to make it impossible to discharge effluents from more than one RS reservoir at a time or to proceed Simultaneously the deflating of a reactor building. This last operation can only take place for one reactor at a time.
All gaseous radioactive effluents are filtered before release. The concerted discards from the RS tanks are systematically accompanied by a passage on iodine traps.
Installation devices for specific installations such as iodine traps are doubled by a manual command. The operator shall take the necessary maintenance and periodic inspection arrangements in order to ensure that the efficiency of the filtration systems required by the safety studies is sufficient at all times. The effectiveness of the commissioning devices is tested once a year.
