Purpose of the development: PTC PTC steam leakage control "Nitrogen-16-PG" is designed for continuous monitoring of the value of coolant leakage from the primary to secondary circuit by detecting gamma radiation isotope 16 N in the live steam. PTC provides: - Continuous monitoring of 16N activity in live steam; - Determination of the leakage in the steam generator (SG) (kg / hr); - Identification of GHG having flow; - Alerting controlled parameters of acceptable levels.

Recommended application field: Control of radiation safety.

Technical characteristic: Energy range of gamma radiation, MeV: 0,2-8,5; range of measured values of leakage, kg / h: 0.05-50.0; basic error in determining the magnitude of leakage leakage of more than 0.5 kg / h = 0.95 for the reactor power for 100% max%: 20-30; operating mode setting time, no more, h 2; continuous operation: continuous; mean time to failure, hours: 20000; average lifetime, at least, years: 30; the number of channels at least 1024.

Advantages over analogues: PTC devices implemented on the basis of determining the leakage of steam generators at 16N «UDPP - 01" ACT ", which have been successfully tested on the OP" Rivne "in October 2002 and ETA" Zaporizhzhya "in April 2004 PTC can operate as independent from other control systems of radiation (IBS) and in their composition.

The development stage readiness: Introduced in production

Description of the development:
()
Ingredients: - Spectrometric information analyzer AMA- 10; - Block thermostabilization BTS2 ; - Detection unit thermally stabilized ; - Protection of the detector ; - Cross the block ; - Unit calculations and validation leaks ( Brive ) . The system includes a detection unit , which has the original heat setting system capable of maintaining a stable temperature inside the unit in the range from 25 0C to 30 0C , including and at high ambient temperatures. The software has an algorithm calculate the magnitude of leakage of primary coolant water in GHG for NPP with VVER -1000 Activity 16N. The manufacturer guarantees author's support and service throughout the life of the system . Author's support makes it possible to take into account all the requirements of Ukrainian regulations and promptly respond to the comments of operating personnel . Reliability and ease of operation . The system can operate independently of the other as a radiation monitoring systems (IBS ) and in their composition. The system is designed for WWER -1000 PTC " Nitrogen -16 -PG " designed to meet the design and operational features of nuclear power plants that operate in Ukraine.
