DEPARTMENT OF NUCLEAR METHODS OF PROCESS ENGINEERING<br />

1. Laboratory for Flue Gases Analysis<br />

Activity profile: Experimental research connected with elaboration of removal technology for SO 2<br />

and NO x and other hazardous pollutants from flue gases.<br />

• Ultrasonic generator of aerosols<br />

TYTAN XLG<br />

• Gas chromatograph<br />

Perkin-Elmer (USA)<br />

• Gas analyser LAND<br />

Application: Determination of SO 2<br />

, NO x<br />

, O 2<br />

, hydrocarbons, and CO 2<br />

concentrations.<br />

• Impactor MARK III<br />

Andersen (USA)<br />

Application: Measurement of aerosol particle diameter and particle diameter distribution.<br />

2. Laboratory of Stable Isotope Ratio Mass Spectrometry<br />

Activity profile: Study of isotope ratios of stable isotopes in hydrogeological, environmental, medical<br />

and food samples.<br />

• Mass spectrometer DELTA plus<br />

Finnigan MAT (Bremen, Germany)<br />

Technical data: DELTA plus can perform gas isotope ratio measurements of H/D, 13 C/ 12 C, 15 N/ 14 N,<br />

18<br />

O/ 16 O, 34 S/ 32 S.<br />

Application: For measurements of hydrogen (H/D) and oxygen ( 18 O/ 16 O) in water samples with two<br />

automatic systems: H/Device and GasBench II. The system is fully computerized and controlled by<br />

the software ISODAT operating in multiscan mode (realtime). The H/Device is a preparation system<br />

for hydrogen from water and volatile organic compounds determination. Precision of hydrogen<br />

isotope ratio determination is about 0.5‰ for water. The GasBench II is a unit for on-line oxygen<br />

isotope ratio measurements in water samples by “continuous flow” techniques. With GasBench II,<br />

water samples (0.5 ml) can be routinely analyzed with a precision and accuracy of 0.05‰. The total<br />

volume of water sample for oxygen and hydrogen determination is about 2 ml.<br />

• Elemental Analyzer Flash 1112 NCS<br />

Thermo Finnigan (Italy)<br />

Application: For measurement of carbon, nitrogen and sulfur contents and their isotope composition<br />

in organic matter (foodstuff and environmental samples).<br />

• Gas chromatograph mass spectrometer<br />

GC MS-QP 5050A, GC-17A, Shimadzu (Japan)<br />

Technical data: capillary column – SPB 5, HP-5MS, SUPELCOWAX-10.<br />

3. Radiotracers Laboratory<br />

Activity profile: Radiotracer research in the field of: environmental protection, hydrology, underground<br />

water flow, sewage transport and dispersion in rivers and sea, dynamic characteristics of<br />

industrial installations and waste water treatment stations.<br />

• Heavy lead chamber (10 cm Pb wall thickness) for up to 3.7x10 10 Bq (1 Ci) radiotracer activity<br />

preparations in liquid or solid forms<br />

• Field radiometers for radioactivity measurements<br />

• Apparatus for liquid sampling<br />

• Turner fluorimeters for dye tracer concentration measurements<br />

• Automatic devices for liquid tracers injection<br />

• Liquid-scintillation counter<br />

Model 1414-003 ”Guardian”, Wallac-Oy (Finland)<br />

Application: Extra low-level measurements of α and β radionuclide concentrations, especially for H-3,<br />

Ra-226, Rn-222 in environmental materials, e.g. underground waters, surface natural waters; in<br />

other liquid samples as waste waters, biological materials, mine waters, etc.<br />

4. Membrane Laboratory<br />

Activity profile: Research in the field of application of membranes for radioactive waste processing<br />

and separation of isotopes.<br />

• Membrane distillation plant for concentration of solutions<br />

Technical data: output ~0.05 m 3 /h, equipped with spiral-wound PTFE module G-4.0-6-7 (SEP<br />

GmbH) with heat recovery in two heat-exchangers.
