³H and ¹⁴C measurements of the irradiated graphite from the decommissioned VVR-S reactor in NIPNE Bucharest

Abstract

Accelerator Mass Spectrometry and Full Combustion method followed by liquid scintillation counting were applied to measure the accumulated 14C in the thermal column of the decommissioned VVR-S reactor in NIPNE Bucharest.

Ultrasensitive detection of 244Pu in environmental samples by accelerator mass spectrometry

“…The constructive characteristics of the 1 MV AMS facility have been extensively described in ref. [33][34][35][36][37], and also, the AMS system from CIRCE is described in ref. [38][39][40][41].…”

Release of C-14 and H-3 from Irradiated Graphite of the Thermal Column of VVR-S Reactor to Gas Phase

“…The 14 C and 3 H specific activities of the irradiate graphite used in the experiment were determined by a full combustion method followed by isotopes separation and liquid scintillation counting. The results have been presented in a previous paper [5].…”

The Assessment of the Radioactive Inventory for the Solid Wastes from VVR-S Nuclear Research Reactor Decommissioning

“…al. in paper [8] using oxidation method in two sampling steps in oxygen atmosphere [8] for radiological characterization of the irradiated graphite from VVR-S research reactor. The results are shown in Fig.…”
