Selection of Specimen Types for Irradiation Surveillance Programs

1983
Recent trends in coping with embrittlement problems in reactor pressure vessels (RPVs) show two main directions of development: (1) improvement of the vessel materials and (2) limitations of fluence over the design life of the RPV. For several reasons, however, adequate irradiation surveillance programs are still considered to be necessary in the ...

Neutron fluence calculations for embrittlement surveillance specimens in VVER-1000

Annals of Nuclear Energy, 2009
Abstract Neutron fluence spectrum calculations have been performed for the reactor pressure vessel of a VVER-1000, applying the Monte Carlo code TRAMO. Activities measured earlier in Balakovo-1 by fluence monitors, placed in special Charpy surveillance containers, are compared to TRAMO results. The average deviation from the measurements is about 5%.

Long Term Operation and Surveillance Specimen Program of WWER RPVs

ASME 2010 Pressure Vessels and Piping Conference: Volume 7, 2010
Long Term Operation (LTO) to 60 or 80 years of operation also requires a reliable information about the potential irradiation embrittlement (and also thermal ageing) of reactor pressure vessel materials. Such information is usually obtained from testing specimens within the surveillance specimen program that is designed for the design RPV life ...

[Safety surveillance and management of specimen associated with SARS in clinical laboratory].

Beijing da xue xue bao. Yi xue ban = Journal of Peking University. Health sciences, 2003
To avoid the staff's infection and environmental contamination, we establish the rules suited for severe infectious disease in our laboratory.(1) Enhance the staff's notion of safety, institute a rule for biological safety and make sure the responsibility of safety for everybody.

Surveillance Specimen Programs for WWER Type Reactors

Volume 7: Operations, Applications, and Components, 2005
Reactor pressure vessels (RPV) are components with the highest importance for the reactor safety and operation as they contain practically whole inventory of fission material but they are damaged/aged during their operation by an intensive reactor radiation.

Enterovirus detection in stool specimen: relevance for poliovirus and enterovirus surveillance.

Archives de l'Institut Pasteur de Tunis, 2009
Detection of enterovirus genome by PCR in clinical samples is now extensively used for the diagnostic of enterovirus infections given its rapidity and high sensitivity. In contrast, its use in surveillance programs targeting specific enterovirus serotypes remains less frequent.

Development of Reconstitution Technology for Surveillance Specimens in Japan Power Engineering and Inspection Corporation

2001
In order to establish reconstitution technology for the surveillance specimens of RPV steels, a project was started in 1996FY. We focus on a correlation between the reduction of absorbed energy and the interaction of heat affected zone (HAZ) and plastic zone, to establish applicable reconstitution conditions for Charpy specimens. The plastic zone width

Structural Integrity Lessons Learned in WWER RPV Surveillance Specimen Programs

2018
Surveillance specimen programs in reactor pressure vessels (RPVs) are an important part of monitoring material property changes during reactor operations. Results of testing such specimens in surveillance programs, if properly designed and operated, should be the basis for assessing RPV integrity and lifetime.

Surveillance of Listeria monocytogenes in human and environmental specimens in Nova Scotia, 1974 to 1981.

Clinical and investigative medicine. Medecine clinique et experimentale, 1985
We examined specimens for L. monocytogenes using the "cold enrichment" technique of Gray et al. (J. Bacteriol., 55: 471, 1948) and a nalidixic agar plate (Ann. Inst. Pasteur 111: 90, 1966). Between 1974 and May 1981, we isolated L. monocytogenes from four of 5,255 specimens (rectal, vaginal and placental swabs; blood; spinal fluid; semen; necropsy ...
