In this work, a Monte Carlo based coupled depletion code (MCNP5/ORIGEN-S) is utilized to provide reference solutions in order to assess the accuracy of pin power and pin exposure reconstruction methods in the current commercial and licensed three-dimensional (3D) nodal Light Water Reactor (LWR) core design codes.
Any uncertainties, associated with the technical approach and numerical methods used to perform pin exposure calculations may cause either peak power exposure to exceed the Nuclear Regulatory Commission NRCC) exposure limit or lead to excessive conservatism and thus inefficient fuel utilization.
Moreover, it is difficult to pin down the level of exposure to one particular country in a portfolio made of various funds and individual companies all with different holdings.
The bank declined to comment yesterday on its potential liability in the matter, and pinning down the bank's exposure is difficult because prosecutors have wide discretion in deciding whether to pursue charges against a company.
Some cameras are equipped with pin-registering mechanisms, which hold the film firmly in place in the exposure gate, with the pins engaging sprocket holes.
In case of Bluetooth, it has the risk of guessing of a PIN (Personal Identification Number) and the exposure of a random number according to a security mode [8, 9].
These progressed from pre-malignant changes (nuclear atypia, focal hyperplasia) and low grade prostatic intraepithelial neoplasia (PIN) at 16 20 wks post-tamoxifen exposure, to overtly malignant lesions by ∼1 yr of age, characterized by high-grade PIN and microinvasive carcinoma.
Both failures were caused by cracks that began at the articular surface and caused exposure of the Steinmann pins at the proximal tibia articular surface.
Trisha Donnelly's "Satin Operator," an abstract image made by rolling a photograph on a flatbed scanner during the exposure process, is the lone exception, pinned to the wall like an exotic butterfly.
Prenatal LPS exposure induced social deficits (social interactions, pinning, and darts) in juvenile rat offspring, as well as elevated plasma IL-6 levels.
Already by then he had achieved complete exposure, with his face on T-shirts, pins, coins, and cakes, nostalgically recreating the iconography of a Soviet strongman in a consumerist framework.
