Safety pharmacology seeks to identify the safe and appropriate dosage for a particular drug or therapy. In this scenario, neurobehavioral testing is conducted during the preclinical trial phase to determine whether a drug is likely to produce adverse neurological effects.

These tests are required for regulatory approval of new drugs and therapies. Analysis of the strength of our core tank shows that it can withstand much higher forces (5 g horizontal and 3 g vertical simultaneously).

The arrangements for reactor safety must provide for the prevention of any hazardous release of radio­ active material. While the safety of the reactor staff would be ensured by normal health physics regulations, the evaluation of reactor safety has to take into account the wider problem of contamination affecting the general public.

A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. This neutron current may affect reactor operation during low power maneuvers (e.g., start-up) and may provide a sufficient reactor start-up source.

Yet it is far from being a new idea. It can be traced back to, at least, the early. field of reactor safety and thermal-hydraulics. These difficulties can plague the reactor simulations unless handled with proper care. To illustrate these difficulties, the US NRC Consolidated Thermal-hydraulics Code (TRAC-M) was exercised with selected numerical benchmark problems.

High confidence in fission system performance can be obtained through relatively inexpensive non-nuclear tests performed in relevant environments, with the heat from nuclear fission simulated using electric.
