Design of the HTR-10 test reactor represents the basic features of the modular HTGR. The reactor core and steam generator are housed in two steel pressure vessels arranged in a side-by-side configuration as shown in Figure 4.1. These vessels are tied together by a connecting cross-vessel Chapter 5, "License Renewal and Aging Management for Jan 01, 2013 · @article{osti_1108545, title = {Chapter 5, "License Renewal and Aging Management for Continued Service}, author = {Naus, Dan J}, abstractNote = {As of August 2011, there were 104 commercial nuclear power reactors licensed to operate in 31 states in the United States. Initial operating licenses in the United States are granted for a period of 40 years.

Numerical Analysis on Ingress of Coolant Event in Vacuum

The thermal hydraulic characteristics in the vacuum vessel (VV) of a fusion reactor under an ingress of coolant event (ICE) and a loss of vacuum event (LOVA) were investigated quantitatively using OSHA Technical Manual (OTM) Occupational Safety and OSHA Instruction TED 01-00-015. The OSHA Technical Manual (OTM) provides technical information about workplace hazards and controls to OSHAs Compliance Safety and Health Officers (CSHOs). This information supports OSHAs enforcement and outreach activities to assure safe and healthful working conditions for working men and women.
