First the students have to achieve criticality, then they have to change the reactor power level and stabilize the reactor at low power, below the point of adding heat. Secondly, they increase the reactor power above POAH and observe the reactor response to control rod movement at high power levels, where temperature feedback effects are significant. The exercise ends by safe and controlled shut down of the reactor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b7e0f14 elementor-widget elementor-widget-heading\" data-id=\"b7e0f14\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Outcome \/ What you will learn<\/h5>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f297edc elementor-widget elementor-widget-text-editor\" data-id=\"f297edc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tStudents will become familiar with reactor operation, focusing on:\n<br><br>\n<ol>\n \t<li>\n<h6 style=\"font-size: 16px;\">safe reactor operation<\/h6>\n<\/li>\n \t<li>\n<h6 style=\"font-size: 16px;\">pre-startup procedures<\/h6>\n<\/li>\n \t<li>\n<h6 style=\"font-size: 16px;\">startup to low power level, change of power level<\/h6>\n<\/li>\n \t<li>\n<h6 style=\"font-size: 16px;\">reactor shutdown<\/h6>\n<\/li>\n<\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7801795 elementor-widget elementor-widget-heading\" data-id=\"7801795\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Execution<\/h5>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c69507f elementor-widget elementor-widget-text-editor\" data-id=\"c69507f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>After a discussion on the general features and systems of the reactor, reactor operation procedures and operating limits, students operate the reactor on their own.

Each student performs a sequence in which the reactor is started up and stabilized at a low power level, the power level is then changed to a higher power level, and finally the reactor is shut down. No measurements are taken.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element
