Evidence-Informed Decision-Making: Improving Outcomes Through Research
Research evidence is essential for enhancing outcomes in education. Teachers must continuously improve their practices, and collaborative communities can support this journey. Examples like Teacher Learning Communities and Developmental Observations showcase effective strategies in evidence-informed decision-making. Emphasizing professional dialogue and reflection, these practices contribute to creating a culture of continuous learning in educational settings.

Ground Test Sub-Tasks Current 27 June 2017 .1
BWXT NTP at SSC (current) Licensing General Support Licensing Environmental Report Gap Assessment Subscale Test Component Selection Subscale Test Scaling Analysis Subscale Test I&C Approach A3 Full Scale Test ROM Estimate Assessment .2
A3 Full Scale Concept Design Start with NASA NTP ground test facility (GTF) design concept Supplement with BWXT System Gap assessment Apply scaling requirements to derive the demonstration .3
Exhaust Capture Demonstration Help establish full-scale control system design basis Use physical components scaled from full-scale system(s) Determine required input parameters and time responses Define and refine processing algorithms Define and validate response and control actions Demonstrate response to potential casualties Control system pressures/temperatures within acceptable bounds Demonstrate system response to core damage NRC expects demonstration, not simply analysis Ability to capture and contain fission products Potential tests include cesium, strontium, iodine, krypton, and xenon Nominal operations Translate Design Basis into I&C requirements and features .4
Subscale Facility Conceptual Design Flow Diagram Considers Initial Configuration Information Provided NUCLEAR REACTOR SIMULATION (Point Kinetics Model, MP 10, 13, and 17) A-3 CONOPS (MP 10) HYDROGEN CONVERSION (Different Operating Configurations, MP 10, 11, 13, and 17) SIZING (MP 10) EXHAUST CAPTURE (What to capture, MP 10 and 17) POSTULATED ACCIDENT CONDITIONS (Decay Heat Removal, Debris Capture, MP 10, 13, and 17) .5
Component Selection and Scaling Evolution Subscale Facility Geometry Needs and Impacts of Chosen Geometry Need Balanced Signed and Retrievable Design Documentation (MP 10) Complete Combustion at Different Heat Loads (MP 11) o Likely Need for Full Height versus Scaled Height o Adaptability at Reduced Power Operations Cooling and Exhaust Capture Effectiveness Over Range of Operating and Accident Conditions (MP 13, 17) o Passive versus Active Component Needs o Heat Transfer Characteristics o Adaptability of Testing Configurations (e.g., modular change-outs). o Assuring Impacts of High Velocity Objects Not a Concern .6
Scaling Feedback Design Initial Design (MP 10) Adaptable Subscale Facility Design Considering A-3 CONOPS and Specification Preparation Scaling Geometry Importance. Identification of T/H Processes and Where Scaling Will Not Support Testing Demonstration Needs (i.e., Full Scale Required) Proof of Concept (MP 11) Demonstration of Effectiveness of Hydrogen Wave Heater Requiring Adjustments to both A-3 and E-3 Facilities Finalizing Procedures for Startup, Full Power Operation, and Shutdown Licensing Tests (MP 13 and 17) Demonstration of response to Design Basis Events Demonstration of Debris Capture .7
