Comment Resolution 1
S3, without seeing the JPM, it is unlikely that simply loading a diesel onto a bus will qualify as an (EN) JPM Although the title of the JPM states to manually start an ESF DG the initial conditions do not tell the operator why the ESF Bus has not re-energized. In other words the operator is not simple being told to start an ESF DG. (The bus did not re-energize because the engineered safety features actuation signal failed because the ESF DG Sequencer lost power which is unknown to the operator.) The operator has to determine the condition of the ESF Bus, that the ESF DG failed to auto start and determine that the ESF DG can be manually started to supply the ESF Bus.
Simulator Scenario Outline Comments (Date)
Comment Resolution 1
Scenario 1 is the only scenario that has entry into a contingency EOP, therefore all operators MUST run scenario 1. In addition, there is a risk associated with not having a spare with entry into a contingency EOP, in the event scenario 1 is lost.
We have an idea to add an event at an opportune time after the reactor trip in Scenario #3 that would have the crew transition to the EC procedure for LOCA outside the RCB to address this concern.
2 Scenario 1, CT#1 needs bounding criteria We include the bounding information for all CTs with the Scenario details. To address
OBDI 202 - IOLE Process Rev 3 the concern we will also include the bounding information with the outline when we submit the DRAFT Exam material.
3 Scenario 2, CT#2 needs bounding criteria We include the bounding information for all CTs with the Scenario details. To address the concern we will also include the bounding information with the outline when we submit the DRAFT Exam material.
4 Scenario 3, CT#2. Question: Is the critical task success to trip all RCPs prior to Orange Path on core cooling?
YES We include the bounding information for all CTs with the Scenario details. To address the concern we will also include the bounding information with the outline when we submit the DRAFT Exam material.
