The Cycle 17 reload consisted of replacing 240 Atrium 10 AREVA fuel assemblies with 240 Global Nuclear Fuel (GNF) GNF2 fuel assemblies.
No other revision to the design or operation of the station were conducted which would affect the scope of this report.The following startup tests were performed during Refueling Outage RF16 or while' attaining full power after RF16, and are summarized in this report: 1) Core Loading Verification
- 2) Control Rod Scram Time Testing 3) Shutdown Margin Determination
- 4) TIP Symmetry In addition to the above startup physics tests, the startup test program included:
Core Monitoring System Verification, and other surveillance testing required by RBS Technical Specifications.
The additional test results are available at the site on request.CORE LOADING VERIFICATION Purpose Ensure each reactor fuel assembly is:* In its correct core location* Oriented properly* Seated properly in its support piece Attachment to RBG-Page 2 of 4 Criteria The reactor core is visually checked to verify conformance to the vendor supplied core loading pattern. Fuel assembly serial numbers, orientations, and core locations are-recorded.
A height check is performed to verify all assemblies are properly seated.Results The as-loaded core was verified for proper fuel assembly serial numbers, locations, orientation and seating in accordance with the RBS Cycle 17 core loading pattern. There were no location or orientation deviations from the Cycle 17 core loading pattern.The core verification procedure was successfully completed on February 5, 2011.CONTROL ROD FUNCTIONAL TESTING Purpose Verify functionality of each control rod by:* Performing normal withdrawals and insertions
- Ensuring it is latched to its control rod drive Criteria Testing of each control rod is performed in accordance with technical specification to ensure proper operability.
This testing includes coupling verification, and scram time testing.Results All control rods were scram timed tested and coupling verified as discussed below.Fifteen (15) Control Rod Drive Mechanisms and eleven (11) Control Rod Blades were replaced during the outage. Seven (7) hydraulic control units had maintenance completed.
All maintenance related rods with the exception of 20-45 and 16-53 were scram time tested prior to startup during the vessel pressure test in accordance with TechnicalSpecification Surveillance Requirements 3.1.4.3 and 3.1.4.4 with satisfactory results. Control rod 20-45 remained inoperable
(@ position 00) and reactor power below 40% CTP until tested. Control rod 16-53 was tested at zero pressure to restore operability for the approach to critical.The remaining control rods were scram time tested during the vessel pressure test in accordance with RBS Technical Specification Surveillance Requirement 3.1.4.4 (fuel movement) with the exception of 12-45 and 04-37.Control rods 20-45, 16-53, 12-45 and 04-37 were tested and satisfactorily met the acceptance criteria prior to exceeding 40 percent rated core thermal power.
Attachment to RBG-Page 3 of 4 A control rod coupling check was performed in accordance with RBS Technical Specification Surveillance Requirement 3.1.3.5 each time a control rod was fully withdrawn.
SHUTDOWN MARGIN DETERMINATION
/ REACTIVITY ANOMALY CHECK Purpose To ensure that: The reactor can be made sub-critical from all operating conditions The reactivity transients associated with postulated accident conditions are controllable within acceptable limits The reactor will be maintained sufficiently sub-critical to preclude inadvertent critically in the shutdown condition Criteria The in-sequence rod withdrawal shutdown margin calculation begins by withdrawing control rods in their standard sequence until criticality is achieved.
The shutdown margin of the core is determined from calculations based on the critical rod pattern, the reactor period and the moderator temperature to satisfy SR 3.1.1 .1 .a.Reactivity Anomaly verification is performed in accordance with Technical Specification Surveillance Requirement 3.1.2.1 after reaching equilibrium xenon concentrations at 100%reactor power.Results The in-sequence critical shutdown margin surveillance procedure was completed on February 11, 2011. The shutdown margin (SDM) at the beginning-of-cycle (BOC) was calculated to be 0.778 % delta k/k which is bounded by RBS Technical Specification
3.1.1 requirement
of 0.38% delta k/k. Final steady state full power operation was achieved on February 23, 2011.It was verified on February 23, 2011, that no reactivity anomaly was present by performance of Technical Specification Surveillance Requirement 3.1.2.1.
Attachment to RBG-Page 4 of 4 TIP SYMMETRY CHECK Purpose To determine the reproducibility of the Traversing Incore Probe (TIP) system readings Criteria This procedure applies to BWR plants operating with Global Nuclear Fuel (GNF)reduced uncertainties safety limit Minimum Critical Power Ratio (MCPR) methodology and using 3D MONICORE version 6.58 and higher. This MCPR methodology requires that a TIP symmetry check be conducted each cycle to confirm its assumptions.
Results The TIP symmetry calculation was performed on April 4, 2011, using 3D Monicore at 100%core thermal power.The determined TIP uncertainty is 5.59% which is bounded by the acceptance criteria of 6%.
