SUBJECT:
Limerick 2 Cycle 5 RWE Analysis
Dear Hugh:
This letter provides the information requested by the NRC on January 24,1997, regarding the Limerick 2 Cycle 5 Rod Withdrawal Error (RWE) analysis. A cycle specific RWE analysis i
wu performed for Limerick 2 Cycle 5 as part of the reload licensing. The results demonstrate that the 1% cladding plastic strain criterion was met. Limerick 2 Cycle 5 passed the check for the 1% cladding plastic strain criterion for full withdrawal of any control rod.
Additionally, the current Rod Block hionitor (RBht) operability requirements (Technical Specifications Section 3 / 4.1.4.3) are adequate to protect against Safety Limit violations and 1% cladding plastic strain for Limerick 2 Cycle 5. In the Limerick 2 Cycle 5 RWE analysis, the control tod was fully withdrawn without violation of the 1% plastic strain criterion, therefore, htCPR is the limiting parameter for setting the RBhi operability conditions.
Please contact me if you have any questions.
Very truly yours,
^
