SUBJECT:
C-E BURNABLE POISON IRRADIATION TEST PROGRAM (TACS-4514)
Report
Title:
C-E Burnablo Poison Irradiation Test Program Report Number:
CEN No. 50-P, Eev. qn Report Date August, 1977 Originating Branch LWR-2 and Proj ect Manager:
D. Tibbitts Syst, ems Safety Branch Involved:. Core Performance Branch Review Status:
Conplete The subject topical report as revised has been reviewed by the Reactor Fuels Section of the Core Perfor=ance Branch.
The revision primarily adds a Phase IV to the Combustion Engineering proposed irradiation program for burnable poison rods of the 16x16 design as described in CEN-50.
Previously, we reviewed
' Phase I, II and III of this prugram and found the proposed pro-gram acceptable (memo Ross to Vassallo dated April 20, 1977).
Phase IV of the proposed' program involves the irradiation and performance evaluation of a scall nunber of' rods with a pro-prietary poison material and of a proprietary de, sign.
Both the naterini and the design ~ described in Phase IV have been reviewed previously by NRC and approved for use in Calvert Cliffs, Unit 1 (for references, see meno of April 20, 1977).
The test rods in Calvert Cliffs were examined after a core average exposure of.
l 17,000 MWi/t and their performance was favorable.
Phase IV rod i
localions in ANO,21 have been analyzed by {C--E to be non, limiting for narmal operation or accident conditions.
On the basis of the present and previous reviews, the conf'irmatory irradiat'on results and the non-limiting locations in ANO-2, we find Phase IV of the proposed test program and CEN 50-P, Re' vision 1 acceptable.
