Subject:
CEOG Task 931 Survey Questionnaire-CEA Insertion Experience with High Burnup Fuel Management The purpose of this le"?r is to transmit a questionnaire developed under CEOG Task 931. CEOG Te V 31 has been designed to allow the CEOG to proactively address NRC Bulletin
- 01. NRC Bulletin 96-01 was irecently ssued based upon control rod insertiu problems in higher bumup fuel assemblies at several Westinghouse PWR units. Although formal action is required only from PWR licensees of Westinghouse units, the NRC requested in a March 27,1996 meeting that CEOG and B&WOG proactively respond to the issues of the Bulletin. CEOG Task 931 has been authorized to provide a formal response through the development of a CEA insertion experience data base for all CE plant designs and a technical report on this issue for CEOG member use and reference. The questions in this survey are intended to produce a comprehensive CEA insertion experience data base.
The Analysis Subcommittee member is requested to coordinate the response to the enclosed questionnaire. Additionally, the Analysis Subcommittee member is requested to provide the name and telephone number of a technical point of contact for this task to the Task Leader listed below. Resoonses to the auestionnaire are reauested bv Aoril 15.1996.

Attrchm::nt to CEOG-96-116 Questionnaire-CEA Insertion Experience with High Burnup Fuel Management Questions:
1.
Provide copies of any Licensing Event Reports (LERs) written on CEA operability issues within the last 10 years, including any problem related to slow CEA insertions, restricted CEA insertions or failure of CEAs to fully insert.
Indicate the type of CEA affected (e.g., shutdown, part length). Wrthin this same time period, have rod bottom lights ever failed to light after a reactor trip or during rod drop testing?
2.
Provide copies of any root cause analyses performed related to CEA operability issues in Question 1.
3.
Have CEAs ever been noted to be stuck within fuel assemblies or difficult to withdraw or insert during refueling or maintenance operations within 2
containment or at the spent fuel pool, where LERs were not required? Provide details of each event.
4.
Provide CEA drop time test data obtained over a minimum of the last five years (four or more cycles), including reactor cycle number, time in cycle, drop time by CEA, type of CEA and raw data if available. Provide average bumup of each assembly under a CEA for each such test. Indicate when replacement CEAs are first used.
5.
Provide CEA scram data obtained over a minimum of the last five years (four or more cycles), including reactor cycle number, time in cycle, scram time by CEA, type of CEA and raw data if available. Provide average burnup of each assembly under a CEA for each scram experienced.
6.
Has your review of drop time test data or scram data indicated that these data may provide precursor information relative to CEAs sticking within guide tube or dashpot region (e.g., such as the lack of rod recoil observed in traces for Westinghouse control rods at higher bumup)?
7.
Have you ever performed CEA drag tests at any of your CE units? If so, please provide results.
8.
Have you performed visual (e.g., boroscopic) inspections of guide tube inner diameter wall within the last 10 years? If so, please provide results.

Hava indications cycr been documented of unusual crud or corrosion buildup on interior walls of guide tubes or dashpot regions? Have these deposits been tied to a change in CEA insertion times? Please provide details.
10.
Excessive fuel assembly distortions (e.g., abnormal bow and twist) have been suggested as a possible contributing factor to stuck Westinghouse control rods. Has fuel assembly distortion been noted to be any more severe in higher bumup fuel assemblies such that unusual handling situations result? Please provide specific details of any event.
11.
What suggestions do you have for reasonably obtaining supplemental operating data that assures acceptable CEA operability on a continuing basis?
In particular, what are important considerations (pros and cons) for performing a rod drop test from low power at EOC and/or CEA drag testing in higher bumup discharged fuel assemblies?
