| |
| : a. On August 29, 1986, an exit meeting was held. The following personnel were present at this meeting:
| |
| K. Gerlinri, PWR Operations Training- Supervisor, Production Training Center R. E. Querio, Ryron Station Manager T. K. Higgins, Byren Training . Supervisor R. Pleniewicz,- Production Superintendent T. Petelle, Simulator Instructor, Production Training Center S. Shankman, Operator Licensing. Branch, NRC Headquarters F. Jaggar, INEL - Chief Examiner B. Picker, INEL Examiner
| |
| : b. The following generic weaknesses of the candidates were discussed by the Chief Examiner with the utility:
| |
| (1) Difficulty finding procedural requirements for sampling when blowdown or air ejector monitors are 00S.
| |
| (2) Need to supply logic diagrams for control room personnel.
| |
| (3). Noted uncertainty in locating power supplies for NI channels.
| |
| (4) When a candidate asks a question of the reactor operator on -
| |
| watch, (with examiner's approval) the reactor operator should give a complete and accurate answer.

| ', ATTACHMENT BYRON SENIOR REACTOR FACILITY REVIEW COMMENTS QUESTION 5.15 Explain why a dropped control rod is worth approximately 200 pcm and a stuck cod is worth 1000 pcm even though the same rod could be considered '
| |
| in both cases. (Assume no trip.)
| |
| NRC answer:' When a rod is stuck out with all other rods inserted, the flux profile is higher where the rod is out, therefore, that rod " sees" a much higher flux than average core flux.
| |
| (Because rod worth is a function of the relative flux difference between the rod and the core average flux, the rod is worth more (about 1000 pcm). (1.0)
| |
| If a rod is dropped just the opposite happens. The rod depresses the the flux in the area near the rod relative to the average core flux. (Worth about 200 pcm). (1.0)
| |
| Comment: The question states " Assume no trip". The answer assumes a trip. Replace key with:
| |
| Rod worth is dependent upon the relative flux the rod sees.
| |
| With the rod stuck out it sees a high flux in comparison to a dropped rod, which would depress the flux in its vicinity.

| |
| CBCo answer:
| |
| Because of the higher recirculation flow in U-2 S/G's, the level span was compressed to prevent level indication fluctuations that might occur as the recirculation flow increased with power.

| |
| : 3. Rod is declared inoperable and
| |
| : a. Tech Spec SDM satisfied,
| |
| : b. Power reduced to < = 75%
| |
| CECO answer: The question is misleading by mentioning the one hour requirement. In addition, it does not restrict the examinee to Tech Spec. IBOA ROD-4 also supplies actions to be taken I
| |
| and should be included in the key.
| |
| : 1. Calculate the QPTR, if greater than 1.02, apply Tech Spec 3.2.4

The items the facility desires, have no time limit associated with them for per-formance (according to procedure 180A R00-4).

| ANSWER 5.15 (2.00)
| |
| When a rod is stuck out with all other rods inserted, the flux e profile is higher where the rod is out, therefore, that rod "se's" a much higher flux than average core flux. (Because rod worth is a function of the relative flux difference between the rod and the core average flux, the rod is worth more (about 1000 pcm)). [1.0]
| |
| If a rod is dropped just the opposite happens. .The rod depresses the the flux in the area near the rod relative to the average core flux.

| (Worth about 200 pcm). [1.0]
