RCS DRAINDOWN OPERATOR TRAINING U. S. Nuclear Regulatory Commission Document Control Desk Washington, D. C. 20555 Attn: Mr. J. B. Martin August 9, 1994

Dear Mr. Martin:

This letter is in response to an unresolved item identified in Inspection Report 50-315/94004(DRP). The inspection report was written about an event which occurred on February 17 and 18, 1994, during draining of the Unit 1 reactor coolant system in preparation for refueling. The unresolved item (50-315/94004-03(DRP)) is regarding training operators for infrequently performed plant evolutions (in particular, the reactor coolant syst: em draining evolution as performed via procedure ~1-OHP 4021.002.005.) Our response to the unresolved item is contained in the attachment to this letter.

In addition, we take this opportunity to correct an apparent misinterpretation reflected in Inspection Report 50-315/94004(DRP). The third item in a list in Section 7, Page 12, "Licensee Immediate Corrective Actions," reads:

"A'dministrative controls for reactor coolant system operation at 'reduced inventory'ill be reviewed against lessons learned from this event and will be continuously reviewed against industry operating experience information."

The wording of the corrective action, as provided to the inspector at the exit meeting, was:

"Administrative controls governing reactor coolant system operation at 'reduced inventory'evels will be reviewed against lessons learned from the February 17-18 reactor coolant system indication/inventory event and will be rereviewed against industry operating experience information."

The intent of the corrective action was to "review again," i.e.,

to perform a single additional review; commit to continuous or multiple reviews.

QS ATTACHMENT TO AEP: NRC: 1212A1 REPLY TO UNRESOLVED ITEM 50-315/94004-03

ATTACHMENT TO AEP:NRC:1212A1 Page 1 Inspection Report 50-315/94004(DRP) documents the conclusions of a special inspection performed in response to reactor level perturbations that occurred on February 17 anZ 18, 1994, during draining of the Unit 1 reactor coolant system. Section 5(b) of the report, entl.tied "Training,"

addresses reactor coolant system pressure, air eductor installation, reactor coolant system venting, loss of level indication, inventory draining, and the associated operator knowledge and actions. The third paragraph of this section establishes the inspectors'oncern with regard to operator training and .identifies the concern as an unresolved item.

Although the unresolved item is worded in generic terms, it was confirmed with one of the inspectors that the unresolved item is directed at the reactor coolant system draining evolution in particular. With regard to any potential generic concerns, guidance for training of infrequently performed evolutions is provided in PMI-4090. Operators were re-trained on PMI-4090 during the March 28 to May 6, 1994, training cycle.

Operation training was scheduled to strengthen operator knowledge of the reactor coolant system draining process, the associated procedure, instrumentation and system characteristics, and the difficulties experienced during the Unit 1 reactor coolant system draining activities.

A completion date of August 1, 1994, was originally scheduled to allow training of all operating crews prior to the commencement of the Unit 2 refueling outage. On April 19, 1994, however, Unit 1 was emerging from a refueling outage when a "motor differential trip" signal of reactor coolant pump ¹13 was received. It was determined that the Unit 1 reactor coolant 'system would have to be partially drained to facilitate repairs to the coolant pump. To support this activity, the planned operator training was provided ahead of schedule; between April 22 and April 27, 1994, all operating crews received this training.

The lesson plan has since been updated (Revision 1) to incorporate additional information about equipment and procedure changes, and is being presented again in operator requalification training, preparatory to the draindown evolutions in the upcoming Unit 2 refueling outage. This training is currently underway and is scheduled to be presented to all operating crews by September 9, 1994. Lesson Plan RQ-C-02Pl, "Draining RCS to Half Loop," provides training on:

(1) the August 5, 1993, RCS draining event documented in Condition Report CR-93-1267;,

(2) the February 17 and 18, 1994, RCS draining event documented in Condition Report CR-94-0281; (3) reactor vessel level indication, the importance of pressure interconnections, and the effect of valve operations on indicated and actual level; (4) steam generator tube drainage; (5) recent changes to the RCS draining procedure and the reasons for them; and (6) potential problems with alternate level indications.

We currently plan to incorporate this training in the replacement training program for new licensed operators.
