At approximately 1214 MST on March 23, 1987, Palo Verde Unit 1 was in Mode 1 (POtltER OPERATION) at 100 percent power when a review of the spectrum analysis results for the daily grab samples required by Technical Specifications 3.11.1.1, Table 4.11-1, revealed that three grab samples had not been analyzed. At approximately 0830 HST on March 20, 1987, the turbine building sump sample and the condenser area sump samples were drawn. A chemistry technician delivered the samples to the Unit 2 counting lab for analysis due to the inoperability of the Unit 1 analysis equipment. The unanalyzed samples were apparently placed with samples that had-already been analyzed. The turbine building sump sample and condenser area sump samples were not analyzed.

The root cause of this event was a cognitive personnel error by the Unit 1 chemistry technician (utility non-licensed) in that he did not ensure that the Unit 1 samples were analyzed. As corrective action the responsible individual received appropriate disciplinary action. Additionally, this event was discussed with Unit 1 Chemistry personnel,.

No similar events have been reported.

akWoW /YRC Form JOSA'Fl 1171 0 5 0 0 0 5 8 7 004 00 02 OF 0 2 At approximately 1214 MST on March 23, 1987, Palo Verde Unit 1 was in Mode 1 (POWER OPERATION) at 100 percent power when a review of the spectrum analysis results by a chemistry technician (utility non-licensed) for the daily grab samples required by Technical Specifications (T.S.) 3.11.1.1, Table 4.11-1, revealed that three grab samples had not been analyzed. The unanalyzed samples were the turbine building (NM) sample and two (2) condenser area sump samples. These samples were drawn at approximately 0830 MST on March 20, 1987. The review on March 23, 1987, showed that the samples were correctly taken and analyzed at the next scheduled frequency on March 21, 1987. Analysis results were within T.S. limits. The event lasted approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Prior to this event, all grab samples drawn in Unit 1 were being sent to Unit 2 for analysis due to the inoperability of the Unit 1 counting equipment.

At approximately 0830 MST on March 20, 1987, the turbine building sump sample and the condenser area sump samples were drawn. A chemistry technician (utility non-licensed) delivered the samples to the Unit 2 counting lab for analysis.

The unanalyzed samples were apparently placed with samples that had already been analyzed. The turbine building sump sample and condenser area sump samples were subsequently overlooked and not analyzed.

The root cause of this event was a cognitive personnel error by the Unit 1 chemistry technician (utility non-licensed) in that he did not ensure that the Unit 1 samples were analyzed. Not analyzing samples required by T.S. is contrary to approved Administrative Control procedures. As corrective action the responsible individual received appropriate disciplinary action.

To prevent recurrence a briefing session was held with the Unit 1 chemistry technicians explaining the event and reminding the technicians of their responsibility to meet Technical Specification requirements. Additionally, this event will be discussed with Unit 2 and 3 technicians. As an aid to the chemistry technicians, a "Current Chemistry Technical Specification Action Statement" form was developed. This form will be prepared daily and will contain information as to what samples are required and when they need to be taken to meet the appropriate Technical Specification Action statements. The form will also list when samples were taken and when sample analysi's was completed.

There were no unusual characteristics of the work location which contributed to this event. There were no automatic or manual safety system responses.

There were no structures, systems or components inoperable, prior to the event, other than described above, which contributed to the event. There were no operator actions which contributed to this event.

A review of the results of the grab samples taken prior to and following the unanalyzed samples showed all were within the release limits specified in T.S.

3.11.1.1. There is no indication that the release limits specified in T.S.

3.11.1.1 were exceeded. This event did not affect the safe operation of the plant or the health and safety of" the public.

No similar events have been reported.
