ABSTRACT (Limit to 1400 spaces. i.e.. approximately fifteen single-space typewritten lines) (16) hl NO SUBMISSION DATE (15)

I I I On July 14, 1988 at 1245 hours0.0144 days <br />0.346 hours <br />0.00206 weeks <br />4.737225e-4 months <br />, with Unit 1 at lOE-7 amp intermediate range and Unit 2 at 100% power, it was determined the Technical Specification that required sampling had not been performed within the required time frame. Technical Specification Table 3.7-S(a) requires that the service water side of the component cooling (CC) water heat exchangers (EIIS-HX) be sampled and analyzed for radioactive contamination every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Due to an error made by the technician performing the analysis, one sample for the "B" and "C" CC heat exchangers was discarded without the proper analysis being performed.

This resulted in the samples being performed approximately 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> apart. Radiation levels of samples prior to and following the missed samples were within specified limits.

Samples of the "B" and "C" heat exchanger service water were immediately obtained and analyzed. The analysis of samples were found to be.within acceptable limits. Personnel were reinstructed in the importance of thorough analysis.

Technical Specification Table 3.7-5(a) requires that the service water (SW) side of the component cooling (CC) water heat exchangers (EIIS-HX) be sampled.and analyzed for radioactive contamination every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Due to* an error made by the technician performing the analysis, one sample for the "B" and "C" CC heat exchangers was discarded without the proper analysis being performed. This resulted in the samples being performed approximately 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> apart. Radiation l~vels of samples prior to and following the missed samples were within specified limits.

2.0 Safety Consequences and Implications The component ' cooling system is an intermediate cooling system which serves both reactor units. It transfers heat from heat-exchangers containing reactor coolant, other radioactive liquids, and other fluids to the service water system.

Since there was no increase in the circulation water discharge radiation monitor (indication of CC to SW tube integrity) during this event, the health and safety of the public were not affected.

3.0 .Cause The service water contamination analysis procedure consists of three steps: (1) place sample in dete~tor, (2) erase old data/

start new data acquisition, and*(3) perform analysis on new data.

In this event, the technician performing the procedure neglected to perform step 2. Step 3 was therefore performed on old data and proper analysis of the new samples was not obtained.

4.0 .Immediate Corrective Action(s)

Samples of the "B" and "C" heat exchanger service water were immediately obtained and analyzed. The analysis of samples were found to be within acceptable limits.

5.0 Additional Corrective Action(s)
