1.0 INTRODUCTION

The following constitutes Part l I of the final report for the 2019 Radiological Monitoring **

Program conducted at the Kewaunee Power Station (KPS), Kewaunee, Wisconsin.

Included are tabulations of data for all samples collected in 2019 along with graphs of data trends. A summary and interpretation of the data presented here are published in Part I of the 2019 Annual Report on the Radiological Monitoring Program for the Kewaunee Power Station.

- 2.0 GRAPHS OF DATA TRENDS

- Note: Conventions used in trending data.

The following conventions should be used in the interpretation of the graphs of data trends:

- 1. Both solid and open data points may be used in the graphs. A solid point indicates an activity, an open point, a lower limit of detection (LLD) value.

2. Data points are connected by a solid line. A break in the plot indicates missing data.

The air sampler had operated for 109.18 hours2.083333e-4 days 0.005 hours 2.97619e-5 weeks 6.849e-6 months prior to the fuse blowing. The air sample filter was changed out and and will be sent to the vendor for analysis with a reduced sample volume for the sample week ending 4/23/19. Since this is the second consecutive week that the air sample pump at K-lf experienced a blown fuse (CR#l880), the air sampler (#6735) was removed from service and replaced with air sampler #6731 on 4/22/19. Noted the event and CR number on the environmental

- Long Description While reviewing the January* March 2019 Radiological Environmental Monitoring Program

Environmental, it was noted that the Location K*1d (condenser discharge) monthly surface water sample was not taken due to frozen conditions. In

- accordance with REMM Table 2.2.1-A, Radiological Environmental Monitoring Program, Table Notation b, "Deviations from the required sampling schedule will occur If specimens

- are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment, and other legitimate reasons." In this case the sample was unobtainable due to both hazardous weather conditions and seasonal unavailability (lake was frozen). There have been no discharges of radioactive liquid effluents since the first week of August, 2018. With the implementation of REMM Revision 22 on April 1, 2019, the required frequency for surface water sampling at K-ld and other locations has been

- Initial Actions reduced from monthly to quarterly .

Initiated CR to document missed surface water sample at location K-ld (condenser discharge)

Recom Actions:

- Recommend CA to RP to document this missed surface water sample at K-ld and include a copy of this CR In the 2019 Annual Radiological Environmental Operating Report (AREOR) per REMM 2.4.1.c .

- Initial Actions Turned pump off.. Restarted pump and did not see

- any improvement Turned pump off again

Changed out filter

Contacted system expert and informed of issue .

Noted issue on sample collection data sheet.

Recommended using a conservative sample flow rate of 15 LPM due to pump fallfng and flow indication less than normal
