2NDIIALF1989 SEMI ANNUALREPORT l
Therefore,y statistical increase in off-site radiation doses attributable to on-site so indicate an j
no increase in the off-site calculated doses is attributable to the direct exposure from on site sources. A more detailed evaluation will be reported in the Annual Radiological Environmental Monitoring Report.
I C Solid Waste Rerort Requirements i
During the second half of 1989, the types of radioactive solid waste shipped from Calvert Clif fs were radioactive resin, which was dewatered and shipped in high integrity containers, 4
and dry compressible waste, which was shipped as LSA waste in strong, tight containers.
Table 3A summarizes the waste shipment data. Also, Appendix A provides a detailed breakdown of the waste shipments for 1989 per the categones as specificied in Technical Specification 6.9.1.8.
J D. ODCM and PCP Chm 1gg Two changes were made to the ODCM during the calendar year 1989. Each change was reviewed by POSRC and approved by the Manager, Calvert Cliffs Nuclear Power Plant, pilor to implementation. The scope and basis for these changes are discussed in Appendix B. In keeping with the requirements of the Technical Specification 6.17, a copy of the -
changes to the CCNPP ODCM are enclosed in Attachment 1. Vertical lines in the right margin of the text denote the above referenced changes with accompanying change number.
No changes were made in the PCP in the second half of 1989.

Radioactive Gaseous Effluent Monitorine Instrumentation
)
The Unit 1 and 2 Steam Generator Blowdown RMS effluent monitors (1 RE-4014 and 2-
}
~
RE 4014) were out of service for greater than thirty days. These notifications are required by Technical Specifciation 3.3.3.10. The Unit 2 blowdown monitor was declared inoperable on August 26,1989, and the Unit 1 blowdown monitor was declared inoperable on August 27, 1989 Both monitors were out of service for outage related maintenance which prevented completion of source checks in accordance with Surveillance Test Procedures 01021 and 0-102-2. During this period of time no releases were made via this pathway.

Fission and Activation Gases 1.
Batch Releases Prior to each batch release of gas from a pressurized gas decay tank, a sample is -
1 collected and analyzed 17 gamma spectroscepy using a Ge detector for the principal t
- gamma emitting noble gas radionuclides. The total activity released is based on the pressure / volume relationship (gas laws) of the tank.
~
j{
Prior to and after each containment purge, a gas sample is collected and analyzed by -
gamma spectroscopy using a Ge detector for the principal gamma emitting noble gas radionuclides. The total activity released is based on containment volume and purge t
rate. Activity buildup while purging is also considered.
