Denotes those present at the exit interview on March 12, 1993. Other licensee
employees were contacted and interviewed during this inspection.
-t 2.0 Pumose
,
The purpose of this inspection was to myiew the licensee's ability to control and quantify effluent radioactive liquids and gases, and particulates during normal and
,
emergency operations.
,
3.0 Management Controls 3.1 Program Changes
'
The inspector myiewed the organization and administration of the radioactive i
liquid and gaseous effluent control pmgrams and discussed with the licensee
'
changes made since the last inspection, conducted on Febmary 3-7,1992. The inspector determined that there were no changes to the radioactive effluent control pmgrams. However, the inspector noted that the total number of
,
i
.
..
employees of the Chemistry Depanment will be 55, increased by 6, in the near future.
3.2 Audit The inspector reviewed the 1992 Quality Services Depanment (QSD) Audit'
Repon Number A24030. This audit was conducted by the QSD and covered the radioactive liquid and gaseous ef0uent contml programs. The inspector noted that the audit was conducted by members of the Assessment Services Depanment with assistance from other technical personnel. The audit covered the stated objectives and was thomugh and of good technical depth. The audit identified no findings, but contained four recommendations to enhance the
cf0uent contml programs. Even though a response to the recommendations
was not required, the responsible Depanment addressed two of the f
recommendations. Two other recommendations will be implemented by
March 1993. The inspector stated that the scope and technical depth of the
{
audit were excellent to assess the radioactive liquid and gaseous ef0uent
!
control programs.
l l
3.3 Review of Semiannual Radioactive Ef0uent Renons The inspector reviewed the semiannual radioactive effluent release repons for l
the second part of 1991, the first pan of 1992, and the raw data for the second
pan of 1992. These repons pmvided total released radioactivity for liquid and
!
gaseous effluents. The inspector also reviewed the annual radioactive efnuents
!
dose repon for 1991. This annual radioactive effluents dose repon pmvided a j
summary of the assessment of the maximum individual and population dose resulting from routine radioactive airborne and liquid ef0uents. The inspector determined that the licensee met the Technical Specification reponing
requirements. The inspector determined that there were no obvious anomalous
[
measurements, omissions or trends in these reports.
,
!
4.0 Radioactive Liquid and Gaseous Ef0uent Control Pmgrams
!
The inspector reviewed the following licensee procedures and radioactive liquid and
gaseous discharge permits to determine the implementation of the Technical Specification and the Offsite Dose Calculation Manual requirements for all Units.
l
!
o CP-2809B, Liquid Waste Discharge (Unit 2)
i o
CP-2809C, Gaseous Discharge (Unit 2)
o CP-3806A, Liquid Waste Discharge (Unit 3)
!
CP-3806J, Effluent Report Preparation (Unit 3)
o o
CP-3806AU, Sampling Inoperable Radiation Monitors (Unit 3)
!
i
e
.
The inspector also discussed with the licensee various aspects of the effluent control programs, such as communication with Radwaste Operations. The inspector detennined that the ef0uent contml procedures (CP-2809B, CP-2809C, and CP-3806A) were sufficiently detailed to allow performance of all necessary steps. The
'
inspector also determined that the reviewed discharge pennits were completed and
,
met the Technical Specification requirements for sampling and analyses at the frequencies and lower limit of detections established in the Technical Specifications.
During the review of the Unit I gaseous efduent contful program, the inspector noted
'
that both recombiners were out of service due to steam leaks from February 27,1993 to March 5,1993. The Chemistry Department sampled and analyzed a grab sample
,
daily during the out of senice period. The licensee performed dose assessment daily.
!
The total gamma and beta air doses during the out of service period were 0.021 and.
0.0021 mrad, respectively, which were insignificant.
.;
During discussion with the Chemistry Department staff of all three units, the inspector i
noted that the responsible individuals had excellent knowledge in the areas of: (1)
radioactive liquid and gaseous effluent controls, (2) efnuent/ process Radiation Monitoring Systems (RMS), (3) quantifying the total amount of liquid and gaseous
effluent release using the RMS, (4) protection of the public health and safety and the environment, and (5) the Offsite Dose Calculation Manual requirements.
!
Based on the above reviews, the inspector determined that the licensee had conducted effective radioactive liquid and gaseous efauent control programs.
5.0 Calibration of Efduent/ Process Radiation Monitors l
The inspector reviewed the licensee's most recent calibration results for the following leffluent/ process radiation monitors to determine the implementation of the Technical
,
Specification requirements for Units 1,2, and 3.
i Unit 1:
o Radwaste Efduent Radiation Monitor o Service Water Effluent Radiation Monitor o Reactor Building Closed Cooling Water Radiation Monitor o Air Ejector Offgas Radiation Monitors
'
o Stack Gas Radiation Monitor
o Stack High Range Radiation Monitor t
Unit 2:
o Stack Gaseous Process Radiation Monitor
'
o Steam Jet Air Ejector Radiation Monitor i
o Steam Generator Blowdown Line Monitors
o Clean Liquid Radwaste Monitor j
o Aerated Liquid Radwaste Process Radiation Monitor

Unit 3:
o Liquid Radwaste Radiation hionitor
'
o Main Steam Line Afonitors o Turbine Building Floor Drain Monitor o Turbine Building Vent Monitor i
o Engineered Safeguards Building Gaseous Radiation Monitor
,
o Steam Generator Blowdown Radiation Monitor
!
The I&C Department had the responsibility to perform electronic and mdiological calibations for the above radiation monitors with the exception of the Unit 1-l Radwaste Effluent, Service Water, Reactor Building Closed Cooling Water, and Stack Gas Effluent Radiation Monitors. The Unit 1 Chemistry Section performed the l
radiological calibration for these radiation monitors. All reviewed calibration results
'
were within the licensee's acceptance criteria.
j
!
During the review of the above calibration results, the inspector independently
[
verified several calibration results including linearity tests and conversion factors.
Using the licensee's raw data, the inspector performed statistical analyses (linear i
regression) for comparison. The inspector determined that these independent
comparisons were excellent.
!
i Based on the above review, the inspector determined that the licensee was
!
implementing Technical Specification requirements effectively.
1 6.0 Air Cleanine Systems
The inspector reviewed the licensee's most recent surveillance test results to
determine the implementation of the following air cleaning systems for Units 1,2, and 3. The surveillance tests for these air cleaning systems were required by the
,
Technical Specifications.
!
i
'
i Unit 1:
o Standby Gas Treatment System

o Secondary Containment Enclosure Building Filtration System i
o Control Room Emergency Ventilation System o Fuel Storage Pool Area Ventilation System
