i y 1.0 Introduction Dresden Nuclear Power Station is a three reactor generating facility owned and operated by the Conanonwealtb Edison Company of Chicago, Illinois.
Dresden Station is located at the confluence of the Kankakee and Des Plaines Rivers, in Grundy County, near Morris, Illinois.
Dresden Unit 1 is a General Electric Boiling Water Reactor with a design net electrical output rating of 200 megawatts electrical (MWe). The unit is retired in place with all nuclear fuel removed from the reactor vessel.
Therefore, no Unit 1 operating data is provided in this report.
Dresden Units 2 and 3 are General Electric Boiling Water Reactors with design net electrical output ratings of 794 MWe each.
Waste heat is rejected to a man-made cooling lake using the Kankakee River for make-up and the Illinois River f or blowdown.
The Architect-Engineer for Dresden Units 2 and 3 was Sargent and Lundy of Chicago, Illinois.
This report for June, 1991 was compiled by Donald C. Maxwell of the Dresden Technical Staff, telephone number (815)942-2920 extension 2489.

i 2.0 EUtttRLDEEEEAUH9_EXtERIENZ_E2A.llE,_1921 2.1 UNIT 2 MONTilLY OPEPATING EXPERIENCE StM1ARY 06-01-91 to 06-10-91 Unit 2 entered the month on-line and cperating in the RUN mode at 684 MWe, The unit operated until 0301 hours0.00348 days <br />0.0836 hours <br />4.976852e-4 weeks <br />1.145305e-4 months <br /> on 6-9-91, when an automatic main turbine trip occurred. The cause of the turbine trip was a thrust bearing wear detector malfunction. The turbine trip was followed by a reactor scram on high reactor pressure at 0302 hours0.0035 days <br />0.0839 hours <br />4.993386e-4 weeks <br />1.14911e-4 months <br />. The Reactor scram was caused by increasing pressure due to loss of feedwater heating.
06-11-91 to 06-30-91 After completion of the scram investigation and inmediate corrective actions, the Reactor was made critical on 6-11-91 at 0020 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> and the Generator was synchronized to the system at 1108 hours0.0128 days <br />0.308 hours <br />0.00183 weeks <br />4.21594e-4 months <br /> of the same day.
The unit operated through the end of the month with an availability of 92.21% and a capacity factor of 58.23 %.
On the af ternoon of 6-21-91, the Dresden Unit 2/3 discharge canal temperature recorder was approaching administrative limits for blowdown water temperature. To prevent a violation of Dresden Station's Environmental Protection Agency (EPA) permit requirements for blowdown temperature, the Dresden Cooling lake spillway gates were closed in order to isolate the hot lake water from the 1111nois River.
Dresden's mode of operation was then switched at the lake flow regulating station from indirect open cycle to closed cycle operation with 50,000 gpm blowdown. A subsequent load drop was taken on both units for three main reasons: 1) To allow enough margin in condenser vacuum to run on two circulating water pumps per unit in order to limit flow input into the lake.
- 2) To allow enough margin in condenser vacuum to operate the units with the inticssed circulating water inlet temperature.
- 3) To limit the heat input into the lake in order to reduce future blowdown temperatures.
On 6-22-91, lake temperatures were sufficiently reduced and indirect open cycle operation was resumed.

SUMMARY
06-01-91 to 06-30-91 Unit 3 entered the month on-line, in the RUN mede and operating at 459 MWe.
The unit operated the entire month in normal fuel.
depletion mode with an availability of 100.01 and a capacity factor of 54.20%.
On the afternoon of 6-21-91, the Dresden Unit 2/3 discharge canal temperature recorder was approaching administrative limits for blowdown water temperature. To prevent a violation of Dresden Station's EPA permit requirements for blowdown temperature, the Dresden Cooling Lake spillway gates were closed in order to isolate the hot lake water from the lilinois River.
Dresden's mode of operation was then switched at the lake flow regulating station irom indirect open cycle to closed cycle operation with 50,000 spm blowdown. A subsequent load drop was taken on both units for three main reasons: 1) To allcw enough margin in condenser vacuum to run on two circulating water pumps per unit in order to limit flow input into the lake.
- 2) To allow enough margin in condenser vacuum to operate the units with the increased circulating water inlet temperature.
- 3) To limit the heat input into the lake in order to reduce future blowdown temperatures. On 6-22-91, lake temperatures were sufficiently reduced and indirect open cycle operation was resumed.

s ZR18/1463/13 i
l l _'. _. _.
lc CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL Changes to the Offsite Dose Calculation Manual (00CH) are reportable to the Nuclear Regulatory Commission (NRC) in accordance with station Technical Specifications. This document contains the models for the public dose assessment from gaseous effluents, liquid discharges, and direct radiation.
The NRC, per Generic Letter 89-01, requested that the information found in the station Radiological Effluent Technical Specifications to be transferred to the 00CH and Process Control Program (PCP), as applicable. The major changes to the ODCH complied with this request. The remaining minor changes were editorial, outstanding from the previous distribution, Revision 0, dated March, 1989.
This revision does not reduce the accuracy and reliability of dose calculations or set point determination methodology.
Any changes to the OOCH computer program required by this document are in the process of being implemented now and should be fully available by July 8, 1991.
MAJOR CHANGES The generic manual both introduces and references the Radiological Effluent Technical Specifications contained in the site annexes, in Chapter 12, now titled the " Radiological Effluent Techu1 cal Standards (RETS)".
" Operability Requirements" in the RETS are equivalent to Limiting Conditions for Operations in the station Technical Specifications.
The generic manual is common for six sites, therefore the reporting requirement for " Changes to the 00CH" deviates slightly from the recommendation given in the Generic Letter. An effective date for generic manual implementation is to specified in the station Onsite Review. As in the past, the official transmittal to the NRC is made through the stations' Monthly Operating Report within 90 days of the effective date.
HINOR OIANGES The remaining minor changes are editorial.
Below is the abbreviated version of an itemized list of changes available in Emergency Preparedness in at the Corporate Office:
Revised titles for the Corporate Offie e Department and Positions Prepared a stand alone section for the EPA's Clean Air Act (if and when enacted)
Deleted references to Commonwealth Edison (or CECO)
Added text regarding the Hilmington Public Hater Supply nearby Braidwood Station Corrected parameter symbols, values and units.

The NRC requires that the statiorm' Radiological Effluent Technical Specificatione, formally a subset of the Technical Spectrications, shall be incorporated into the.ODCM (see Reference 80). A Radiological Effluent Technical Standards (RETS) section for each station is found in the site specific annexes in Chapter 12.

Section 1.2.3 1-5 Deletion The bold text was inserted and the barred text was deleted.
Compliance with the dose limits in the RETS is determined pnmarily by calculations based on measurements or radioactuity in stations effluents.
The RE33 Technical Specifications requred each station to have a documeilt called the Offsite Dose Calculation Manual (ODCM) to provide the methodology and parameters for these t ah dation. h?._W h r".^d W ^" ~~M

The major categories of items in RETS are the following:
- Definitions A glossary of terms found in but are not limited to the ODCM.
- Instrumentation This section states the Operablitty Requirements (OR) for Instrumentation performance as well as the associated Survelliance Requ'.tenents. These conservatNe alarm / trip setpoints ensure the regulatory compilance for both liquid and gaseous effluents. Survelliance Requirements are listed to ensure ors are met through testing, calibration, inspection and calculation. Also !ncluded for such categories are the Esses for interpreting the requirements.
The Operability Requirement or an OR is the ODCM equivalent of a Umiting Condition for Operation as defined ha both the Standard Radiological Effluent Technical Specifications and the stationa' Technical Specifications.
- Uquid Eff!uerf.s This section addresses the Ilmits, special reports and liquid waste treatment systems required to substantiate the dose due to liquid radioactMty concentrations to unrestricted areas. Survelliance Requirements and Bases exist for liqu'd effluents.
