| Reason: The formatting of these controls is changing to follow the layout of NUREG-1302 (Offsite Dose Calculation Manual Guidance:
| |
| Standard Radiological Effluent Controls for Boiling Water Reactors, Generic Letter 89091, Supplement No. 1 ). 3. 72 25 B The Surveillance Requirement 4.11.2.6.1 is captured in the ODCM Surveillance Requirements 4.1.2. 4.11.2.6.1 The rate of the sum of the activities of noble gases at the recombiner after condenser discharge shall be continuously monitored in accordance with Specification 3.3.7.12.
| |
| ODCM 4.1.2 Each radioactive gaseous effluent monitoring instrumentation channel shall be demonstrated OPERABLE by performance of the CHANNELCHECK,SOURCECHECK,CHANNEL CALIBRATION, AND CHANNEL FUNCTIONAL TEST operations at the frequencies shown in Table 4.1-2. Reason: The formatting of these controls is changing to follow the layout of NUREG-1302 (Offsite Dose Calculation Manual Guidance:
| |
| Standard Radiological Effluent Controls for Boiling Water Reactors, Generic Letter 89091, Supplement No. 1 ). There is no change to the surveillance frequency'or monitoring requirements.
| |
| : 4. 69 28 B Changed the Action response for when the minimum channels requirement in Table 3.3.7.12-1 for the Main condenser Offgas Pre-Treatment Radioactivity Monitory cannot be met, removing the 72 hour shutdown statement and adding additional sampling requirements.
| |
| New action statement requires the following:
| |
| : a. The North Stack Effluent Noble Gas Activity Monitor requirements of Table 3.1-2 are met and b. Grab samples are taken once per 24 hours and isotopic analysis is performed within 4 hours of sample time to verify that the noble gas gross activity rate is :5 330,000 uCi/second.
| |
| Reason: Revision removes unnecessary shutdown Page 1 Change Summary Matrix for ODCM Revision 31 Determination A -Administrative Determination B -Main Condenser Offgas Radiation Monitor Determination C -REMP Item Rev 30 Rev 31 Determination Description of Change No. page Paqe Identifier requirement associated with inoperable SJAE radiation monitors based on the implementation of compensatory sampling requirements that adequately determine offgas system release rates ensuring that the limits and requirements of T.S. 3.11.2.6 are not exceeded.
| |
| Provides consistency with industry practice as determined through benchmarking of Exelon and industry BWRs. NUREG-1302 guidance regarding the not putting the system in bypass was not incorporated as this mode is not possible for either Limerick unit. This was confirmed by print reviews and discussion with multiple operators.
| |
| : 5. N/A 93-95, B Added a statement on the methodology for Main 102 Condenser Offgas Radiation Monitor High High Trip, High Trip, and Reset Setpoints.
| |
| Reason: Since the rad monitor was added to the ODCM, it is appropriate to state or reference the basis for the setpoint methodoloqv.
| |
| : 6. 328-333 323-328 c Added all REMP sample location, including locations outside of the minimum requirements of REMP. Included table notations to designate the difference.
| |
| Updated map to reflect all locations.
| |
| Reason: Provide consistency between the ODCM and the Annual Radioloqical Environmental Operatinq Report. 7. 335 330 A Update and additions to references.
| |
| Reason: Reference enhancements.
| |
| Determination A will not go through the rigor of the determination questions.
| |
| Those specific questions are administrative in nature; containing an update to the Table of Contents and Reference section. They are not technical changes. Page 2
