DOCKET NO. 50-302/ LICENSE NO. DPR-72 REQUEST NO.127, REVISION 0 RADIOLOGICAL TECHNICAL SPECIFICATIONS LICENSE DOCUMENT INVOLVED: Technical Specifications PORTIONS:
3.3.3.8 Radioactive Liquid Effluent Monitoring Instrumentation 3.3.3.9 Radioactive Gaseous Ef fluent Monitoring Instrumentation 3.3.3.10 Waste Gas Decay Tank
- Explosive Gas Monitoring Instrumentation 3.7.13.5 Waste Gas Decay Tank
- Explosive Gas Mixture 3.11.1.1 Liquid Effluents
- Concentration 6.9.1.4 Annual and Semi-Annual Reports 6.9.2 Special Reports DESCRIPTION OF REQUEST:
This Change Request corrects errors and clarifles certain radiological effluent technical specifications. Additionally, this submittal requests an allowance to continue to use the Waste Gas Decay Tanks when the hydrogen and oxygen monitors are inoperable if samples are taken periodically.
The specific changes requested are described below.
1)
Change the source check for RM-L7 (T.S. 3.3.3.8) from Daily (D) to Prior (P). Add
" Secondary Drain Tank" to Table 4.11-1 under Batch Waste Release Tanks.
2)
Change the APPLICABLE MODE 5 and MODES IN WHICH SURVEILLANCE REQUIRED for all RM-Al parameters (T.S. 3.3.3.9) from MODES 1,2,3, and 4 and ALL MODES to "During periods of Reactor Building purge."
3)
Delete the footnote on the CHANNEL CHECK for RM-A2, Operating Range Noble Gas Monitor (T.S. 3.3.3.9) and change the SOURCE CHECK from Prior (P) to Not Applicable (NA).
4)
Delete "for up to 14 Days" from the ACTION Statement of Technical Specification 3.3.3.10 and add the following two Action Statements.
b.
If the affected channel (s) cannot be returned to OPERABLE status within 14 days, submit a special report to the Commission pursuant to Specification 6.9.2 within 30 days describing the reasons for inoperability and a schedule for corrective action.
c.
The provisions of 3.0.3 and 3.0.4 are not applicable.
Add an additional special report requirement to Specification 6.9.2 pursuant to Action b above.
5)
Insert the word "in-service" before Waste Gas Decay Tank for surveillance requirement 4.7.13.5.
6)
Delete item n from Specification 6.9.2 requiring a special report for unavailability of vegetable samples. Reference to Specification 3.7.11.4 has been deleted from 6.9.2.
7)
Change individuals to MEMBERS OF THE PUBLIC in Specification 6.9.1.4 (page 6-14b).
okUNO@oNO
REASONS FOR REQUESTS:
1)
When this specification was initially developed, releases through RM-L7 (Secondary Drain Tank liquid effluent line monitor) were being made continuously. These releases are now being made on a " Batch" frequency, therefore, the specifications should be changed to be consistent with other hatch type release monitors.
2)
When the applicable modes for operation of RM-Al (Reactor Building purge exhaust duct monitor) were determined, Crystal River Unit 3 was allowed to purge during all modes. Since then, purging has been restricted to Modes 5 and 6 (Cold Shutdown and Refueling). The operability requirements should reflect this restriction and require monitoring only during time: we can purge.
3)
The inclusion of the footnote "During Periods of Reactor Building Purge" to RM-A2 (Auxiliary Building exhaust monitor) was an obvious typographical error.
The requirement to perform a source check Prior (P) to release through RM-A2 is also an error as this system (Auxiliary Building ) exhaust) is required to operate continuously by another Technical Specification (3.7.8.1.
4)
If the Waste Gas Decay Tanks' hydrogen and/or oxygen monitoring channels are inoperable for more than 14 days, Specification 3.0.3 could be interpreted to require that a shutdown be initiated within one hour. During a plant shutdown, the reactor coolant releases dissolved hydrogen and oxygen due to the lower saturation concentration at the lower pressure. These released gases are generally vented to the Waste Gas Decay Tanks for holdup and radioactive decay. Thus a shutdown can cause an increase in the hydrogen concentrations in the Waste Gas Decay Tanks and is one of the times,when monitoring is especially important. It is inappropriate to require a shutdown when the monitoring channels are inoperable. This Change Request will clarify our position that allows Florida Power to continue power operation when the hydrogen and oxygen monitors on the waste gas decay tanks are inoperable provided grab sampling is continued.
5)
This change will clarify that only the in-service Waste Gas Decay Tank needs to be l
continuously monitored for hydrogen and oxygen concentrations.
l 6)
The unavailability of vegetable samples is reported in the Annual Radiological l
Environmental Operating Report not as a special report as implied here. Specification 3.7.11.4 does not require a special report, thus this reference to 3.7.11.4 has been i
deleted.
7)
MEMBERS OF THE PUBLIC is a defined term, while individuals is not. This change clarifies the scope of individuals to be considered when reporting doses per this requirement. Individuals who are not MEMBERS OF THE PUBLIC are covered under other requirements.
EVALUATION OF REQU31ST:
1)
This change is administrative in nature.
2)
This change is administrative.
3)
This change is administrative.
a
e 4)
This change should improve plant safety. As explained above, a shutdown will cause generation of additional waste gas which is not desirable when the tanks' explosive gas monitoring system is inoperable. Grab sampling will continue to be performed to periodically monitor the tanks' mixtures during monitor inoperability.
5)
This change is editorial.
6)-
This change is administrative.
7)
This change is administrative.

FLORIDA POWER CORPORATION CRYSTAL RIVER UNIT 3 DOCKET NO. 50-302/ LICENSE NO. DPR-72 REQUEST NO.127, REVISION O
. SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION 6
REQUEST FOR:
- Issuance of a Technical Specification amendment to correct errors and clarify certain radiological effluent specifications.
Additionally, we request an amendment to allow continued use of the waste gas decay tanks when the explosive mixture monitoring instrumentation is inoperable if samples are taken periodically.
SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION:
( x ) Amendment involved no significant hazards considerations.
(
) Amendment involves significant hazards considerations.
BASIS FOR DETERMINATION:
This amendment is considered not likely to involve significant hazards considerations, because it is primarily an administrative change to correct errors identified since issuance of the Radiological Effluent Technical Specification, July 1,1954. The portion of the amendment request revising the continued use of the waste gas decay tanks is also a correction. As explained in the attached, the current Specification has no provision for monitor inoperability beyond 14 days.
Generally, this would mean entrance into Specification 3.0.3 is necessary. However, in this case, compliance with 3.0.3 is impossible because.this monitor is required to be operable in all modes. Additionally, commencing a plant shutdown, as implied by 3.0.3, would lead to release of additional hydrogen and, thus could have safety consequences while the monitor is inoperable.
REQUEST IMPLEMENTATION DATE:
Florida Power Corporation requests that this proposed amendment be published in the Federal Register no later than the October amendment noticing date (October 24, 1984).
This publishing date will allow an implementation date during mid-November.
