Gentlemen: | |||
The Baltimore Gas and Electric Company hereby requests an Amendment to its Operating License Nos. DPR-53 & DPR-69 for Calvert Cliffs Unit Nos. 1& 2, respectively, with the submittal of the enclosed proposed changes to the Technical Specifications. | |||
CHANGE NO.1 (FCR 83-85) | |||
Remove existing pages 3/4 1-21 and 3/4 1-22 of the Unit Nos. I and 2 Technical Specifications and replace with attached, marked-up pages 3/4 1-21 and 3/4 1-22, Attachment I to this transmittal. In addition, remove existing pages B3/4 1-4 of the Technical Specification Bases for Unit Nos. I and 2, and replace with attached marked-up pages B3/41-4, Attachment I to this transmittal. | |||
DETERMINATION OF SIGNIFICANT HAZARDS The proposed change to the Technical Specification 3.1.3.3 recognizes the CEA " Full Out" or " Full In" reed switch position indicator as an acceptable means of position indication, so long as the CEA is positioned at the fully withdrawn or fully inserted point, as verified by the applicable position indicator. | |||

- Mr. 3. R. Miller F . September 20,1983 g Page 2 10 CFR 50 General Design Criterion 25 through 27 require redundant reactivity control systems to operate during accidents and transients. One of these reactivity control systems centers around Control Element Assemblies (CEA). Technical Specifications | |||
; 3.1.3.1, 3.1.3.5, and 3.1.3.6 ensure the insertion limits and shutdown margin requirements are met. Technical Specification 3.1.3.3 requires the position indication system of the CEA's be available to ensure reliable means of CEA position determination to ensure the above requirements are met. | |||
The current Technical Specification allows " credit" for the " Full Out" or " Full In" reed switch position indicator, for up to one CEA per group, allowing continued power operation provided that positions of the associated CEA's are periodically verified via the | |||
" Full-Out" or " Full-In" reed ~ switches. The proposed change would allow unrestricted operation with two of the available three position indicators OPERABLE for any CEA. | |||
This change provides essentially the same flexibility, as the current Technical Specification, since Action Statement 3.1.3.3.c already allows continued operation with | |||
; up to .one CEA per group having only the " Full Out" or " Full In" reed switch position | |||
; t indicator and one other indicator. (i.e., voltage divider reed switch or pulse counter) | |||
- OPER ABLE. - By expanding this allowance to any Shutdown or Regulating CEA, no | |||
; additional safety questions have been created which were not previously addressed, since | |||
; actuating the " Full Out" or " Full In" position indicators provide accurate position indication for the associated CEA's. The actual position at which each CEA position | |||
; indicator " Full Out" or " Full In" reed switch actuates is delineated in Updated FSAR Section 7.5.3.4 and Figure 7-12. FSAR Figure 7-12 shows the Upper Electrical Limit | |||
' actuates at approximately 136", and the Lower Electrical Limit actuates at approximately 1".. | |||
The proposed surveillance requirements require verification of actual CEA position once i per 12 hours, utilizing the required CEA position indication channels, and once every four hours when the Deviation circuit is inoperable. These surveillance requirements should adequately. insure the required CEA position indicators remain OPERABLE. The i requirements of CEA insertion limits as specified in Technical Specification 3.1.3.6 L would still assure that the insertion limits are met,'and Technical Specification 3.1.3.5 would ensure the Shutdown Margin requirements are met. | |||
I Updated.FSAR Section 14.2, Control Element Assembly Withdrawal Event, assumes the operability of the CMI(CEA Motion innibit) function. The CMI function is required to be | |||
' OPERABLE 'by . Tecnnical Specification 3.1.3.1., so the operability and ACTION requirements for this function are already addressed by that Technical Specification. | |||
The ACTION requirements have been revised to address the " Full Out" or " Full In" reed L ' switch position indicator as an allowable indicator for continued operation. The current L ACTION requirements allow continued operation for 24 hours with more than one CEA pulse counting channel inoperable, and the proposed ACTION requirement simply allows either the voltage divider or the " Full Out" or " Full in" reed switch position indicator to service as ' position indication, with the same time interval allowed for continued operation. | |||

This proposed change does not increase the probability of occurrence or consequences of an accident previously evaluated on the FSAR, since the change still ensures that CEA position indication is available to ensure the assumptions of the Updated FSAR are maintained, as described above. No new or different kind of accident from any accident previously evaluted in the FSAR is created, because the change only provides full acknowledgement of the operability of an independent meeas of CEA position indication, as described above. No reduction in the margin of safety as decribed in the bases for Technical Specification 3/4.1.3 would result from the proposed change. This is because | |||
. the Technical Specification Bases already describe the " Full Out" or " Full In" limits as providing an additional independent means for determining the CEA positions when the CEAs are at either their fully inserted or fully withdrawn positions. Adding the words | |||
" OPERABILITY and" to the ' ACTION statements applicable to inoperable CEA position indicators" represents an administrative clarification to make the Bases consistent with the proposed change. | |||
; ~ Based upon the above determinations, and the guidance provided in page 14870 of Federal Register Notice dated April 6,'1983, Examples of Amendments that Are Considered Not Likely to Involve Significant Hazards Considerations, subsection (i), this proposed change has been determined to not involve a significant hazard. | |||

Remove pages 3/4 '6-10 and 3/4 6-12 of the Unit 1 and 2 Technical Specifications and replace with marked-up pages 3/4 6-10 and 3/4 6-12, Attachment (2) of this transmittal. | |||
DETERMINATION OF SIGNIFICANT HAZARDS The containment air recirculation and cooling units are desuibed in Section 6.5 of the l - Updated Final Safety Analysis Report. Paragraph 6.5.1 of the Updated FSAR, Design Basis, states in part: | |||
7 "The function of the containment air recirculation and cooling system is i to remove heat from the containment atmosphere during normal plant operation. In the event of occurrence of a LOCI, the system functions 'o limit the containment pressure rise to a level below the design value..." | |||
i and "The containment air recirculation and cooling system is independent ' | |||
of the safety injection and containment spray systems. It is sized such - | |||
that, following a' LOCI, three of the four containment air coolers will limit the containment pressure to less than the containment design | |||
! pressure even if the containment spray system does not operate". | |||
!~ The containment spray system is described in Section 6.4 of the Updated FSAR. | |||
Paragraph 6.4.1 of the Update FSAR, Design Basis, states in part: | |||

Mr. 3. R. Miller September 20,1983 Page 4 "The function of the containment spray system is to limit the containment atmosphere pressure and temperature following a LOCl and thus reduce the possibility of leakage of airborne radioactivity to the outside environment". | |||
Paragraph 6.4.2 of the Updated FSAR states in part: | |||
! "The capacity of the two containment spray pumps is such that they can i limit the containment pressure to less than its design value following a LOCI without giving credit to the containment coolers". | |||
. Both redundant systems are designed to meet the requirements of 10 CFR 50 General Design Criterion 38, Containment Heat Removal. This General Design Criterion (GDC) requires that "The system safety function shall be to reduce rapidly, consistent with the | |||
- functioning of other associated systems, the containment pressure and temperature following any loss-of-coolant accident and maintain them at acceptably low levels". The GDC also requires that anticipated single failures be assumed. | |||
i The current Technical Specifications do not address the redundancy of the containment air recirculation and cooling units and the containment spray systems. With the proposed ACTION requirements, the minimum equipment required to limit the containment pressure and temperature rise following a LOCl will always be available. The containment air recirculation and cooling units are each 331/3% of the required cooling capacity. This is because three units meet the 100% cooling requirement. The | |||
[ containment spray trains are each 50% of the required cooling capacity. This is because L two units meet the 100% cooling requirement. Therefore, the following combinations would meet or exceed the required cooling capacity: | |||
; a) . I containment spray train plus two containment coolers (116.7 %) | |||
b) - 2 containment spray trains only (100%) | |||
[ | |||
c) 3 containment cooling units only (100%) | |||
L-L The above is consistent with Section 6.4.3 of the Updated FSAR, page 6-29. | |||
: By rewording the ACTION statements to be consistent with the CE-STS provided in NUREG-0212, the redundancy _of the containment spray trains and containment air recirc'ilation and cooling units can be addressed in the Technical Specifications. The OPERABILITY and ACTION requirements from the C-E STS have been modified slightly l to establish the requirement for operability of the containment coolers during Modes 1, l 2, and 3, which is consistent with the current Technical Specification applicability and the accident analysis assumptions in Chapter 14 of the Updated FSAR. | |||
[ The containment spray system is required by Chapter 14.24 of the Updated FSAR for | |||
' iodine removal from the containment atmosphere, so the OPERABILITY and ACTION requirements for the containment spray system cannot be changed to substitute the containment coolers for an inoperable containment spray train. | |||

Mr. 3. R. Miller | |||
. . September 20,1983 Page 5 1 | |||
The proposed change does not increase the probability of occurrence of an accident previously evaluated in the Updated FSAR. This is because the minimum OPERABILITY requirements still allow for single failure of either containment spray or containment air | |||
; recirculation and cooling systems, as described in Chapter 6, Tables 6-7 and 6-9 of the | |||
. Updated FSAR. | |||
The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated in the Updated FSAR. This is because the requirements of General Design Criterion 38 are still being satisfied with the new | |||
. ACTION requirements. In addition, no additional components are being added or deleted by this change. | |||
The proposed change does not reduce the margin of safety as described in the ba'ses for Technical Specification 3/4 6.2.2. Section 3/4 6.2.2 of the Technical Specification bases states the following: | |||
[ "The OPERABILITY of the containment cooling system ensures that 1) the contain_ ment air temperature will be maintained within limits during normal operation and 2) adequate heat removal capacity is available when operated in conjunction with the containment spray systems during post- | |||
, LOCA conditions". | |||
In the. new proposed ACTION requirements, the containment spray system will be i- credited to meet the minimum containment cooling requirements following a LOCI, in conjunction with the containment air recirculation and cooling units, as described above. | |||
t Based upon the above determinations, we have concluded that the proposed change | |||
; represents an example of an amendment - that is considered not likely to involve significant hazards considerations under Section (i), as described in Page 14870 of Federal Register Notice dated April 6,1983. | |||
l ' CHANGE NO. 3 (BG&E FCR 83-13) | |||
Add snubber 2-15-10 to Table 3.7-4 as shown on attached marked-up page 3/4 7-31 of | |||
; Unit 2 Technical Specifications, Attachment 3 to this transmittal. | |||
t DETERMINATION OF SIGNIFICANT HAZARDS This request constitutes part of the corrective action delineated in Licensee Event Report 50-318/83-09. | |||
Snubber 2-15-10 is installed on Class 11 safety-related piping in the Component Cooling System and meets the criteria for inclusion in the Technical Specifications. The snubber has been ' visually inspected and verified to be fully operational through functional l testing, thus, it has been fully upgraded to safety-related standards. Due to an oversight, this snubber had been unintentionally omitted from the safety-related snubber program for Unit 2. This snubber represents a component in the Component Cooling System, | |||

Mr. 3. R. Miller September 20,1983 Page 6 which is described in the Updated Final Safety Analysis Report, Section 9.5. The addition of the snuboer to the safety-related surveillance program represents an improvement to our existing surveillance program. | |||
Accordingly, inclusion of the snubber 2-15-10 into the Unit 2 Technical Specifications will provide substantial assurance the snubber will be able to perform its design function in supporting dynamic loads on the Class 11 safety-related piping system. | |||
The Component Cooling Water System is described in Table 9-17A of the Updated FSAR as providing cooling water for safety injection pumps and containment spray water (via the shutdown cooling heat exchanger). No previously analyzed accident is affected by this proposed change, since the Updated FSAR considers a total loss of the component cooling system due to passive failure. | |||
l l No new accidents not previously analyzed in the Updated FSAR are created, since the | |||
! proposed change is administrative in nature. The margin of safety as defined in the bases i for Technical Specification 3.7.8 is not reduced since the snubber has been verified to be i operable by both visual inspection and functional testing, and has been included in the l surveillance program for snubbers in safety-related systems. | |||
Based upon the above considerations, the requested change is administrative in nature and does not involve a significant hazard. | |||
i CHANGE NO. 4 (BG&E FCR 83-1036) | |||
Remove existing pages . 3/4 7-28, 3/4 7-53, and 3/4 7-59 of the Unit 1 Technical Specifications and replace with the attached marked-up pages, Attachment 4 to this j transmittal. | |||
DETERMINATON OF SIGNIFICANT HAZARDS Recent concerns within BG&E and NRC have precipitated a review of the original l | |||
construction list by the Architectural Engineer to establish a controlled document that lists all safety-related and seismic hydraulic snubbers in the Calvert Cliffs Nuclear Power Plant. During this review, an error was discovered in the main steam hydraulic s | |||
! snubber listing for Unit 1. Apparently this error was initiated by a BG&E Request for Amendment Letter dated June 17, 1982. License Amendments 77 and 58 added some i main steam line seismic hydraulic snubbers to the Table 3.7-4 in the Technical Specifications. Two snubbers added in that letter were incorrectly designated as snubber 1-83-17 and 1-83-24. These snubbers should actually have been designated as snubber l 1-83-13 and 1-83-18. During the period when the Technical Specifications listed the wrong snubber designations, the correct snubbers had been survelled. Therefore, these snubbers remained operable throughout the period. | |||

c Mr. 3. R. Miller | |||
- September 20,1983 Page 7 A system - walkdown performed by BG&E and the NRC Senior Resident inspector | |||
~ | |||
identified some administrative corrections for Table 3.7-4. These changes address | |||
~ | |||
changing the "snuober location" column for one snubber (1-11-13) and the "especially | |||
; difficult to remove" column for two snubbers (1-11-13 and 1-11-11A). These changes only provide administrative clarification of the snubber table, and likewise do not affect the snubber operability or surveillance requirements. No accidents previously analyzed in the Updated FSAR are affected by either of these changes, since they only provide administrative clarification. No new accidents not previously analyzed would be created, | |||
- since no new systems or components are being added by these changes. The margin of safety as defined in the bases for Technical Specification 3.7.8 are not affected, since the changes do not affect the operability or surveillance requirements for the snubbers. | |||
~ Based upon the above considerations, the requested changes are administrative in nature and do not constitute a significant hazard. | |||
- CHANGE NO. 5 (BG&E FCR 83-1066) | |||
Remove. existing page 3/4 7-46 of the Unit 1 Technical Specifications and insert the attached,' marked-up page 3/4 7-46, Attachment (5) to this transmittal. | |||
DETERMINATION OF SIGNIFICANT HAZARDS The proposed change deletes snubber 1-60-7 from the list of snubbers in Table 3.7-4 of the Unit 1 Technical Specifications. Under an earlier modification, the Architectural Engineer performed revised stress calculations on safety-related systems to upgrade supports and hangers in accordance with IE Bulletin 79-14. As a result of these revised j | |||
calculations, it was determined that this snubber was no longer required, due to low movement of the service water line under po.tulated loading conditions, including - | |||
normal, transient, and analyzed accident conditions. | |||
This snubber is located on the service water return line from #13 Containment Air Recirculation and Cooling Unit, in Unit 1 Containment on the 64 foot elevation. The service Lwater spstem is described in the Updated FSAR in Table 9-17A as providing cooling for the' Containment Coolers and Diesel Generators. No previously enalyzed accident is affected by this proposed change, since the Updated FSAP considers loss of a service water subsystem in the passive failure analysis. Since the stress calculations l have shown the snubber is no ; longer required, additional assurance is provided that no | |||
!: new accidents not previously analyzed in the Updated FSAR are created. | |||
The margin of safety in the bases for Technicc! Specification 3.7.8 is not reduced since this snubber is no longer required, and the remaining snubbers in the Table 3.7-4 are not affected, and no changes are being proposed to the OPER ABILITY and SURVEILLANCE requirements for the remaining snubbers in the Table. | |||
~ Bas'ed upon the above considerations, the requested change is administrative in mture and does not involve a significant hazard. | |||

DETERMINATION OF SIGNIFICANT HAZARDS CONSIDER ATIONS Reference (c) requires installation of a main feedwater train trip to satisfy the 1 requirements of IE Bulletin 80-04, by November 17, 1983, for Calvert Cliffs Units 1 and i | |||
: 2. This trip will be actuated by a Containment Spray Actuation Signal (CSAS), I Subchannels A-3 and B-3, and/or Steam Generator Isolation Signal (SGIS), subchannels A-1 and B-1, and will trip the following components: main feedwater pumps, condensate booster pumps, and heater drain pumps for the affected unit (s). In addition the actuation signals will close the Main Steam Isolation Yalves (MSIV's) and Main Feedwater Isolation Valves (MFIV's) for the affected Unit (s). The only other components currently actuated by the CSAS Subchannel, supply and return service water valves for the spent fuel pool coolers, will no longer be actuated from CSAS Subchannels A-3 and B-3. These valves will be actuated by another CSAS Subchannel. The surveillance requirements for these valves will be controlled under the requirements of the other CSAS Subchannel. We understand based on' phone conversations between our staff and Mr. Jaffe that we will receive written confirmation allowing us to delay installation of the Unit 2 IE Bulletin | |||
~ 80-04 fix until the Unit 2 refueling outage beginning in Spring of 1984. | |||
This proposed change would exempt CSAS logic Subchannels A-3 and B-3 from testing ouring operation but would require testing at least once par 18 months during shutdown. | |||
: i. This change is necessary because testing of CSAS logic Subchannels A-3 and B-3 wnile at power will trip the associated unit due to loss of main feedwater and main steam isolation -valve closure. Recent phone conversations between BG&E personnel and the NRC Project Manager have determined that Technical Specification coverage of the Main Feedwater and MSIV trip on high containment pressure is not required. Adding these surveillance requirements imposes an additional limitation, restriction and control not presently included in the Technical Specifications. According to NRC Generic Letter i | |||
83-19, this proposed change is an example of an amendment which is not likely to involve a significant hazards consideration, as described under section (ii), page 14870 of the Federal Register Notice dated April 6,1983. | |||
l- This proposed change will not result in any significant increase in the probability or consequences of any accident analyzed in the Updated FSAR. No new previously l | |||
unanalyzed accident will be created by the proposed change, since the addition of the additional trip function to ESFAS will result in an improvement to safety. The proposed change to the Technical Specifications will not result in any reduction in the margin of l | |||
safety as described in the bases for Technical Specifications Bases 3/4 3.3. Based upon | |||
: 'the above considerations this change has been determined to involve no significant l- hazards per 10 CFR 50.92. | |||

. '. ATTAClutENT I i; REACTIVITY CONTROL SYSTEr5 BASES Overpower margin is provided to protect the core in the event of a large misalignment (> 15 inches) of a CEA. However, this misalignment would cause distortion of the core power distribution. The reactor protective system would not detect the degradation-in radial peaking factors and since varia-tions in other system parameters (e.g., pressure and coolant temperature) may | |||
'not be sufficient to cause trips, it is probable that the reactor could be operating with-process variables less conservative than those assumed .in -- | |||
generating LC0 and LSSS setpoints. Therefore, the ACTION statement associated with the large misalignment of a CEA requires a prompt and significt.nt recuc-tion in THERMAL P0'JER prior to attempting realignment of the misaligned CEA. | |||
t, | |||
! The ACTION statements applicable to misaligned or inoperable CEAs include l requirements to align the OPERABLE CEAs in a given group with ti.e ino::erable Conformance with these alignment requirements bring the core, within a i CEA. | |||
e' short period of time, to a configuration consistent with that assumed in ll generating LCO and LSSS setpoints. However, extended operation with CEAs | |||
- is significantly inserted in the core may lead to perturbations in 1) Iccal burnup, 2) peaking factors, and 3) available shutdown margin whicn are more ll adverse i than the conditions assumed to exist in the safety analyses and LCO | |||
. and.LSSS setpoints determination Therefore, time limits have been im;:osed | |||
! on operation with inoperable CEAs to preclude such adverse conditions from developing. g Operability of the CEA position indicators is required to determine CEA positions and thereby ensure compliance with the CEA alignment and insertion limits and ensures proper operation of the rod block circuit. The CEA " Full In" and " Full Out" limits provide an additional independent means for dete mining the CEA positions when the CEAs are.at either their fully inserted or , | |||
i fully withdrawn positions. Therefore, thefACTICU stataments applicable ;o l l inoperable CEA position indicators permit continued operations when the positions of CEAs with inoperable position indicators can be verified by the | |||
" Full In" or " Full Cut" limits. | |||
CEA positions and OPERABILITY of the CEA position indicators are reqaired to be verified on a nominal basis of once per 12 hours with more frequent verifications required if an automatic monitoring channel is inoperable. | |||
These verification frequencies are adequate for assuring that the applicabic LCOs are satisfied. | |||

Gentlemen:
The Baltimore Gas and Electric Company hereby requests an Amendment to its Operating License Nos. DPR-53 & DPR-69 for Calvert Cliffs Unit Nos. 1& 2, respectively, with the submittal of the enclosed proposed changes to the Technical Specifications.
CHANGE NO.1 (FCR 83-85)
Remove existing pages 3/4 1-21 and 3/4 1-22 of the Unit Nos. I and 2 Technical Specifications and replace with attached, marked-up pages 3/4 1-21 and 3/4 1-22, Attachment I to this transmittal. In addition, remove existing pages B3/4 1-4 of the Technical Specification Bases for Unit Nos. I and 2, and replace with attached marked-up pages B3/41-4, Attachment I to this transmittal.
DETERMINATION OF SIGNIFICANT HAZARDS The proposed change to the Technical Specification 3.1.3.3 recognizes the CEA " Full Out" or " Full In" reed switch position indicator as an acceptable means of position indication, so long as the CEA is positioned at the fully withdrawn or fully inserted point, as verified by the applicable position indicator.

- Mr. 3. R. Miller F . September 20,1983 g Page 2 10 CFR 50 General Design Criterion 25 through 27 require redundant reactivity control systems to operate during accidents and transients. One of these reactivity control systems centers around Control Element Assemblies (CEA). Technical Specifications
- 3.1.3.1, 3.1.3.5, and 3.1.3.6 ensure the insertion limits and shutdown margin requirements are met. Technical Specification 3.1.3.3 requires the position indication system of the CEA's be available to ensure reliable means of CEA position determination to ensure the above requirements are met.
The current Technical Specification allows " credit" for the " Full Out" or " Full In" reed switch position indicator, for up to one CEA per group, allowing continued power operation provided that positions of the associated CEA's are periodically verified via the
" Full-Out" or " Full-In" reed ~ switches. The proposed change would allow unrestricted operation with two of the available three position indicators OPERABLE for any CEA.
This change provides essentially the same flexibility, as the current Technical Specification, since Action Statement 3.1.3.3.c already allows continued operation with
- up to .one CEA per group having only the " Full Out" or " Full In" reed switch position
- t indicator and one other indicator. (i.e., voltage divider reed switch or pulse counter)
- OPER ABLE. - By expanding this allowance to any Shutdown or Regulating CEA, no
- additional safety questions have been created which were not previously addressed, since
- actuating the " Full Out" or " Full In" position indicators provide accurate position indication for the associated CEA's. The actual position at which each CEA position
- indicator " Full Out" or " Full In" reed switch actuates is delineated in Updated FSAR Section 7.5.3.4 and Figure 7-12. FSAR Figure 7-12 shows the Upper Electrical Limit
' actuates at approximately 136", and the Lower Electrical Limit actuates at approximately 1"..
The proposed surveillance requirements require verification of actual CEA position once i per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, utilizing the required CEA position indication channels, and once every four hours when the Deviation circuit is inoperable. These surveillance requirements should adequately. insure the required CEA position indicators remain OPERABLE. The i requirements of CEA insertion limits as specified in Technical Specification 3.1.3.6 L would still assure that the insertion limits are met,'and Technical Specification 3.1.3.5 would ensure the Shutdown Margin requirements are met.
I Updated.FSAR Section 14.2, Control Element Assembly Withdrawal Event, assumes the operability of the CMI(CEA Motion innibit) function. The CMI function is required to be
' OPERABLE 'by . Tecnnical Specification 3.1.3.1., so the operability and ACTION requirements for this function are already addressed by that Technical Specification.
The ACTION requirements have been revised to address the " Full Out" or " Full In" reed L ' switch position indicator as an allowable indicator for continued operation. The current L ACTION requirements allow continued operation for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with more than one CEA pulse counting channel inoperable, and the proposed ACTION requirement simply allows either the voltage divider or the " Full Out" or " Full in" reed switch position indicator to service as ' position indication, with the same time interval allowed for continued operation.

This proposed change does not increase the probability of occurrence or consequences of an accident previously evaluated on the FSAR, since the change still ensures that CEA position indication is available to ensure the assumptions of the Updated FSAR are maintained, as described above. No new or different kind of accident from any accident previously evaluted in the FSAR is created, because the change only provides full acknowledgement of the operability of an independent meeas of CEA position indication, as described above. No reduction in the margin of safety as decribed in the bases for Technical Specification 3/4.1.3 would result from the proposed change. This is because
. the Technical Specification Bases already describe the " Full Out" or " Full In" limits as providing an additional independent means for determining the CEA positions when the CEAs are at either their fully inserted or fully withdrawn positions. Adding the words
" OPERABILITY and" to the ' ACTION statements applicable to inoperable CEA position indicators" represents an administrative clarification to make the Bases consistent with the proposed change.
- ~ Based upon the above determinations, and the guidance provided in page 14870 of Federal Register Notice dated April 6,'1983, Examples of Amendments that Are Considered Not Likely to Involve Significant Hazards Considerations, subsection (i), this proposed change has been determined to not involve a significant hazard.
' CHANGE NO. 2 (BG&E FCR 83-86)
~
Remove pages 3/4 '6-10 and 3/4 6-12 of the Unit 1 and 2 Technical Specifications and replace with marked-up pages 3/4 6-10 and 3/4 6-12, Attachment (2) of this transmittal.
DETERMINATION OF SIGNIFICANT HAZARDS The containment air recirculation and cooling units are desuibed in Section 6.5 of the l - Updated Final Safety Analysis Report. Paragraph 6.5.1 of the Updated FSAR, Design Basis, states in part:
7 "The function of the containment air recirculation and cooling system is i to remove heat from the containment atmosphere during normal plant operation. In the event of occurrence of a LOCI, the system functions 'o limit the containment pressure rise to a level below the design value..."
i and "The containment air recirculation and cooling system is independent '
of the safety injection and containment spray systems. It is sized such -
that, following a' LOCI, three of the four containment air coolers will limit the containment pressure to less than the containment design
! pressure even if the containment spray system does not operate".
!~ The containment spray system is described in Section 6.4 of the Updated FSAR.
Paragraph 6.4.1 of the Update FSAR, Design Basis, states in part:

Mr. 3. R. Miller September 20,1983 Page 4 "The function of the containment spray system is to limit the containment atmosphere pressure and temperature following a LOCl and thus reduce the possibility of leakage of airborne radioactivity to the outside environment".
Paragraph 6.4.2 of the Updated FSAR states in part:
! "The capacity of the two containment spray pumps is such that they can i limit the containment pressure to less than its design value following a LOCI without giving credit to the containment coolers".
. Both redundant systems are designed to meet the requirements of 10 CFR 50 General Design Criterion 38, Containment Heat Removal. This General Design Criterion (GDC) requires that "The system safety function shall be to reduce rapidly, consistent with the
- functioning of other associated systems, the containment pressure and temperature following any loss-of-coolant accident and maintain them at acceptably low levels". The GDC also requires that anticipated single failures be assumed.
i The current Technical Specifications do not address the redundancy of the containment air recirculation and cooling units and the containment spray systems. With the proposed ACTION requirements, the minimum equipment required to limit the containment pressure and temperature rise following a LOCl will always be available. The containment air recirculation and cooling units are each 331/3% of the required cooling capacity. This is because three units meet the 100% cooling requirement. The
[ containment spray trains are each 50% of the required cooling capacity. This is because L two units meet the 100% cooling requirement. Therefore, the following combinations would meet or exceed the required cooling capacity:
- a) . I containment spray train plus two containment coolers (116.7 %)
b) - 2 containment spray trains only (100%)
[
c) 3 containment cooling units only (100%)
L-L The above is consistent with Section 6.4.3 of the Updated FSAR, page 6-29.
- By rewording the ACTION statements to be consistent with the CE-STS provided in NUREG-0212, the redundancy _of the containment spray trains and containment air recirc'ilation and cooling units can be addressed in the Technical Specifications. The OPERABILITY and ACTION requirements from the C-E STS have been modified slightly l to establish the requirement for operability of the containment coolers during Modes 1, l 2, and 3, which is consistent with the current Technical Specification applicability and the accident analysis assumptions in Chapter 14 of the Updated FSAR.
[ The containment spray system is required by Chapter 14.24 of the Updated FSAR for
' iodine removal from the containment atmosphere, so the OPERABILITY and ACTION requirements for the containment spray system cannot be changed to substitute the containment coolers for an inoperable containment spray train.

Mr. 3. R. Miller
. . September 20,1983 Page 5 1
The proposed change does not increase the probability of occurrence of an accident previously evaluated in the Updated FSAR. This is because the minimum OPERABILITY requirements still allow for single failure of either containment spray or containment air
- recirculation and cooling systems, as described in Chapter 6, Tables 6-7 and 6-9 of the
. Updated FSAR.
The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated in the Updated FSAR. This is because the requirements of General Design Criterion 38 are still being satisfied with the new
. ACTION requirements. In addition, no additional components are being added or deleted by this change.
The proposed change does not reduce the margin of safety as described in the ba'ses for Technical Specification 3/4 6.2.2. Section 3/4 6.2.2 of the Technical Specification bases states the following:
[ "The OPERABILITY of the containment cooling system ensures that 1) the contain_ ment air temperature will be maintained within limits during normal operation and 2) adequate heat removal capacity is available when operated in conjunction with the containment spray systems during post-
, LOCA conditions".
In the. new proposed ACTION requirements, the containment spray system will be i- credited to meet the minimum containment cooling requirements following a LOCI, in conjunction with the containment air recirculation and cooling units, as described above.
t Based upon the above determinations, we have concluded that the proposed change
- represents an example of an amendment - that is considered not likely to involve significant hazards considerations under Section (i), as described in Page 14870 of Federal Register Notice dated April 6,1983.
l ' CHANGE NO. 3 (BG&E FCR 83-13)
Add snubber 2-15-10 to Table 3.7-4 as shown on attached marked-up page 3/4 7-31 of
- Unit 2 Technical Specifications, Attachment 3 to this transmittal.
t DETERMINATION OF SIGNIFICANT HAZARDS This request constitutes part of the corrective action delineated in Licensee Event Report 50-318/83-09.
Snubber 2-15-10 is installed on Class 11 safety-related piping in the Component Cooling System and meets the criteria for inclusion in the Technical Specifications. The snubber has been ' visually inspected and verified to be fully operational through functional l testing, thus, it has been fully upgraded to safety-related standards. Due to an oversight, this snubber had been unintentionally omitted from the safety-related snubber program for Unit 2. This snubber represents a component in the Component Cooling System,

Mr. 3. R. Miller September 20,1983 Page 6 which is described in the Updated Final Safety Analysis Report, Section 9.5. The addition of the snuboer to the safety-related surveillance program represents an improvement to our existing surveillance program.
Accordingly, inclusion of the snubber 2-15-10 into the Unit 2 Technical Specifications will provide substantial assurance the snubber will be able to perform its design function in supporting dynamic loads on the Class 11 safety-related piping system.
The Component Cooling Water System is described in Table 9-17A of the Updated FSAR as providing cooling water for safety injection pumps and containment spray water (via the shutdown cooling heat exchanger). No previously analyzed accident is affected by this proposed change, since the Updated FSAR considers a total loss of the component cooling system due to passive failure.
l l No new accidents not previously analyzed in the Updated FSAR are created, since the
! proposed change is administrative in nature. The margin of safety as defined in the bases i for Technical Specification 3.7.8 is not reduced since the snubber has been verified to be i operable by both visual inspection and functional testing, and has been included in the l surveillance program for snubbers in safety-related systems.
Based upon the above considerations, the requested change is administrative in nature and does not involve a significant hazard.
i CHANGE NO. 4 (BG&E FCR 83-1036)
Remove existing pages . 3/4 7-28, 3/4 7-53, and 3/4 7-59 of the Unit 1 Technical Specifications and replace with the attached marked-up pages, Attachment 4 to this j transmittal.
DETERMINATON OF SIGNIFICANT HAZARDS Recent concerns within BG&E and NRC have precipitated a review of the original l
construction list by the Architectural Engineer to establish a controlled document that lists all safety-related and seismic hydraulic snubbers in the Calvert Cliffs Nuclear Power Plant. During this review, an error was discovered in the main steam hydraulic s
! snubber listing for Unit 1. Apparently this error was initiated by a BG&E Request for Amendment Letter dated June 17, 1982. License Amendments 77 and 58 added some i main steam line seismic hydraulic snubbers to the Table 3.7-4 in the Technical Specifications. Two snubbers added in that letter were incorrectly designated as snubber 1-83-17 and 1-83-24. These snubbers should actually have been designated as snubber l 1-83-13 and 1-83-18. During the period when the Technical Specifications listed the wrong snubber designations, the correct snubbers had been survelled. Therefore, these snubbers remained operable throughout the period.

c Mr. 3. R. Miller
- September 20,1983 Page 7 A system - walkdown performed by BG&E and the NRC Senior Resident inspector
~
identified some administrative corrections for Table 3.7-4. These changes address
~
changing the "snuober location" column for one snubber (1-11-13) and the "especially
- difficult to remove" column for two snubbers (1-11-13 and 1-11-11A). These changes only provide administrative clarification of the snubber table, and likewise do not affect the snubber operability or surveillance requirements. No accidents previously analyzed in the Updated FSAR are affected by either of these changes, since they only provide administrative clarification. No new accidents not previously analyzed would be created,
- since no new systems or components are being added by these changes. The margin of safety as defined in the bases for Technical Specification 3.7.8 are not affected, since the changes do not affect the operability or surveillance requirements for the snubbers.
~ Based upon the above considerations, the requested changes are administrative in nature and do not constitute a significant hazard.
- CHANGE NO. 5 (BG&E FCR 83-1066)
Remove. existing page 3/4 7-46 of the Unit 1 Technical Specifications and insert the attached,' marked-up page 3/4 7-46, Attachment (5) to this transmittal.
DETERMINATION OF SIGNIFICANT HAZARDS The proposed change deletes snubber 1-60-7 from the list of snubbers in Table 3.7-4 of the Unit 1 Technical Specifications. Under an earlier modification, the Architectural Engineer performed revised stress calculations on safety-related systems to upgrade supports and hangers in accordance with IE Bulletin 79-14. As a result of these revised j
calculations, it was determined that this snubber was no longer required, due to low movement of the service water line under po.tulated loading conditions, including -
normal, transient, and analyzed accident conditions.
This snubber is located on the service water return line from #13 Containment Air Recirculation and Cooling Unit, in Unit 1 Containment on the 64 foot elevation. The service Lwater spstem is described in the Updated FSAR in Table 9-17A as providing cooling for the' Containment Coolers and Diesel Generators. No previously enalyzed accident is affected by this proposed change, since the Updated FSAP considers loss of a service water subsystem in the passive failure analysis. Since the stress calculations l have shown the snubber is no ; longer required, additional assurance is provided that no
!: new accidents not previously analyzed in the Updated FSAR are created.
The margin of safety in the bases for Technicc! Specification 3.7.8 is not reduced since this snubber is no longer required, and the remaining snubbers in the Table 3.7-4 are not affected, and no changes are being proposed to the OPER ABILITY and SURVEILLANCE requirements for the remaining snubbers in the Table.
~ Bas'ed upon the above considerations, the requested change is administrative in mture and does not involve a significant hazard.

Mr. 3; R. Miller September 20,1983 Page 8 CHANGE NO. 6 (8G&E FCR 83-1039)
Remove existing pages 3/4 3-22 and 3/4 3-24 of the Unit 1 Technical Specifications and replace with attached, marked-up pages 3/4 3-22 and 3/4 3-24, Attachment (6) of this I transmittal. j l
DETERMINATION OF SIGNIFICANT HAZARDS CONSIDER ATIONS Reference (c) requires installation of a main feedwater train trip to satisfy the 1 requirements of IE Bulletin 80-04, by November 17, 1983, for Calvert Cliffs Units 1 and i
- 2. This trip will be actuated by a Containment Spray Actuation Signal (CSAS), I Subchannels A-3 and B-3, and/or Steam Generator Isolation Signal (SGIS), subchannels A-1 and B-1, and will trip the following components: main feedwater pumps, condensate booster pumps, and heater drain pumps for the affected unit (s). In addition the actuation signals will close the Main Steam Isolation Yalves (MSIV's) and Main Feedwater Isolation Valves (MFIV's) for the affected Unit (s). The only other components currently actuated by the CSAS Subchannel, supply and return service water valves for the spent fuel pool coolers, will no longer be actuated from CSAS Subchannels A-3 and B-3. These valves will be actuated by another CSAS Subchannel. The surveillance requirements for these valves will be controlled under the requirements of the other CSAS Subchannel. We understand based on' phone conversations between our staff and Mr. Jaffe that we will receive written confirmation allowing us to delay installation of the Unit 2 IE Bulletin
~ 80-04 fix until the Unit 2 refueling outage beginning in Spring of 1984.
This proposed change would exempt CSAS logic Subchannels A-3 and B-3 from testing ouring operation but would require testing at least once par 18 months during shutdown.
- i. This change is necessary because testing of CSAS logic Subchannels A-3 and B-3 wnile at power will trip the associated unit due to loss of main feedwater and main steam isolation -valve closure. Recent phone conversations between BG&E personnel and the NRC Project Manager have determined that Technical Specification coverage of the Main Feedwater and MSIV trip on high containment pressure is not required. Adding these surveillance requirements imposes an additional limitation, restriction and control not presently included in the Technical Specifications. According to NRC Generic Letter i
83-19, this proposed change is an example of an amendment which is not likely to involve a significant hazards consideration, as described under section (ii), page 14870 of the Federal Register Notice dated April 6,1983.
l- This proposed change will not result in any significant increase in the probability or consequences of any accident analyzed in the Updated FSAR. No new previously l
unanalyzed accident will be created by the proposed change, since the addition of the additional trip function to ESFAS will result in an improvement to safety. The proposed change to the Technical Specifications will not result in any reduction in the margin of l
safety as described in the bases for Technical Specifications Bases 3/4 3.3. Based upon
- 'the above considerations this change has been determined to involve no significant l- hazards per 10 CFR 50.92.

. '. ATTAClutENT I i; REACTIVITY CONTROL SYSTEr5 BASES Overpower margin is provided to protect the core in the event of a large misalignment (> 15 inches) of a CEA. However, this misalignment would cause distortion of the core power distribution. The reactor protective system would not detect the degradation-in radial peaking factors and since varia-tions in other system parameters (e.g., pressure and coolant temperature) may
'not be sufficient to cause trips, it is probable that the reactor could be operating with-process variables less conservative than those assumed .in --
generating LC0 and LSSS setpoints. Therefore, the ACTION statement associated with the large misalignment of a CEA requires a prompt and significt.nt recuc-tion in THERMAL P0'JER prior to attempting realignment of the misaligned CEA.
t,
! The ACTION statements applicable to misaligned or inoperable CEAs include l requirements to align the OPERABLE CEAs in a given group with ti.e ino::erable Conformance with these alignment requirements bring the core, within a i CEA.
e' short period of time, to a configuration consistent with that assumed in ll generating LCO and LSSS setpoints. However, extended operation with CEAs
- is significantly inserted in the core may lead to perturbations in 1) Iccal burnup, 2) peaking factors, and 3) available shutdown margin whicn are more ll adverse i than the conditions assumed to exist in the safety analyses and LCO
. and.LSSS setpoints determination Therefore, time limits have been im;:osed
! on operation with inoperable CEAs to preclude such adverse conditions from developing. g Operability of the CEA position indicators is required to determine CEA positions and thereby ensure compliance with the CEA alignment and insertion limits and ensures proper operation of the rod block circuit. The CEA " Full In" and " Full Out" limits provide an additional independent means for dete mining the CEA positions when the CEAs are.at either their fully inserted or ,
i fully withdrawn positions. Therefore, thefACTICU stataments applicable ;o l l inoperable CEA position indicators permit continued operations when the positions of CEAs with inoperable position indicators can be verified by the
" Full In" or " Full Cut" limits.
CEA positions and OPERABILITY of the CEA position indicators are reqaired to be verified on a nominal basis of once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> with more frequent verifications required if an automatic monitoring channel is inoperable.
These verification frequencies are adequate for assuring that the applicabic LCOs are satisfied.
The surveillance requirements affecting CEAs with inoperable position ,
indicat.fon channels allow 10 minutes for test'ing each affected CEA.
limit was selected so that 1) the time would be long enough for the requiredTh testing, and 2) if all position indication were lost during testing, the ti e >
uould be short enough to allow a power reduction to 70", of maximum allo.;able thermal power within one hour from when the testing was initiated. The time <
