CY-98-084/ Attachment 3/Page 1 Description of Chance l The proposed change will delete Technical Specification 3.3.3.3, " Seismic Instrumentation"in accordance with the guidance contained in Generic Letter 95-10'. In accordance with the Generic Letter this material will be deleted from the Technical 3 Specifications and is being transferred to the Technical Requirements Manual (TRM). i The TRM is a document that is controlled by CYAPCO procedures. Any change to the I TRM requires that a review be conducted in accord >nce with the requirements of 10CFR50.59. This material will be relocated verbatim to the TRM with the exception of section, table and reference numbers, the correction of a typographical error discussed

' below, updating to reflect the new equipment, and to account for formatting differences.

l- The following information will be transferred to the TRM:

-3/4.3.3.3 SEISMIC INSTRUMENTATION TABLE 3.3-5 SEISMIC MONITORING INSTRUMENTATION TABLE 4.3-4 SEISMIC MONITORING INSTRUMENTATION SURVEILLANCE REQUIREMENTS

'In October 1997, it was concluded that in Technical Specification Table 3.3-5, the I Triaxial Servo Accelerometer (SSA-302) located on the basemat in the Cable Vault which had a measurement value of "O to 0.59" with no units associated with the values was incorrect. An evaluation established that per the vendor (Terra Technology)-

manual the correct range is 0.5g. Thus, this appears to be a typographical error, where the "g" was interpreted to be a "9" (i.e., 0.5g vs. 0.59). Therefore, in transferring Table 3.3-5 to the TRM, "O to 0.59" will be changed to " 0.5g".

In addition, CYAPCO will update the tables in the TRM to reflect the new seismic

. monitoring instrumentation once the transfer is complete.

l The use of the TRM to control material which has been relocated from the Technical 2

Specifications has been previously authorized by the NRC . . Currently the Haddam Neck Plant maintains, among other topics, information on fire protection, which has (1) . NRC Generic Letter 95-10, " Relocation of Selected Technical Specifications  ;

Haddam Neck Plant Proposed Revision To The Technical Specifications Safety Assessment And No Significant Hazards Consideration Safety Assessment l

The plant has permanently ceased operations, the reactor has been permanently i defueled, and the spent fuel is stored in the spent fuel pool.

Section Vl(a)(3) of Appendix A to 10CFR100 requires that seismic monitoring l instrumentation be provided to promptly determine the response of those nuclear power plant features important to safety in the event of an earthquake. This capability is required to allow for a comparison of the measured response to that used in the design basis for the unit. Comparison of such data is needed to (1) determine whether the L plant can continue to be operated safely and (2) permit such timely action as may be appropriate. However, seismic instrumentation does not actuate any protective equipment or serve any direct role in the mitigation of an accident.

L The capability of the plant to withstand a seismic event or other design basis accident is determined by the design and construction of systems, structures, and components.

The instrumentation is used to alert operators to the seismic event and evaluate the plant response. The NRC's Final Policy Statement on Technical Specification improvements (SECY-93-067) stated that instrumentation to detect precursors to

, ' reactor coolant pressure boundary leakage, such as seismic instrumentation, is not i included in the first criterion. As discussed above, the seismic instrumentation does not serve as a protective design feature or part of a primary success path for events which

challenge fission product barriers. The NRC staff, in Generic Letter 95-10, has

( concluded that the seismic monitoring instrumentation does not satisfy the 10CFR50.36

' criteria and need not be included in the technical specifications.

i f This material is being transferred to the Technical Requirements Manual (TRM). This transfer, is 'in accordance with Generic Letter 95-10m and is consistent with the Standard Technical Specifications for Westinghouse Plants (WOG STS) provided in

o. NUREG-1431.(2) The relocation of this information to the TRM will continue to provide adequate control over this equipment to ensure its continued opere aility.

. U. S. Nucl:ar Regulatory Commission CY-98-084/ Attachment 4/Page 2 In summary, the changes do not have an effect on the safety of the plant. These l changes will result in the relocation to the TRM of the seismic monitoring technical specification, modified to address the new section, table, reference numbers and equipment, the correction of a typographical error, and to account for formatting differences. Thus no..s of the above changes affect plant configuration nor do they affect plant operations. Therefore, the changes do not affect the safety of the plant.

> U. S. Nucle:r Regulatory Commission CY-98-084/ Attachment 4/Page 3 Significant Hazards Consideration CYAPCO has reviewed the proposed changes to the Technical Specifications in accordance with 10CFR50.92 and concluded that the changes do not involve a significant hazards consideration (SHC). The basis for this conclusion is that the three criteria of 10CFR50.92(c) are not compromised. The proposed changes do not involve

. an SHC because the changes would not:

1. Involve a significant increase in the probability or consequences "f an accident l previously evaluated.

As a result of the present plant configuration which has the fuel permanently l removed from the reactor, the reactor-related accidents previously evaluated (i.e., LOCA, MSLB, etc.) are no longer possible. The accidents previously evaluated that are still applicable to the plant are fuel handling accidents and L gaseous and liquid radioactive releases.

l . There is no significant increase in the probability of a fuel handling accident since

! refueling operations have ceased. In fact, there is a decrease in probability of a fuel handling accident since the need to move / rearrange fuel assemblies is minimal until they are removed from the spent fuel pool (i.e., for dry cask storage or for transferring to USDOE possession). In addition, the consequences of a fuel handling accident are continuing to decrease since the fuel in the spent fuel poolis continuing to decay.

The radiological consequences of a gaseous or liquid radioactive release are bounded by the fuel handling accident during defueled operation and a spent l resin fire during the reactor coolant system decontamination. With the plant defueled and permanently shutdown, the demands.on the radwaste systems are

. lessened since no new radioisotopes are being' generated by irradiation or-fission. - Therefore, there is no increase in the probability or consequences of a gaseous or liquid radioactive release. .

The ability of the plant to withstand a seismic event is not affected by this proposed change. The seismic instrumentation does not actuate any protective

- equipment or serve any direct role in the mitigation of an accident. The equipment will continue to be adequately controlled by the TRM to ensure operability and alert operators to a seismic event, should one occur, so that appropriate actions can be taken. Therefore, there is no increase in the l consequences of a seismic event.

t-This material is being transferred to the TRM. This transfet is in accordance with I: - Generic Letter 95-10W and is consistent with the WOG STS provided in 1 NUREG-1431.* .The removed material included in this category is Technical  :

Specification 3/4.3.3.3 and the related tables.

e U. S. Nuclear Regulatory Ocmmission CY-98-084/ Attachment 4/Page 4 Based on the above, the proposed changes to the Technical Specifications do not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Create the possibility of a new or different kind of accident from any accident previously evaluated.

There is no change in how spent fuel is stored or moved in the spent fuel pool.

Therefore, the postulated fuel handling accidents are still bounding and are still considered as credible postulated accidents.

1 There is no change in the design and construction of plant systems, structures and components with respect to the capability to withstand a seismic event.

Therefore, the currently assumed radioactive releases are still bounding.

This material is being transferred to the TRM. This transfer is in accordance with 0 3 Generic Letter 95-10 ) and is consistent with the WOG STS provideJ in NUREG-1431.(2) The removed material included in this category are Technical Specification 3/4.3.3.3 and the related tables.

Based on the above, the proposed changes to the Technical Specifications do not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Involve a significant reduction in a margin of safety.

The capability of the plant to withstand a seismic event or other design basis accident is determined by the design and construction of systems, structures, and components. The instrumentation is used to alert operators to the seismic event and evaluate the plant response. The NRC's Final Policy Statement on Technical Specification improvement (SECY-93-067) stated that instrumentation to detect precursors to reactor coolant pressure boundary leakage, such as seismic instrumentation, is not included in the first criterion. As discussed above, the seismic instrumentation does not serve as a protective design feature or part of a primary success path for events which challenge fission product barriers. The NRC staff, in Generic Letter 95-10, has concluded that the seismic monitoring instrumentation does not satisfy the 10CFR50.36 criteria and need not be included in the technical specifications.

This material is being transferred to the TRM. This transfer is in accordance with 0
