Dear Ms. Adensam:

NUCLEAR PLANT NO. 2 RE(UEST FOR AMENDMENT TO TECHNICAL SPECIFICATIONS

,FOR H202 ANALYZERS (SECTION 4.3.7.5)

In accordan'ce with the Code of Federal'Regulations, Title 10, Parts 50.90 and 2. 101, the Supply System hereby requests an amendment to the WNP-2 Technical Specifications. Specifically, the, following change is requested:

Modify Table =4.3.7,.5-1, Table Notations, for Accident Monitoring Instrumentation Surveillance Requirements (as attached).

License Condition '16, Attachment 2, item 3(a) to the WNP-2 Operating License states that "The licensee shall implement (installation or upgrade) requirements of R.G. 1.97 Rev. 2 with the exception of flux monitoring prior to startup following the first refueling outage."

As a result, during the Spring 1986 outage the Supply System will be replacing, in total, the present H 0 Analyzers with a qualified replacement. The re-placement system is desighed so that precise sample gas concentrations as described in the present technical specification are not necessary to ensure coverage of the required instrument range. 'ccordingly, as supported below, reference to precise sample gas concentrations should be removed from the subject technical specifications.

E. G. Adensam Page Two RE(VEST FOR AMENDfiENT TO TECH. SPECS. FOR H202 ANALYZERS (SECTION 4.3.7.5)

The new H 02 monitoring system has a micro-processor that automatically compensates for containment pressure and temperature and is used to calibrate the H20 monitoring system. An actual Technical Specification restraint is no l(nger required on the calibration gas concentrations since changes in H or 02 calibration gas concentrations are entered into the micro-professor and directly compared to the compensated output signals of the H2 and 02 sensors during calibrations.

The Supply System has reviewed this change per 10 CFR 50.59 and determined that no unreviewed safety questions will result from this amendment. Addi-tionally, this change has been reviewed per 10 CFR 50.92 and it does not:

1) Involve a significant increase in the probability or consequences of an accident previously analyzed because deletion of a precisely specified gas concentration does not detract from the ability of the new H 02 analyzers (Exosensor) to cover the required instrument range. Tie new system's capabilities, without a precisely specified gas concentration in the technical specification, remain equivalent to the present system. Therefore, no increase in probability or consequences of a previously analyzed accident is credible.

2) Create the possibility of a new or different kind of accident because no function or features of the present system will be lost in cali-brating the new system w'ithout the precise gas concentrations specified in the technical specifications. Hence, no new or different kind of accident is conceivable.

3) Involve a significant reduction in a safety margin because the new system without precisely specified gas concentrations has the same capabilities of the presently installed system. Hence, no reduction in safety margins is possible.

The new system represents a marked improvement over the presently installed system. The sample points and return lines have been relocated eliminating sample return problems and increasing the accuracy and confidence of sample results. Remote calibration at any time is a new feature over the present system. Additionally, the new system utilizes hydrogen/argon calibration gases instead of the more flammable hydrogen/nitrogen calibration gases used by the present system. The micro-processor utilized with the new system eliminates the need for precise gas concentrations, provides greater flexibility, and with the design features discussed above, provides a significant increase in system operability and overall safety.

This change has been reviewed by the Plant Operations Committee and the Supply System Corporate Nuclear Safety Review Board.
