The Station Operations Review Committee has reviewed and concurs with these evaluations.

ITEM

SUMMARY

A.

Design Change Packages 2EC-3274 Pkgs 1&2 "Throttling Service Water Flow To No. 21 and 22 CCHX" - These change packages throttle the Service Water inlet isolation valves from the existing full open locked positions to partially open locked positions.

These particular valve positions will be established in the field and dependent on the existing CCHX's flow resistances.

These packages also address the throttling of Service Water inlet and outlet valves.

The inlet and/or outlet isolation valves may then have to be adjusted to compensate for +/- changes in CCHX flow resistance.

The Component Cooling HX operating procedures will also be revised to update the CCHX design outlet temperatures from 95 degrees to 99 degrees F.

Also, the compensatory actions imposed by Engineering Evaluation S-C-SW-MEE-0893, for SWS operation with river temperatures < 70 degrees F, will be removed from these procedures.

The Westinghouse analysis demonstrates that the proposed throttling of valve 21SW21, and valve 21SW355, if required, will assure adequate service water flow rate delivery to the CCHX under postulated accident conditions.

Calculation S-C-MDC-1317 shows that the proposed valve throttling during all modes of the plant operation will still ensure the original service water design flow rate of 10,000 gpm through the CCHX during all normal operating conditions.

Thus the acceptance criteria for licensing basis accidents and transients will continue to be satisfied and the existing safety margins will not be affected.

This DCP will not increase the consequences of a malfunction of a different type than any previously evaluated in the SAR.

The relay setting changes to the overcurrent relays of the 4.16KV vital bus incomer feeder and 4160/480-240 transformers will not reduce the margin of safety as defined in the basis for any Technical Specification.

(SORC 94-045)

"Deletion of RMS Channels 2R35 and 2R38" -

The purpose of this DCP is to perform modifications to remove Channels 2R35 and 2R38 from the RMS.

Detectors, check sources, and monitors are to be removed from the field.

Cables, conduits, and conduit supports are to be removed, rerouted, or spared in place.

2R35 and 2R38 are to be physically removed from the Interdata 7/32 communication loop.

The monitors to be removed are in the Steam Generator Blowdown Filter Loop, which is blind flanged out of service.

RMS Channels 2R35 and 2R38 are not included in the Technical Specifications, nor in the Bases for the Technical Specifications.

The monitors perform no function to mitigate radiation exposures at the site boundary, resulting from accidents described in the UFSAR, chapter 15.

Therefore, this modification does not reduce the margin of safety as defined in the bases for any Technical Specification.

(SORC 94-045)

"Caldon Ultrasonic Flowmeter Installation Test &

Experiment" -

The proposed modification to the facility is the installation of flow measurement test equipment on each of the four f eedwater pipes to the steam generators, and data recording equipment on the P-250 plant computer.

This equipment is being installed for the purpose of determining the current f eedwater flow rate to the steam generators, determining the present conditions of the feedwater flow nozzles, and providing a mechanism to trend performance and degradation of the system.

The reason for performing this test is

that f eedwater flow measurement was determined to be questionable as a result of review to Unit 2 Fuel Cycle 8 calorimetric and reactor Coolant System flow calculations.

This equipment will not be used as a primary method of controlling feedwater flow at this time.

Failure of the equipment will only result in the loss of data for the period of time the equipment is failed.

The Unit 2 Technical Specifications are primarily concerned with steam flow and feedwater flow mismatch with respect to steam generator water level control.

The proposed ultrasonic instrumentation is non-intrusive to the f eedwater mechanical and controls system and only provides data retrieval, storage and analysis.

However, the Honeywell transmitters will be installed in an intrusive manner, as they will be connected in parallel to existing transmitters.

The installation of these transmitters is controlled in a manner similar to the existing calorimetric transmitters, and will be implemented such that adverse effects on the f eedwater control and protection systems are minimized.

There are no changes to the facility introduced by the installation of either the ultrasonic instrumentation or the Honeywell transmitters used in this testing modification which would alter the performance of the f eedwater system as described in the Technical Specifications.

As such, the margin of safety has not been reduced. (SORC 94-045)

B. Temporary Modifications T-MOD #94-043 "Unit 2 Fuel Handling Building Ventilation System".

DCP 2EC-3242 provides design changes to the Fuel Handling Building exhaust fans 2VHE20 and 2VHE21, including (1) the replacement of backdraft dampers, flexible connections and adjustable motor sheaves, (2) the installation of duct mounted access doors on fan inlet ducts.

Normally both exhaust fans operate continuously along with the system supply fan 2VHE24. However, during the installation of DCP 2EC-3242, the Fuel Handling Area ventilation system

SUMMARY

50-311 SALEM 2 JUNE 10, 1994 R. HELLER (609)339-5162 will be taken out of service.

This T-MOD provides blanking plates on the ductwork downstream of the exhaust fan discharge backdraft dampers to ensure gaseous effluent from the Auxiliary Building Ventilation, Containment Pressure Relief and/or Waste Decay Tank does not'inadvertently enter Auxiliary Building, Elev. 100 1, while the required work is being performed as outlined in DCP 2EC-3242.

The Technical Specification requires that whenever irradiated fuel is in the storage pool, the fuel handling area ventilation system shall be operable.

In the event the system is not operable, all operations involving movement of fuel within the storage pool or crane operation with loads over the storage pool shall be suspended until the ventilation is restored.

During the temporary modification all fuel handling operations will be suspended in accordance with Technical specification 3/4.9.12 and procedure S2.0P-SO.FHV-00l(Q) and therefore the temporary modification will not requce the margin of safety as defined in the basis of the Technical Specifications.

(SORC 94-042)

The purpose of this proposal is to accept the discovered condition as-is, until the next refueling outage or forced outage of sufficient duration to correct with a design change package.

Each signal summator, 2PM-505B and 2PM-506B, uses the turbine impulse pressure signal to provide the setpoint to one protection channel of High Steam Line Flow Safety Injection (SI) comparators.

Signal summator PM-505B provides the setpoint signal for comparators FC-512, FC-522, FC-532, and FC-542 (Channel I).

Signal summator PM-506B, provides the FC-543 (Channel II, 221056).

These comparators provide the High Steam Line Flow SI signal to Reactor Protection Trains A and B.

The setpoint is reduced to 40%

steam flow once a reactor trip is sensed.

SI initiation results from High steam Line Flow (1/2 taken twice for four loops) together with either Low Low Tave to Low Steam Line Pressure.

SUMMARY

50-311 SALEM 2 JUNE 10, 1994 R. HELLER (609)339-5162 summators lose power, upon re-energizing these modules, the module output saturates high.

This output signal then provides a high steam flow reference setpoint to the High steam Line Flow comparators associated with this particular summator.

With this high setpoint, the associated comparators will never "see" a high steam line flow condition since the setpoint would be significantly greater than 110% steam flow value as defined by Technical Specifications.

The saturated summator output would also be prevented from reverting to the 40% value following a reactor trip.

This, in essence, removes all protective action provided by this summator and thus one of the two High Steam Line Flow protective channels for the period of time require by the summator to come out of saturation.

Both high steam flow channels are verified to be operable by quarterly channel functional testing.

In order to lose both channels of High Steamline Flow protection, multiple failure of equipment required operable by Technical Specifications would have to occur.

Since accident analyses are based on a single failure plus initiating event, the margins of safety demonstrated by the accident analyses remain valid.

"Plug, Stem and Cage Trim Assemblies" -

During the Unit 2 Seventh Refueling Outage, plug, stem and cage trim assemblies composed of 17-4 PM material were inadvertently installed in the Salem Unit 2 PORVs under DCP 2EC-3190.

The original intent of the DCP was to replace the installed trim assemblies composed of 17-4 PH stem and cage material and 304 SS-Stellite plug material with new trim assemblies composed of 420 SS plug and cage material and chrome-plated 316 SS stem material.

The purpose of this evaluation is to examine the existing condition and evaluate its acceptability for continued operation for the remainder of the current operating cycle.

The bases for Technical Specification 3/4.4.5 states that the PORV's function to relieve pressure during all design transients up to and

The bases for Technical Specification 3/4.4.10.3 states that the operability of the POPS ensures that the RCS cold legs are less than or equal to 212°F.

The PORVs will perform as designed with reasonable assurance and reliability and will remain capable of performing their specified functions for the current operating fuel cycle.

As a result, we conclude that the existing condition does not reduce the margin of safety as defined in the basis for any Technical Specification.
