r e e DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGE The proposed Technical Specification change for Surry Units 1 and 2 revises Tables 3.8-1 and 3.8-2 which contain Containment Isolation Valves.

Two air-operated Phase I trip valves (TV-DA-103A, TV-DA-103B for Unit 1 and TV-DA-203A, TV-DA-203B for Unit 2) were installed on the Post-Accident Sample System return lines. These valves will reduce radiation levels outside containment should post-accident samples be required to be withdrawn from the

. reactor coolant system and containment sump. These modifications are required to meet the provisions of NUREG 0737, II.B.3, Post-Accident Sampling.

Manual isolation valves in the hydrogen analyzer system were replaced with ten (10) remote-manual valves (GW series valves) to upgrade the system. The remote-manual valves replaced manual valves located in high radiation areas which are inaccessible in post-accident conditions. The remote-manual valves will reduce personnel exposure following an accident.

One air operated trip valve was replaced with two direct acting solenoid valves (TV-SS-103A, TV-SS-103B for Unit 1 and TV-SS-203A, TV-SS-203B for Unit

2) in the Residual Heat Removal Sample line providing double isolation to increase assurance of reliable operation during accident conditions. The valves will be normally closed and receive a Phase I signal to ensure they are tripped closed on a safety injection signal. These modifications are required to meet the provisions of NUREG-0737, II.B.3, Post-Accident Sampling.

New instrumentation replaced the. servomanometer and valves in the leakage monitoring detection system used in Type "A" testing. The servomanometer and two air operated trip valves (TV-LMlOA, TV-LM-101B for Unit land TV-LM-201A, TV-LM-201B for Unit 2) no longer needed, were removed and the lines were capped to prevent leakage through these lines.

Typographical errors in valve numbers in Tables 3. 8-1 and 3. 8-2 are being corrected. The correct valve numbers for component cooling from air recirculatton are TV-CC-110 for Surry Unit 1 and TV-CC-210 for Surry Unit 2.

The correct valve number for the letdown isolation valve is TV-1204 for Unit 1 and TV-2204 for Unit 2. The correct valve number for primary grade water to pressurizer relief tank is TV-1519A for Unit 1 and TV-2519A for Unit 2. The correct valve number for inside isolation primary vent .pot is 2-VA-9 for Unit

2. The correct valve number for RS HX SW Drain is 1-SW-206 for Units 1 and 2.

An administrative error common

  • to Table 3. 8-1 and Table 3. 8-2 is being corrected by adding an asterisk (*) to the check valves (FP-153, Sl-224, Sl-225, Sl-226, Sl-227, Sl-228, Sl-229) that are not Type "c" tested. The asterisk(*), which specifies Type "C" testing not required, was inadvertently left off when the valves were placed in the Tables.

Other administrative errors being corrected for Surry Unit 2, Table 3.8-2 are as follows:

a) Valve 2-IA-446, a Unit 1 containment isolation valve incorrectly included in Table 3.8-2, is being removed. The correct corresponding isolation valves for Unit 2 are l-IA-704 and 2-IA-704 which are being added to Table 3, 8-2. Valve 2-IA-446 is also incorrectly listed in the check valve section. The correct corresponding Unit 2 check valve, 2-IA-868, is being added.

b) Valve 2-IA-938, a Unit 1 containment isolation valve incorrectly included in Table 3.8-2, is being removed. The correct corresponding Unit 2 isolation valve, 2-IA-864, is being added.

JI .

. e e c) Valves 2-IA-938, a Unit 1 containment isolation valve incorrectly included in Table 3.8-2, is being removed. The correct corresponding Unit 2 isolation valve, 2-IA-864, is being added.

d) Valves 2-SA-60 and 2-SA-62 are not containment isolation valves and*

are being removed from Table 3.8-2. The correct Unit 2 Service Air Containment isolation valves, 2-SA-81 and 2-SA-82, are being added to Table 3.8-2. Although not listed in Table 3.8-2, valves l-IA-704, 2-IA-704, 2-IA-868, 2-IA-864, 2-SA-81, and 2-SA-82 have been Type "C" tested.

Other administrative errors being corrected for Surry Unit 1, Table 3.8-1 are as follows:

a) Manual valves 2-IA-446 and l-IA-446, incorrectly listed in check valve section of Table 3.8-1, are being removed.

b) Valve l-IA-939 listed twice.

c) Valve l-SA-446 is not an isolation valve and is being removed from Table 3.8-1.
