~ ~ Shift Technical Advisor A descrxptxon of our original STA program was outlined in a letter, dated October 17, 1979, from L. D. White, Jr. to Mr. Dennis Ziemann, with additional information .
provided in a letter dated December 28, 1979, from Mr. White to Mr. Ziemann. In response to the NRC's letter dated July 7, 1980, from Mr. Dennis Crutchfield we provided additional clarification of our original STA program and a description of our new STA program in a letter dated August 5, 1980 from L. D. White, Jr. to Mr. Crutchfield.
Our original STA program utilized licensed operators and included their participation in college-level engineering courses to provide them eventually with an engineering degree. At the request of the NRC RG&E modified the original program and assigned either degreed engineers or SRO's as STA, and assigned degreed engineers to perform the Operational Assessment function.
We began staffing the Operational Assessment, Group in the summer of 1980.
Our STA training and requalification program is described by a Ginna Station Administrative Procedure, and consists of various phases as described below.
Present Level of Trainin Initial training to meet the requirements listed in Harold Denton's letter dated October 30, 1979 to All Operating Nuclear Power Plants has been completed.

Atoms and Matter Light and Electromagnetic Waves Radioactivity and Particle Behavior Nuclear Reactions Fission Reactor Fundamentals Nuclear Fission of Uranium - 235 Neutrons, Reactions, and Moderator Effects Neutron Multiplication Factors Reactivity Reactor Kinetics The Subcritical Reactor On-the-job training, including continuing assignment on-shift as STA, has provided a basic familiarization in plant systems and operation.
Additional Trainin Expanded training for the calendar year 1981 will include:
Plant Design System Operation Transient Response Accident Analysis Simulator Training Procedure Review Technical Specifications Management Skills
Requalification training will commence January 1, 1982, and will continue on a two-year frequency (or until the STA program is phased out). This program will include:
Procedure Review Transient Response Accident Analysis On-shift assignment as STA or on-shift assignment as SRO Evaluations by the Technical Assistant for Operational Assessment Lon -Term STA Pro ram and Trainin Plans The long-term STA program will continue to utilize degreed individuals (with the supplemented education, experience, and training listed above), or individuals with an SRO license who have received the necessary technical education and training. We will replace degreed individuals with SRO-licensed individuals as the licensed individuals receive education'imilar to that outlined in RG&E's letter dated December 28, 1979 from L. D. White, Jr. to Mr. Dennis Ziemann.
The STA program will be phased out when the man-machine interface control room review has been completed and the shift supervisor and senior operator on a shift each meet the proposed future educational requirements of approximately 60 technical credit hours for SRO licensing.
STA Selection and uglification If replacement STA's are required, screening will be performed to ensure candidates meet the education, experience and training requirements of our Administrative Procedure for STA Training prior to their assignment as STA.
Comments on INPO Document and Com arison with RG&E's RG&E has reviewed INPO's document of April 30, 1980 concerning STA Qualifications, Education and Training.
We have concluded that these INPO goals for the STA are "standards of excellence" and represent an ultimate goal. However, lacking guidance from the NRC on minimum requirements for STA, RG&E has established minimum requirements for'TA, independent of INPO's "standard of excellence".
i' We are pleased to offer our comments on the above-mentioned INPO document. We fully endorse the comments and recommendations made by the Mid-Atlantic Nuclear Training Group (MANTG) in a letter, dated October 21, 1980, from MANTG (Young) to INPO (Thomas) and quoted below:
General It is the opinion of the members of the Mid-Atlantic Nuclear Training Group that the subject document's experience, education, and training requirements do not appear to be based upon the demands of the STA position.
As an example, the document includes a position description which lists twelve typical STA responsibilities. Of these, four pertain to evaluating plant conditions during transients or investigating the causes of such very little emphasis is placed on transient conditions transients'et, in the transient/ accident analysis and Emergency Procedures requirements of Section 6.7.
The MANTG recommends that all experience, education, and training requirements be based upon a detailed job/task analysis'hen derived in this manner, the standards will be able to relate to specific knowledge levels, requirements to the typical STA responsibilities. This approach seems especially prudent in light of the recent emphasis of job and task analysis by the Nuclear Regulatory Commission, American Nuclear Standards Institute, and the Institute of Nuclear Power Operations.
- 2. Pa e 10, Section 5.2 E erience
- a. The first paragraph requires the STA to have a minimum of 18 months of nuclear power plant experience.
The MANTG recommends that this requirement be deleted.
It is our opinion that an effective training program will produce a competent STA, regardless of his previous experience.
It should be noted that INPO did not publish this requirement, even in draft form, until May of this year. With the NRC requiring fully trained STA's by January 1, 1981, it will be impossible to staff the STA position with personnel who meet both the require-ments of the NRC and INPO, unless they are drawn from the existing plant staff.
- b. Paragraph three states that a maximum of three months of training may be applied toward the experience requirement. The MANTG recommends that both on-the-job training and plant specific systems or operations train-ing which is conducted by or for the facility at which the STA is qualifying, be equivalent to experience on a one-to-one basis with no maximum. The rationale for
l 10 this recommendation is that training at the plant provides the trainee the opportunity to trace systems and observe plant operations which the MANTG feels fulfills the intent of this section.
C. The MANTG recommends that the INPO include a provision in Section 5.2 which equates cold license simulator training to operating plant experience on a three to one basis, similar to the provision presently allowed for cold license operator candidates'a e ll Section 5.3 Absence from STA Duties MANTG recommends that personnel not actively performing STA functions but participating in the STA requalification program, be exempt from the requirements of this section.
Additionally, those persons not performing the function nor participating in the requalification program be required to complete only those portions of the requalification program which they have missed during their absence prior to assigning them for STA duty.
Pa e 13, Section 6.1.2 Colle e Level Fundamental Education
- a. In the Electrical Sciences section, the MANTG recommends that Circuit Theory and Digital Electronics be deleted from the knowledge requirements. The MANTG does not believe that they are pertinent to the understanding of nuclear power plant response or control.
- b. MANTG requests guidance on how to obtain this college level knowledge within the short time frame required by the Nuclear Regulatory Commission.
Pa e 15, Section 6.2 A lied Fundamentals-Plant
~Secific The MANTG requests guidance on how to determine what constitutes college level training for Plant Specific topics.
Pa e 17, Section 6.6 General 0 eratin Procedures MANTG recommends that all plant operating procedures which relate to an STA's function be included in this section rather than those as mentioned. These procedures should be identified in the STA task analysis recommended in paragraph 1.
1 I \ 1 C F
- 8. Pa e 18, Section 6.8 Simulator Trainin The first paragraph requires a trainee/ instructor ratio of not more than four to one. This would seem to require at least two instructors for every training session since it is anticipated that STA's will be trained along with the rest of their control room watch section. The MANTG recommends that a 4:1 ratio only apply when only STA's are being instructed in a given course.
- b. The HANTG recommends that simulator emphasis include the discussion and demonstration of those actions which operators may take which would either mitigate or aggrevate a transient or accident condition.
- 9. Pa e 19, Section 6.9 Annual Re ualification Trainin MANTG recommends that a review of the theoretical material presented during STA qualification be included in the requalification program.

~ ~ ~ Shift ~
Manning BY letter dat ed December 15, 1980 from L. D. White, Jr.
to Mr. Dennis M. Crutchfield, USNRC, RG&E responded to shift staffing criteria and guidelines for scheduling overtime for licensed operators. The commitments pro-vided in that letter, and proposed alternatives to some of the Staff overtime guidelines, remain unchanged. We have revised administrative procedures to implement a similar'olicy to limit overtime work of people in addition to licensed operators who perform safety related work. Procedure A52.9 has been revised to in-clude limits on overtime worked by auxiliary operators in addition to SROs, ROs and Shift Technical Advisors.
Procedure A52.10 has been implemented to limit overtime worked by health physicist technicians, I&C technicians and key maintenance personnel.
Guidance for the Evaluation and Development of Procedures for Transients and Accidents The Westinghouse Owners Group will submit by January 1, 1981, a detailed description of our program to comply with the requirements of Item I.C.1. The program will identify previous Owners Group submittals to the NRC, which we believe will comprise the bulk of the response.
1 pl I
12 Additional effort required to obtain full compliance with this item (with proposed schedules for completion) will also be identified, as discussed with the NRC on November 12, 1980.
Design Review of Plant Shielding and Environmental Qualification of Equipment for Spaces/Systems Which May Be Used in Post-Accident Operations.
A discussion of our design review is contained in a letter dated December 28, 1979 from L. D. White, Jr. to Mr. Dennis Ziemann, USNRC. Additional information and schedule are contained in a letter dated December 15, 1980 from John E. Maier to Mr. Dennis M. Crutchfield, USNRC.
II.E.1.2 Auxiliary Feedwater System Automatic Initiation and Flow Indication Part 1: Auxiliary Feedwater System Automatic Initiation RG&E has previously responded to NRC requirements for auxiliary feedwater systems in letters dated November 28, 1979, December 14, 1979, December 19, 1979, March 28, 1980, May 22, 1980, May 28, 1980 (2 letters) and July 14, 1980. No changes to the requirements have been identified which require additional information.
Part 2: Auxiliary Feedwater System Flowrate Indication The Design Criteria and Flow Diagram for the modification of the Auxiliary Feedwater Flow Indication is provided in Appendix A. Some of the salient features of the design are:
Redundant flow indication is provided for each motor driven auxiliary feedwater pump (MDAFP) and the common discharge of the turbine driven auxiliary feed-water pump (TDAFP).
- 2. Each redundant channel of flow indication consists of a: 1) qualified transmitter, 2) transmitter power supply, 3) square root extractor, 4) output isolation amplifier, and 5) main control board analog indicator.
- 3. Indication is provided to the Operator by means of a dual movement vertical scale indicator. Each move-ment receives the analog signal from its respective channel of flow indication for a particular
A N

13 auxiliary feedwater flow path. Hence, the Operator can quickly ascertain between channels.
if there is any discrepancy
- 4. Each channel of flow indication is powered from a separate battery-backed vital instrument bus. In addition, each flow channel's analog instrumentation is mounted in a fully qualified instrument rack.
- 5. Testability features have been provided in the design, including local flow indication near the auxiliary feedwater pump that will facilitate periodic loop calibration.
- 6. The Ginna Station Quality Assurance Program will be utilized in the design, procurement, installation and testing of this modification.
- 7. As mentioned in paragraph 3 above, continuous display of both channels of flow indication will be provided to the operator on the main control board.
- 8. The flow transmitters installed as a part of this modification are included in Rochester Gas and Electric's program of Environmental Qualification of Foxboro Transmitters being conducted by RG&E and a number of other utilities, and will be qualified to the requirements of NUREG-0737.
II.E.4.2 Containment Isolation Dependability The purge and vent system at, Ginna consists of four 48 inch isolation valves. The Staff's interim position on containment purging (now called Position 6) was im-plemented on these valves by our December 14, 1979 and May 29, 1980 letters. During a recent review of Position 6, it was postulated that two 6 inch valves on our con-tainment depressurization line may be interpreted as falling under Position 6 requirements. These valves are not used for containment purge and vent operations but are used periodically to equalize pressure between inside and outside containment.
Preliminary analysis supplied by the vendor of these valves indicates that the most severe flow condition loading will not stress the valves beyond their standard design limits. The analysis also demonstrates that the valves will close as fast or faster with flow than with-out flow., Therefore, no restrictions need be placed on valve position, but an interim restriction will be placed on the amount of time these valves are open until the final analysis is complete.
PP A valve qualification program for these 6 inch valves will be done in two phases:
To provide further assurance of valve operability following post-accident closure, a more detailed analysis will be performed.
The second phase will consist of seismic and environmental qualification of the entire valve and actuator assembly.
We will inform you of the results upon their completion.
The depressurization valves will only be used to equalize pressure between inside and outside containment, to prevent an unacceptable buildup of containment pressure during normal operation. Whenever containment depressurization is required, emphasis will be placed on limiting de-pressurization times to as low as practical. We do not have at this time sufficient operating experience with limited depressurization to predict what containment pressure fluctuations may occur during plant operation
,to commit to a specific depressurization time limit.
However, all practical efforts will be made to limit depressurization times to the 90 hour0.00104 days <br />0.025 hours <br />1.488095e-4 weeks <br />3.4245e-5 months <br /> per year goal while critical. Should this goal be exceeded, we will inform you and provide a summary of the reasons for exceeding the 90 hour0.00104 days <br />0.025 hours <br />1.488095e-4 weeks <br />3.4245e-5 months <br /> goal.
The containment isolation pressure setpoint will be reduced to 4 psig. Our revised operation for contain-ment depressurization may result in containment pressures of 2 psig. Normal instrument errors and drift may amount to as much as 1 psig (~1% of range). An addi-tional 1 psig margin should be added to assure that in-advertent isolation of containment does not take place since this same signal also trips the reactor and starts safety injection. We will continue to monitor containment pressure. it If is feasible to reduce the 4 psig setpoint pressure, we will inform you.
Noble Gas Effluent Monitor Information concerning our plans for monitoring noble gas effluents was contained in a letter dated December 15, 1980 from John E. Maier to Mr. Dennis M. Crutchfield, USNRC. Additional information will be provided by February 1, 1981.
'h 15 II.F.1.3 Containment High Range Radiation Monitor A Victoreen Model 875 High Range Containment Area Monitor System has been purchased for installation by January 1, 1982. The system is currently being qualified to IEEE-323 and Regulatory Guides 1.97 and 1.89, with test reports expected to be completed by March 1981.
Until those tests are complete, however, we cannot commit that the installed system will meet all of the NRC requirements.
II.F.1.4 Containment Pressure Monitor The Staff position presently calls for "continuous recording" of containment pressure; it is felt that this would result in a waste of paper and unnecessary wear on the recorder mechanism. A system is proposed, however, that will start recording whenever a safety injection or containment isolation signal is present.
This proposed system will provide adequate recording of signals.
II.F.1.5 Containment Water Level Monitor Information concerning RG&E plans to install containment water level instruments is contained in RG&E letters dated December 15, 1980 from John E. Maier to Mr. Dennis Crutchfield and November 19, 1979 from L. D. White, Jr.
to Mr. Dennis Ziemann.
Instrumentation for Detection of Inadequate Core Cooling RG&E's position concerning inadequate core cooling instru-mentation is contained in letters dated December 15, 1980 from John E. Maier to Mr. Dennis Crutchfield and July 2, 1980 from L. D. White, Jr. to Mr. Crutchfield.

~ ~ ~
Injection on Vessel Integrity for Small-Break Loss-of-Coolant Accident with No Auxiliary Feedwater To completely address the NRC requirements of detailed analysis of the thermal-mechanical conditions in the reactor vessel during recovery from small breaks with an extended loss of all feedwater, a program will be completed and documented to the NRC by the Westinghouse Owners Group by January 1, 1982. This program will consist of analysis for generic Westinghouse PWR plant groupings.
Following completion of this generic program, additional plant specific analyses, if required, will be provided.
A schedule for the plant specific analysis will be determined based on the results of the generic analysis.
II.K.2.17 Potential for Voiding in the Reactor Coolant System during Transients The Westinghouse Owners Group is currently addressing the potential for void formation in the Reactor Coolant System (RCS) during natural circulation cooldown condi-tions, as described in Westinghouse Letter NS-TMA-2298 (T. M. Anderson, Westinghouse to P. S. Check, NRC). We believe the results of this effort, will fully address the NRC requirement for analysis to determine the potential for voiding in the Reactor Coolant System during anticipated transients. A report describing the results of this effort will be provided to the NRC before January 1, 1982.
II.K.2.19 Sequential Auxiliary Feedwater Flow Analysis The Transient Analysis Code, LOFTRAN, and the present, small break evaluations analysis code, WFLASH, have both undergone benchmarking against plant information or experimental test facilities. These codes, under appropriate conditions, have also been compared with each other. The Westinghouse Owners Group will provide on a schedule consistent, with the requirement of Task II.K.2.19, a report addressing the benchmarking of these codes.

Relief Valve Isolation System And II.K.3.2 Report on Overall Safety Effect of Power-Operated Relief Valve Isolation System The Westinghouse Owners Group is in the process of developing a report (including historical valve failure rate data and documentation of actions taken since the TMI-2 event, to decrease the probability of a stuck-open PORV) to address the NRC concerns of Item II.K.3.2.
However, due to the time-consuming process of data gathering, breakdown, and evaluation, this report is scheduled for submittal to the NRC on March 1, 1981. .As required by the NRC, this report will be used to support a decision on the necessity of incorporating an automatic PORV isolation system as specified in Task Action Item II.K.3.1.
II.K.3.5 Automatic Trip of Reactor Coolant Pump During Loss of Coolant Accident The Westinghouse Owners Gro'p resolution of this issue has been to perform analyses using the Westinghouse Small Break Evaluation Model WFLASH to show ample time is available for the operator to trip the reactor coolant pumps following certain size small breaks (See WCAP-9584). In addition, the Owners Group is supporting a best estimate study using the NOTRUMP computer cod'e to demonstrate that tripping the reactor coolant pump at the worst trip time after a small break will lead to acceptable results.
For both of these analysis efforts, the Westinghouse Owners Group is performing blind post-test predictions of LOFT experiment L3-6. The input data and model to be used with WFLASH on LOFT L3-6 has been submitted to the Staff on December 1, 1980 (NS-TMA-2348). The information to be used with NOTRUMP on LOFT L3-5 will be submitted prior to performance of the L3-6 test as stated in Westinghouse Owners Group letter OG-45 dated December 3, 1980.
The LOFT prediction from both models will be submitted to the Staff on February 15, 1981 given that the test is performed on schedule. The best estimate study is scheduled for completion by April 1, 1981.
Based on these studies, the Westinghouse Owners Group believes that resolution of this issue will be achieved

II.K.3.12 Confirm Existence of Anticipatory Reactor Trip Upon Turbine Trip An anticipatory trip upon reactor trip exists at the R. E.
Ginna plant as shown in drawing 882D612, Sheet 2, Revision 3 and Sheet 3, Revision 2, provided with a letter dated January 18, 1979 from L. D. White, Jr. to Mr. Dennis Ziemann.
II.K.3. 17 Report on Outages of Emergency Core Cooling Systems Information on ECCS equipment outages is contained in Table II.K.3.17. The information in Table II.K.3.17 was compiled in response to Mr. D. G. Eisenhut's May 7, 1980 letter concerning Five Addition TMI Items and does not include the corrective action taken, a recent change in the requirements. Nevertheless, as seen from the table, most. outages were the result of routine maintenance and inspections. In cases where a violation of Technical Specifications did occur, the corrective action taken is documented in Licensee Event Reports filed with NRC. We have reviewed the ECCS equipment outages and determined that. no action is required at this time. Malfunctioning steam admission valves, the cause of lengthy turbine-driven auxiliary feedwater pump outages, were replaced in May, 1980.
Improving Licensee Emergency Preparedness - Long Term At this time'e believe we will be able to comply with the implementation schedule established for this item.
However, we plan to comply with the requirement for a prompt notification system primarily with the installa-tion of sirens. We do not yet have a commitment for supply of the sirens because field work necessary to establish sound levels, siren locations and the number of sirens required is not yet completed. If it becomes necessary to request an extension of the implementation
' date as this work proceeds, we will notify you promptly.
4 19 The emergency plans required to be submitted by January 2, 1980 concerning radiological emergency response plans will be provided by separate correspondence.
III.D.3.4 Control Room Habitability Requirements The information requested in Attachment 1 to item III.D.3-4 is not being submitted by January 1, 1981 for the reasons given in a letter dated November 24, 1980 from L. D. White, Jr. to Mr. Dennis M. Crutchfield, USNRC.

Desi Criteria 1.0 Summar Descri tion of the Desi Summary 1.1.1 The purpose of this modification is to upgrade the flow and pressure instrumentation associated with the motor driven and turbine driven auxiliary feedwater pumps at Ginna Station. This modification involves the replace-ment of the following primary instrumentation: PT-2029, FT-2001, FT-2009, PT-2019, PT-2030, FT-2002, FT-2006, FT-2007. This instrumentation presently used does not, have the desired accuracy and repeatability.
1.1.2 In addition, the existing flow transmitters are utilized to operate valves 4007, 3996 and 4008. Each of these flow transmitters have a built in switch which is actuated via a mechanical linkage. This mechanical linkage has enough inertia such that accurate and repeatable determination of switch actuation point is not possible. As part of this modification, these switches will be replaced with electronic bistables, which electronically compare flow transmitter output with setpoint and change 'state when the setpoint is reached.
To satisfy the requirements of reference 2.5 below, additional channels of flow instrumentation will be added to each auxiliary feedwater pump. This additional channel will be of the opposite channel designation from that of the primary channel. The primary channel for each feedwater pump will control that particular pump's discharge valve, whereas the secondary channel merely indicates flow. The secondary channel as shown on the above referenced consists of that instrumentation without tag numbers.
1.2 Functions (Reference RGSE drawing 33013-697, t
Rev. 0) 1.2.1 Poop FT-2001 This loop measures the flow in auxiliary feedwater line to the "A" steam generator, The differential pressure measured by FT-2001 is converted to a flow signal by .
FM-2001. Indication of flow on the main control board is provided by FI-2021A. FM-2001A acts as an isolation amplifier to isolate the class IE system from FI-2021B which is not safety related. Electronic bistable FY-2001 functions to position valve 4007 such that the flow matches FY-2001's setpoint. FQ-2001 supplies dc power to this loop.

1.2.2 Loop FT-2009 This loop measures the total discharge flow of the steam driven auxiliary feedwater pump. FT-2009 measures the differential pressure across its flow element and FM-2005 converts this signal to a flow signal. FY-2005 is an electronic bistable which opens recirc valve CV-27 to maintain minimum flow through the pump, during low flow operations. FM-2009A is an isolation amplifier which isolates local flow indicator FI-2009 from the Class IE safety system. FQ-2009 supplies this loop with dc power.
1.2.3 loop FT-2002 This loop functions exactly the same as the FT-2001 loop with the only difference that this loop monitors the flow of auxiliary feedwater to the B steam generator.
1.2.4 Loops FT-2006 and FT-2007 Both these loops function in the same manner; each loop measures the flow to its respective steam generator from the turbine driven auxiliary feedwater pump and indicates this flow on the main control board. An isolation amplifier for each loop isolates the class IE portion from the non safety local indication located near the turbine driven pump. Each loop also contains a dc power supply.
1.2.5 Loops PT-2029, PT-2019 and PT-2030 Each of these loops are similar and merely monitor the discharge pressure of their respective auxiliary feedwater pump. Indication of discharge pressure for each pump is on the main control board.
1.2.6 For loops FT-2001, FT-2009 and FT-2002 a secondary redundant channel of flow instrumentation is provided.
Each channel consists of a flow transmitter (FT),
sguare root converter (FM), power supply (FQ) and control room flow indicator (FI)..
1.3 Performance Reguirements The sensing elements (the flow and pressure trans-mitters) shall be capable of sensing and producing an output over the range of design values for all possible operating and accident conditions for the particular system in which they are installed.
