Control of Combustible Gas Concentrations in Containment Following a Loss-of-Coolant Accident Project Position - The project complies with the requirements of Regulatory Guide 1.7 with the following clarification:

The discussion contained in Regulatory Guide 1.7 states that the NRC has concluded that a lower flammability limit of 4 volume percent hydrogen in air or steam-air mixtures is well established and is adequately conservative. Regulatory Position C.6 states that materials which would yield hydrogen gas due to corrosion from ECCS or containment spray should be identified and their use should be limited as much as practical. In USAR Section 6.2.5 regarding the Combustible Gas Control System, hydrogen production due to corrosion following a LOCA has been evaluated based upon the analyses performed considering the amount of hydrogen producing materials allowed in containment by design. The specific quantities of hydrogen producing materials used in evaluating CPS conformance to Regulatory Guide 1.7 are listed in Table 6.2-49, and the resulting hydrogen concentrations as a function of time are exhibited in Figures 6.2-130a and 6.2-130b. CPS procedures and design baseline documentation ensure the limitation of postulated post-LOCA hydrogen concentrations inside containment and drywell in accordance with Regulatory Guide 1.7.

Personnel Selection and Training Project Position - The project complies with the requirements of Regulatory Guide 1.8 with the following clarifications and exceptions: 1.

Reference:

Paragraph C.3.a, C.3.b, and C.3.c - Exception is taken to the requirement of minimum qualifications for individuals that direct or supervise the conduct of individual preoperational tests and startup tests, and individuals who review and approve preoperational and startup test procedures or results.

Instead, the following program will be used to qualify individuals: In order to ensure that the various Startup Group activities are performed by qualified personnel, three levels of qualifications are established: a. Level I

b. Level II

c. Level III The qualification levels required to perform specific startup organization activities is in accordance with the following table:

NOTE 1. The checkout and initial operation (C&IO) phase is a period during which checkout and testing is completed which is prerequisite to subsequent preoperational or acceptance tests. 2. The preoperational phase is a period during which preoperational test procedures (PTP's) and acceptance test procedures (ATP's) are performed. These tests, in general, are conducted on an integrated system or subsystem basis to verify that systems are capable of operating in a safe and efficient manner compatible with system design bases. By definition, "preoperational tests" are performed on nuclear safety-related systems. 3. The startup phase is that period beginning with preparations for fuel loading and extending through warranty tests.Startup test procedures (STP's) are conducted to verify the performance of equipment under actual operating conditions.

CPS/USAR CHAPTER 01 1.8-7 REV. 11, JANUARY 2005 Regulatory Guide 1.8, Proposed Rev. 2 (February 1979) (Cont'd) Minimum Qualification Level I II III Approve, checkout and initial operation test procedures (C&IO) X Approve acceptance test procedures (ATP's) X Approve preoperational test procedures (PTP's) X Approve startup test procedures (STP's) X

• Direct or supervise conduct of C&IO tests X

• Direct or supervise conduct of ATP's X *Direct or supervise conduct of PTP's X *Direct or supervise conduct of STP's X Evaluate test results of C&IO tests prerequisite to ATP X Evaluate test results of ATP's X Evaluate test results of PTP's X Evaluate test results of STP's X Supervision of test program X Certification of personnel X Evaluate test results of C&IO test prerequisite to PTP's X The process by which individuals are evaluated and certified to their appropriate qualification level, is as follows: a. The person being certified completes a reading list consisting of quality and work related documents as specified in the CPS Startup Manual. b. A resume or equivalent background information concerning education and experience is gathered. c. Prior to certification, the candidate performs work under the direction of certified personnel. The candidate's work qualities are documented and evaluated by the

Level III. d. A Level III will interview the candidate, discussing selected items from the reading list, past work experience applicabibilities to the present job, and considers the candidate's performance to item c above. The specified Level III will consider the individual for certification to one of three qualification levels.

• When an inspection or test requires implementation by a team or group, personnel not meeting the minimum qualification may be used for data taking assignments or equipment operation provided they are supervised by a qualified individual.

CPS/USAR CHAPTER 01 1.8-8 REV. 11, JANUARY 2005 Regulatory Guide 1.8, Proposed Rev. 2 (February 1979) (Cont'd) Delineated below are the requirements used when assigning a level of capability to an individual. The specified requirements are not to be treated as absolute. Other factors such as past performance or proficiency testing may be used to provide assurance that a person can competently perform an assigned task. When these requirements are waived, the basis for the waiver will be documented.

Level I High school graduate, plus one year of commensurate experience in construction, preoperational, startup or operational testing activities.

Level II (a) Graduate of four year accredited engineering or science college or university, plus two years of commensurate experience in construction, preoperational, startup, and/or operational testing activities. At least one year should be associated with nuclear facilities or if not, the individual should have training sufficient to acquaint him thoroughly with the safety aspects of a nuclear power plant. (b) High school graduate, plus four years of commensurate experience in construction, preoperational, startup, and/or operational testing activities in fossil or nuclear power plants, heavy industrial, or other similar equipment or facilities.

At least one year should be associated with nuclear facilities or if not, the individual should have training sufficient to acquaint him thoroughly with the safety aspects of a nuclear power plant.

Level III (a) Graduate of a four year accredited engineering or science college or university plus five years of experience in construction, startup, and/or operational testing activities. At least two years of this experience should be associated with preoperational and/or startup testing in nuclear facilities; or if not, the individual should have training sufficient to acquaint him thoroughly with the safety aspects of a nuclear power plant. (b) High school graduate, plus ten years of experience in testing, maintenance, or operational activities in nuclear or fossil power plants, heavy industrial, or other similar equipment or facilities. Five years of this experience should be associated with construction, preoperational, startup or operational testing and at least two of the five should be in nuclear facilities; or if not, the individual should have training sufficient to acquaint him thoroughly with the safety aspects of a nuclear power plant.

NOTE The word commensurate as used in the description of Level I and II is defined as: The knowledge and skills acquired through past experience corresponds in the same relative proportions to the knowledge and skill requirements of the tasks to CPS/USAR CHAPTER 01 1.8-9 REV. 11, JANUARY 2005 Regulatory Guide 1.8, Proposed Rev. 2 (February 1979) (Cont'd) be assigned to that test engineer. In other words, a person who had two years experience doing only electrical testing activities would not be assigned tasks of a mechanical or fluid nature. However, an engineer with two years experience would have gathered sufficient knowledge and skills to be assigned to an HVAC system startup. HVAC balancing would require additional experience. 2.

Reference:

Paragraph C.3.c - Clarification is provided concerning the qualifications of reviewers of preoperational and startup test procedures. The qualifications of reviewers and approvers is differentiated. The A/E or a consultant may be utilized to review portions of procedures. Furthermore, CPS staff personnel, who do not possess overall qualifications, may be utilized to review specific procedures if they are qualified in the particular area covered by the procedure. 3.

Reference:

Paragraph C.8 - Exception is taken to the requirement that non-licensed operators must have one year of power plant experience, 6 months of which must be at the assigned facility. This requirement would require the facility to carry at least one additional employee in an "in training" status since the auxiliary operator position is intended to be an entry level job. It is also believed that flexibility is lost when job vacancies are created. It is believed that there are numerous power plant duties having no safety significance that can be performed by an operator in an entry level position. This individual can receive on-the-job and formal training while contributing to plant productivity. 4.

Reference:

ANSI/ANS-3.1-1978, Paragraph 4.6.1 - The engineer in charge of technical support may not possess all specified qualifications. However, adequately qualified personnel will be available in the company engineering staff or through consultants to assist the engineer in charge. 5.

Reference:

ANSI/ANS-3.1-1978, Paragraph 4.7 - Independent review is provided by the Nuclear Safety Review Board (NSRB). The NSRB is a standing committee. Since the NSRB is a standing committee, paragraph 4.7.1 is not applicable to its members. 6.

Reference:

ANSI/ANS-3.1-1978, Paragraph 4.7 Exception is taken to the qualification requirements for the staff specialists for the review committee. The review committee is required to contain personnel with expertise in all of the appropriate areas. When such expertise is not available on the review committee unit, the expertise will be available in the company or from outside consultants. 7.

Reference:

ANSI/ANS-3.1-1978, Section 5.2 and Section 5.5 - Exception is taken to Section 5.2 "Training of Personnel to be Licensed by the NRC" and Section 5.5 "Operator Retraining and Replacement Training." The Clinton Power Station Licensed Operator Initial and Continuing Training Programs are accredited by the Institute of Nuclear Power Operations (INPO) National Academy for Nuclear Training. These programs are based on a systems approach to training (SAT) and are accredited by the National Nuclear CPS/USAR CHAPTER 01 1.8-10 REV. 11, JANUARY 2005 Regulatory Guide 1.8, Proposed Rev. 2 (February 1979) (Cont'd) Accrediting Board. These programs shall meet the requirements of 10CFR55, "Operators' Licenses." 8.

Reference:

ANSI/ANS-3.1-1978, Section 4, "Qualifications," Paragraph 4.2.2, "Operations Manager' - Exception is taken to the requirement "the Operations Manager shall hold a Senior Reactor Operator's License." The CPS Technical Specifications require "The Operations Manager or at least one Operations Middle Manager shall hold an SRO license for Clinton Power Station." This is consistent with ANSI/ANS-3.1-1978. USAR Subsection: 12.5.1, 13.1.3.1, 13.2.1, 13.2.1.1, 14.2.1.5, 14.2.2.5, TS 5.3.1, and ORM 6.4.1.

CPS/USAR CHAPTER 01 1.8-11 REV. 11, JANUARY 2005 Regulatory Guide 1.9, Rev. 2 (December 1979), and Rev. 3 Selection, Design and Qualification of Diesel-Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants Project Position - The project complies with NRC Regulatory Guide 1.9, Rev. 2 (December 1979), and with selected portions of Rev. 3, as described below: (1)

Reference:

Paragraphs C.1 and C.2 - Based upon updated diesel generator loading calculations, the loading on the diesel generators could be higher than the continuous rating of the diesel generator. Paragraph C.1 states that at the construction permit stage of design, the sum of the estimated loads needed at any one time is to be less than the continuous rating of the diesel generator. Paragraph C.2 also specifies that during the operating license stage of review, when a more accurate estimate of the safety loads is possible, a somewhat less conservative approach is permitted. Based on this, CPS uses the 2000-hour rating for illustrating the ability of the diesel to handle the maximum coincident loading expected following an accident. (2)

Reference:

Paragraph C.7 of Rev. 2 (December 1979)- Isolation valves are not included on instrument sensing lines, so that calibration of instrument sensors cannot be accomplished without disconnecting the sensor from the

sensed variable. (3)

Reference:

Section C, Paragraphs 2.2.2, 2.2.8, 2.2.9, and 2.2.10 of Reg. Guide 1.9, Rev. 3, establish the diesel-generator acceptance criteria and loading requirements for the load-run test, the full-load rejection test, the endurance and margin test, and the hot restart test. (The above referenced paragraphs of Reg. Guide 1.9, Rev. 3, were approved for use at CPS via Operating License Amendment 118.) (4)

Reference:

The General Electric HPCS system power supply unit Licensing Topical Report, NEDO 10905, gives the starting and accelerating charactersitics of the diesel-generator set with the various loads in the proper sequence. Although the voltage and frequency characteristics do not meet NRC Regulatory Guide 1.9, justification for this is given because of the unique requirements of the system. The HPCS diesel generator is unique in that its load is composed predominantly of one large motor whose horse power is approximately the same as the diesel-engine.

Mechanical (Cadweld) Splices in Reinforcing Bars of Category I Concrete Structures Project Position - The Project complies with NRC Regulatory Guide 1.10 with the following exceptions: (1)

Reference:

Paragraph C.1 - Each operator prepared two qualification splices for each of the positions (e.g., vertical, horizontal, diagonal) using the largest bar size for that position. (2)

Reference:

Paragraph C.1 - Operator requalification was necessary if (1) the specified splice position has not been used for a period of three months or more, (2) completed splices consistently failed to pass visual inspection or tensile test requirements, or (3) reason existed to question operator's ability. (3)

Reference:

Paragraph C.3.a - Testing complied with ASTM A370-75.

(4)

Reference:

Paragraph C.3 - Rebar detail drawings are prepared showing the location of all reinforcing bar lapped splices or cadwelds. If during construction the location of the splices or cadwelds differs from the location shown on the detail drawing by more than the specification tolerances, a Field Change Request (FCR) or Non-Conformance Report (NCR) is issued by the Constructor. When approval of the FCR or NCR is obtained, the number of the FCR or NCR is

posted against the drawing and becomes part of the permanent plant records. (5)

Reference:

Paragraph C.5.a - Procedure for Substandard Tensile Test Results were as follows: a. If any production or sister splice used for testing fails to meet the strength requirements (125% of minimum yield strength specified in ASTM A615-75) and failure occurs in the bar, the failure shall be reported to the Consulting Engineers. b. If any production splice used for testing fails to meet the strength requirements (125% of minimum yield strength specified in ASTM A615-

75) and failure did not occur in the bar, the adjacent production splices on each side of the failed splice shall be tested. If any sister splice used for testing fails to meet the strength requirements and failure did not occur in the bar, two additional sister splices shall be tested. If either of these retests fail to meet the strength requirements, splicing shall be halted.

Splicing shall not be resumed until the cause of failures has been corrected and resolved by the Contractor to the satisfaction of the Consulting Engineer. USAR Reference - Appendix B CPS/USAR CHAPTER 01 1.8-13 REV. 11, JANUARY 2005 Regulatory Guide 1.11, Rev. 0 (March, 1971)

Instrument Lines Penetrating Primary Reactor Containment Project Position - Comply with the following exception:

Reference:

Paragraph C.1.c(2) - Self-actuating Excess Flow Check Valves (EFCV's) that are installed in low pressure instrument sensing lines (i.e., lines that sense, drywell pressure, containment pressure, suppression pool level, and ventilation system pressure) are not designed to close if the instrument line integrity outside containment is lost during normal reactor operation. During normal reactor operation, there exists a small difference in atmospheric pressure between the drywell or containment buildings and the secondary containment, the building where all EFCV's are located. If an instrument line outside containment ruptures during normal reactor operation, there may be insufficient differential pressure to actuate the EFCV. However, since there is negligible radiological source term available for release from inside the drywell or containment during normal reactor operation, the safety consequence of a low pressure instrument sensing line failure is considered to be insignificant. The offsite radiological exposure from a single failure of an EFCV will remain substantially below the guidelines of 10CFR100 and the integrity and functional performance of the secondary containment and its associated standby gas

treatment system (SGTS) will be maintained. USAR Subsections - 6.2.4, 6.2.6.3, Table 6.2-47, 7.1.2.6.3, 7.3.2.2.2.1.1, 7.4.2.1.2.1.2 Regulatory Guide 1.12, Rev. 1 (April 1974)

Reactor Coolant Pressure Boundary Leakage Detection Systems Project Position - The requirements of the NRC Regulatory Guide 1.45 are met with the following exceptions for those portions of the station under the balance of plant systems scope of design: 1.

Reference:

Paragraph C.5 - The sensitivity and response time of airborne particulate and gaseous radioactivity monitors is not adequate to detect a leakage rate of 1 GPM in less than one hour. The correlation between flow rate and radioactivity is not valid due to various complex factors discussed in Section 5.2.5.2.2. The monitor will not always alarm for 1 GPM in one hour and, therefore, is considered as qualitative indication of the presence of abnormal leakage. Similarly, because the drywell floor drain sump flow monitoring system calculates the unidentified leakage rate based on drywell floor drain sump pump discharge flow, this system is not sensitive enough to detect a leakage rate of 1 GPM in less than one hour over the entire range of potential leakages. This

system is, however, capable of promptly detecting leakage rates and leakage rate increases prior to exceeding Technical Specification operating limits. CPS will follow the guidelines of ANSI/ISA S67.03, Standard for Light Water Reactor Coolant Pressure Boundary Leak Detection, October 3, 1982. 2.

N-237 - Hydrostatic Testing of Internal Piping, Section III, Division 1. Exemption from hydrostatic testing of the portion of ASME Class 2 containment spray piping system extending downstream from the containment penetration to the containment spray device Reference is made to NRC's letter Docket Nos. 50-461/462 dated August 18, 1980, with expressed comment that this code case requires the examination of the exempted piping in accordance with NB 5200 even though the piping is ASME Class 2. b. N-241 - Hydrostatic Testing of Piping, Section III, Division 1. Exemption from hydrostatic testing of safety relief valve discharge piping from the main steam, HPCS, LPCS, RHR, and RCIC systems to the suppression pool; including the submerged portions and terminations.

Reference is made to NRC's letter Docket Nos. 50-461/462 dated August 18, 1980, which clarified the code case applicability only to the submerged portions of the above-cited systems. c. N-240 - Hydrostatic Testing of Open Ended Piping, Section III, Division 1. Exemption from hydrostatic testing of:

(1) Shutdown service water discharge to the ultimate heat sink beyond the last isolation valve. (2) Various diffusers, drains, and return piping to the several fuel pools in the containment and fuel buildings. (3) Suppression pool makeup system piping connecting upper containment pool with suppression pool. (4) Diesel oil system pump suction piping from and return piping to the diesel generator fuel oil storage tanks and the fuel oil day

(7) HPCS, LPCS, RHR, RCIC, and suppression pool cleanup pump suction piping from suppression pool to first isolation valve outside containment and return lines to the suppression pool. The approval to use Code Case N-240, "Hydrostatic Testing of Open Ended Piping, Section III, Division 1," was aut horized by NRC for construction of above cited components with no limitations by letter Docket Nos. 50-461/462 dated

February 25, 1980. d. N-341 - Certification of Level III NDE Examiner Section III, Divisions 1 and 2. The approval to use Code Case N-341 without limitations was granted by NRC letter Docket No. 50-461 dated April 11, 1983. e. N-315 - Repair of Bellows, Section III, Division 1.

Repair of bellows under ASME Section III, Division 1 for ten guard pipe expansion bellows at CPS. The approval for use of Code Case N-315 was authorized by NRC letter Docket No. 50-461 dated September 27, 1983 with the condition that CPS submit the description of the repair as well as justification for

repairing the bellows rather than replacing them. Following receipt of NRC's

approval for the repair, but prior to making the repair, CPS is to provide NRC the results of the qualification on the full-scale facsimile bellows, including the design requirements to assure that the repai r meets the requirements of the design specification. 2. Illinois Power Company requested and received approval for application of the following code cases: a. N-356 - Certification Period for Level III NDE Personnel Section XI, Divisions 1, 2, and 3.

The approval to use Code Case N-356 was authorized by NRC letter Docket No. 50-461 dated April 11, 1983 with no limitations. b. N-397 - Alternate Rules to the Spectral Broadening Procedures of N-1226.3 for Classes 1, 2, and 3, Section III, Division 1.

The approval to use Code Case N-397 was authorized by NRC letter Docket No. 50-461 dated April 5, 1985 with no additional requirements other than those specified in the code case. c. N-411 - Alternate Damping Values for Seismic Analysis of Piping Section III, Division 1, Class 1, 2 and 3 Construction. The approval of Code Case N-411 was conditionally granted by NRC letters dated July 19, 1985 and April 5, 1985. This code case will be used CPS/USAR Regulatory Guide 1.84 (Cont'd) CHAPTER 01 1.8-44 REV. 11, JANUARY 2005 for piping systems analyzed by response spectrum methods and not those using time-history analysis methods. This code case will be used, as necessary, for any future piping and equipment dynamic analysis or reanalysis. If, as a result of using the damping value in ASME Code Case N-411, piping supports are moved, modified or eliminated, any increased piping displacements due to the greater piping flexibility will be checked to assure that they can be accommodated and that there will be no adverse interaction with adjacent structures, components, or equipment. When the alternative damping values of this code case are used, they will be used in their entirety in a given analysis and not a mixture of Regulatory Guide 1.61 and Code Case N-411. This code case will be applied for both hydrodynamic loads as well as seismic loads; however, the damping values in Code Case N-411 are limited to a response frequency below 33 Hz. d. N-413 - Minimum Size of Fillet Welds for Linear Type Supports, Section III, Division 1, Subsection NF.

The approval to use Code Case N-413 was authorized by NRC letter Docket No. 50-461 dated April 30, 1985 with no limitations other than those stated in the text of the code case. 3. Acceptable code cases annulled by action of the ASME Council (or deleted in later revisions to this guide), but specified for procurement or other activities, shall remain valid. Commitment to meet a specific revision of this guide has little significance since the guide is revised as new code cases are issued by the ASME and approved by the NRC.

'k is used for computing the damped frequency '

k of a system or a subsystem with closely spaced modes, while an uncorrected damping factor k is used per the regulatory guide. The justification for using

'k instead of k in the calculation of '

k is presented in the attached "Supplement to the Position on Regulatory Guide 1.92". USAR Section/Subsection - 3.7.2.7, 3.7.2.12, 3.7.3.7, 3.7.3.8 CPS/USAR CHAPTER 01 1.8-47 REV. 11, JANUARY 2005 Supplement to Position on Regulatory Guide 1.92 In the double sum method of modal combination, a modified damping factor, instead of an uncorrected value as in Equation (10) of Regulatory Guide 1.92, should be used for

the damped frequency to evaluate the correlation coefficient of the closely space modes. Equations (8), (9), (10) and (11) of the regulatory guide are based on a study by Rosenblueth and Elorduy (Reference 1) Referring to that paper, for a single-degree-of-freedom system governed by the equation of motion, ()()()()t x t q t q 2 t q 2 1 1 1=++ (1) The correction factor for damping can be expressed as (Equation (4) of Reference 1) 2/1 1 1)2/1 ()()(s Q Q+= (2) where s is the duration of a segment white noise excitation. E(Q) and E(Q

0) are the expected value of the dam ped and the undamped systems. The maximum response of a system to a transient disturbance of form x(t) = f(t) W(t) can be expressed (Equation (8) of Reference 1) dt q Q 2 0 2µ (3) The transfer function q(t) for the deformation of the system expressed by Equation (1) is (Equation 10.3 of Reference 2) y q(t)t'1sin t)11(exp'11= (4) where 2 1 1 1 1'= (5) When q is the pseudo-velocity of a single-degree system, the second member in Equation 4 gives 1/2 1 1. In order to adjust the percentage of damping to coincide with the expected response, Rosenblueth suggested the use of a modified damping factor (Equation (9) of Reference

1) s/2'1 1 1+= (6) in the system's natural mode of vibration.

CPS/USAR Supplement to Position on Regulatory Guide 1.92 (Cont'd) CHAPTER 01 1.8-48 REV. 11, JANUARY 2005 In other words, the uncoupled equation of motion of a multi-degree-of-freedom system should be adjusted as

)t (x a)t (q)t (q'2)t (q i i 2 i i i i i=++ (7) and the transfer function is given by (Equation 10.3 of Reference 2) t'sin)t'(exp'a i)t (q i i i i i= (8) where 2 i i i'1'= (9) Note here the modified damping factor

'i and not the uncorrected damping value i is used in Equation (9) for the damped frequency of the adjusted system. The final solution is then obtained based on the transfer function of Equation (8) but not Equation (4), as

)1 (/Q Q j i Q i Q 2 ij j i 2 i 2++= (10) where )/(j j i i j i ij+= (11) 2 i i i'1'= (12) Thus, a modified damping factor for the damped frequency should be used. Amin and Gungor (Reference 3) and Singh, Chu and Singh (Reference 4) also used the modified damping factor for the damped frequency in their computation of the correlation coefficent of closely spaced modes. For a lightly damped system and an earthquake duration of 10 seconds as in the Clinton design basis, the damped frequency based on a modified damping factor and the damped frequency based on a uncorrected damping factor are approximately the same.

However, on a theoretical basis, the modified damping factor should be used for the damped frequency in the evaluation of the correlation of the closely spaced mode response. For a 10 Hz system with 2% damping and 10 seconds earthquake duration, the damped frequency using modified and uncorrected damping factors is 9.9973 Hz and 9.9980 Hz respectively. Thus the use of either modified or uncorrected damping factor does not affect the results.

An Acceptable Model and Related Statistical Methods for the Analysis of Fuel Densification Project Position - GE meets the requirements of this regulatory guide with the exception of the method of derivation of the densification values for resintering tests.

GE believes that the NRC method in the regulatory guide represents a significant departure from previously approved GE methods. Specifically, this departure requires an increase in the level of statistical confidence level from 50 percent to 95 percent employed to infer population parameters from the sampling results. This departure from the GE approach previously approved by the Staff is interpreted as the introduction of additional conservatism in the GE densification analyses, and such a Staff position is considered inappropriate in recognition of the GE/NRC agreed upon conservatisms incorporated into the individual densification models during their

formulation. USAR Section - 4.2 CPS/USAR CHAPTER 01 1.8-59 REV. 11, JANUARY 2005 Regulatory Guide 1.127, Rev. 1 (March 1978)

Site Investigations for Foundation of Nuclear Power Plants Project Position - Most of the geotechnical site investigation work for Clinton Power Station was done prior to the original issuance of Reg. Guide 1.132 in September, 1977, therefore compliance was not possible. However, the work done complies with Reg.

Guide 1.132 with the following exceptions: (1)

Reference:

Paragraph C.2 - The coordinates for the borings are not shown on the boring logs. However, drawings showing the locations of these borings are

provided and have the state plane coordi nate system identified on them. (2)

Reference:

Paragraph C.3 - Piezometers were not used to monitor the effects of dewatering for the main plant excavation. The principle reasons for not establishing a monitoring system were: 1. The surrounding tills were impermeable and very little seepage was expected and obtained. 2. The major dewatering problem would be the removal of rain water.

3. There were no ground water users in the area of the excavation that would be affected. (3)

Reference:

Paragraph C.5 - The boring programs for the Main Plant complex, the Emergency Core Cooling System (ECCS) pipeline, the Ultimate Heat Sink, and the Main Dam do not fully comply with the requirements as provided in Appendix C of this regulatory guide. However, the borings for the Main Plant Ultimate Heat Sink, and Main Dam were located and drilled to provide an adequate geologic cross-section of the respective areas. It was also felt that the borings located near the Main Plant provided an adequate description of the subsurface materials to be encountered along the ECCS pipeline. Therefore, additional borings along the pipeline route were not drilled. (4)

Reference:

Paragraph C.6 - Continuous sampling of the soils encountered in the borings was performed in a few borings, but not to the extent required by this regulatory guide.

margin. (3)

Reference:

ANSI N195-1976 Section 6.3 and Appendix A - A duplex strainer is not provided in the transfer pump suction line to preclude a postulated loss of pump suction by strainer plugging. A Y-type strainer is provided in a recirculation line. The tank outlet nozzle is six inches above the bottom of the tank to prevent sludge from entering the line. (4)

Reference:

ANSI N195-1976 Section 7.5 Paragraph 1 - A non-nuclear safety related strainer is provided in each fill line. There is a locked closed valve between the strainer and the storage tank to preclude entry of deleterious material. (5)

Reference:

ANSI N195-1976 Section 8, Paragraph 1d - A high level alarm is not provided for the supply tanks. A high level alarm for the storage tank could be useful only when filling the tank. Since there are level indications which will be monitored during the filling, a high level alarm would not enhance the safety of the system. (6) The fuel oil will be sampled and analyzed periodically to verify that its quality meets the diesel manufacturer's recommendations, the requirements of ASTM-D975-06b and the CPS Technical Specifications. The methods and tests specified in ASTM-D975 will be followed when there are differences between ASTM-D975 and the diesel manufacturer's recommendations. However, all the diesel manufacturer's recommended limits will be met when they are relevant to the test methods specified in ASTM-D975. (7)

Reference:

Paragraph C.1.g The Diesel Fuel Oil fill lines have a protective coating and an impressed type cathodic protection system, although the cathodic protection system may not meet the requirements of NACE Standard RP-01-69.

This is adequate because the fill lines are not required for proper operation of the diesel generator units during post-LOCA maximum load demands. All other equipment in the Diesel Generator Fuel-Oil Storage and Transfer System do meet NACE Standard RP-01-69 requirements.

Guidance for Residual Heat Removal The Clinton plant is designed so that the RHR system complies with the intent of this guide except as follows: 1. Regulatory Position C.2.a, second sentence suggests alarms which the RHR system does not have. 2. Regulatory Position C.2.a, third and fifth sentences suggest independent and diverse interlocks. The RHR interlocks are not diverse. 3. Regulatory Position C.2.a, fourth sentence suggests that failure of a power supply should not cause any valve to change position. Failure of the Reactor Protection System instrument power bus in one division will cause automatic isolation of the RHR shutdown suct ion valve in that division. The Clinton design complies with Regulatory Guide 1.139, by using the following alternate approaches to Regulatory Guide 1.139 position C-2a and C-5. 1. Position C.2.a, second sentence - The design provides for valve position indication in the control room. The addition of alarms to alert the operator that an RHR valve is open is not considered necessary because of the number of procedural and administrative controls that must be exercised in taking the reactor from a power mode to the RHR mode and because the reactor high pressure signals are permissively interlocked into the valve opening logic to disallow valve opening on reactor high pressure. 2. Position C.2.a, third and fifth sentences - The design complies with these suggestions by the use of independent interlocks and series valves powered by redundant power sources. 3. Position C.2.a, fourth sentence - The design complies with the intent of the Regulatory Guide (i.e., protect the low pressure piping). Upon failure of logic the RPS power supply, valves are signaled to close. However, division power would need to be available to implement the change in valve position to the close position.

Containment Isolation Provisions for Fluid Systems Project Position - Comply with the following clarification: 1. Reference ANSI N271-1976 Paragraph 4.2.3 - A short circuit in the valve indication circuit would cause the fuse at the motor control center to open, thus rendering the valve electrically inoperable. This is an acceptable condition since only a single failure in one Electrical Division need be considered. Inboard and outboard isolation valves have different Divisional assignments so that containment isolation can be accomplished even considering the loss of one of the two valves. 2. Reference Regulatory Guide Position C.2 - Valve Numbers lE12-F008, 1CC071, 1CC072, ICC073, 1CC074, 1CY020, 1CY021, 1FP051, 1FP054, 1FP078 and 1FP079 will have power removed by locking the circuit breaker in the open position. During the time that power is removed from the valve it will be considered as a manual valve and will not have position indication in the Main Control Room. During times that power is applied and the valve is required to be open, valve position indication will be provided. USAR Section - 6.2.6, TS3.6.1.3 CPS/USAR CHAPTER 01 1.8-68 REV. 11, JANUARY 2005 Regulatory Guide 1.142, Rev. 0 (April, 1978)

Safety Related Concrete Structures for Nuclear Power Plants (Other than Reactor Vessels and Containments)

Project Position - Comply with the following clarifications: 1. R.G. 1.142 generally endorses ACI 349-76. However, the Regulatory Guide does not endorse the provisions of ACI 349-76 as adequate for drywell structures. CPS design utilizes the provisions of Sections 10.6.3 of ACI 349-80 in place of the 1976 version of the standard. 2. In some cases, CPS utilized the bend test requirements of ASTM A615 in place of ACI 349. Additional detail on this clarification is provided in USAR Section 3.8.3.2.2. USAR Subsections - 3.8.3, 3.8.4, 3.8.5.

Reference:

Section B, Page 2, First Paragraph, First Sentence - It is clarified that the radwaste systems for CPS are considered to begin with and include the interface valves. 2.

Reference:

Section B, Page 2, First Paragraph, Second Sentence - It is clarified that the radwaste system for CPS terminates at the end of the pipe containing the last isolation valve before the point of controlled discharge to the service water discharge line, or at the end of the pipe containing the last isolation valve before the cycle condensate storage tank, or at the point of storage of packaged solid waste prior to shipment offsite to licensed burial ground. 3.

Reference:

Paragraphs C.1.1.2, C.2.1.2, C.3.1.2 Materials for pressure-retaining components conform to the requirements of ASTM Specifications. 4.

Reference:

Paragraph 4.3 - It is clarified that the scope of radwaste system pressure testing includes all pressure-retaining components, appurtenances, and completed systems. Bolts, studs, washers, gaskets, and possible localized instances of pump and valve packing are exempted from the pressure test. This is consistent with ASME Section III NB6000 and ANSI B31.1 (1983 edition). The

Off-Gas System will be pneumatically tested at a minimum of 75 psig for no less than 30 minutes.

CPS/USAR CHAPTER 01 1.8-69 REV. 11, JANUARY 2005 Portions of the radioactive waste management system contain polypropylene lined steel pipe and valves. These pipes and valves are in the demineralizer subsystem because of the superior corrosion resistance of polypropylene to chemicals. This portion of the subsystem will only be inservice leak tested at normal operating pressure. 5. Non-Category 1 equipment is evaluated per DC-ME-17-CP, Revision 1.

6. Plastic spacers are used on an as needed basis at flanged joints of plastic lined pipe. The spacers are provided by the manufacturer of the lined piping to adjust for small fit-up differences. 7.

Reference:

Paragraph C.1.2.1 - There are no local alarms to alert people in the area of potential overflow conditions. In lieu of this, the operator annunciator response procedure in the Radwaste Operations Center (ROC) has a required

action to make a plant wide announcement regarding the potential overflow and alerting individuals in the area of potentially changing radiological conditions. 8.

Reference:

C.3.1 - Materials for non-pressure retaining attachments and appurtenances to solid waste tanks are not required to be constructed of materials conforming to the requirements of Section II of the ASME Boiler and Pressure Vessel Code. Examples of this type of equipment are nozzles, piping and welds in atmospheric tanks which do not carry process fluid and whose elevation is above the tank overflow level. In addition, these non-pressure retaining attachments and appurtenances are exempted from the design, construction and testing criteria set forth in this section, section C.4 and Table 1 to this regulatory guide. Failure of these components would not result in a radioactive release. USAR Sections - 11.2.1, 11.3.2.2.1, 11.4.2, 11.5.1.1.2
