Insure the tendon testing program engineer is in agreement with plans to install the test rigs pre outage. Address placing the equipment (or not) over the BWST Reviewed plan with Rick Portmann. The work platforms are designed for seismic and hurricane loads while stationary and when moving on the rail system and therefore pose no danger to the BWST.

Additionally, the BWST tank is almost 25' away from the outside edge of Buttress #4, so even if the platform fell it cannot hit the top of the tank. The sodium hydroxide storage tanks, just north of the BWST are enclosed by 2'-2" thick reinforced concrete wall and roof enclosure that is a Class I structure, therefore missile protected.

Where does the grease go from the tendons being cut?

How is the water handled that goes down the tendon sleeves into the tendon gallery?

Refer to Item #3 and #5 above.

Waste grease is managed by PSC in accordance with the "Waste Vendor Program" corporate policy (EVC-SUBS-00107). PSC has contracted Heritage Disposal to collect the grease and to dispose of it by burning. Heritage is in the process of becoming an approved PE vendor. All documentation generated as part of the disposal, e.g., manifests, disposal certificates, etc, will be provided to the CR3 waste coordinator (Brian Wood, currently).

10 B.6.6 Environmental Conditions: What is the water treatment performed by the water treatment skid provided by Mac and Mac? Can the treated water be sampled?

Is there a volume integrator that tracks the total water volume being treated?

The portable waste water treatment facility consists of three 20,000 gallon tanks that can treat up to 360 gallons of water per minute. These tanks will be sampled by RP for radioactive material prior to their use to establish that they are H03 Reviews Page 12 of 31

PCHG-DESG Engineering Change 0000063016RO clean. Treatment basically consists of a four step process of settling, flocculation, pH measurement and adjustment, and the capture of grease (if present) in grease traps before discharge. Grease and oil will be captured in Tank #3 thru absorbent booms. Disposal of the grease is PSCs responsibility.

Water in each of the tanks can be sampled.

11 B.6.12 Chemistry Requirements: Ist paragraph top ofpage 60, reword sentence "Samples for radiological testing and analysis will be... tested at the on-site Chemistry", not RP, "laboratory".

With regard to the sentence "Discharge of water and rubble may continue uninterrupted while samples are being tested and analyzed", it should be noted that the release of the first batch from the last tank will be not be permitted until it has been sampled and analyzed to ensure that it is OK to release. R. Pinner would like to see the "Containment Opening RP Task Plan" referenced in this section.

Who in the Environmental Group has confirmed that discharging the hydrodemolition waste water after treatment by Mac and Mac is allowed by the Industrial Waste Water Permit?

RP Laboratory changed to Chemistry Laboratory.

How will the tendon grease be captured, stored and disposed? We need to ensure all grease in tendon gallery does not go to floor drains.

Tendon grease is captured in 55 gallon drums. The grease has a high viscosity and will not flow if spilled. Plastic sheeting will be taped to the tendons gallery floor and side walls (installation instructions have been revised - Section D.2.1.1 - to include adding plastic sheeting in the gallery). Waste grease is managed by PSC in accordance with the "Waste Vendor Program" corporate policy (EVC-SUBS-00107). PSC has contracted Heritage Disposal to collect the grease and to dispose of it by burning. Heritage is in the process of becoming an approved PE vendor.

All documentation generated as part of the disposal, e.g., manifests, disposal certificates, etc, will be provided to the CR3 waste coordinator (Brian Wood, currently).PSC manages waste grease disposal The floor drains in the tendon gallery must be blocked. Water draining from the tendon sheaths will drain to the tendon gallery sump from where it will be pumped by Bechtel out of the tendon gallery to Mac and Macs water treatment plant before discharge to the settlement ponds. Sump pumps SDP-3A and SDP-3B must be turned off/disabled immediately prior to the start of hydrodemolition. According to PSC, the primary purpose of the 55 gallon drums placed in the gallery is to collect any large concrete fragments and dissolved solids.

Concrete wall debris should be non-contaminated but must be collected in such a manner to not allow debris pieces to be strewn on the berm.

Concrete will be analyzed prior to release from RCA.

A safety net will be erected to contain any debris resulting from hydrodemolition activities (Refer to installation activities Section D.2.1.3). Refer to Section B.6.6 and B.6.12 an evaluation of the requirements for testing the concrete debris and waste water.

How will the project ensure operations does not vent in containment during the liner breach? If a vent were to occur, the release needs to be contained (system piped).

Breaching of the RB liner should be handled in. a manner similar to other large RB breaches (i.e. Personnel and Equipment Hatch opened).

The CR-3 Offsite Dose Calculation Manual (ODCM) currently contains the plants radioactive effluent controls and radiological monitoring program and specifically ODCM Representative Sampling Method No.

3.1-5 already addresses radiological controls when large openings to outside atmosphere are created in the Reactor Building. The ODCM list requirements such as:

The. Reactor Building purge exhaust fans are operational The Reactor Building supply fans are shut down If the purge exhaust must be shut down then either the personnel hatch or equipment hatch openings must be closed

• Monitor the Reactor Building recirculation system by using RM-A6 or by taking general area air samples.

Other considerations to be considered when the liner is breached are:

" Run the main purge long enough to assure cleanup of the RB atmosphere Degas and depressurize the Reactor Coolant System.

A precaution has been added in the installation instructions (Section D.2.1.3) that Operations must be aware that any venting of radioactive material in the RB must with the containment breached must be handled in accordance with the CR3 Offsite Dose Calculation Manual (ODCM).

will have most of the area between the MSB and OSB (to be removed) posted as a RCA. Currently, Station HP does not see this as a time restraint for releasing the large equipment planned in this area. The equipment will be evaluated and surveyed as necessary.

I 10 Until concrete analysis indicates concrete is free of radioactivity, control of equipment and water is necessary. Water must be collected and analyzed prior to its release.

Further discussions are necessary between NPC and the Station HP to talk about sampling methodology, location of tank(s) and release of water. Chemistry plans to sample water prior to release to settling ponds for radioactivity and NPDES parameters and will periodically sample thereafter. What is to be done with the concrete slurry/sludge?

Radiation protection will be responsible for radiological testing of the rubble. Samples for radiological testing and analysis will be taken at the collection bins and tested at the on-site RP laboratory. Discharge of the water and rubble may continue uninterrupted while samples are being tested and analyzed. Refer to the Containment Opening RP Task Plan for specific details on handling and testing of the waste generated during hydrodemolition.

The large concrete fragments and fine particles that accumulate in the collection tanks are periodically sucked out by a vacuum truck and hauled off-site to a landfill or may be used for beneficial on-site construction purposes, such as road building or for drainage ditches.

Only pH sampling will need to be performed as a pre-requisite for discharge. Contractor should strive to keep the pH between 6.0 and 9.0. Periodic sampling of pH will be needed.

A "stop job" limit will be established at pH less than or equal to 2, or pH greater than or equal to 12.5.

Carolyn Johnson Multi-Discipline 5/19/08M Ite Comn Resolution 1

The Environmental Specialist for NPC is Ron Johnson. We have both discussed this project with Corporate EHSS and Ron will be taking the lead so all questions should be addressed to him. If he has questions concerning the plant, he will contact Carolyn Johnson, the CR3 Plant Environmental Specialist.

However, pH, TSS, oil/grease need to be performed due to operational and sludge concerns in the pond. Oil/grease are major concerns due to the tendons-must keep this out of the water. pH must be measured to ensure this is not hazardous waste. TSS is a concerns for equipment.

Per agreement between Carolyn Johnson, Ron Johnson and Corporate EHSS specialist (Doug Yowell) the following testing is required:

Only pH sampling will need to be performed as a pre-requisite for discharge.

Contractor should strive to keep the pH between 6.0 and 9.0. Periodic sampling of pH will be needed. A "stop job" limit will be established at pH less than or equal to 2, or pH greater than or equal to 12.5.

Recommend that laboratory samples for pH, TSS, and Oil & Grease be collected at about 3 times during project (start, middle, end), and results placed in project file and plant file. These samples are for documentation only, and would not require batch processing of the wastewater, or delay transfer.

Mac and Macs water treatment plant consists of three 20,000 gallon tanks. Per discussion with Rudy Pinner and Mike Siapno, samples can be taken from the first tank if the tanks are sampled by RP for radioactive material prior to use to establish that they are clean. Grease and oil will be captured in Tank #3 thru absorbent booms.

Sump pumps SDP-3A and SDP-3B must be turned off/disabled immediately prior to the start of hydrodemolition. According to PSC, the primary purpose of the 55 gallon drums placed in the gallery is to collect any large concrete fragments and dissolved solids.

Typically, in other SGRs these drums overflow with water which is collected in the gallerv sump and pumped out.

I Does the EC identify SP affected due to new tendons installed and tensioned. B. 15 SP-182, RB Structural Integrity Tendon Surveillance, has been added to the ADL.

The procedure will be affected due to the new tendons and revised predicted tendon losses.

2 EC should give specific plans for water source, storage and delivery The appropriate work orders will detail the requirements for water delivery, storage and the means of piping it to and from the containment. The containment opening Task Manager is responsible for determining if the settling ponds have adequate storage for the expected 2

million gallons of waste water. ECED 59400 identified the possible source of this water as the well fields located to the east of CR3, operated and maintained by the fossil group at Crystal River South (CRS). Well water would be diverted through existing CRS plant piping or temporary piping to one of the existing abandoned oil storage tanks (Cap.

8,000,000 gallons) which have been successfully used in the past by CRS to satisfy requirements for bulk water storage for other high water demand projects. Water from this storage tank will then be pumped either via temporary piping or existing available plant piping to the hydrodemolition equipment located at the containment access Opening.

The design spec mentioned the substitution of A514 Grade Q for Grade E or SSS-100, and later mentions substituting A615 Grade 60 for Grade 40. Just wanted to ask if a material design reconciliation had been done for these substitutions. Thanks.

Received 5/21/08 from Jim Derrico about the requirements for design reconciliation. Section B.6.8-c contains an explanation about the substitution of ASTM A524 Grade Q material for SSS-100, ASTM A514 Grade E material.

Attachment Z01RO contains an evaluation by Jeff Finnell as to the acceptability of this substitution. Section B.6.8-h contains an evaluation of the acceptability of using Grade 60 material versus Grade 40 material for the concrete reinforcement steel. Jeff Finnell believes that these evaluations are adequate to justify the material substitution and no further reconciliation is required (except at the conclusion of the project when the NIS2s will have to be prepared in accordance with ASTM Section XI).

2 EC discusses the creation of used grease waste, and that the disposal of that waste shall be the responsibility of PSC. 1)

Need a better estimate of the amount of used grease that will be generated. 2)

Need to verify that Brian Wood (CR3 waste coordinator) is in agreement with allowing PSC to handle disposal, and 3)

If PSC is allowed to handle disposal, corporate policy requires that they utilize a Progress Energy approved waste disposal vendor, and that all disposal documentation is provided to Brian Wood for record retention. (If PSC wants to use a vendor not on the approved list, project will need to initiate a request to add that vendor to the approved list in accordance with corporate procedure EVC-SUBS-0107.)

PSC estimates that there will be 150 drums of used grease that will be sent for disposal.

49 (Technical) How are GTSTRUDL error notices reviewed for potential impact to the computer analyses supporting the EC? No documentation found to discuss their impact.

The following explanation is from S&Ls Javad Moslemian (Manager Civil Engr):

We have procured the "GTSTRUDL" program under GTSTRUDL's QA program. Anytime, an error is detected by the GTSTRUDL company, GTSTRUDL notifies us of the error. Once the error notification is received by S&L, it is forwarded to the process owner responsible for the GTSTRUDL program.

The process owner then reviews the error with the project teams that have utilized the GTSTRUDL program in their work. If it is determined that the noted error affected a given project, the affected utility will be notified of the error and depending upon the nature/effect of the error, additional actions may be taken.

The following information is from Chris Sward (S&L Project Manager for PE plants):

Our procedure for software control is attached (SOP0204 - proprietary). This procedure outlines all of our requirements for handling vendor software. With regard to error notification, Article 3.5.2 includes the process that Javad described.

The description for calc S06-0003 in the EC discusses where results are close, but does not explain why such large differences in results for moment can be ignored in demonstrating that the new model is reasonable for use for design purposes. Need to strengthen discussion for why new model is acceptable for use (e.g., state of the art modeling, use of as-built info, manual cross-check, third party reviews, etc.)

51 (Technical) S06-0003, purpose - States that benchmarking of new model was limited to load combination for change in pre-stress. A caution should be added to the calculation that if this model is used for other load cases, additional benchmarking may be required.

This model was used to benchmark dead load + 1.15 accident pressure + prestress because that was the only load case for which existing design basis results are available. Additional benchmarking (against existing design basis calculations is not possible because there are no additional results for other load cases available. Refer to Section B.6-p for an evaluation as to why the FEM models are acceptable. Based on these conclusions the stated purpose of calc S06-0003 is correct.

D.0 Is it appropriate to defer piping connections for the required water supply and waste water discharge piping to the settling ponds to be handled by work orders?

Who will be responsible for handling this?

Who is the containment opening task manager and how will he address obtaining the required water volume for the hydrodemolition, i.e. what process will be used to insure that this happens?

It should be noted that during plant cool down, CR-3 will begin a condensate release to the settling ponds. As soon as we get to mode 5, we will be releasing condensate as fast as permitted (300 gpm max) in order to drain the secondary system to allow work to commence. This could add approximately 500,000 gallons of condensate to the settling ponds. This needs to be taken into consideration when assessing the available volume in the ponds.

I The details for water supply and disposal for concrete removal will be included and approved per Work Order Task 1165094-Task-03. The EC identifies and evaluates the critical characteristics for water supply and disposal in Section B.6.6 and B.6.12, i.e.

" disposal of maximum. 2,000,000 gallons of water, with samples (for RP and chemical testing) being taken at the collection 'tank prior to delivery to Mac and Macs water treatment plant Final testing for Ph only, prior to discharge.

Supply and discharge piping will use either existing piping or will be field run. The present plan is for Mac and Mac to supply and field route the discharge piping.

We have identified in the installation instructions (D.2.1.3) and Sections B.6.6 and B.6.12 that approximately 500,000 gallons of condensate may be added to the settlinq ponds durinq plant cool down.

The temperatures identified in B.4.4 are the ambient air temperatures. The design basis operating and accident temperature profiles through the containment wall are shown in the Containment DBD in the section for "Containment-General" under the heading "Thermal". The Table of design temperatures shown in that section of the DBD are for the winter condition because this will yield the worst case temperature differential between the inside of containment and the outside.
